Senior Software Engineer

If you're a senior engineer who wants to spend the next few years building alongside an Ex-Amazon AGI Applied Scientist on a platform powering the coffee shops and food chains you pass on every commute, this might be the role you've been waiting for.

The company is a PE-backed AI startup rebuilding back-of-house operations for hospitality. Pret a Manger, Blank Street, Dunkin' Donuts and Yolk Brands all run their back of house on this platform across 6 countries. The agent layer the team is building isn't a feature, it's the new architecture.

Who you'd be working with

• A founder who built and exited a real hospitality business before this one. Operator first.
• A Principal Engineer, Imperial-trained, 20+ years across startup and scale-up environments
• A Tech Lead with a startup-to-acquisition track record
• A Senior AI Engineer with deep production AI research credentials at Amazon, NeurIPS first author, US patent pending
• A Senior Data Engineer with 6+ years building production pipelines for 1000+ retail outlets
• A Head of Product with 12 years across banking, healthcare and AI-powered product

Around this senior core sits a small group of talented junior engineers shipping every week. Mentoring them is a meaningful part of this role.

What you'd actually do

You will ship product end-to-end using their stack (Node/NestJS, TypeScript, AWS, React), working with the Founder and Head of Product to decide what to build, not just how to build it.

You'll also partner closely with the Senior AI Engineer on getting AI work into production, and help the Tech Lead mentor the eager juniors, taking a lead how the team adopts AI in the way it builds, every day.

You'll likely:

• Have 5-10 years building production software, though we're flexible for the right person
• Ask why before how. You push back on specs that don't make sense for the customer.
• Be genuinely fluent with modern AI tooling. Claude Code, Cursor, agents, evals. Opinions earned by using it on real work.
• Be low-ego. The people around you learn from how you work, not just what you ship.
• Be comfortable in ambiguity. You take a customer problem and drive to a solution without waiting for a spec.

Above all, you think about the GM running the coffee shop at 6am as a real person, not a persona.
