Optics Intern

Overview Energy is a mission-driven team committed to building a new layer of energy infrastructure: satellites in geosynchronous orbit that redirect solar energy to terrestrial solar projects via passively safe near-infrared light. We're in the earliest phase, where the ground beacon our satellites will point to is aligned, characterized, and field-corrected end-to-end by a small, dedicated team. Headquartered in the Northern Virginia / Washington, DC area and backed by world-class investors, we are advancing the next generation of clean energy technology.

We're looking for an Optics Intern to help with the design and building of our ground beacon from the optical bench to a field test site. The beacon is the pointing reference the satellite system will depend on. If it isn't aligned and characterized correctly, nothing downstream works.

You'll work hands-on with the emitter and the observational telescope: aligning the laser, characterizing its output, and co-aligning the beacon with the telescope. Then you'll own a problem we haven't solved yet. Once the system is transported to the test site, alignment may shift. You'll design the procedure that brings it back.

This internship supports our program under a Department of War (DoW) energy investment program. You'll work alongside our optics and hardware engineers, and your alignment data will feed directly into hardware decisions we make.

• Align the beacon laser within its emitter and verify pointing outside the emitter aperture

• Characterize laser output - power, beam profile, divergence, and pointing stability - and document the results

• Co-align the beacon laser with the observational telescope and verify boresight

• Design a repeatable field alignment procedure that corrects misalignment introduced during transport and installation at the DoW site

• Write that procedure so a non-optics operator can execute it, then validate it hands-on before delivery

• Maintain clean alignment and characterization records, and feed findings back to the engineering team

• Currently enrolled in a bachelor's or master's program in optics, optical engineering, physics, or a closely related field

• Coursework or lab experience with optical alignment: mounts, mirrors, lenses, and beam paths

• Willingness to complete laser safety training and follow protocol without exception

• Careful documentation habits - alignment work is only useful if it's repeatable by someone else

• Able to commit approximately 10 hours per week from September 2026 through March 2027, on-site in Northern Virginia

• Hands-on use of beam profilers, power meters, autocollimators, or shear plates

• Telescope operation or astronomical instrumentation experience

• Zemax OpticStudio, Quadoa, Code V, or comparable optical design and analysis software

• Experience writing test or alignment procedures that other people have actually followed

• Demonstrated interest in defense, space, or energy applications

This is a paid, part-time internship running September 2026 through March 2027 at approximately 10 hours per week, based on-site at our Northern Virginia headquarters. Hourly rate: $30-$40.

You'll be mentored directly by the engineers running the program, and your work is a funded DoW deliverable, not a side project. Interns are not eligible for the full-time benefits package.
