Senior GNSS Receiver Engineer
About The Position
Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth. With Pulsar – the world’s most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection. We're seeking a GNSS Receiver Engineer to join our Navigation Software team, where you'll work at the intersection of signal design and receiver implementation. You'll be instrumental in developing and validating the receiver architectures that process our novel LEO PNT signals from acquisition and tracking through measurement generation. This role sits at the heart of our system: you'll help shape how our signal-in-space design translates into real receiver performance, working directly with our Interface Control Documents (ICD) to ensure our modulation schemes, navigation message formats, and signal structures are implementable and optimized for precision.
Requirements
- MS or PhD in Electrical Engineering, Aerospace Engineering, or related field
- 3+ years of experience with GNSS receiver development or signal processing
- Strong C++ programming skills with experience in real-time or embedded signal processing
- Hands-on experience with software-defined radio platforms (GNSS-SDR, GNU Radio, or similar)
- Deep understanding of GNSS signal structures: spreading codes, modulation schemes, correlation, and tracking loops
- Experience with carrier and code tracking loop design (DLL, PLL, FLL)
- Familiarity with measurement generation—pseudorange, carrier phase, Doppler
Nice To Haves
- Experience with LEO satellite signals or high-Doppler tracking scenarios
- Familiarity with navigation message decoding and frame synchronization
- Exposure to signal authentication or advanced modulation schemes (BOC, CSK, etc.)
- Experience translating ICDs into receiver implementations
Responsibilities
- Developing and optimizing acquisition and tracking algorithms for our LEO PNT signals
- Implementing and testing receiver signal processing chains using our GNSS-SDR-based verification platform
- Analyzing signal designs and data modulation schemes, evaluating tradeoffs between receiver complexity and performance
- Generating and validating pseudorange and carrier phase measurements from signals in space
- Contributing to ICD development, ensuring signal specifications are grounded in practical receiver implementation
- Characterizing receiver performance through simulation and live signal testing with software-defined radio (SDR) hardware
