Albedo is making Very Low Earth Orbit (VLEO) mainstream, building the infrastructure to usher every satellite mission set into this new orbital domain. We build buses, integrated satellites, and turnkey missions for customers to thrive in VLEO, between 250 km - 400 km, where proximity compounds performance and drag self-cleans debris.

As part of the first 100 employees at Albedo, you will have a big impact on Albedo’s trajectory to proliferating VLEO — whether you’re advancing hardware to increase satellite longevity, scaling production for large constellations, building next-gen flight and ground software to push performance, or enabling missions that matter for national security and our day-to-day life here on earth.

How We Operate: Albedo takes a first-principles approach — in space and in business. We move with speed, take calculated risks, and learn quickly. We use AI regularly to create leverage in every discipline across the company. We work in-person at our Broomfield CO HQ to maximize team and company productivity. We work hard and with urgency to compound our first-mover advantage.

Who We're Looking For: Builders who want to own outcomes, not tasks. Systems thinkers who balance precision with iteration while thinking about the big picture. Individuals who are energized by creating a category rather than competing in an existing one. You’ll join a team that has already proven what others said wasn’t feasible and is now scaling and upgrading our VLEO buses & payloads to serve mission sets across sensing, communications, and responsive operations.

If you can feel the excitement running through your veins, apply to be one of the Bedo 100.
