Frontend Engineer

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 frontend engineering hires, with significant ownership over the user-facing product and frontend architecture. You’ll work closely with founders, design, and product to turn early ideas into polished, scalable experiences, and help define the frontend standards, tooling, and culture that future hires will inherit.

What you’ll work on

Most frontend roles today aren’t really frontend roles. They’re ticket queues.

This one is different.

At our partner startups, you’ll be trusted as a high‑agency frontend engineer to build real products, not just implement designs. You’ll own core user experiences end‑to‑end and help shape how the product feels, performs, and evolves.

You will:

• Build and ship high-quality user interfaces used by thousands or millions of users
• Own features end‑to‑end, from interaction design to production‑ready code
• Shape frontend architecture, patterns, and performance from day oneWork directly with founders, designers, and PMs. No layers, no handoffs
• 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 frontend and backend tooling (e.g. React, TypeScript, Node)
• Product‑minded; you care about outcomes, not just implementations
• 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.

How our process works

01: Apply to Jumpstart

Apply in ~2 minutes HERE with your CV and anything you’ve built (GitHub, side projects, startups). If it looks like a fit, you’ll have a short call with our in‑house CTO. No live coding. No take‑homes. Just a chat to understand how you think as an engineer.

02: Join the platform

Once accepted, you’ll create a profile and get access to a curated set of early‑stage engineering roles, all from vetted VC‑backed startups.

03: CTOs pitch to you

We share your profile with 100+ CTOs in our network. Strong candidates often receive multiple direct messages from CTOs pitching their role, team, and product.

04: Get support landing your role

You’ll get access to a hotline with our in‑house CTO Patrick, with 1‑1 support on everything from initial interview support, to case study feedback, all the way through to final offer negotiation & support.

What makes this different

• Unparalleled access: CTOs pitch to you and your profile is shared with 100s of startups
• Curated matching: We filter hard on both sides
• Signal over noise: No mass applications or recruiter spam
• Real ownership: Roles where engineers shape the product and culture
• UK-focused: Leading UK startups, remote‑friendly or London‑based

What you get

• Access to roles that aren’t publicly advertised
• Optional 1:1 prep with experienced engineers, founders, or CTOs
• A long‑term community of builders, potential collaborators & co‑founders
