Ocado GroupExternal listing

Sofia, Bulgaria · On site · Full time · Posted 15 Jul 2026

About the role

<p>The&nbsp;<strong>Mobile Fulfilment Systems</strong> department at <strong>Ocado</strong> 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.</p> <p>Within this department, the <strong>Chuck Norris team</strong> 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 <strong>Chuck Autonomous Mobile Robot</strong>.</p> <p>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.</p> <p><strong>About the Role</strong></p> <p>This is a senior engineering role with a strong <strong>AI focus</strong>. 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.</p> <p><strong>About You</strong></p> <p><strong>Your engineering foundation</strong></p> <ul> <li>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.</li> <li>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.</li> <li>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.</li> </ul> <p><strong>Your AI edge</strong></p> <ul> <li>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.</li> <li>Hands-on experience integrating LLMs into real software, with a working command of feedback loops, guardrails, and validation as the path to quality.</li> <li>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.</li> <li>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.</li> </ul> <p><strong>What we offer</strong></p> <ul> <li>Hybrid office attendance policy that sees you onsite 60%/40% of your time (this depends on the position and whether it's within SCC or tech)</li> <li>30 days of “Work from anywhere” program</li> <li>25 days of annual leave</li> <li>100 EUR monthly for food vouchers</li> <li>50 EUR social allowance paid with your monthly salary</li> <li>Enhanced maternity and paternity leave policy</li> <li>Medical plan including health &amp; dental coverage</li> <li>Life and disability insurance</li> <li>Employee assistance program</li> <li>Partial Multisport Card Coverage (this is something we don't usually mention, but it is one of our benefits)</li> </ul> <p>We also have regular divisional socials, sports clubs not to mention the Ocado Technology Academy for a packed schedule of courses, conferences and events.
