Axiom Space fosters a work environment inclusive of all perspectives. We are the pioneers of commercial space, leading the transformation of low-Earth orbit into a global space marketplace. Our mission-driven team is seeking a bold and dynamic FPGA Design Engineer, Senior who is fueled by high accountability, execution horsepower, and driven to understand our world, science/technology, and life itself, for the benefit of all on Earth and beyond.

POSITION SUMMARY

Since Axiom Space is a very complex work environment, we are looking for a resilient, high-energy FPGA Design Engineer, Senior to develop, program, verify, and optimize configurable and programmable integrated circuits for the Axiom Extravehicular Mobility Unit (AxEMU) Portable Life Support System (PLSS).

The AxEMU PLSS contains flight computers, radios, sensors, and network switches that enable communication and control during all aspects of a spacewalk. You will be responsible for developing and programming the FPGA hardware that supports the management of commands, telemetry, and internal data flows, ensuring the suit operates reliably and meets mission objectives. Technical scope grows around that core as you learn the program: interface data checks, FPGA design, test readiness, supplier data intake, and review package preparation.

KEY DUTIES & RESPONSIBILITIES

• Create reconfigurable digital hardware solutions for embedded control, and high-speed data processing.
• Develop Register Transfer Level code using hardware description languages such as VHDL or Verilog.
• Conduct timing analysis and optimization for high-performance applications.
• Integrate IP cores and custom logic blocks into cohesive FPGA systems.
• Specify functional, performance, and environmental requirements for FPGA systems.
• Document design decisions, trade studies, and verification plans.
• Provide technical oversight during integration, system-level testing, and acceptance testing.
• Resolve technical issues and ensure the FPGA systems meet all mission-critical performance goals.
• Debug hardware issues on physical FPGA boards using standard lab tools.
• Lead vendor selection and make/buy decisions, balancing technical risk, schedule, cost, and lifecycle support.
• Evaluate commercial-off-the-shelf (COTS) components for suitability and reuse potential.
• Communicate progress, status, and issues honestly and early, including when something is not working.
Perform additional job duties as assigned.

QUALIFICATIONS: To perform this job successfully, an individual must be able to perform each essential duty satisfactorily. The requirements listed below are representative of the knowledge, skill, and/or ability required. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

Education & Experience

• Bachelor's degree from an accredited college or university in Electrical Engineering, Computer Engineering, or equivalent.
• Level 3: 5 or more years’ experience in hardware description languages and FPGA tools. An equivalent combination of education and experience may be considered.
• Experience with hardware description languages (VHDL, Verilog) for modeling, simulating, and synthesizing digital systems.
• Familiarity with FPGA tools and platforms (Xilinx Vivado, Intel Quartus, ModelSim) and FPGA board bring-up.
• Ability to implement designs, run simulations, and debug hardware effectively.
• Experience in digital and analog circuit design, including logic gates, flip-flops, multiplexers, and timing analysis.
• Skilled in simulation software (ModelSim, MATLAB, Simulink, Verdi) for virtual design test prior to hardware implementation.
• Working knowledge of scripting languages (TCL, Python) for workflow automation, generating timing constraints, and managing repetitive tasks.
• Experience in embedded systems integration including microcontrollers, sensors, and other embedded components.
• Experience working in a lab setting and proficiency working oscilloscopes, multimeters, spectrum analyzers, VNAs, and related lab equipment.
• Clear technical writing, and the ability to produce verification documentation, status material, and review packages that other people can act on.
• Curiosity, initiative, and the willingness to ask a question early rather than deliver a wrong answer late.
Comfort working in an ambiguous, fast-moving environment where the answer is often not yet written down.

Preferred Qualifications

• Experience in integration and test in spacecraft, aerospace, defense, or other high reliability programs.
• Experience with product life cycle and having worked on designs from concept through production.
• Vehicle integration experience is a plus.
• Familiarity with interface control documents, requirements management tools such as Jama or DOORS, or configuration management practice.
• Familiarity with industry or space program standards such as NASA SSRI, IEEE-ISTO-MOSA-IF-S-001, MIL-STD-1553, NASA-STD-7002, or NASA-STD-3001.
Engineer in Training certification, or progress toward professional certification.
