Responsibilities include, but are not limited to the following :

Derive requirements, conceptualize, define, design & prototype PNT solutions

Create, analyze and refine the required software for stationary timing, and positioning for motion platforms such as UAVs and UAS

Develop software using C in an RTOS environment to translate prototypes into optimized, production-quality code suitable for operational deployment

Perform hardware / software integration, debugging, and code optimization on target platforms

Interface with cross-functional teams and sites and customers to define and implement new features

Coordinate technical discussions and collaborate with platform and system architects to make design decisions

May act as technical lead and provide mentoring to other software engineers
