Backend Engineer (Go) for AI-Powered Agent Tools

Deliveroo; Greater London; On-site; GBP 60,000 - 90,000; Full time

Job summary

Deliveroo is seeking a backend engineer to own and enhance agent-assist features within Astra, focusing on Go-based services and integration with LLM-powered capabilities. You’ll translate requirements into code, implement end-to-end features, and participate in design reviews.

You’ll collaborate with senior engineers to clarify problems, estimate work, and ensure quality across production services in a fast-moving ecosystem.

Qualifications

• Solid backend engineering fundamentals in Go and production readiness.
• Experience shipping and maintaining production services.
• Ability to own feature-level work from requirement to shipped code.
• Familiarity with multi-surface domains and tracing issues to services.
• Clear technical writing and judgment on when to escalate.

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.
