Principal Software 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 an exceptional, product-minded full-stack software engineer to join our engineering team and help scale Omnea. We’re on track to grow from double-digit customers to over 200 enterprise clients and 10x our revenue—all within the next 2–3 years. You'll play a key role in driving the growth of our product, team, and company as we transition from ‘start-up’ to ‘scale-up’.

You’ll be joining us at a pivotal moment. We recently closed $50M in Series B funding from Khosla Ventures, Insight Partners, Accel, Point Nine, and First Round Capital. Over the past year, we’ve grown revenue 5x, tripled our customer base, and maintained over 99% retention with enterprises like Spotify, Wise, Albertsons, Adecco, and McAfee. Our tight-knit, high-calibre team reflects our rigorous hiring process—it took more than 10,000 interviews to hire our first 50 Omneans.

Now, we’re scaling rapidly and pioneering the AI Supplier Relationship Management category. We’re looking for the best software engineers to help transform procurement into a true competitive advantage!

You'll need to participate in our pair-programming interview stage using JavaScript or TypeScript, and you’ll be evaluated as if that has been your main language. As we're hiring for full-stack roles, this position isn't ideal if your experience is solely in frontend, backend, devops/platform, or primarily in another language (e.g., Java).

While we value skills over years of experience, candidates at this level typically have around 12–15+ years of software engineering experience.

As a Principal Engineer at Omnea, you’ll remain hands-on, actively contributing code, and leading through technical execution and ownership—not simply through meetings or high-level architecture discussions.

• Join a Skilled Team: Become part of one of Europe’s fastest-growing early-stage companies, working alongside experienced full-stack product engineers with backgrounds at top technology firms.

• Direct Product Impact: Have a voice in core product decisions, including prioritizing the roadmap, defining project scopes, and technical direction. Influence product strategy, user experience, and technical feasibility to drive our roadmap to success.

• Work with Modern Tech: Omnea is built on cloud-native, serverless technologies. Our stack features TypeScript with React & Material UI, Postgres, Hasura, and AWS Serverless Technologies like Lambda, DynamoDB, and EventBridge—all managed with 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 take full ownership of your projects—from product and design decisions through to deployment, monitoring, and impact measurement. You’ll work across the stack, from DevOps to UI, taking initiative and driving continuous improvement.

• Continuous Delivery: We practice continuous delivery, deploying small, incremental changes to production multiple times per day. This keeps our systems agile and responsive to both customer needs and technical challenges.

• Scalability Challenges: As we expand from tens to hundreds of customers and enter new product domains, you’ll help us scale our product, architecture, and processes while maintaining performance and reliability.

• Collaboration & Autonomy: Enjoy the freedom to lead your projects independently and make key decisions, while benefiting from a collaborative, high-trust team environment that comes together for challenging problems.

• Customers at the Centre: We value rapid, thoughtful responses to customer feedback and issues. You’ll have opportunities to engage directly with customers, understand their experience, and iterate to deliver solutions that delight them.

• You’re experienced (typically 12–15+ years) building web apps, having designed and implemented full-stack features from start to finish using TypeScript (and ideally AWS).

• You focus on impact. You’ve led the engineering of critical systems, working with advanced AWS, IaC, observability, and quality tools, and you’re eager to bring this mindset to an early-stage startup.

• You know what excellence looks like. You build highly reliable, well-architected products with quality, observability, and redundancy in mind.

• You’re ready to get things done. You love every part of building a product, and you’re comfortable moving across the stack as needed. You enjoy problem-solving, thinking from first principles, and learning new skills quickly.

• You crave ownership. You naturally gravitate toward complex engineering challenges and are eager to take on big projects—whether that means deepening your DevOps or SRE skills or taking responsibility for key initiatives.

• You help build the team. You enjoy maximizing team performance, whether by learning from others or by providing feedback, mentoring, and uplifting those around you.

• You’re comfortable with ambiguity. You confidently tackle open-ended problems and make decisions with autonomy, all with the support of an experienced team.

Nice-to-haves that really stand out:

• You have excelled in another area in the past—whether in academics, sports, work, or elsewhere—demonstrating that you consistently go above and beyond.

• You have a genuine passion for engineering that extends beyond your job. You contribute to open-source projects or work on side projects in your spare time simply because you enjoy it. You are confident in your ability to solve ambiguous problems and consistently produce high-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

• We're commercial, ambitious and we don't pretend otherwise! We're actively seeking folks looking to make the most of a career-defining opportunity, with the hunger to be part of building something really impressive. You can see our values here

• We sometimes use AI note-takers to help us transcribe interview notes, so we can be more present in your interview. If you'd like to opt out of us using automatic transcribers, please note this in the free text field in your application, otherwise we'll take your application as confirmation that you're happy for us to use notetakers (whether added to video calls or in the background).

We are proud to be recognised for both our culture and product, and we are just getting started. Join us as we grow!
