Xona is building the next generation of satellite navigation — a high-performance, resilient alternative to GPS powered by a commercial constellation of low Earth orbit (LEO) satellites. We are on a mission to unlock a new era of autonomy, advanced mobility, and infrastructure resilience by delivering precise, secure, and robust positioning services to the world.
We’re not here to incrementally improve GNSS. We’re here to redefine it from the ground up .
We’re looking for a hands-on FPGA engineer to join our team and help design the next generation of space-based navigation payloads. You'll work on cutting-edge signal processing systems, secure hardware modules, and high-reliability designs that fly in orbit. If you thrive in a collaborative, fast-paced environment and are excited by the challenge of developing space-qualified digital systems, we want to hear from you.
What You'll Do
- Architect and implement RTL for Xilinx RFSoC and other space-qualified FPGAs.
- Design high-performance DSP and signal generation modules for navigation waveforms (e.g., PRN code generation, mixers, modulators).
- Develop secure hardware blocks (e.g., SHA-256, HMAC) for authentication and anti-spoofing.
- Build robust data pipelines to move and process signal streams in real-time.
- Design with space in mind: mitigate single event upsets (SEUs), implement fault detection/correction, and optimize for radiation-prone environments.
- Work closely with cross functional teams to bring up payload functionality on actual satellite hardware.
-
Simulate, verify, and test your designs rigorously—then see them fly.
- Bachelor’s or Master’s degree in Electrical or Computer Engineering (or similar).
- 3+ years of FPGA development experience using Verilog, VHDL, or SystemVerilog.
- Experience with HDL simulation and verification.
- Proven experience with AMD/Xilinx platforms—ideally RFSoC or Zynq Ultrascale+ - and their embedded PL+PS architectures.
- Solid background in DSP fundamentals and real-time signal processing in hardware.
- Strong grasp of on-chip dataflow, clock domain crossing, and AXI/AXI-Stream buses.
- Comfortable using Vivado, Riviera Pro, and Synplify.
- Proven track record of developing in a collaborative environment, including familiarity with git/gitlab and strong documentation discipline.
- Full-time, onsite in Burlingame, California (this role is not remote or hybrid)
-
To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States (i.e. Green Card holder), or other protected individual as defined by 8 U.S.C. 1324b(a)(3)
- Experience designing for space: SEU mitigation, TMR, scrubbing, or rad-hard flows.
- GNSS or navigation signal processing expertise (GPS, Galileo, etc.).
- Crypto hardware design (e.g., SHA-2, HMAC, AES) and experience with secure communication protocols.
- Familiarity with JESD204B/C, high-speed serial I/O, or RF front-end interfacing.
- Embedded software experience on ARM (e.g., for control/config of FPGA fabric).
- Python or TCL scripting for test automation and build flows.
- Knowledge of space qualification processes, radiation testing, or flight hardware integration, with preference for strong hardware-in-the-loop devops practices.
- C/C++ programming experience.
-
Experience with digital generation of high performance RF signals.
Range for base salary: $160,000 -$210,000
Senior Embedded Software Engineer
@ Embedd 
What we're looking for
At embedd.it, we power hardware-software integration in embedded devices. We turn fragmented semiconductor chip data into configurable digital twins, then deterministically generate code, tests, and documentation – making integration faster, cheaper, and resilient to supply chain shocks.
We’re looking for a true legend – someone with abstract thinking and deep expertise in low-level software development. You’ll build vendor-agnostic tooling for MCU and peripheral integration to solve hardware-software integration once and for all. We work at the intersection of embedded systems, code generation, compilers, and machine learning. It’s your chance to help redefine how low-level development is done.
Responsibilities
- Drive the architecture of the driver structures and system layout
- Define scalable patterns for cross-architectural integration across bare-metal, Zephyr, Linux, and other environments
- Deconstruct complex SoC device trees and translate hardware descriptions into structured internal models for automated reasoning
- Partner with the ML team to shape data and annotation models for AI-driven data-extraction tooling
Qualifications
- 5+ years of experience in embedded systems development, including bare-metal and RTOS-based systems
- Proficiency in C/C++
- Familiarity with firmware configuration, SoC bring-up, and system-level debugging
- Hands-on experience with code generation tools, or low-level compiler/decompiler/emulator technologies
- Strong background in embedded toolchains: compilers, linkers, debuggers, and build systems
- Python or scripting for automation and tooling is a plus
- Experience with functional-safety standards is a plus
Why embedd.it?
- Dynamic, venture-backed team of engineers challenging the status quo 🚀
- Work at the intersection of embedded systems, code generators, compilers, and ML 🤖
- Unusual challenges requiring out-of-the-box abstract thinking 🧠
- Competitive compensation: cash + equity 💰
- Remote work possible 🌍
About Us
embedd.it is a UK-based startup reinventing embedded development. Our platform transforms unstructured semiconductor data into structured digital twins, enabling automatic generation of drivers, tests, and documentation. We're building a single, traceable source of truth to make integration fast, vendor-agnostic, and future-proof.
