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

• Kalman filter integration and optimization
• Experience with version control systems (preferably Git)
• Experience using an Agile-based development process (preferably Scrum)
• Experience with project tracking software, preferably Atlassian tools (Jira, Confluence, Crucible)
• Knows intimate technical details of various GNSS systems, and is comfortable working with, and describing intimate details of Almanacs, Ephemerides, Rinex files, etc.
• Has recent practical or theoretical experience, and or training in Systems-Control-Theory.
• Good understanding of such concepts as over, under, and critically damping a control loop, FIR and IIR filtering in both SW and HW, and preferably has good experience with Kalman filtering as well as IMU aiding.
• Good understanding and can show proficiency when using simulation tools such as Matlab, as well as JTAG debuggers, and other analysis/simulation tools.

Optional Skills:

• Zero-IF and Heterodyne receiver implementations
• Particle filter implementation and optimization
• C++ and OO programming
• GNSS oscillator disciplining
• Navigation protocols such as NMEA, SCPI, and ICD-GPS-153
• Familiarity with FrameMaker documentation tools
• Vision-Based Navigation software and algorithmic design experience
