Just someone who enjoys talking to engineers on a daily basis | Associate Director @ Linux Recruit

If you’re looking for a comfortable 9 to 5, something well established, structured, and where you’re told exactly what to do, this won’t be for you. But if you want to build something extraordinary from the ground up and have a direct hand in shaping a company that’s scaling at breathtaking speed, keep reading.

This is your chance to join an early stage AI startup that’s redefining how innovation is discovered, protected, and accelerated. The team is building systems that detect infringement, streamline R&D, and empower creators to move faster. It’s a true greenfield opportunity, no legacy code, no bureaucracy, just the freedom to solve challenging technical problems with impact.

The founding team comes from some of the world’s most respected technology companies and is backed by tier‑one investors and industry leaders who know how to build billion‑dollar businesses. The company’s trajectory is ambitious, from zero to seven figures in recurring revenue within its first year and plus over £20million in funding already.

As a Software Engineer, you’ll join a small, high calibre team where ownership is everything. You’ll work primarily on the backend, integrating with LLMs, and collaborating directly with the founders to design, ship, and iterate products. You’ll speak with customers, think critically from their perspective, and see your work have an immediate, visible impact. The team operates in one‑week sprints, moving at an intensity few companies can match.

This isn’t a clock‑in, clock‑out culture, it’s built for those who thrive in fast‑moving, high‑ownership environments. This company has an in‑office culture mainly because there’s nothing quite like building the next tech unicorn, together, in the same room, ask the big players.

What you’ll need to succeed:
  • Strong experience building production quality software (Type Script, React or Python)
  • Curiosity and adaptabilit
    y: you learn new technologies quickly and apply them effectively
  • Hunger and drive: you’re comfortable working in ambiguous, fast paced environments
  • Ownership mentality: you take full responsibility for solving problems, not waiting for instructions

In return, you’ll receive a highly competitive base salary, meaningful stock options, and the opportunity to join right before takeoff. That’s the real reason people join startups, the ownership, the impact, and the upside. Those options could change your life, your home, your car, your freedom whatever drives you.
