The posting

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 You

Your 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.
  • Bonus: familiarity with our environment (Kubernetes, GCP/AWS, Pub/Sub, PostgreSQL) and the modern AI stack - RAG and vector databases, orchestration frameworks (LangGraph, LangChain, LlamaIndex, Strands SDK, n8n), and the MCP / A2A / CLI agent landscape.

What we offer

  • Hybrid office attendance policy that sees you onsite 60%/40% of your time
  • 30 days of “Work from anywhere” program
  • 25 days of annual leave
  • 100 EUR monthly for food vouchers
  • 50 EUR social allowance paid with your monthly salary
  • Enhanced maternity and paternity leave policy
  • Medical plan including health & dental coverage
  • Life and disability insurance
  • Employee assistance program
  • Partial Multisport Card Coverage (this is something we don't usually mention, but it is one of our benefits)

We also have regular divisional socials, sports clubs not to mention the Ocado Technology Academy for a packed schedule of courses, conferences and events. If you think you have what it takes to make a difference, please submit your application below.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
