Job description

Omnea is the agentic operating system for procurement.

Procurement touches every pound a business spends, yet requests still stall for weeks and approvals get lost in inboxes. Our AI-first platform changes that: our agents capture requests, route approvals, onboard suppliers, flag risk and track every renewal, while anyone in the business can ask a question and get an answer grounded in their own company’s data. Buying becomes painless for everyone, procurement gets a seat at the table, and our customers have saved more than 100,000 hours of manual work so far.

Companies like Spotify, PayPal, T. Rowe Price, JustEat, Adyen and S&P Global run procurement on Omnea. We're backed by $75M from Khosla Ventures, Insight Partners and Accel, and we've been named the UK's number one startup in the Startups 100, ranked 11th on Sifted's 2026 list of Europe's fastest-growing companies, and recognised as one of Fast Company's Most Innovative Companies.

Talent density matters more to us than almost anything else. We keep the bar high in every team, so everyone here has real ownership and real impact. Our team is full of former founders and operators who've scaled unicorns, and we're looking for people who want to do the best work of their careers alongside them.

Why We Need a Software Engineer (Platform) Now

Omnea deploys multiple times a day, serves enterprise customers who expect rock-solid reliability, and is scaling 10x. Our platform team owns the infrastructure, tooling, and developer experience that underpins all of this. We're adding a hands-on Platform Engineer to the team to improve our CI/CD, scale our serverless infrastructure, strengthen observability, and make every product engineer more effective.

What We're Looking For

We're hiring at both Level 3 (Senior) and Level 4 (Staff). For calibration, candidates typically bring 5+ years of platform engineering experience in high-growth, cloud-native SaaS environments, but we care more about impact than years.

You'll join an experienced platform team and contribute across the full stack, from infrastructure-as-code and deployment pipelines to developer tooling and occasionally product features.

What You'll Do

• Scale our infrastructure. Design and evolve our AWS serverless architecture (including Lambda, DynamoDB, Aurora, EventBridge) for 10x growth, multi-region HA, and data residency requirements.
• Own CI/CD and deployment. Build and improve our deployment pipelines (GitHub Actions), infrastructure-as-code (Pulumi), and release tooling so product teams can ship faster and safer.
• Own observability. Build out monitoring, alerting, and debugging across the stack using Datadog. When something breaks, we should know before our customers do.
• Improve developer experience. Build internal tooling, automate toil, and remove friction so engineers spend more time shipping product and less time fighting infrastructure.
• Code and build. Contribute production-ready TypeScript across infrastructure and product features; raise the bar through solid patterns, libraries, and reviews.

What Can You Expect?

• A strong team. You'll join a platform team of senior and staff engineers who set a high bar and will push you to do your best work.
• Modern, cloud-native stack. Everything serverless and IaC-driven (AWS, Pulumi, TypeScript end-to-end).
• Continuous delivery. We deploy multiple times a day. Your work determines how fast and safely the whole engineering org ships.
• Scalability challenges. As we 10x revenue, you'll evolve infrastructure for multi-region HA, data residency, and performance at scale.
• Customer impact. The reliability and speed you build is what lets us win and keep enterprise accounts.
• Massive ownership. You own problems end-to-end, from brainstorming through to production.
• Collaboration & autonomy. Plenty of heads-down technical work, but also close partnership with product engineers and engineering leadership.

About You

• Platform engineer & builder. You design reliable infrastructure and write clean production code (TypeScript or similar). You've built and maintained CI/CD pipelines, IaC, and developer tooling at scale.
• Cloud-native. Deep knowledge of AWS (Lambda, DynamoDB, EventBridge, IAM, networking) or equivalent cloud-native experience. You understand serverless and its trade-offs.
• Developer-first. You think about engineers as your customers. You automate toil, improve feedback loops, and care deeply about making other people productive.
• Commercially minded. You understand that infrastructure exists to serve the product and the business. You make trade-offs with that in mind.
• Bias for action. You iterate quickly, ship pragmatically, and automate everything.
• Culture carrier. You coach teammates, share knowledge freely, and keep calm when things break.

Nice-to-haves

• Experience with Pulumi or similar IaC frameworks.
• Experience building internal developer platforms or tools adopted org-wide.
• Open-source contributions to infrastructure or developer tooling projects.
