Full Stack Engineer (£100k + Equity) at yhangry - YC-backed private chef marketplace

Company Description: yhangry - YC-backed AI-native marketplace

Job Description:
Join yhangry as the third engineer to rebuild the UK's largest private chef marketplace from the ground up. You will architect a brand-new, AI-native platform for global expansion, moving beyond traditional workflows to integrate AI agents at the core. This is a founding-style role with direct impact on a scaling, revenue-generating business.

Why this role is remarkable:

• Founding-engineer level ownership as the 3rd technical hire, working directly with the Head of Engineering to shape architectural decisions and technical strategy.

• Backed by Y Combinator (W22) and featured on Dragons' Den, yhangry is already the UK's leader in its space with over 135,000 guests served.

• Opportunity to build a greenfield, AI-native platform using agentic workflows while solving complex marketplace challenges for a global rollout.

What you will do:

• Architect and build a brand-new AI-native platform using TypeScript, React, and Node, integrating AI agent workflows to automate complex marketplace operations.

• Deploy and manage scalable infrastructure on Kubernetes and maintain a robust data pipeline in Big Query to support data-driven business decisions.

• Partner directly with founders to translate customer needs into high-impact features, ensuring a world-class UX for both chefs and guests.

The ideal candidate:

• 3-7 years of full-stack experience with strong engineering foundations in TypeScript, React, and Node, plus familiarity with PHP or Go.

• Fully adopted AI-assisted development workflows to ship high-quality code faster without sacrificing a deep understanding of underlying system architecture.

• Proven track record in early-stage startups where you’ve demonstrated a product-minded approach, customer empathy, and the ability to solve problems independently.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
