Experience:
4+ years
*(strong hands-on academic experience may also be considered)*
We’re looking for a passionate
GNSS Navigation Engineer / Navigation Lead
to work on next-generation
LEO-PNT (Positioning, Navigation & Timing)
systems and help shape the future of satellite-based navigation.
? Key Responsibilities
• Design and develop
PVT (Position, Velocity, Time) estimation algorithms
• Work on pseudorange, Doppler and carrier-phase processing
• Develop navigation filtering and estimation pipelines
• Build correction models for ionospheric/tropospheric errors, clock bias, multipath and measurement bias
• Perform
GNSS & LEO-PNT system simulations and modeling
• Work on
PPP, Differential Corrections and Hybrid GNSS + LEO positioning
• Analyze GNSS robustness against
jamming, spoofing, interference and multipath
• Develop simulation and validation environments for navigation performance
• Evaluate accuracy, integrity,
availability, continuity and convergence
• Support software receiver, SDR and hardware-in-the-loop testing
• Collaborate with signal processing, hardware, mission design and GNSS teams
? Required Skills
✅ Strong knowledge of
Digital Communications & Signal Processing
✅ GNSS experience —
GPS / Galileo / NavIC / etc.
✅ Robust understanding of
PVT estimation, Doppler, pseudorange and navigation measurements
✅ Knowledge of navigation coordinate frames and timing systems
✅ Proficiency in
MATLAB / Python / C/C++
✅ Familiarity with
MATLAB/Simulink, GNU Radio
or similar simulation tools
⭐ Preferred
• GNSS/PNT signal processing experience
• Knowledge of
PPP / PPP-RTK / LEO-PNT
• Anti-jamming / anti-spoofing and interference mitigation
• FPGA/DSP implementation experience
• Software-defined receivers / SDR experience
• Hardware testing and system integration experience
