Hungry for a challenge?

That’s good, because at Just Eat Takeaway.com (JET) we believe everything is possible, or, as we say, everything is on the table. We are a leading global online food delivery marketplace. Our tech ecosystem connects millions of active customers with hundreds of thousands of connected partners in countries across the globe.

Our mission? To empower every food moment around the world, whether it’s through customer service, coding or couriers.

The Opportunity

We are looking for a proactive technical leader with a robust engineering foundation to drive our platform forward. As a Senior Engineer, you will bring deep expertise in system architecture from day one, guiding the team and shaping the technical vision required to build the high-volume POS and menu integrations that keep global brands running smoothly.

These are some of the key ingredients to the role:

As an engineer in the JET Connect team, you won’t just be writing code; you’ll be building the high-volume POS and menu integrations that keep global brands like McDonald’s, KFC, and Domino's running smoothly across 10+ countries.

In this role, you will have the opportunity to:

• Build, scale, and lead in Go: Architect, develop, and maintain robust, high-throughput microservices and complex features in Go.
• Drive system design and architecture: Lead the design and implementation of highly scalable solutions, shape the wider integration architecture, and confidently steer technical discussions.
• Champion system health: Define observability standards and lead our weekly signal channel reviews to identify, investigate, and proactively resolve production anomalies before they impact our partners.
• Elevate engineering standards: Mentor mid-level and junior engineers, lead collaborative debugging sessions for complex problems, and drive best practices across the engineering team.
• Collaborate across teams: Partner strategically with product and delivery teams to ensure our integrations roll out smoothly and reliably across international markets.

What will you bring to the table?

• Extensive Go experience: Substantial commercial experience (5+ years) writing clean, highly efficient, and testable code in Go.
• Architectural Event-Driven expertise: Deep expertise in architecting microservices and event-driven systems, with a mastery of the complexities involving eventual consistency and distributed architecture.
• An SRE mindset: You care deeply about system reliability after your code goes live, maintaining a strong focus on improving production services and incident response.
• AWS Cloud Services leadership: Advanced hands‑on experience designing and deploying scalable systems utilizing Amazon Web Services, including DynamoDB, SNS, SQS, and S3.
• AI-Assisted Development: You are highly comfortable leveraging AI coding assistants and LLMs to accelerate workflow, architect scaffolding, and debug complex, distributed issues.

At JET, this is on the menu:

Our teams forge connections internally and work with some of the best‑known brands on the planet, giving us truly international impact in a dynamic environment.

Fun, fast‑paced and supportive, the JET culture is about movement, growth and about celebrating every aspect of our JETers. Thanks to them we stay one step ahead of the competition.
