Frontend Engineer
Role Summary
Join Omnea as a Frontend Engineer in London, where you'll own the front-end architecture and design system for a fast-growing tech startup backed by prominent investors.
About the Organisation
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.
The opportunity is massive. Every enterprise on the planet has this problem and nobody has solved it. 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 & the Sunday Times' #1 Best Medium Sized Tech Company To Work for.
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.
- You're deep in React. You've built complex, production React applications and you understand the framework properly, not just the API surface. Rendering behaviour, state, performance, and where things break at scale.
- You've owned front-end infrastructure. Rendering strategies, build tooling, bundle performance, and the architectural decisions underneath a large application.
- You've built or owned a design system. Not just consumed one. You've made the calls on component APIs, driven adoption across teams, and dealt with the messy reality of migration and versioning.
- You have taste. You care how things look and feel, you notice when something is only 90% right, and you can hold a genuine conversation with designers rather than just implementing tickets.
- You know CSS deeply. Layout, styling architecture, and building interfaces that hold up across breakpoints, themes, and edge cases. You treat accessibility and motion as part of the craft rather than a checklist at the end.
- You're a strong engineer first. Your depth and your interest sit in the front end, and that's the point of this role. But you're fluent in TypeScript generally and comfortable working beyond the browser when a problem calls for it.
- You're motivated by impact. You care about what your work actually achieves, not just how it's built. You thrive with the autonomy to make meaningful decisions and take real ownership of outcomes.
- You're a team builder. You're excited by maximising team performance, whether that means learning from others or taking the time to explain, give feedback, and level up those around you.
- You're comfortable with ambiguity. This role is new. Its shape will be partly yours to define, and you're happy tackling problems without a predefined solution, backed by an experienced team.
Minimum Requirements
We're looking for a Frontend Engineer to own the front end at Omnea.
Our design system is growing fast, our front-end architecture is becoming more complex, and right now ownership of these things is distributed. You'd be the person who takes this to the next level.
You'll work across every product team. You'll own the design system, own the front-end architecture, and set the standard for how we build interfaces. We're a tight-knit group of ambitious builders who hold the bar high. It took over 10,000 interviews to hire our first 50 Omneans. Over the next year, our engineering team will double in size, our enterprise customer base will grow from ~180 to 300+, and revenue will triple. The front end has to scale with it.
This is a craft role with real leverage. Almost every engineer at Omnea ships front end. What you build determines how well they do it.
Procurement is a harder interface problem than it sounds. Approval workflows that branch and re-route, dense tables people live in all day, intake forms that adapt to what someone is buying. Getting this right is the difference between software people tolerate and software people actually like using.
- You've worked at design-led companies or somewhere with a genuinely high bar for interface quality.
- You've performed exceptionally at something else, be it academics, sport, or work. You've gone above and beyond the norm.
- You love engineering. It's more than a job. You've contributed to open source or worked on side projects just because you enjoy it.
