## Description

Reax is hiring a Staff Software Systems Engineer to own the software systems that connect embedded flight software, ground applications, human-machine interfaces, and supporting test infrastructure. This role exists to turn COTS applications, custom software, and evolving system requirements into reliable, maintainable software that works under real operational constraints: compute limits, latency, usability, regulatory expectations, integration risk, and compressed timelines. The timeline will shape the scope as much as the technical specification, so this person must be able to make disciplined tradeoffs without producing fragile systems or poor user interfaces.
This person will be expected to define architectures, select tools and components, write software, integrate with hardware, support test operations, evaluate compliance paths, and make explicit trades against schedule, cost, reliability, maintainability, usability, and performance. The role requires a multidisciplinary engineer who can move between low-level embedded concerns and system-level operational outcomes without losing ownership of either., The engineer is the responsible engineer for the software subsystem and is expected to act as both technical owner and product owner for that scope. This includes development, integration, and test of embedded flight software, ground software, human-machine interfaces, and supporting software infrastructure. The role does not initially include direct reports but requires coordination with other engineers across the vehicle as well as management of vendors and subcontractors.
The position combines subsystem technical ownership with programmatic responsibility. The engineer is expected to develop the subsystem in a scrappy and iterative manner while maintaining the level of technical clarity, analytical rigor, and professionalism required to support internal decision-making and external customer confidence.
