Your space-enabled career begins here

The Opportunity

We are seeking an Electrical Engineering Intern to help take real spacecraft hardware from concept to flight readiness. Interns at Lux Aeterna design circuits, build hardware, run tests, and help solve real flight problems.

You will work directly with our team to create a reusable spacecraft’s electrical system that must survive launch, operate on orbit, safely return to Earth, and be refurbished in preparation for the next launch. The role spans avionics, power systems, harnessing, test equipment, and hands-on problem solving .

This is a unique opportunity to:

• Work on real flight hardware in addition to prototypes and engineering units

• Be a member of a small and agile team pushing the limits of space innovation

• Participate in spacecraft build, integration, and test activities

• Debug issues discovered during integration and testing

• Learn how spacecraft electrical systems are developed in a rapid hardware environment

The Role

You will support responsible engineers for the first time assembly, test, debug, and delivery of EM and flight electrical hardware. Interns are expected to engage directly with hardware and help drive progress of overall spacecraft maturity.

Responsibilities include:

• Supporting manufacturing, assembly, and integration of flight electrical hardware

• Flight and ground test harness design and manufacture

• Participating in qualification and acceptance testing

• Collecting test data and helping determine root cause of electrical issues

• Performing focused analyses to support engineering decisions

• Circuit design, simulation, and manufacture of PCBs for spacecraft and ground test

• Updating schematics, PCB layouts, and documentation based on build and test feedback

• Working closely with technicians and engineers during hands-on integration activities

Required Qualifications

• Junior-level undergraduate student or higher pursuing Electrical Engineering or related degree

• Hands-on engineering experience through projects, labs, internships, or personal builds

• Understanding of circuit analysis and electronics fundamentals

• Experience with schematic capture and PCB layout tools

• Ability to work in a fast-paced team environment and take ownership of tasks

Preferred Experience

• Leadership or significant contribution in engineering extracurriculars (rocketry team, Formula SAE, robotics, CubeSat, Baja, etc.)

• Experience assembling, testing, and troubleshooting electrical systems

• Exposure to power electronics, embedded systems, and digital communication protocols

• Experience with test equipment (oscilloscopes, power supplies, logic analyzers)

• Comfort working in lab and integration environments

• Referrals from faculty, professors, or previous managers welcome & will strengthen your application.

• We are based in Denver, CO and believe in the power of in-person collaboration. We are onsite 5 days/week by default, but flexible when life requires it.
