Junior Full Stack Engineer in London

We’re looking for outstanding engineers who want to help build one of Europe’s defining enterprise software companies. We’re flexible on prior stack experience, but you should be comfortable completing our pair-programming interview in JavaScript or TypeScript, as that’s how we assess fundamentals. We’re also open to engineers who lean more frontend or backend today, provided you’re excited to grow into a full-stack role.

You have a few years' experience and demonstrable experience shipping production web applications, having taken features from concept to live deployment, ideally in a full-stack TypeScript and AWS environment. You focus on having a high impact and are driven by impact, eager to contribute to systems that matter. You want to learn how strong engineering practices, including cloud infrastructure, observability, and testing, come together in a fast-moving early-stage startup.

You care deeply about what good engineering looks like and are motivated to raise the bar in your own work. You want to build reliable, well-architected products and are intentional about quality as you continue to develop your judgement. You enjoy all aspects of building a product and are comfortable moving across the stack when necessary. You enjoy problem solving and thinking from first principles, motivated by getting things done and moving quickly from idea to implementation.

You actively look for ownership and responsibility, drawn to bigger or more complex problems and keen to stretch yourself, whether that’s deepening your product work or building strength in infrastructure, DevOps, or reliability. You want to be part of a high-performing team and take that seriously, invested in learning from others, sharing context, giving clear feedback, and helping the whole team move faster and do better work.

You’re energized by ambiguity and momentum, happy starting with an unclear problem, forming a point of view, and iterating towards a solution while making good use of support and guidance from experienced teammates.

Desirable: You’ve performed exceptionally at something else in the past, be it academics, sport, work etc. You’ve gone above and beyond the norm. You love engineering; it’s more than a job for you. You’ve contributed to open-source projects or worked on side-projects in your spare time just because you enjoy it. You’re confident in your ability to tackle ambiguous problems and crank out quality code.

What the job involves:

We’re looking for exceptional, product-minded full-stack software engineers to help scale Omnea through its next phase of growth. You’d be joining at a genuine inflection point: past product‑market fit, but early enough to have real ownership and influence as we move from startup to scale‑up. If you want real ownership, meaningful technical problems, and the chance to help shape a company at scale — we’d love you to build with us.

• Join a Skilled Team: You’ll become part of one of Europe’s best and fastest growing startups, working alongside a team of experienced full‑stack product engineers who were all high performers from other top‑tier tech companies.
• Direct Product Impact: You’ll be involved in key product decisions, including prioritising our product roadmap, defining project scopes, and technical direction. You’ll have a significant voice in discussions about product strategy, user experience, and technical feasibility, ensuring we steer our product roadmap towards success.
• Work with Modern Tech: Omnea is fully built on cloud‑native and serverless technologies. Our primary stack is based on TypeScript with React & Material UI, Postgres and AWS Serverless Technologies such as Lambda, DynamoDB and EventBridge – all managed via AWS CDK & SST. We use Sentry, Lumigo and LogRocket for observability and Github Actions for automated testing and deployment.
• End-to-End Ownership: You’ll be entrusted with end-to-end ownership of your projects, from product, design and architectural decisions, all the way to deployment, monitoring and measuring impact on users. You’ll work across the stack, covering everything from DevOps to styling.
• Continuous Delivery: We embrace continuous delivery to keep our systems agile, responsive and safe. You’ll deploy small, incremental changes to production multiple times per day, ensuring a steady stream of improvements and rapid adaptation to customer needs and technical challenges.
• Tackle Scalability Challenges: As we grow our customer base from tens to hundreds and expand into new product domains, you’ll help us scale our product, architecture and processes efficiently while maintaining performance and reliability.
• Collaboration & Autonomy: You’ll often work autonomously to take charge of your projects, make decisions, and drive your work forward. But as a lean and high‑trust team, we remain quick to collaborate and support each other with challenging problems.
• Customers at the Centre: Being really responsive to customer feedback and issues is key. We actively encourage engaging with customers, understanding their experience, and iterating our products based on their input to deliver solutions that truly delight them.
