Full Stack Software Engineer - Mid-level in London

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 full-stack software engineer to join our engineering team & help scale Omnea with us. Our team will grow from low double-digit to 200+ enterprise customers and through 10x revenue growth...all in the next 2-3 years! You will support us in driving the growth of our product, team, and company through each chapter as we go from ‘start-up’ to ‘scale-up’. You’ll be joining us at an incredibly exciting time, just as things are starting to take off!

We’re a Series A company having raised $25m from Accel, Point Nine, First Round, and 50+ renowned founders and industry experts. We’ve built an incredible & passionate team — every member was a top performer at their previous business - and our CEO, CCO & CFO went on a similar journey with Tessian, going from $0-30m ARR / $8-$500m valuation, and from pre-seed to Series C (Sequoia, Accel, etc.).

We’ve spent the past 18 months building & deploying our platform to many of the greatest tech companies out there (Lookout, McAfee, Onfido, Typeform, Proofpoint, etc.), all whilst managing to stay lean & operate efficiently. Now we’re ready to scale. We are looking for the best software engineers out there to help make Omnea one of Europe’s leading tech businesses: come build with us!

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. We’re 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 (eg Java) this likely isn’t a fit for you.

Please note: we’re only able to provide visas for Senior+ (L3 & higher) candidates. This is the spec for our L2 role and so applicants requiring visas will be automatically rejected. You can find our senior spec here, if you meet our senior criteria (usually 5+ years experience, already having held a senior role elsewhere).

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 a team of experienced full-stack product engineers who were all high performers at some of the best tech companies out there.
• Direct Product Impact. You will 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, making sure 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, Hasura 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 will 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 will work across the stack, covering everything from DevOps to styling. We expect each other to take initiative, be proactive in problem-solving, and continuously seek improvements.
• Continuous Delivery. We embrace continuous delivery to keep our systems agile, responsive and safe. You will be deploying small, incremental changes to production multiple times per day, ensuring a constant flow of improvements and rapid adaptation to any customer needs or technical challenges.
• Tackle Scalability Challenges. As we grow our customer base from tens to hundreds and expand into new product domains, you will help us scale our product, architecture and processes efficiently while maintaining performance and reliability.
• Collaboration & Autonomy. You will 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 together.
• 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.

About You

• You have a few years' experience with building 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 spearheaded the engineering of critical systems before, working with best-in-class tooling in AWS, IaaC, observability and quality assessments. You want to discover the best ways to bring this to an early-stage startup.
• You know what good can look like. You understand what it takes to build highly reliable & well architected products. You build with quality, observability & redundancy at the forefront.
• 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 ready to pick up new skills and build quickly.
• You’re someone who craves ownership. Maybe you find yourself gravitating towards the meatier engineering projects or you want to level up DevOPS or SRE game. If there’s an opportunity to work on something bigger, you’re keen to take it on.
• 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, and level up those around you.
• You’re comfortable when faced with ambiguity. You’re happy to tackle problems without a predefined clear definition or obvious solution, and are excited to have autonomy to make decisions as you go, 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.

A few things to note:

• 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.
• 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.
• 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.

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