Sr. Software Integration Engineer

Q-CTRL•Huntsville, AL

49d

About The Position

The Sr. Software Integration Engineer will own deployment, configuration, and operational readiness of Q-CTRL’s navigation and quantum sensing software on unmanned aerial system (UAS) platforms. This hands-on, execution-focused role ensures software developed at headquarters is integrated, configured, tested, and operated on real platforms in laboratory and field environments. The engineer will work closely with systems and hardware engineers and headquarters software teams to bring up sensor and navigation stacks, verify operation before flight, and manage data flow for analysis. As the technology matures, the role will help establish deployment, testing, and release practices for hardware-in-the-loop and fielded systems. The position is part of a small US-based group supporting defense and aerospace programs within a growing global engineering team, at the intersection of software, hardware, and field operations. Intermittent domestic and international travel and regular communication across time zones are involved. Q-CTRL is a global quantum technology company that develops AI-powered quantum control infrastructure software for quantum computing and sensing. The company was founded in 2017 and has offices in Sydney, Los Angeles, San Francisco, Huntsville, Berlin, and Oxford. It emphasizes outcomes over hours and offers flexibility, equity potential, and competitive benefits.
