Dan Roelker’s career path doesn’t make sense until you see the pattern. Hacker, video game developer, SpaceX software lead, crypto — and now he’s building telescopes. He runs a company called Observable Space, and he’ll tell you straight up: “If you can control light, you control space.”
Roelker grew up working-class in Pennsylvania, studied math and philosophy at Johns Hopkins, and got hooked on computers and hacking in the late ’90s. He ended up at Sourcefire (later acquired by Cisco for $2.7 billion), then moved into offensive cyberwarfare roles at companies later bought by BAE Systems and Raytheon.
By his early 30s, DARPA recruited him to manage cyberwarfare initiatives. He ran Plan X — one of the first public acknowledgments that the US military was building offensive cyber capabilities. Pretty big deal.
After four years at DARPA, he needed a reset. He tried working on League of Legends at Riot Games — played mid, mained Diana — but the urgency wasn’t there. A friend connected him to SpaceX, and he joined in September 2014, right after a Falcon 9 blew up. The software team was eight months behind. Half of them were about to quit. On his first day, someone told him “good luck” and walked away.
He cut scope, focused the team on flight software and the first-stage landing, and they pulled it off on December 21, 2014. First orbital rocket landing in history.
Now he’s back in the optics game. Observable Space is building advanced telescopes and the software to run them, tracking the ever-growing swarm of satellites and using laser communications to beam data from orbit. “The new space race is going to be on the ground,” he says. Whoever controls the light wins.
