Junior Full Stack Engineer

At Omnea, we’re reinventing how enterprise businesses operate, starting with the most painful parts: procurement – where a single purchase can drag on for months, trigger 50+ emails, and pull in Finance, Legal, Security, and IT just to get something approved.

We’ve raised $75M from Khosla Ventures, Insight Partners, and Accel to change that. Our AI-native platform connects every person, step, and system so buying is fast, safe, and efficient – one place to request, automated approvals and renewals, real-time supplier risk, and complete spend visibility.

It's a $7B+ untapped market, and our traction reflects the scale of the opportunity: we’ve 10x’d ARR to double-digit millions in 18 months and are trusted by global enterprises like Spotify, MongoDB, Monzo, and Albertsons. We’re now the 4th fastest growing startup in Europe.

Our team previously scaled Tessian (cybersecurity tech, backed by Sequoia, Balderton, Accel, acquired post-Series C), and our team includes ex-founders operators who’ve grown unicorns, shipped world-class products, and executed at the highest levels. You’ll work alongside leaders like Ben, Abs, Sabrina, and Rebe.

We’re seeking exceptional, product-minded full-stack software engineers to help drive Omnea through its next phase of growth.

In the past 18 months, we’ve achieved a 10x growth in revenue, tripled our customer base, and maintained over 99% retention with enterprise customers such as Spotify, Wise, Albertsons, Adecco, and McAfee. Our standards are intentionally high—it took us more than 10,000 interviews to hire our first 50 Omneans. Now, we’re scaling from low double-digit to 200+ enterprise customers, aiming for another 10x increase in revenue over the next 2–3 years.

You’d be joining at a pivotal moment: past product-market fit, but early enough to obtain meaningful ownership and influence as we transition from startup to scale-up. We’re a Series B company with $75m raised from Insight Partners, Khosla Ventures, Accel, and over 50 respected founders and operators. Our leadership team, including the CEO, CCO, and CFO, previously helped scale Tessian from $0–30m ARR and from pre-seed to Series C, so we’ve navigated this path before.

Over the last 18 months, we’ve built and deployed Omnea with some of the world’s leading tech companies—including Spotify, Monzo, Lookout, McAfee, Onfido, Typeform, and Proofpoint—while remaining lean and execution-focused. Now, we're ready to scale the product, the team, and our ambitions.

We want outstanding engineers who are eager to help build one of Europe’s defining enterprise software companies.

We’re flexible with 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 now lean more towards frontend or backend, as long as you’re excited to grow into a full-stack role.

If you seek real ownership, meaningful technical challenges, and the chance to help shape a scaling company, we’d love for you to join us.

• Join a Skilled Team. You'll become part of one of Europe's best and fastest-growing startups, working alongside experienced full-stack product engineers—high performers from other top-tier tech companies.

• Direct Product Impact. You’ll help shape key product decisions, including prioritising the roadmap, defining project scopes, and the technical direction. You'll play an important role in discussions about strategy, user experience, and feasibility, ensuring our roadmap leads to success.

• Work with Modern Tech. Omnea is built entirely on cloud-native and serverless technologies. Our main stack uses TypeScript with React and Material UI, Postgres, and AWS Serverless tools like Lambda, DynamoDB, and EventBridge—all managed through 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 have complete ownership of your projects—from product, design, and architecture, through to deployment, monitoring, and measuring user impact. You’ll work across the stack, touching everything from DevOps to UI styling. We expect everyone to take initiative, proactively solve problems, and look for continuous improvements.

• Continuous Delivery. We embrace continuous delivery to keep our systems agile, responsive, and safe. You’ll deploy small, incremental changes to production multiple times a day, delivering steady improvements and adapting quickly to customer needs and technical challenges.

• Tackle Scalability Challenges. As we expand our customer base from tens to hundreds and move into new product areas, you’ll help us scale our product, architecture, and processes while maintaining performance and reliability.

• Collaboration & Autonomy. You’ll often work independently, taking charge of your projects and driving them forward. Yet, we remain a lean, high-trust team—ready to collaborate and support each other with tough challenges.

• Customers at the Centre. Responding promptly to customer feedback and issues is essential. We encourage engaging with customers, understanding their experiences, and iterating based on their input to deliver solutions that genuinely delight them.

• You have a few years' experience. You have proven experience shipping production web applications—from concept to deployment—ideally in a full-stack TypeScript and AWS environment.

• You're focused on impact. Driven by impact, you’re eager to contribute to systems that matter. You want to learn how strong engineering practices, cloud infrastructure, observability, and testing come together in a fast-moving startup.

• You know what good looks like. You care deeply about high-quality engineering and strive to raise the bar in your work. You want to build reliable, well-architected products and are intentional about quality as you develop your judgement.

• You're ready to achieve a lot. You enjoy every aspect of building a product and are comfortable moving across the stack as needed. You love problem-solving and thinking from first principles. You get satisfaction from delivering results, are quick to learn new skills, and apply them immediately.

• You crave ownership. You actively seek responsibility and bigger challenges, whether deepening your product expertise or building strength in infrastructure, DevOps, or reliability.

• You're a team builder. You want to be part of a high-performing team and take this seriously. You’re invested in learning from others, sharing context, giving clear feedback, and helping the team move faster and do better work.

• You're comfortable with ambiguity. Energised by uncertainty and momentum, you’re happy to tackle unclear problems, form a point of view, and iterate toward a solution—using support and guidance from your experienced teammates along the way.

Nice to haves that really stand out:

• You’ve excelled at something before—academics, sport, work, or any area where you’ve gone above and beyond.

• You love engineering. It’s more than a job; it’s a passion. Perhaps you've contributed to open-source or worked on side projects simply because you enjoy it. You’re confident tackling ambiguous problems and delivering quality code.
