Senior Software Engineer

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. 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. Your work will directly impact mission readiness, and your mentorship will shape the next generation of engineers at Bluestaq. You'll balance hands-on delivery with technical leadership, raising the bar for code quality and system design.

Requirements

Strong proficiency in multiple programming languages and frameworks; Proven ability to design and deliver complex features across the full stack; Deep understanding of software architecture patterns and design principles; Experience with automated testing strategies and test-driven development; Track record of mentoring junior engineers and improving team practices; Strong debugging and problem-solving skills across distributed systems; Experience with cloud platforms, containerization, and modern deployment practices; Excellent communication skills and ability to explain technical concepts clearly; PhD in Computer Science, Engineering, or a related field and 0+ years of software engineering or related experience OR Master's degree in Computer Science, Engineering, or a related field and 2+ years of software engineering or related experience OR Bachelor's degree in Computer Science, Engineering, or a related field and 4+ years of software engineering or related experience OR Associate degree in a related field and 6+ years of software engineering or related experience OR High School Diploma/GED and 8+ years of software engineering or related experience; Use of modern AI tools with judgment, integrating them into workflows where impactful, reviewing outputs, and handling proprietary or sensitive data responsibly; May require an active TS/SCI Clearance

Nice to have

Experience with microservices architectures and distributed systems; Familiarity with event-driven architectures and asynchronous processing; Background in performance optimization and scalability; Experience working on government, defense, or mission-critical systems; Knowledge of security best practices and secure coding standards; Contributions to open-source projects or technical communities; Experience with observability tools and practices (logging, metrics, tracing); Familiarity with customer-facing environments, including Technical Exchange Meetings (TEMs) or similar collaborative forums with stakeholders
