Senior Software Engineer (Denver)

Crosscheck Staffing is currently working with a well-funded startup approaching Series A funding.

This is a hands-on role focused primarily on backend systems, APIs, and integrations, with occasional frontend work. Youll be joining a small, highly collaborative team at an inflection point as the company gains momentum and prepares for its next phase of growth.

What Were Looking For

• Strong backend engineer with experience building and owning production APIs
• Hands-on experience integrating third-party APIs and external systems
• Comfortable owning features end-to-end in a small, early-stage team
• Familiarity with modern backend languages and frameworks (Node / TypeScript, Python, Go, etc.)
• Willingness to contribute to frontend work when needed (not a frontend-heavy role)
• Enjoys in-person collaboration and early-stage startup environments
