Our product, The Atom, is used on major projects worldwide to bring designs to life on-site and help teams build more accurately, efficiently and with fewer mistakes.\nAs a Series B business scaling across the UK, US and Europe, we’re not only evolving the technology our customers use, we’re also investing in the tools and applications that enable our own teams to operate effectively as we grow.\nWe’re looking for a Full Stack Engineer to take ownership of the internal applications, dashboards and AI-enabled tools that help power XYZ Reality behind the scenes.\nThe Role\nThis is a great opportunity for a Full Stack Engineer who enjoys building useful products, solving real business problems and owning what they create from idea through to production.\nAs XYZ has grown, teams across the business have increasingly developed applications, dashboards, automations and AI-enabled tools to solve problems and improve how they work. We now need an engineer who can bring technical ownership to this space - taking promising ideas and prototypes and turning them into secure, scalable and maintainable applications.\nYou’ll work directly with teams across XYZ to understand what they need, translate those requirements into technical solutions and build applications that people across the business will genuinely use.\nBecause these tools can interact with employee, user and potentially customer data, you’ll also ensure they are built and deployed properly, with security, maintainability and appropriate engineering standards considered from the outset.\nThis is a role with plenty of autonomy. You’ll own applications end-to-end, from architecture and data model through to UI, deployment, monitoring and ongoing iteration.\nAnd when internal priorities allow, you’ll have the opportunity to contribute your Full Stack skills to our wider product engineering team and the technology behind XYZ Reality’s engineering-grade AR platform.\nThe role is based in London on a hybrid basis, ideally 2-3 days per week in the office, enabling you to work directly with the teams you’ll be building for while retaining flexibility.\nWhat You’ll Be Doing\nDesign, build and maintain internal business applications end-to-end, from data model and architecture through to user interface.\n\nTake ownership of existing prototypes, dashboards and tools and evolve them into secure, reliable and maintainable applications.\n\nShip quickly using modern serverless and Backend-as-a-Service platforms such as Vercel, Supabase and Firebase.\n\nBuild applications using TypeScript/JavaScript, React/Next.js and Node.js.\n\nIntegrate AI capabilities, including LLM APIs, automation and agents, to improve and streamline business workflows.\n\nWork directly with stakeholders across XYZ to understand problems, gather requirements and translate business needs into practical technical solutions.\n\nOwn the full application lifecycle, including architecture, development, deployment, monitoring, maintenance and iteration.\n\nEnsure appropriate security and data protection standards are built into applications handling employee, user or customer information.\n\nImplement authentication, SSO and identity management where required.\n\nChampion good engineering practices across code quality, testing, security and CI/CD.\n\nBuild integrations between internal systems, data sources and third-party platforms.\n\nUse feedback and usage data to continually improve the applications you build.\n\nEvaluate emerging technologies and AI capabilities and identify where they can genuinely improve how XYZ operates.\n\nContribute to our wider product engineering environment when capacity allows.\n\nWhat We’re Looking For\nDemonstrable in-depth professional software engineering experience, ideally within a Full Stack role.\n\nStrong proficiency in TypeScript/JavaScript and modern web development.\n\nHands-on experience with React/Next.js and Node.js.\n\nExperience building and deploying applications using platforms such as Vercel, Supabase, Firebase or equivalent modern technologies.\n\nExperience owning applications beyond the initial build - including deployment, maintenance, monitoring and ongoing improvement.\n\nComfortable integrating AI/LLM services into applications and using modern AI tooling as part of your development workflow.\n\nExperience implementing authentication and identity management, such as OAuth/OIDC, SAML or SSO.\n\nA good understanding of application security and how to appropriately handle sensitive business and user data.\n\nStrong software engineering fundamentals, with an appreciation for maintainable code, testing and good development practices.\n\nComfortable working directly with non-technical stakeholders and turning their requirements into effective technical solutions.\n\nAble to work autonomously, prioritise effectively and take ownership of the applications you build.\n\nExperience within a startup, scale-up or modern technology environment would be particularly valuable, as would experience with Postgres/SQL, row-level security, data visualisation, reporting or workflow automation.\nWe’re looking for a strong Full Stack Engineer with solid fundamentals who is comfortable learning new tools and making pragmatic technology choices based on the problem being solved.\nAbove all, we’re looking for someone who enjoys building things that make a difference, an engineer who can take an idea or prototype, understand the problem behind it and turn it into technology the business can rely on.\nWhat You Could Be Working On\nFrom the outset, you could be working across projects including:\nInternal business applications and operational tools\n\nAI-enabled workflows and automation\n\nBusiness dashboards and reporting\n\nEmployee and talent applications\n\nData-driven internal tools\n\nIntegrations between business platforms\n\nSecure applications handling employee, user and customer data\n\nPrototypes that need to evolve into scalable, production-ready applications\n\nAs our internal technology needs continue to evolve, so will the problems you have the opportunity to solve.\nWhy Join Us\nJoin a Series B business at an exciting stage of international growth\n\nHybrid working from our London office\n\n25 days annual leave + public holidays\n\nPrivate healthcare with Vitality\n\nAdditional Christmas shutdown days\n\nBiannual salary reviews\n\nSummer & Christmas company events\n\nFree Thursday lunch and after-work gatherings\n\nEmployee referral scheme\n\nCycle to Work scheme\n\nIf you’re a Full Stack Engineer who enjoys taking ownership, shipping useful technology and using modern tools to solve real-world problems, we’d love to hear from you.","description_format":"text","description_chars":6772,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual
