Job description

Position: Forward Deployed Engineer

Location: London or Amsterdam, 3 days a week in office

The Role:

We're looking for a technically sharp, product-minded engineer to help push the frontier of AI across Just Eat Takeaway. You'll work with some of our most ambitious internal teams and technology partners - helping them get the most out of advanced AI, and turning those learnings into durable improvements across our organisation.

This is a builder role. You'll dig into complex workflows, identify the gaps that matter, and translate them into concrete technical insights that shape how we build. If you're as comfortable debugging a live workflow as you are designing an evaluation framework or presenting findings to a non-technical audience, you'll fit right in.

Key Responsibilities:

• Work directly with internal teams and strategic partners to understand critical workflows, uncover failure modes, and identify the highest-impact opportunities for AI improvement.
• Prototype and iterate on prompts, agents, and workflow designs to understand system behaviour and unlock real value - not just theoretical improvements.
• Synthesise findings for our Product Engineering and Platform teams, turning real usage patterns into clear, reproducible evaluations, benchmarks, and technical artefacts that improve product and platform quality.
• Build repeatable tools, patterns, and evaluation approaches that raise the quality bar across multiple use cases - not just one-off fixes.
• Operate with strong judgment in ambiguous environments, balancing immediate technical problem-solving with longer-term systemic improvement.
• Build relationships across our engineering and product communities, serving as a trusted technical partner to individuals and teams alike.

These are some of the key components to the position:

You’ll thrive here if you have strong software engineering and AI fundamentals - whether that’s from experience in a startup, or a product focused role in a larger org. Software engineer, ML engineer, data scientist, or equivalent. Product Managers, BAs or Technical Programme Managers keen to return to a builder role. A track record of shipping production systems end-to-end is a strong plus.

What will you bring to the team?

• Experience building AI applications, agents, or evaluation systems, with the ability to reason clearly about model behaviour in complex workflows.
• Comfort working directly with highly experienced functional SMEs and translating their challenges into concrete technical signals.
• Production experience with AWS at scale, using services like ECS, Lambda, DynamoDB, SQS
• Fluency moving between prototyping, debugging, evaluation design, and cross-functional collaboration - sometimes all in the same day.
• Working across every layer of the stack - Able to switch between configuring a connector in an admin panel to prompting an agent to contribute code back to our underlying platform.
• Clear communication across technical and non-technical audiences - you can explain what you found and why it matters.
• High agency and a strong product sense, with a bias toward building things that last rather than one-off fixes.
• AI First problem solving, deeply experienced with AI tools to drive fast solution creation, able to balance model usage to maximise ROI, everything from coding to design and more.
• Bonus: Familiarity with complex market place businesses. Experience as an early-stage startup engineer or in a previous FDE style role. None of these is a dealbreaker - we're more interested in how you think than what you've already shipped.
• AWS Solutions Architect - Associate (Nice to have)
