At Deskpro, we make helpdesk software and we have customers of all shapes and sizes from across the globe, including Vodafone, Microsoft, NHS, and Panasonic. Deskpro is a large product with a large variety of features and modules, from email, chat, and voice, to blog posts, knowledgebase and guides, and everything in between. There's always something new to build. We have a Wimbledon office but remote opportunities are available for UK-based candidates. What you will do as a senior full-stack engineer As a senior full-stack engineer, you will help build new features and modules, you'll be involved in shaping our underlying product frameworks and our internal processes like code reviews and deployment, and you'll get to participate in feature planning and have real input on the direction we take the product and the company as a whole. You'll be joining a small team where your specific experience will have a great impact. You will have a lot of autonomy over your own projects and you will get to use your expertise to lead by example. Technology we use and where we're going Deskpro is a polyglot company. A lot of our existing product backends are written in PHP (Symfony, Laravel), but as the product evolves, we're shipping NodeJS/Typescript and Golang services, too. Most of our Cloud services are serverless NodeJS/Typescript projects. We use a lot of other technologies like Elastic, Redis, and services offered by AWS like DynamoDB. We're big fans of using the right tool for the job. The main product frontend is all Typescript/React that talks to GraphQL backends. Other parts of the business use React/NextJS or even Svelte. We've spent time looking at maturing technologies like Web Components and have some ideas on improving our frameworks with agnostic UI libraries through tools like Lit. Node is becoming an even bigger part of our tech stack going forward as we embark on the development of exciting new projects and features like chat bots and AI. The Node community is ever changing and we need people who know the ecosystem well to help our team make fundamental decisions. Why should you be interested? You'll get to use and learn about many different products, APIs and technologies. Deskpro is the central hub for a lot of companies, and we're always adding new features, modules and integrations. You'll get to work with real customers and get a peek into how other businesses operate. You'll get to learn about scaling software as well as scaling the SaaS platform as a whole. You'll get to try out new technology. We are constantly updating our stack and are always on the lookout for tools that will help us be more productive. You are a good fit for the role if You have an earnest interest in developing software with a desire to learn more about the craft. You enjoy taking the lead on big projects and enjoy a strong sense of ownership over the stuff you build. You have a lot of experience with Typescipt/Node as both a backend and frontend technology. You've got experience with React. Experience with NextJS specifically is ideal. You have excellent written and verbal communication skills. We are big believers in "writing stuff up", everything from spec's to dev docs to RFC's. You need to be able to know your audience and communicate clearly. You enjoy solving problems yourself and like working in a "get stuff done" environment. We're a small team and we all generally just get on with things in a fairly autonomous manner. You won't be micro-managed. Examples of projects we've been working on lately Chat bots and AI - automated real-time responses to instant messenger messages from users, including scripted responses, decision paths and flow charts. Voice Incoming and outgoing calling from the browser, including features likes automated call routing and simple IVRs. AWS Moving all our infrastructure to AWS. This has included some ambitious projects like re-writing the email parser to make it more efficient. Reports New reporting system with dashboards, scheduled reports, and sharing. Apps platform A platform that allows third parties to create "apps" that run within Deskpro. Filtering and search New filtering and search system to improve efficiency, accuracy, and UX. Social / Multi-channel messaging we are building out generic data structures with flexible ingress APIs to allow connecting Deskpro to any messaging channel including social sites like Twitter and Facebook, but we also envision integrations with systems like eBay messages or Apple/Google app stores. We'll be able to process any kind of communication. New GraphQL API backends.

About The Job In a cloud software world, who you are and what you have access to determines the risk associated with your accounts being compromised, Abnormal Security aims to build a comprehensive tool to understand the employees of our customers, and aid security professionals in assessing the risks and threats impacting their employee base. Help us build a new layer of protection that will give enterprises the same level of security for their cloud offerings as Abnormal Security's industry leading products do in the email security space. We're looking to add a Senior Engineer to our team of world class engineers. The individual in this role will shape and elevate our engineering teams within the Behavioral Security Products division. This role straddles the line of velocity and excellence. About You You are someone who wants to make an impact.

This also means occasionally we'll ask you to do things that may not strictly fit the role of a "backend engineer" - it might mean jumping on a customer call, or digging in to help fix a frontend bug. We are also not only a remote team, but a very distributed team, as such you will need to have excellent communication skills across both verbal and written mediums. You will need to be just as comfortable on a zoom call as writing a 1 pager project proposal to be shared across the team for technical feedback. What You Will Do Build and maintain high-throughput, low-latency systems that process 100s of millions of events per day to enable detection to identify notable events Help plan and lead the efforts to build out products designed to protect our enterprise customers, from medium business to some of the largest companies in the world Enhance our frameworks for improving detection efficiency and effectiveness Provide operational support to maintain a high level of system uptime and performance Create a magical work environment with colleagues and memorable interview process for candidates Must Have Experience working with building and operating distributed systems and services 5+ Years of overall software engineering experience Experience with tech stack including: Language: Python, Golang Platform: AWS Framework: Django, Spark Storage / Data Pipelines: Postgres, Redis, ElasticSearch, Kafka, Parquet Nice To Have Prior exposure to production machine learning systems.
