A rapidly growing defence tech startup is looking for a Senior Frontend Developer to join its high-calibre engineering team building next-generation software products used in real-world operational environments.

Founded by engineers from Palantir Technologies and backed by significant funding, the company is tackling technically complex problems with a strong emphasis on product quality, speed, and real-world impact.

This is a great opportunity for someone who enjoys working in a highly technical, fast-paced environment alongside genuinely strong engineers in a collaborative and low-ego team.

The Role

The team works primarily with:

  • Some Rust across parts of the platform

What They’re Looking For

  • Strong experience building frontend applications with React and TypeScript
  • Product-minded engineer who cares about usability and performance
  • Comfortable working closely with backend engineers, designers, and end users
  • Someone who enjoys ownership and moving quickly in a startup environment

Why Join?

  • Exceptional founding team with backgrounds from top-tier engineering companies
  • Well-funded business with ambitious long-term vision
  • High technical bar without a corporate environment
  • Strong in-person engineering culture with flexibility when needed
  • Opportunity to work on genuinely meaningful technology with real-world impact

If you enjoy working with smart people, solving hard technical problems, and building products that actually matter, this could be a very strong fit.
