Senior Backend Engineer

The Mobile Fulfilment Systems department at Ocado is at the forefront of developing cutting-edge automation solutions for both in-store and warehouse online order fulfilment. We leverage distributed backend systems, intuitive mobile applications, and advanced autonomous mobile robots to enable fast, scalable, and cost-effective order collection.

Within this department, the Chuck Norris team is dedicated to building the software systems powering our Mobile Robotics products. Our scope spans mobile apps, backend microservices, workflow orchestration, integration APIs, and cloud-native components. All these drive the success of our flagship Chuck Autonomous Mobile Robot.

This role is central to shaping the architecture, scalability, and reliability of Ocado's cloud-based backend systems for mobile robotics. Your contributions will directly influence the efficiency and intelligence of our autonomous robot fleet in real-world operations.

About the Role

This is a senior engineering role with a strong AI focus. You'll do the full range of engineering work - designing systems, building features, keeping production healthy - with agentic AI at the centre of how you build. Working on OMRS, the platform that runs thousands of robots across 120+ live sites, you'll use AI to ship functionality dramatically faster and to make a business-critical system measurably more stable. Just as important, you'll discover the agentic workflows that actually work on a system this size and turn them into how the whole team builds.

About YouYour engineering foundation

• Technically senior, with deep command of at least one backend language (TypeScript, Go, Java, C++, Python, or similar) and experience building and operating cloud-native, distributed services.

• A strong instinct for system design: you can read an unfamiliar architecture, find where it breaks under load, and reason about trade-offs without getting lost in the weeds.

• Genuine ownership across greenfield and brownfield work - you drive things to completion, favour the simplest thing that delivers the value, and you're comfortable supporting what you build, including taking your turn in the on-call rota.

Your AI edge

• You use agentic AI tools every day and work at the leading edge of agentic software delivery. You follow the field closely and form your own well-reasoned views on models, tools, and workflows.

• Hands-on experience integrating LLMs into real software, with a working command of feedback loops, guardrails, and validation as the path to quality.

• You'd rather invent the right process than inherit one, and you turn what works into shared practice that levels up the people around you.
