Jumpstart is a startup hiring platform partnering with a small, curated group of ambitious VC-backed startups in the UK. Our job is not to sell you roles; it’s to make sure that when you do move, it’s into a place where you’ll actually get to build, learn, and have real impact.
About the role
You will join a Seed/Series A VC-backed startup as one of the first engineering hires, with significant ownership over product and technical direction. You’ll build and ship core product features end-to-end, work closely with founders and designers, and help define the engineering standards, architecture, and culture that future hires will inherit.
At our partner startups, you’ll be brought in as a high-agency engineer trusted to build real products, not just write code against predefined specs. You’ll work on core systems from day one and help shape the technical and product foundation of the company.
- Build and scale products used by thousands or millions of users.
- Own features end-to-end, from schema design to frontend.
- Make architectural decisions that define the product long-term.
- Collaborate directly with founders, designers, and product managers; no translation layers.
- Ship quickly, iterate relentlessly, and see immediate real-world impact.
What we’re looking for
- Strong across the stack and opinionated about building great products.
- Comfortable with modern frontend and backend tooling (e.g. React, TypeScript, Node).
- Product-minded; you care about outcomes, not just implementation.
- Autonomous, pragmatic, and excited by early-stage or fast-moving environments.
- Clear communicator who enjoys collaborating beyond engineering.
We care far more about your ability to reason, ship, and own problems than about any specific tech stack.
