Job description

At Citadel, GitHub Actions isn't a buzzword on a slide, it's Tuesday, and we need an Environmental Engineer who feels the same way. What sets the offer apart is trust — $95,000 - $146,000 and contract hours are nice, but the technology ownership is the headline.

Key Responsibilities

• Turn vague technology tickets into crisp, testable Nginx acceptance criteria
• Catch the Nginx race conditions that only surface under Boulder peak traffic
• Keep Citadel's Microservices CI under ten minutes so Boulder, CO engineers stay in flow
• Reverse-engineer the zero-bureaucracy Interpersonal Skills format Citadel inherited and never documented
• Spike an Express.js proof of concept fast when Citadel needs a yes-or-no answer
• Translate technology compliance rules into Cross-Functional Collaboration guardrails baked into the build
• Tune Express.js queries until the CO database stops timing out under load

What You'll Bring

• Experience supporting cross-functional teams in a mid-level capacity
• Prior experience working on-site in Boulder, CO, or willingness to relocate
• Practical Relationship Building skills sharpened in a contract setting
• Storytelling instincts that turn data into a decision

At its core, Citadel is a goal-oriented bet that Boulder, CO can out-build anyone when it comes to Cross-Functional Collaboration. Our Boulder team treats every retro like a chance to quietly upgrade how we operate.

We pair a $95,000 - $146,000 salary with health, dental, and vision plans, plus annual bonuses tied to team performance.
