• Staff (L4) – £110K – £150K • £25K – £60K Equity

Our compensation is based on your levelling during the interview process, which we'll assess throughout the interviews.

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 looking for an exceptional, product-minded Team Leader – Staff Software Engineer (L4) to join our engineering team and help scale Omnea through its next phase of growth. Over the next year, our team will double in size, our enterprise customer base will grow from ~100 to 200+, and revenue will triple. This is a Staff-level role with domain-level impact, combining senior technical leadership with people leadership responsibilities. You’ll own delivery for a team, coach and develop engineers, and shape architecture and product outcomes across a broader domain, while remaining hands-on where it matters most.

You’ll be joining us at a pivotal time. We’ve just raised $50M in Series B funding from Khosla Ventures, Insight Partners, Accel, Point Nine, and First Round Capital. In the past year we’ve grown revenue 5x, tripled our customer base, and maintained >99% retention with enterprises like Spotify, Wise, Albertsons, Adecco, and McAfee. Our team is small but high-calibre -- it took over 10,000 interviews to hire our first 50 Omneans.

Now we’re scaling fast and building the category of AI Supplier Relationship Management. We’re looking for Staff-level engineers who can lead teams or initiatives while operating beyond a single team, shaping technical direction across domains and helping turn procurement into a true competitive advantage.

You should be prepared to undertake our pair-programming stage of the interview process in JavaScript or TypeScript and be assessed on that basis as if it has been your main language. This is a hands-on leadership role — we expect Team Leader – Staff engineers to lead by example through code, technical decision-making, and delivery ownership. We are hiring for full-stack engineers, so if you’re only really a frontend or a backend engineer, are mostly a devops/platform person, or have mostly been using a very different language (e.g. Java) this likely isn’t a fit for you.

We care more about skills than years of experience, but for calibration, we’d typically expect candidates at this level to have 8–10+ years of software engineering experience, including meaningful experience leading teams or complex technical initiatives.

• Join a Skilled Team. You’ll lead and work alongside a team of experienced full-stack product engineers in one of Europe’s fastest-growing early-stage companies. As a Team Leader – Staff Engineer, you’ll be accountable for helping a group of engineers succeed, while also raising the bar across the wider engineering organisation. Everyone on the team has a strong track record of high performance at top technology companies, and we hold a high bar for quality, ownership, and impact.

• Direct Product Impact. You’ll have significant influence over product direction and execution. This includes shaping the product roadmap with Product and Design, defining project scopes, making architectural decisions, and ensuring technical trade-offs align with business and customer goals. At this level, your impact often spans multiple teams or systems, translating ambiguous objectives into clear, high-impact execution plans.

• Work with Modern Tech. Omnea is fully built on cloud-native and serverless technologies. Our primary stack includes TypeScript, React & Material UI, Postgres, Hasura, and AWS serverless services such as Lambda, DynamoDB, and EventBridge — all managed via AWS CDK & SST. We use Sentry, Lumigo, and LogRocket for observability, and GitHub Actions for CI/CD. As a Team Leader, you’ll help set technical standards, guide best practices, and ensure consistency across teams and systems.

• End-to-end Ownership. You’ll own delivery outcomes end-to-end for a team or initiative — from product discovery and technical design through to deployment, monitoring, and measuring customer impact. You’ll be accountable for quality, reliability, and velocity, while empowering engineers to take initiative and continuously improve how work gets done.

• Continuous Delivery. We embrace continuous delivery to keep our systems agile, safe, and responsive. You’ll help ensure your team ships small, incremental changes to production multiple times per day, balancing speed with robustness, operational excellence, and long-term maintainability.

• Tackle Scalability Challenges. As Omnea scales from tens to hundreds of enterprise customers and expands into new product domains, you’ll lead teams through significant scalability challenges, evolving architecture, processes, and technical standards while maintaining performance and reliability.

• Collaboration & Autonomy. You’ll operate with significant autonomy, owning decisions within your domain and driving work forward. While you may be embedded with a specific team, your scope and influence are broader by default, collaborating closely with other engineering leaders and cross-functional partners to solve hard problems and align on strategy.

• Customers at the Centre. Customer impact sits at the heart of everything we do. You’ll work closely with Product, Sales, and Customer teams to prioritise work based on customer feedback and issues, respond quickly to incidents, and ensure delivery decisions consistently maximise customer value across the product.

• You’re experienced (not a hard rule, but typically 8–10+ years) building and leading the delivery of web apps, having designed and implemented features from start to finish (full-stack, using TypeScript and ideally AWS).

• You focus on having a high impact. You've led teams or owned delivery for critical systems and initiatives, working with best-in-class tooling in AWS, IaC, observability and quality assessments. You want to discover the best ways to bring this experience to a fast-scaling startup.

• You know what good can look like. You understand what it takes to build highly reliable, well-architected systems at scale. You set and promote high standards for code quality, testing, observability, and operational excellence — and help others do the same.

• You’re ready to get a lot done. 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. You’re comfortable navigating ambiguity and keeping teams moving forward.

• You’re someone who craves ownership. Maybe you find yourself gravitating towards the meatier engineering problems. You enjoy owning delivery outcomes, setting direction, making prioritisation decisions, and unblocking teams when work gets stuck.

• You’re a team builder. You're a team player. You're excited by helping maximise team performance, whether that requires you to learn from others or to take the time to explain things, provide actionable feedback, mentor engineers, or act as the engineering “voice” for a group.

• You’re comfortable when faced with ambiguity. You're happy to tackle problems without a predefined clear definition or obvious solution, leading teams from vague goals to clear execution plans, all whilst having the support of an experienced team alongside you.

Nice to haves that really stand out to us

• 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.

At Omnea, we embrace diversity. To build a product that's loved by everyone, we're best served by a team with all sorts of backgrounds, experiences, and perspectives. We encourage you to apply even if your experience doesn't quite match the full job spec! And regardless of your race, religion, colour, gender, or anything else! If you think you could be a good fit for Omnea, please reach out.

• We work Tuesdays, Wednesdays & Thursdays in-person at our offices. At this early stage of our company life-cycle it's important to us that we get this together-time, and you can read more about why we believe this is a winning move here
