Go Backend Engineer for AI-Driven Agent Support

Deliveroo; West of England; On-site; GBP 65,000 - 95,000; Full time

Job summary

Deliveroo is expanding its Agent Experience team, building AI-powered backend services for Astra’s agent-assist features. You’ll own feature-level work from requirements to tested code, with exposure to LLM integration and high-volume, latency-sensitive infrastructure.

We value strong Go backend fundamentals, the ability to ship production services, and clear RFC-driven decision making. Collaborate with senior engineers and cross-functional teams to deliver reliable systems in a fast-moving

Qualifications

• Solid backend engineering fundamentals in Go, with experience shipping and maintaining production services.
• Exposure to LLM-powered features in production (prompt/completion integration, provider APIs) will ramp you up.
• Ability to independently own feature-level work: from a written requirement to tested, shipped code.
• Comfort working in a domain with multiple chat/support surfaces — trace issues to the right service.
• Clear technical writing (RFCs for feature-level decisions) and good judgment about when to ask for help.

Responsibilities

• Build and maintain backend services for agent-assist features on Astra, taking on feature-level work with increasing independence.
• Translate requirements into working code: design the feature-level approach, write an RFC when the change affects other engineers, and implement it end-to-end.
• Integrate with LLM-backed features — wiring up prompt/completion calls, handling provider responses, and validating output quality and correctness.
• Break down assigned project work into tasks, provide accurate estimates, and keep your own progress and dependencies on track.
• Apply AI tooling thoughtfully to your own workflow (coding, testing, review) and critically evaluate its output rather than taking it at face value.
• Participate in code review — both giving and receiving — to help the team hold a high bar for correctness, quality, and standards compliance.
• Collaborate with senior engineers and partner teams to clarify problem definitions, unblock yourself, and flag risks or blockers early.
