Join us at a pivotal moment to help maintain and evolve our B2C products used by millions, while playing a key role in building our new B2B offering from the ground up. You'll build the TypeScript/NestJS services powering our mobile app and ship full-stack features (backend through frontend) on our web products. Who You Are You're a Product Engineer first, an engineer second. Code is a tool, the goal is user value and business impact. You're backend-heavy and full-stack capable. Your home base is backend (TypeScript/NestJS), and you ship full-stack on the web (React/Next.js/similar) when the work calls for it. Angular & Vue experience is fine! You build for mobile without building the mobile app. You design APIs and services that serve mobile clients beautifully, accounting for offline, network, battery, and app-release realities and are able to partner closely with mobile engineers. You own features end-to-end. From API design and data modelling to web frontend implementation, deployment, and post-launch iteration. You're a proactive collaborator. You ask the right questions, propose solutions, and work effectively with teammates whose depth complements yours, including mobile, design, and product. You thrive in fast-paced, early-stage environments where speed, user feedback, and product-market fit drive decisions. What You Bring You have strong backend depth in TypeScript and NestJS (or comparable Node.js frameworks). You bring solid web frontend skills with React, Next.js, or similar enough to ship polished, production-quality interfaces independently. You have a working knowledge of cloud infrastructure; ideally GCP (Cloud Run, Cloud Functions, Firestore), CI/CD pipelines, and event-driven patterns (BullMQ/Redis or similar). You can ship and operate your own services. You have awareness of mobile constraints. You know what makes an API painful or delightful to consume from a mobile client, even if you don't write the mobile code yourself. You value pragmatism over purism. You make calibrated calls on architecture, scale, and tech debt based on what the product actually needs. How You Work You push back on the why, not just the how. You ask "why are we building this?" before "how do we build this?" You propose simpler alternatives when a 3-day version captures 90% of a 3-week feature's value. You're comfortable telling PMs and designers when something isn't worth building. You treat technical debt as a tool. You ship throwaway prototypes to validate hypotheses with real users. You delete what flops and re-architect what succeeds. You know when "the right way" is a luxury vs. a necessity, and can tell the difference. "Done" to you means users are using it. A merged PR isn't done. A feature is done when it's live, adopted, and the metrics prove it was worth building. You actively monitor analytics post-launch. You're a strategic partner. You sit with PMs and designers to shape what we build and what we don't. You're as comfortable in a product strategy conversation as you are in a code review. You contribute insights from user data, technical constraints, and implementation realities to inform product decisions. Must be based and have the right to work in the United Kingdom.

Technical Implementation Lead - 12-month fixed term contract Location: London Business Area: Marketing and Public Relations Ref #: Description & Requirements Technical Implementation Lead - 12-month contract Last year, the South African G20 Presidency helped to deliver a global first for international carbon market infrastructure - a voluntary, common foundation for carbon credit data standardisation, known as the Common Carbon Credit Data Model ('Data Model'). The Data Model provides guidance on standardisation of key data fields across the carbon credit lifecycle, from pre issuance to retirement. This is a critical step to resolving one of the market infrastructure obstacles that prevents carbon credit markets from scaling - and channeling potential tens of billions of annual, debt free dollars to emerging markets and developing economies. The CDSC was established in 2022 by French President Emmanuel Macron and United Nations Special Envoy on Climate Ambition and Solutions Michael R. Bloomberg. Chaired by Mary Schapiro, the CDSC brings together global policymakers, regulators, and international organisations, informed by data providers and civil society, to improve access to standardised climate data. The Climate Data Steering Committee (CDSC) Secretariat was the Lead Knowledge Partner on the development of the Data Model and is now piloting and testing it with interested jurisdictions and market participants. This role is therefore a unique and exciting opportunity for the right candidate to bring to bear deep technical skills in support of a project with global reach and impact. It would also offer unparalleled opportunity to gain insight into how to support effective policy making around carbon markets across a set of major markets and the wider private sector. What's the role? We are looking for someone who has experience mapping data models and designing data schemas to join our team and support work to pilot the Data Model with carbon market participants such as registries, exchanges, and project developers, as well as with policymakers and regulators. The candidate would ideally have an understanding of the opportunities and challenges relating to data standardisation and a strong interest in learning more about carbon markets. In return, we can offer an insight into how to progress globally influential work, involving governments, standard setting bodies and the wider carbon markets ecosystem. The role will involve travel to support our global work. We'll trust you to: Work with a team to support countries and market participants - in piloting the Data Model - to map data schemas, pilot workflows, and test data interoperability across their data systems Develop written and technical resources to support piloting and voluntary adoption, for example data mapping tables, user guides, stakeholder role matrixes, etc. Work closely with carbon market infrastructure providers and engineering teams to embed the Data Model in schemas, APIs, exchange protocols and other technical infrastructure Outline technical roadmaps to support piloting and collaborate with the CDSC Secretariat to manage timelines, deliverables, and tracking of actions for piloting partners Create and maintain processes for updating the Data Model in response to feedback from the pilots and public consultation, balancing data standardisation best practices and policymaker/market needs Synthesise technical findings and complex topics to senior stakeholders in an accessible manner We'll need you to have: A bachelor's degree in a quantitative subject - information sciences, computer sciences or related discipline preferred At least 3 years of professional experience with strong analytic skills in mapping standards into data models and creating mappings between them to test interoperability Demonstrable expertise in designing/architecting data schemas as well as implementing and productionising them, including proficiency in Excel and coding languages such as SQL or Python Familiarity with relational databases and data modelling tools Experience working with APIs and other applications to exchange data Understanding of data management discipline, including overarching data model maintenance and governance processes Experience working across multiple teams or projects and delivering to tight deadlines A willingness to travel with us to support brief periods of work in specific countries with either public or private sector stakeholders A collaborative approach and exceptional relationship building and communication skills - both written and verbal We'd love to see: Familiarity with carbon credit markets Experience engineering backend data infrastructure, ideally (but not necessarily) with a relevant organisation - for example with an emissions inventory or carbon credit registry Familiarity with financial markets data and market infrastructure best practices If indicated, please note that years of experience are a guide; we will consider applications from all candidates who can demonstrate the skills necessary for the role. Bloomberg is an equal opportunity employer and we value diversity at our company. We do not discriminate on the basis of age, ancestry, color, gender identity or expression, genetic predisposition or carrier status, marital status, national or ethnic origin, race, religion or belief, sex, sexual orientation, sexual and other reproductive health decisions, parental or caring status, physical or mental disability, pregnancy or parental leave, protected veteran status, status as a victim of domestic violence, or any other classification protected by applicable law.
