About the role
Hadean is a deep-tech company building cutting-edge distributed computing technology that powers scalable, secure, and interoperable digital environments. Our platform enables real-time simulation and training, mission rehearsal, command & control and digital twin capabilities - transforming the way defence, government agencies and enterprises plan, train, and make decisions.
We work at the forefront of defence innovation, collaborating with global partners to deliver next-generation capabilities that unlock operational advantage.
The Team
dominAI is a close-knit team of highly technical, deeply collaborative engineers — each bringing genuine specialism to a shared mission. We move fast, hold each other to a high standard, and take real pride in what we ship. We work in sprints, building MVPs that are regularly taken out to industry events, integration hackathons, and live demonstrators. There's no waiting months to see your work matter - the feedback loop between building and showing is tight, and it shapes what we build next. We're also a team that invests in itself: continuous learning, honest retrospectives, and a genuine culture of craft are part of how we operate.
This is a new product for Hadean. We're building it quickly and building it right - and the people who join now will shape its direction.
The Role
As a Software Engineer in the dominAI team, you will build across the full stack of our next-generation command and control platform. This is a system that enables commanders to plan and assess targeting outcomes in minutes rather than hours by embedding AI and large-scale simulation directly into the C2 workflow. You will work within a cross-functional team of AI, simulation, and infrastructure specialists, contributing to backend services that integrate with diverse simulation and analysis pipelines and to the web interfaces through which commanders and staff interact with those capabilities. You will own features end to end, supported by senior engineers who invest in your growth through mentorship, pairing and code review. As your judgement across the stack develops, so will the scope you take on.
