Software Engineer, Platform

Employment Type: FullTime

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.

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.

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.

• Hands-on Datadog experience.

• Experience building internal developer platforms or tools adopted org-wide.

• Open-source contributions to infrastructure or developer tooling projects.
