The PositionWe are seeking a Senior VHDL Digital Communications Engineer to join our team and contribute to the design, development, and testing of both hardware and FPGA-based digital signal processing systems. You will work on everything from high-speed analog/digital circuits to advanced VHDL implementations for space and ground systems, helping to build our constellation of satellites and next-gen receiver technologies. This role offers significant upward mobility.
We'll Expect You To...- Design and develop reliable FPGA-based digital signal processing solutions for our GNSS architecture
- Implement CDMA and DSSS receivers using VHDL on FPGA platforms
- Develop and integrate modem algorithms supporting BPSK through 8PSK modulation
- Apply advanced FEC techniques (e.g., LDPC), timing recovery (Costas loops), and digital pre-distortion (DPD) for high-Doppler LEO environments
- Interface with high-speed ADCs/DACs, manage clock domains, and integrate with analog RF front ends
- Evaluate and improve system performance under channel impairments like multipath, Doppler, and fading
- Support product development, infrastructure commissioning, anomaly investigation, and operations automation
- Work closely with cross-functional teams including RF, systems, and verification engineers
- Ensure quality standards through rigorous testing and validation procedures
You'll Need to Have...- B.S. in Electrical Engineering, Computer Engineering, or related field (M.S. preferred)
- 5+ years of experience in digital communications and VHDL development for embedded or FPGA-based systems
- 3+ years of experience in electrical engineering for GNSS, space, or wireless communications applications
- Proficiency with SoC and FPGA toolchains, mixed-signal design, and software-defined radios
- Strong understanding of RF systems, signal impairments, and satellite communications
- Excellent communication, collaboration, and documentation skills
- U.S. Citizen (required)
- Ability to travel up to 10%
We'd Like to See...- Experience implementing hardware-in-the-loop, simulation, and field testing
- Experience with GNU Radio and Software Defined Radios (SDRs)
- Experience with automated test frameworks for BER and EVM measurements
- Adaptive filtering and interference mitigation experience
- Prior experience working in a startup environment
- Active U.S. security clearance
Cultural Fit- Thrive in a startup environment
- Positive, team-first communicator
- Willing to roll up sleeves and work cross-functionally
- Strategic thinker with tactical execution skills
Compensation and BenefitsThe selected candidate will be competitively compensated with salary, equity (stock options), and a full benefits package.
