Our Mission 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. What we're looking for We're looking for an exceptional, product-minded Team Leader - Senior Software Engineer 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. In this role, you'll take on additional responsibility for technical leadership, delivery ownership, and real product impact, helping guide Omnea as we continue the transition from start-up to scale-up. 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 senior engineers who want to combine hands-on technical excellence with leading delivery, shaping direction, and acting as a strong technical voice within a team. This role is for Level 3 (Senior) engineers. We care far more about impact and skill than years of experience, but typically candidates at this level have 5+ years of software engineering experience. You should be prepared to undertake our pair-programming interview stage in Javascript or Typescript, and you'll be assessed as if this has been your primary language. This is a full-stack role - if you are only frontend, only backend, or primarily DevOps/platform focused, this likely isn't a fit. What Can You Expect in our Tech team? Join a Skilled Team. You'll become part of one of Europe's fastest-growing early-stage companies, working alongside experienced full-stack product engineers from some of the best tech companies out there. As a Team Leader at L3, you help raise the bar within your team through strong technical judgement, collaboration, and example - not hierarchy. Direct Product & Delivery Impact. You'll work closely with Product, Sales, and Customer teams to ensure your team's work is tightly aligned with company goals and customer needs. You'll help translate broader goals into a clear, prioritised plan for your team and ensure consistent, high-quality delivery. 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 own outcomes, not just output. You take responsibility for the delivery and quality of work within your team's problem space - from shaping solutions and making technical decisions, through to shipping, monitoring, and iterating. You'll remain strongly hands-on, contributing directly to building and shipping product. Continuous Delivery. We embrace continuous delivery to keep our systems agile, responsive, and safe. You'll help your team maintain a fast, reliable delivery cadence, deploying small, incremental changes to production and responding quickly to feedback. Tackle Scalability Challenges. As our customer base grows from tens to hundreds and we expand into new product domains, you'll help scale our product, architecture, and engineering processes while maintaining performance, reliability, and developer velocity. Collaboration & Autonomy. You'll operate with a high degree of autonomy in how work gets done. While you may be the primary technical voice within your team, we don't operate with rigid hierarchies - engineers at all levels collaborate, challenge ideas, and support one another. Customers at the Centre. You'll ensure your team stays close to customers. That means responding quickly to feedback, partnering with Sales and Customer teams on issues and opportunities, and continuously iterating to deliver solutions that genuinely delight enterprise users. About You You're experienced. You're an experienced software engineer (typically 5+ years - not a hard rule) with a strong track record of shipping high-quality, production systems and features end-to-end, ideally using Typescript and AWS. You focus on having a high impact. You care deeply about outcomes, not just output. You're comfortable owning delivery for a broader problem space, turning ambiguous goals into structured plans, and ensuring your team executes effectively. You know what good can look like. You understand how to build reliable, well-architected systems and make trade-offs with quality, observability, and long-term maintainability front of mind. You're ready to get a lot done. You're still hands-on technically, comfortable moving across the stack, and excited to solve hard problems from first principles while learning and adapting quickly. You're someone who craves ownership. You naturally gravitate towards responsibility - whether that's leading delivery, supporting teammates, improving systems, or taking on complex technical challenges. You're a strong team contributor. You enjoy helping other engineers unblock technical challenges, offering feedback, and acting as a trusted technical voice within the team - without needing formal people management responsibility. You're comfortable when faced with ambiguity. You enjoy tackling problems without a clearly defined solution, making decisions with imperfect information, and iterating quickly with the support of a high-trust team. 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. A few things to note: We work Tuesdays, Wednesdays & Thursdays in-person at our offices.
