Just Eat Takeaway.com; Knaphill; On-site; GBP 90,000 - 120,000; Full time

Job summary

Just Eat Takeaway.com is seeking a permanent senior Golang engineer to elevate our integration platform that connects Grocery Partners with the Just Eat Takeaway marketplace. You will build in Golang, set the technical direction, and mentor mid-level and junior engineers while keeping production services on AWS and Kubernetes.

Key skills include event-driven distributed systems, on-call incident response, TDD, and strong communication.

Qualifications

• Strong experience with Golang.
• Experience with event-driven distributed systems: HTTP/REST services, async messaging (Kafka, SQS, SNS, Pub/Sub or RabbitMQ), eventual consistency, idempotency, retries and dead-letter handling.
• A track record of running your own services in production on AWS: on-call, incident response and observability.
• Experience with Test-Driven Development (TDD).
• Ownership beyond your own tickets: you take problems end to end and improve how the team works.
• Mentoring shown by what you've already done, such as mentoring engineers, running learning sessions or writing docs others used.
• A great communicator: you're comfortable explaining technical ideas to non-technical people, and "working out loud" (WOL'ing) so others can follow your thinking.
• AI-assisted development: the team uses tools like Claude Code and Kiro every day. We want engineers who use AI to move faster while keeping their own engineering judgement, and who can explain and defend any code they ship.
• Pair programming experience
• Technical leadership, such as leading a project or owning an architecture decision, would be a plus
• Experience with Kubernetes or another container platform would be a plus

Responsibilities

• Build new features in our core language, Golang.
• Make key architectural decisions and set the technical direction for the platform.
• Support product and delivery teams.
• Mentor mid level and junior engineers, and shape how the team builds.
