Job Description

- Define and own the end-to-end GNSS receiver software architecture, including acquisition, tracking, measurement engine, navigation, and positioning stack.
- Lead architectural decisions for low-power, high-performance GNSS chipsets, balancing performance, power, and silicon constraints.
- Translate product requirements into scalable, modular, and maintainable software architectures.
- Drive design trade-offs across algorithm complexity, hardware acceleration, and system constraints.
- Design and optimize advanced algorithms for GNSS acquisition and tracking (multi-constellation, multi-frequency), Positioning, navigation, and timing (PNT), Multipath mitigation and interference suppression, Snapshot and ultra-low-power GNSS techniques.
- Lead development of next-generation techniques such as Assisted GNSS (A-GNSS), Hybrid positioning (GNSS + Wi-Fi/Bluetooth/IMU), LEO-PNT and emerging navigation paradigms.
- Oversee implementation of GNSS algorithms in embedded C on RTOS / bare-metal systems, FPGA with focus on performance optimization, high-volume silicon deployment.
- Mentor and guide engineers, contractors in GNSS algorithms and embedded development. Set technical direction and promote engineering best practices, design standards and lead technical reviews, architecture discussions, decision-making processes.
- Cross-Functional collaboration with product management to shape feature roadmap and differentiation strategy. Present technical concepts and results to internal and external stakeholders, including leadership teams and customers.

Must Haves

- Master’s or PhD in Electrical Engineering, Signal Processing, or related field.
- 10+ years of experience in GNSS, wireless communication systems, or signal processing.
- Proven track record in GNSS system design and product development.
- Deep understanding of the GNSS signal processing chain, including acquisition, tracking, measurements,



and navigation.
- Strong expertise in embedded C/C++ development on RTOS or bare-metal platforms.
- MATLAB and Python for modelling and algorithm development.
- Experience with full chip/product lifecycle, from concept to production.
- Strong understanding of low-power embedded system design and optimization.
- Excellent communication, presentation, and technical leadership skills.

Nice to Have
