Proximie is on a mission to improve healthcare by transforming the world's operating rooms into connected ecosystems of people, devices, and data. Our Intelligence Suite transforms operating room (OR) performance, keeping teams in sync and workflows on track to maximise throughput. Simultaneously our computer vision and AI capabilities capture real time data and detect surgical events - improving quality of data outputs. The result: ORs are optimised like never before - with predictive analytics and automated notifications ensuring patients and staff are in the right place at the right time. Once practitioners are in the OR, our Surgical Suite enables real time remote access and creates a secure video record of every procedure; improving training, education, and collaboration. It is an intuitive asset which helps instil a culture of continuous learning, accelerates the adoption of cutting edge medical devices, and enhances surgical performance across the entire global workforce - improving outcomes and saving lives. Proximie was commercialised in 2019 and is available in over 500 facilities globally. Position Overview The Chief of Staff, CEO Office will report directly to Proximie's Founder and CEO, Dr. Nadine Hachach Haram, and will be responsible for the management of the Office of the CEO. You will work directly with Nadine on the things that sit at the intersection of strategy, culture, and commercial momentum - genuinely sharing in her responsibilities as CEO. This is not an operational cadence or executive assistant role. Proximie has strong leaders in Product, Engineering, Finance, Commercial, and Operations who own the rhythm of the business and the operating cadence that many Chiefs of Staff spend most of their time on (board meetings, leadership meetings, OKRs, and the like) is well covered. Equally, with an exceptional EA in the CEO office and a genuinely talented executive team that Nadine delegates a lot to, those bases are well covered. What this role is about is what remains: the harder, more ambiguous work that sits at the centre of Nadine's role as CEO - the things that only she should be doing, and that we need another exceptional person to help extend the reach of. This role offers one of the broadest and most accelerated learning experiences in health tech - working at the side of a female pioneer of the global healthtech community. Responsibilities Strategic signal and pattern recognition - live close to the front lines, converse with customers, work with commercial teams, synthesize data, and provide clear strategic insight to Nadine and the leadership team. Cross functional programme management - take ownership of the CEO's highest priority strategic initiatives, translate vision into actionable programmes, drive accountability across teams, and ensure follow through. Culture and high performance scaling - build and embed frameworks, behaviours, and leadership principles that define great at Proximie, ensuring every new hire understands what we do, how, and why. Executive relationship management - support Nadine in building and deepening senior relationships with health system executives, MedTech partners, and strategic accounts that require CEO level engagement, representing Proximie with credibility and care. Who You Are You have at least 6+ years of experience, likely in management consulting, investment banking, a high growth startup, or a combination. You may have been in a Chief of Staff or senior strategy role before, or this may be the natural next step from a strong operational or advisory career. You are exceptionally clear in your thinking and your communication - written and verbal. You can distil complexity into simple, compelling narratives. You move fast and finish things. You don't need to be told twice, and you hold yourself to a high standard without needing external accountability. You are deeply curious about the business - customers, market, and what's working - and you're willing to find the answer rather than wait for it. You can work at both altitude and ground level. You're as comfortable shaping a strategic framework as you are turning it into a working document by end of day. You are someone people trust. You handle sensitive information with discretion and build relationships based on substance, not proximity to power. You care about the mission. Proximie is a company trying to improve healthcare outcomes globally. That means something to you. Why This Role, Why Now? Proximie is at an inflection point. The OR intelligence market is opening up, our platform is maturing, and the opportunity to set the standard for how ORs operate globally is real and immediate. Nadine leads this company with an intensity and a purpose that comes from having stood in an operating theatre and seen what broken healthcare looks like. This role is for someone who wants to learn from that, contribute to it, and be changed by it. In this role, you will sit at the centre of a scaling health tech company through one of its most consequential periods of growth. That is rare. We want someone who knows it. Why Work for Proximie? You will be encouraged to grow in your role, take ownership and gain responsibilities. Proximie's values are Ownership, Deliver Results, Build Trust and Go Beyond. Generous annual leave. Two "well being" days per year plus the day off for your birthday. "Summer Fridays" - early office closing on Fridays during summer months. Annual bonus programme - based on individual contribution. To support your professional growth, all permanent employees will have access to an annual stipend of £1,000 to assist with personal development activities. Flexible working hours - we trust our people to manage their time and focus on wider results. A flat organisational structure where every opinion matters, ideas are cultivated, and innovation is encouraged. Proximie is a truly global company with teams across the UK, Europe, United States and the Middle East - giving you opportunities to see the world. Proximie is an equal opportunity employer. We are committed to providing a work environment that supports, inspires, and respects all individuals. We do not discriminate on the basis of race, colour, religion, marital status, age, national origin, ancestry, physical or mental disability, medical condition, pregnancy, genetic information, gender, sexual orientation, gender identity or expression, veteran status, or any other status protected under the law.

The Opportunity This is your chance to build the foundational systems for 'Citi Assist', a Generative AI assistant that will reach every Citi employee globally. You'll join us on the ground floor, becoming a core builder on a high-visibility platform that sets the standard for how a global bank adopts this technology safely and at scale. As a polyglot engineer, you'll work across the full stack. That means crafting intuitive user interfaces one day and building robust backend APIs the next. You'll be equally excited about both. What You'll Do Build and deliver across the stack. This is a hands on role where you'll write high quality, tested code and move features from idea to production. Sometimes that's a user facing component. Sometimes it's a backend API. Often it's both. Own your features end to end. You'll take responsibility from the UI to the database. That means figuring out the path forward, asking the right questions, and driving your work to completion with support from the team. Build with security in mind. For us, building safe, sound, and compliant systems is non negotiable and part of our craft. You'll implement security best practices in everything you build, including navigating the emerging challenges of AI safety. Be a great teammate. We expect you to be an active participant in our engineering culture. That means offering and receiving constructive code reviews, helping your peers when they're blocked, and sharing what you learn. We succeed as a team. Communicate proactively. We value open communication about progress and blockers. This helps us support each other effectively and keeps the whole team aligned. No one should have to chase you for updates. What We're Looking For We know that people from underrepresented groups are less likely to apply if they don't meet 100% of the criteria. If you're excited about this role but your experience doesn't align perfectly with every qualification, we encourage you to apply anyway. You may be just the right candidate for this or other roles. You should have Experience building and deploying production applications, whether that's frontend, backend, or both Proficiency in at least two of these languages: Python, TypeScript/JavaScript, Go, or Java Experience building user facing features with modern frontend frameworks like React, Vue, or Angular Experience building backend services and APIs that are reliable and maintainable Comfort with containerised environments (we use OpenShift, but Kubernetes or Docker experience transfers well) Practical experience with CI/CD pipelines and a belief in automating things Solid experience working with relational databases like Postgres or MySQL What matters most to us A solutions first mindset. You find the best path to solve the problem, whether that's writing new code, improving an old system, or integrating the right tool. The outcome is what matters. A bias for action and a focus on shipping. You understand our goal is to deliver value to users, not just to write perfect code. You know when to be pragmatic and when to invest in technical excellence. Clear communication and collaboration. You're proactive about sharing your progress and asking for help when you need it. You understand that keeping the team aligned helps everyone succeed. A collaborative spirit. You find satisfaction in building high quality software and you thrive in a team environment where you can learn from and help your peers. A security conscious approach. You see security and safety as part of the job, not an afterthought. Bonus points for Direct experience with Generative AI concepts, LLMs, or related personal or professional projects Contributions to open source projects or a portfolio that demonstrates your range Experience working in highly regulated environments Our Tech Stack We work with Python, TypeScript, Go, and Java on the backend. Our frontend is built with TypeScript, React, and Next.js. We use Postgres for our database, run everything on Kubernetes (specifically Red Hat OpenShift), and our DevOps setup includes GitHub and CI/CD tools like Tekton and Harness. Our Team and Mission We're the Common Platform Engineering team for GenAI, a central group in the Chief Technology Office. We're a focused agile team that owns our work from idea to production. Our culture is built on a shared belief in engineering craftsmanship, backed by leadership that actually understands what that means. We're on a journey to prove what's possible inside a large organisation, and that means navigating some legacy while building the future. This isn't a role for someone who wants everything to be perfect on day one. It's for an engineer who wants to be part of the team that gets us there. We have a dual mission. First, we're building 'Citi Assist', the GenAI digital assistant for our colleagues. Second, we're providing the platforms and guidance that enable the entire organisation to adopt GenAI safely and effectively. This is not a typical banking job. We'll build foundational technology together that has a direct, positive impact on hundreds of thousands of people. We'll tackle big problems as a team, with executive support behind us. We'll shape our solutions collaboratively, learning from each other along the way. You'll have real autonomy in your work, but you'll never be on your own. What we'll provide you This is a unique role that will put you in the position to be part of a new venture and actively drive change. Every day there will be new challenges that will help you develop new skills that can drive your career. By joining Citi London, you will not only be part of a business casual workplace with a hybrid working model (up to 2 days working at home per week), but also receive a competitive base salary (which is annually reviewed), and enjoy a whole host of additional benefits such as: 27 days annual leave (plus bank holidays) Discretionary annual performance related bonus Private Medical Care & Life Insurance Employee Assistance Program Pension Plan Paid Parental Leave Special discounts for employees, family, and friends Visit our Global Benefits page to learn more.

You'll join us on the ground floor, becoming a core builder on a high-visibility platform that sets the standard for how a global bank adopts this technology safely and at scale. Here's what makes this role unique: we know that data is the key to building a successful, safe, and scalable generative AI assistant. The difference between a good AI product and a great one isn't just the model-it's the testing, evaluation, and feedback loops that make it better every day. As a data-focused full-stack engineer, you'll help us craft the tools and systems that let us understand how Assist is performing, where it's succeeding, and where it needs to improve. You'll work across the stack, building everything from intuitive dashboards that surface insights to robust backend pipelines that process evaluation data at scale. What You'll Do Build the tools that make Assist great. You'll design and build the testing, evaluation, and feedback systems that help us understand how our AI assistant is performing in the real world. This means creating tools for both our team and our users to provide feedback, analyse interactions, and measure quality. Work with data across the full stack. You'll build data pipelines that collect and process evaluation metrics, create visualisations that surface insights to the team, and design APIs that power our testing infrastructure. You'll be equally comfortable writing SQL queries as you are building React components. Own your features end to end. You'll take responsibility from conception to production. That means understanding the problem we're trying to solve, designing the right solution, building it, and measuring whether it's working. You'll drive your work forward with autonomy while keeping the team aligned. Build with safety and quality in mind. For us, building safe, sound, and compliant systems is non negotiable. You'll help us establish the data practices and evaluation frameworks that ensure Assist meets our high standards for quality, safety, and regulatory compliance. Set the technical direction. As a VP level engineer, we expect you to influence how we approach problems. You'll mentor other engineers, contribute to architectural decisions, and help establish best practices for how we work with data across the platform. Be a great teammate. We expect you to be a leader in our engineering culture. That means offering thoughtful code reviews, unblocking your peers, sharing what you learn, and helping raise the bar for the whole team. We succeed together. What We're Looking For We know that people from underrepresented groups are less likely to apply if they don't meet 100% of the criteria. If you're excited about this role but your experience doesn't align perfectly with every qualification, we encourage you to apply anyway. You may be just the right candidate for this or other roles.

You believe that good data and rigorous evaluation are essential to building great products. You know how to instrument systems to collect the right data and how to turn that data into actionable insights. A solutions first approach. You find the best path to solve the problem, whether that's building new infrastructure, leveraging existing tools, or changing how we think about the problem entirely. You're pragmatic about trade offs. Technical leadership. You have strong opinions, loosely held. You can articulate your technical vision and bring others along with you, but you're also open to being wrong and learning from your peers. A focus on impact. You understand that our goal is to deliver value to users and make Assist better every day. You know when to move fast and when to invest in building things properly. Clear communication and ownership. You take initiative, communicate proactively, and take responsibility for outcomes. You don't wait for permission, but you keep stakeholders informed. A collaborative spirit. You thrive in team environments where you can learn from others and help them grow. You see mentoring and knowledge sharing as part of your role. Bonus Points For Direct experience building evaluation or testing frameworks for AI/ML systems Experience with LLM evaluation techniques, prompt engineering, or AI safety concepts Experience with data pipeline tools like Apache Airflow, Dagster, or similar Experience with analytics platforms, experimentation frameworks, or A/B testing infrastructure Background in data science, analytics engineering, or similar data focused roles' Contributions to open source projects in the data or AI space Experience working in highly regulated environments Our Tech Stack We work with Python, TypeScript, Go, and Java on the backend.

Our Team and Mission We're the Common Platform Engineering team for GenAI, a central group in the Chief Technology Office. We're a focused agile team that owns our work from idea to production. Our culture is built on a shared belief in engineering craftsmanship, backed by leadership that actually understands what that means. We're on a journey to prove what's possible inside a large organisation, and that means navigating some legacy while building the future. This isn't a role for someone who wants everything to be perfect on day one. It's for an engineer who wants to help us get there, influencing how we solve problems and raising our collective bar. We have a dual mission. First, we're building 'Citi Assist', the GenAI digital assistant for our colleagues. Second, we're providing the platforms and guidance that enable the entire organisation to adopt GenAI safely and effectively. This is not a typical banking job. You'll build foundational technology that has a direct, positive impact on hundreds of thousands of people.
