Platform Engineer

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 https://sifted.eu/leaderboards/sifted-future-50-2025 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 https://www.linkedin.com/in/ben-freeman-a8542166/, Abs https://www.linkedin.com/in/abhirukt/, Sabrina https://www.linkedin.com/in/scastiglione/, and Rebe https://www.linkedin.com/in/rebecatristan/.

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.
