Electrical Engineer - IRL

Interlune is a space resources company based in Seattle, WA. We will provide resources from space to power a clean and sustainable economy on Earth and in space.

We are looking for a Doer who wants to join our early-stage team and accelerate humanity’s progress toward an off-world future. Our engineering team combines expert knowledge of geological sciences, mechanical engineering, automation, systems engineering, modeling and simulation, and advanced fabrication to build the infrastructure that will create an in-space economy. To join our small team, you must be agile, willing to learn, and able to take on multiple roles as needed.

As an Electrical Engineer, this role will join Interlune’s engineering team and be responsible for the physical design, development, and implementation of the critical hardware that will make space resource utilization possible. This position would be full time at the Interlune Research Lab (IRL) in Houston, TX.

Applicants from all industries are welcome, with particular emphasis in complex, multi-disciplinary system development. Familiarity with and prior experience in the space, agriculture, construction, or mining industry are valuable but not required.

• Contribute to the design, build, and qualification of hardware for a variety of lunar applications, that will include high-voltage systems, power electronics, and control avionics.
• Perform schematic capture, PCB layout, and harnessing definition for prototype test rigs and hardware setups at the Houston lab.
• Participate in hands-on lab bring-up, debugging, assembly, and maintenance of test hardware and data acquisition systems.
• Support space environment simulation testing, including thermal vacuum chamber runs and plasma/charging interaction testing for broad lunar infrastructure hardware.
• Work closely with senior engineers to implement ESD mitigation, EMI shielding, and safety procedures for high-voltage and dusty environment testing.
• Document test procedures, test results, and design revisions to support broader lunar infrastructure and engineering teams.

• B.S. in Electrical Engineering, Computer Engineering, or a related technical field.
• 0–3 years of experience (or relevant internship/academic project experience) in electrical hardware design, test engineering, or lab instrumentation.
• Foundational knowledge of circuit design, power electronics, and basic high-voltage safety principles.
• Familiarity with ECAD software (e.g., Altium Designer, KiCad) for schematic capture and basic PCB layout.
• Hands-on experience using standard lab equipment (oscilloscopes, digital multimeters, power supplies, logic analyzers).
• Strong problem-solving ability, self-motivation, and willingness to learn complex space environment test setups.
• Excellent written and verbal communication skills.
• Ability to collaborate effectively in a fast-paced, multi-disciplinary lab environment.

• M.S. in Electrical Engineering or related technical field.
• Prior experience or coursework with high-voltage systems (1 kV+) or high-fidelity regolith simulant testing.
• Experience operating or testing within thermal vacuum (TVAC) or space environment simulation chambers.
• Basic understanding of lunar surface plasma, charging effects, or dust mitigation technologies.
• Software/scripting experience (e.g., Python, MATLAB) for test automation and data analysis.
