Software Engineer, Engineering Acceleration at Omnea in London

Job description

Our Mission: 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. Find out more about the team and life at Omnea here. What We're Looking For We're looking for software engineers to join Engineering Acceleration, one of the teams in Omnea's Platform Engineering department, building the tools and infrastructure that help Omnea's engineers develop, test and ship software. Engineering Acceleration develops and operates the systems that support AI-assisted software development: agent tooling, context management, development environments and automated validation. You'll work across application code and infrastructure, improving existing systems and building new capabilities. You'll likely come from product or backend engineering, though developer tooling experience is a plus. What matters is strong software engineering ability, practical infrastructure experience and an interest in making other engineers more effective. What You'll Do • Build systems for AI-native software engineering. Develop the tooling and infrastructure that enable engineers to delegate substantial engineering work to agents, spanning investigation, implementation, testing and code review. Improve the context, execution environments and feedback available to agents so they can complete increasingly complex tasks reliably. • Improve development and testing environments. Develop the infrastructure that allows engineers and agents to reproduce problems, run applications and verify changes. Improve development environments, previews and automated validation. • Evaluate quality and impact. Build evaluations for agent behaviour and test changes to context, tools and configuration against representative engineering tasks. Measure the effect on correctness, review effort, reliability and cost before wider rollout. • Identify and address engineering bottlenecks. Work with engineers across Omnea to identify friction in development, testing and delivery. Prioritise improvements based on their impact on engineering productivity and software quality, and measure the results. • Lead tooling selection and adoption. Assess emerging tools and make build-versus-buy decisions based on capability, integration effort and long-term maintenance. Spearhead the selection and rollout of an agentic development platform (ADP), giving engineers a single interface for tooling and agent management. • Own systems through delivery and operation. Take responsibility for technical design, implementation, deployment and ongoing operation. Build for reliability and maintainability, with appropriate observability, access controls and recovery mechanisms. What Can You Expect? • Join the team early. Help shape and invent how engineers and agents design, build and verify software at Omnea. You'll be an integral
