Staff/Senior Software Engineer - Hydris - Golang (d/f/m)

New Challenge About Us Project Q GmbH ("Q") is a Germany-based DefenseTech company with offices in Berlin and Munich. We network market-available sensors, effectors, or situational awareness systems into a tactical IoT backbone that reliably provides armed forces and security agencies with cross-domain information superiority — automated, scalable, and cost-efficient. Our solutions integrate seamlessly into existing defense and maritime infrastructures, delivering fast data fusion and AI-enhanced analytics for robust situational awareness in dynamic environments. We build platform-agnostic systems that enable real interoperability across domains. As a Staff Software Engineer, you'll directly impact the technical direction of our orchestration products – Hydris – the coordination engine for sensors and mission systems, and the interoperability API that underpins it. You'll work at the layer where heterogeneous real-world systems like radars, AIS receivers, LoRa mesh radios, satellite feeds, and C2 platforms become a single coherent picture.
