Our company is being built by exceptional engineers - people who find high-impact and technically challenging work engaging and exciting, and who consistently deliver outsized impact.

If you are motivated by our mission and if you want to be part of a growing team of outstanding people, then we want to hear from you.

Unlike most defence tech, design is a first-class citizen  accomplish our vision, we believe it's crucial our software is unmistakable in mission-critical scenarios, governed by careful design decisions and rigorous safeguarding along the way.

The work you’ll be doing here will be in entirely new and unexplored problem spaces.
