What you will achieve

You’ll respond to real-time issues, automate fixes, and work closely with senior engineers to refine how we monitor and support our systems. The environments you’ll support power decisions with real-world consequences—so your ability to stay cool, think clearly, and respond fast matters.

About You

You’re a hands-on, curious, and cool-headed systems engineer who thrives in operational environments. You love chasing down the root of a weird log message, writing clean scripts to make your life easier, and knowing you’ve played a part in keeping mission-critical systems online.

You’re excited by the idea of working in a fast-paced startup that builds software for real-world military planning—not just another SaaS dashboard. You’ve supported secure, high-stakes systems before (whether in DoD settings or in production web infrastructure), and you’re looking to join a tight-knit team where your contributions will matter from day one.
