Full Stack Engineer at VC backed startup

Company: Jumpstart
Apply for the Full Stack Engineer at VC backed startup
Location: London
Job Description:

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 design, and help define the engineering standards, architecture, and culture that future hires will inherit.

  • Build and scale products used by thousands or millions of users
  • Own features end-to-end, from schema design to front‑end implementation
  • Make architectural decisions that define the product long‑term
  • Collaborate directly with founders, designers, and PMs – no translation layer
  • Ship quickly, iterate relentlessly, and see immediate real‑world impact

What we’re looking for

We’re looking for engineers who are strong across the stack and opinionated about building great products.

  • Comfortable with modern front‑end and back‑end tooling (e.g., React, TypeScript, Node)
  • Product‑mindful; you care about outcomes, not just implementation details
  • Autonomous, pragmatic, and excited by early‑stage or fast‑moving environments
  • Clear communicators who enjoy collaborating beyond engineering

We care far more about your ability to reason, ship, and own problems than about any specific tech stack.
