Position: Senior Forward Deployed Engineer

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.

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.
• 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—from coding to design and more.
• Bonus: Familiarity with complex marketplace 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.
