- Own the full software development life cycle including requirements analysis, design, implementation, integration, and test.
- Partner with electrical engineers, mathematicians, computer scientists, and analysts to develop hardware / software interfaces and shape overall system performance.
- Author software test procedures, programs, and supporting technical documentation.
- Influence engineering practices, processes, and approaches across the organization.
Why this opportunity
You will work alongside a deeply technical, mission-focused team building cutting edge signal processing and geolocation systems.
