Duties & Responsibilities:
VIAVI Solutions is hiring an experienced embedded Software Engineer to join the software development team designing the next generation and state-of-the-art products and technologies in resilient alternative Positioning, Navigation, and Timing (aPNT) receiver technologies. Supported technologies include: implementing receivers with the latest emerging Satellite radio signals, timing synchronization, algorithms for geo-location and navigation INS and Kalman filter integration for un-aided navigation, driver development for embedded GNSS receiver technologies. Systems will be fielded quickly for critical infrastructure protection, UAV timing- and positioning-, anti-jamming, and anti-spoofing applications. Work on the next generation, leading-edge Critical Infrastructure, government and Commercial Timing and Frequency solutions.
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
Pre-Requisites / Skills / Experience Requirements:
