Senior Backend Software Engineer – GenAI

The Company & Mission: Our client builds mission-critical software for military logistics and sustainment — a real-time command and control platform that keeps commanders informed even in degraded, contested environments. This is a real backend engineering role, not prompt engineering or AI tooling: the applied AI layer is built directly on top of the core platform, so we need a strong backend engineer who's developed genuine AI depth, not someone who's only wired APIs together.
