Job description

A next-generation technology platform bringing together AI, data, software and complex real-world systems — and we're looking for a Principal Software Engineer to join the product team and help build it from the ground up.

This is a role for someone who wants serious ownership and still wants to be hands‑on.

You’ll be working directly on the product, making architectural decisions, solving difficult technical problems and helping shape how the platform is built as the company grows.

There’s no rigid roadmap or layers of management. You'll have the freedom to build, experiment, learn new technologies and move quickly — taking ideas from concept through to production.

You’ll work across the stack depending on what the problem requires, with plenty of scope to get involved in AI, data, backend systems and complex technical challenges.

We’re looking for someone who:

• Is a genuinely strong software engineer with experience operating at a senior/principal level
• Still loves being hands‑on and building
• Enjoys working in ambiguity and figuring things out from first principles
• Wants to have a meaningful influence on both the product and engineering direction

If you're an experienced engineer who wants to build something from an early stage rather than inherit someone else's architecture, this is worth a conversation.
