About the Role   Bluestaq is seeking a Senior Software Engineer to lead medium-sized features, improve code quality, and mentor early-career teammates on mission-critical systems. You'll own features and modules that span multiple components and services, working with product, design, and other engineering teams to deliver reliable, maintainable software that supports national security and defense missions.   Why This Role Matters   Senior Software Engineers are the technical anchors of our teams. You'll be the go-to person for a domain or service, ensuring that what we ship is not only functional but well-designed, tested, and sustainable.

Salary Range (CO) $100,000 — $155,000 USD Clearance Requirement:  This position may require the ability to obtain a TS/SCI Clearance.

About Bluestaq At Bluestaq, we build secure data platforms that matter for space missions, national defense, healthcare systems, and commercial innovation. Founded in 2018, we've become a leader in enterprise software and secure data management by staying focused on what counts: modern architecture, operational excellence, and mission impact. We're engineers, problem-solvers, and builders who take the mission seriously, but not ourselves. We automate the repeatable, question the status quo, and design systems that are as reliable as they are scalable. Whether we're supporting space, defense systems, or healthcare advancements, we build with the same principles: cloud-native solutions, security by design, and relentless simplicity. Relocation:  This position does not offer relocation. Candidates must live in the immediate area or relocate at their own expense.
