Full Stack Engineer at VC backed startup

About the Role
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.
