Account Executive (Defense & Government)

At Hadean, we are building the next generation of defense technology. As a key player in the UK’s defense tech ecosystem, our world-leading software is trusted by defense organizations and militaries worldwide. We specialize in AI-powered digital wargaming and Command & Control systems that help users understand complexity, make better decisions, and operate at scale. Joining Hadean means working on technology with real-world impact, alongside a team that is driven to push the limits of what’s possible. The Role: We are hiring an Account Executive to grow Hadean’s presence across the US defense and government market. This is a hands-on sales role. You’ll be responsible for building your own pipeline, getting in front of the right people and working opportunities through to close. A big part of the job is knowing where we should be spending time and making sure we’re in the conversations that matter.

That includes building new relationships, developing existing ones, and making sure Hadean is showing up in the right programs and discussions. This is not a high-volume sales role. It requires a thoughtful approach to navigating complex organizations, understanding how decisions are made, and building credibility with the right people.

You may not have held a long tenure in senior sales roles, but you bring relevant defense experience, strong networks and the ability to open doors quickly. You thrive in ambiguity, are proactive in building pipeline and understand how to move opportunities from initial engagement through to conversion.
