Product Engineer (Full Stack)
Help shape the future of human–computer interaction by building fast, delightful, intelligent products.
We’re looking for a product-focused engineer who loves bringing ideas to life in a fast-moving, collaborative environment. You’ll work across the stack to design, build, and launch new features - the kind that make users go, “Whoa, that’s smart.”
This role is ideal for someone who thrives in early-stage environments, loves zero-to-one product building, and enjoys taking full ownership from concept to delivery.
What you’ll do
- Build new user-facing features end-to-end - from idea to production
- Experiment rapidly with prototypes and iterate based on user feedback
- Optimise for performance, scale, and reliability
- Collaborate closely with engineers, designers, and product leads to craft elegant, high-impact solutions
What you bring
- Strong experience building full-stack web applications
- Proficiency with TypeScript, Node.js, and React (experience with tools like Tailwind, Radix, or Framer Motion is a plus)
- Solid understanding of Postgres or similar relational databases
- Exposure to cloud infrastructure (AWS or similar; Terraform a plus)
- A genuine interest in AI and emerging technologies
Who you are
- A builder at heart - you love shipping
- Excited to work in-person from a central London office
- Energised by startup pace and ambiguity
- Pragmatic, kind, and ambitious in equal measure
- Driven by creating meaningful user experiences
Why this role
This is a chance to join an early team shaping the next generation of productivity tools. You’ll work hands-on with cutting-edge AI and help define both the product and the culture from the ground up.
My client offers above-market compensation (salary and equity) and relocation support for those joining us in London.
If this sounds like you, even if your background doesn’t tick every box we’d love to hear from you.
