Embedded Software Designer

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 on-orbit connectivity for critical missions, enabling a new era of data-driven intelligence 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 ofwhat’spossible in space. We believe great ideas come from diverse perspectives, andwe’recommitted to creating an environment where you can grow, lead, and make a global impact.

Ifyou’reready to reach higher, move faster, and do work that shapes the future space economy - this is your launchpad. Come build the future with Kepler
