Communications / DSP Engineer

The role

You will own end-to-end signal-chain system engineering for GEO backhaul and inter-satellite cross-links. This includes algorithm development, simulation, measurement engineering, and driving the architectural transition into FPGA-ready solutions.

What you will do

• Develop acquisition, tracking, data decoding, and measurement algorithms
• Drive architectural transition from mathematical models to fixed-point, optimized FPGA designs and verifications
• Build Python/C++ simulations and analyze performance
• Define HW/SW partitioning and system interfaces
• Optimize for FPGA resource utilization and timing constraints
• Specify measurement products and validate with Navigation team
• Lead vendor SOWs, acceptance tests, integration, and compliance reviews
• Document system architecture, simulations, trade studies, and verification results

Required qualifications

• MS or PhD in EE, CE, or related field
• 7+ years’ experience in digital communications, DSP, or satellite systems
• Strong mastery of synchronization, ranging, and spread-spectrum algorithm design
• Hands-on experience with FPGA-based signal processing and bit-true/fixed-point modeling
• Proficiency in Python, C/C++ for system modeling
• Prior experience in vendor technical leadership and cross-functional system integration

Nice to have

• GEO satellite backhaul or inter-satellite cross-link (ISL) experience
• Familiarity with GNSS navigation and spread-spectrum systems
• Knowledge of measurement integrity; experience with lab bring-up, test automation, and HIL/OTA testing
• Experience in ARM-based MPSoC systems (Cortex-A/R), with experience developing Embedded Linux (PetaLinux/Yocto) and device drivers specifically for Zynq UltraScale+ environments

Before you apply

• For U.S. Roles: applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual
• For U.K. Roles: requires Baseline Personnel Security Standard (BPSS) checks and eligibility to obtain UK Security Clearance (SC)
• For Canada Roles: must obtain and hold a security clearance at the reliability status level, and pass security assessment for the Canadian Controlled Goods Program (CGP) and ITAR
