Satellite Systems Designer - Analysis & Support

At Kepler Communications, we’re not just imagining the future of on‑demand space connectivity – we’re leading it! Our mission is to provide real‑time Internet access for space‑based assets, enabling a new era of data‑driven exploration and innovation. With 33 satellites launched to date, Kepler operates the first commercial optical data relay constellation, enabling real‑time, continuous space communications while supporting advanced on‑orbit compute and hosted payload capabilities.

Industry‑leading technology is only part of the story. What sets Kepler apart is our team: bold thinkers, skilled builders, and passionate problem‑solvers who thrive on pushing the boundaries of what’s possible in space. We believe great ideas come from diverse perspectives, and we’re committed to creating an environment where you can grow, lead, and make a global impact.

If you’re ready to reach higher, move faster, and do work that shapes the future space economy – this is your launchpad. Come build the future with Kepler!
