Job description

What if your next role gave you the opportunity to shape the future of AI, rather than simply work within the boundaries of what already exists?

Imagine joining a company where AI is the entire focus, innovation is encouraged, and you have the freedom to turn ambitious ideas into real-world solutions. No outdated ways of working, no unnecessary limitations - just the opportunity to push boundaries and create technology that makes a genuine impact.

This is your chance to take ownership of exciting AI projects, influence technical strategy, and play a key role in shaping the direction of a growing business. You’ll work closely with clients to understand their challenges, identify opportunities for AI, and lead the development of intelligent solutions that transform how businesses operate.

You’ll be joining an ambitious start-up founded by experienced entrepreneurs who have already built a successful Data & AI business. With a strong foundation in the industry and a genuine passion for innovation, they’re creating an environment where experimentation is welcomed, ideas are valued, and you can make your mark from day one.

The role offers a unique blend of technical leadership, hands-on development, and client engagement. You’ll help bring the latest advancements in Large Language Models (LLMs), AI agents, and generative AI into production, delivering scalable, enterprise-grade solutions that solve meaningful business problems.

If you have strong Python skills, deep experience with LLMs, and a proven track record of designing and delivering production-ready AI solutions within enterprise environments, this could be exactly the opportunity you’ve been looking for.

Most importantly, you’ll be someone who enjoys exploring new technologies, challenging conventional thinking, and leading others to turn complex ideas into practical, high-impact AI products.
