Avionics FPGA Engineer

About Lodestar

Lodestar's mission is to develop the first "Protect and Defend" capability for high-value space assets in orbit. Our flagship product, MITHRIL, is our hardware-agnostic, AI-enabled autonomy software suite that enables us to augment any off-the-shelf spacecraft with the ability to autonomously detect, characterise, and reversibly neutralise orbital threats. By building on the proven space heritage of our best-in-class satellite-bus partners and fully integrating MITHRIL into a single unified platform, we deliver an end-to-end, autonomous in-space bodyguarding service.

About the Job

We are seeking a highly motivated Avionics FPGA Engineer to join our multidisciplinary team developing next-generation space systems. You will be responsible for designing, implementing, and validating advanced avionics architectures for autonomous platforms. This role offers the opportunity to work hands-on across the full lifecycle, from concept and simulation to hardware testing and on-orbit readiness.

What You’ll Do

Design, develop, and verify RTL in SystemVerilog and/or Verilog for FPGA and SoC targets.

Bring up and integrate SerDes interfaces and memory interfaces.

Develop testbenches and formal proofs to ensure module and system level correctness

Conduct hardware debugging and system level testing using oscilloscopes, logic analysers, and other lab instrumentation.

Collaborate closely with systems, avionics software and hardware teams to ensure seamless integration of RTL designs into flight systems.

Contribute to design documentation, test plans, and the evidence needed for design reviews, and support environmental qualification and verification testing (EMC, vibration, thermal vacuum, etc.)

Qualifications

BEng / MEng in Electrical Engineering, a related field, or equivalent experience.

Proficiency in SystemVerilog and/or Verilog, with a solid grasp of RTL design principles.

Hands-on experience with at least one FPGA family or ecosystem

Familiarity with common digital interfaces and protocols (SPI, I2C, UART)

Experience with simulation and formal verification

Experience dealing with clock domain crossings, static timing analysis and timing closure.

Comfort scripting for automation, ideally in Python and/or TCL.

Hands on experience with lab test equipment including oscilloscopes, logic analysers, and power supplies.

Clear communication and a proactive, curious approach to picking up new tools and ideas.

Preferred Skills & Experience

High speed interfaces: MIPI-CSI, QSGMII, SGMII, 10GBASE-KR, PCIe or similar.

Memory interfaces: DDR3, DDR4, LPDDR4 or similar

SoC design: integrating RISC-V or Arm processor subsystems, AXI/APB/AHB protocols, and embedded Linux bring-up.

Experience with PCB design for high speed digital designs.

Strong knowledge of verification methodologies, functional coverage, assertions and constrained random verification

Experience with Microchip FPGAs and development tools.

Background in space rated electronics and high reliability design practices, including radiation effects analysis, fault tolerant architectures, and qualification processes for space systems.

Time-Sensitive Networking (TSN) or other deterministic networking.

Compensation & Benefits
