Xona Space Systems is a commercial space company building Pulsar, a Low Earth Orbit positioning, navigation, and timing (PNT) constellation that delivers centimeter-level positioning with enhanced signal power and anti-jamming capabilities.
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 Senior FPGA Engineer to lead the architectural specification and design of next-generation LEO PNT satellite systems. You will own the FPGA signal-processing pipeline from concept through flight-ready hardware, making critical trade-offs between mathematical idealization and physical hardware constraints. What you’ll Do - FPGA Architecture Ownership: Define and specify hardware architecture for high-dynamic acquisition, tracking, data decoding, and measurement processing pipelines. - DSP/FPGA Implementation: Lead fixed-point design, resource budgeting, and pipeline optimization to achieve performance and latency targets. - Technical Leadership: Establish RTL best practices and guide junior engineers through complex design cycles and hardware validation phases. - Cross-Functional Integration & HW/SW Partitioning: Define and optimize HW/SW partitioning in collaboration with SW teams; ensure efficient SW interfaces, seamless integration, robust system-level testing, and preservation of performance margins. - Performance & Risk Management: Drive timing closure, power optimization, and system-level performance verification; resolve complex cross-domain issues. - Vendor & IP Integration: Evaluate and integrate third-party IP cores, define acceptance criteria and compliance testing. - Verification Strategy: Establish robust verification frameworks, including simulation, emulation, and hardware validation. What you’ll bring: - PhD or MS/BS in EE/CE or related field, 7+ years of FPGA and DSP implementation experience. - Demonstrated ownership of complex FPGA signal-processing systems from architecture to hardware validation. - Deep expertise in fixed-point DSP implementation, pipelining, and resource optimization. - Strong experience with high-speed interfaces and complex FPGA subsystems. - Expert proficiency with FPGA toolchains, static timing analysis, and on-chip debugging. Preferred Qualifications: - Experience with satellite communications, esp. with GNSS receivers and in spread-spectrum systems. - Familiarity with processing of satellite-related measurements (code/carrier/Doppler/CN0, PRs, DRs). - Experience supporting HIL and over-the-air validation environments. Key Competencies: - Strong DSP foundation with practical FPGA implementation expertise. - Execution-focused mindset with emphasis on timing closure and hardware validation. - Clear technical communication and documentation. - Ability to collaborate across systems, RF, software, and navigation teams to deliver flight-ready FPGA solutions.
