Join the Rocket Ship.
SIEGE is a DARPA-origin offensive cyber platform scaling fast. We're assembling a small, exceptional team to take it to the enterprise and the mission. Get in early, own outsized impact, and help define a category. These are founding seats where the work you do compounds.
This isn't a seat. It's a stake.
SIEGE turns breakthrough offensive research into the platform that tests every attack path before an adversary does. The people who join now don't inherit a playbook. They write it.
Get in early
These are founding seats. The pipeline you build, the partners you sign, the systems you stand up, they compound into the company SIEGE becomes.
DARPA-origin technology
SIEGE was born from DARPA-origin offensive research and is now headed to the enterprise and the mission. You'll carry technology that's genuinely ahead.
Define a category
Continuous adversarial validation is a new way to think about security. Help name it, shape it, and take it to market before anyone else does.
Force-multiplied by AI
We build with agentic AI so a small team operates like a large one. Bring your own AI workflows. Here they're a superpower, not a side project.
Where you come in.
Two founding seats are open right now. Both are remote, both are high-leverage, and both plug straight into the work that sets the company's pace.
Don't see the seat that fits you? If you're exceptional and you believe in the mission, we still want to hear from you: HR@siege.com.
