Technical Debt Engineer
This role is contingent upon contract funding.
Lyntris is a defense technology company that connects sensing to action across the connected battlespace. Lyntris brings together the talents of Accelint and Vitesse teams under one mission, with each contributing deep expertise within their domain. Combining differentiated hardware, software and mission expertise, Lyntris helps customers sense threats, make sense of complex conditions and act with greater speed, precision and confidence in contested environments.
Lyntris supports U.S. and allied defense organizations across every branch — including Navy, Army, Air Force, Space Force and allied partners — spanning strategic, operational and tactical missions and every domain: Space, Air, Land, Sea and Cyber. With more than 200 active defense programs, Lyntris works at every level of the mission, from national command authority to the tactical edge.
Solutions are designed by operators who understand the mission, engineered for the conditions that degrade or defeat standard systems, and built on an open, modular architecture that integrates into existing programs without requiring them to start over. Lyntris moves faster than the traditional defense cycle — with integrated design, build and test capabilities in-house — and delivers systems that sustain and endure long after initial fielding.
We are seeking an experienced Technical Debt Engineer/Software Sustainment Engineer to improve, modernize, and sustain complex software systems supporting defense and mission-critical environments. The ideal candidate will have extensive experience debugging production software, performing root cause analysis, refactoring legacy code, and reducing technical debt while preserving functional behavior and delivery schedules. This role will collaborate closely with software developers, systems engineers, architects, and government stakeholders to improve software quality, maintainability, performance, and interoperability through modern engineering and DevOps practices.
Duties & Responsibilities
- Debug, analyze, and resolve complex software defects across large-scale, distributed software systems.
- Perform root cause analysis to identify software defects, performance bottlenecks, integration issues, and reliability concerns.
- Refactor legacy software to improve maintainability, modularity, extensibility, testability, and long-term sustainability while preserving existing functionality.
- Identify, prioritize, and remediate technical debt in collaboration with engineering teams and program leadership.
- Improve software quality through static analysis, automated testing, code reviews, performance optimization, and modern software engineering practices.
- Develop, maintain, and optimize CI/CD pipelines and automated build, test, and deployment processes.
- Utilize DevOps tools such as SonarQube, GitLab CI/CD, automated testing frameworks, and containerized development environments to support continuous software improvement.
- Maintain and troubleshoot multi-language build environments using tools such as CMake, Conan, Maven, Poetry, and NPM.
- Debug and resolve interoperability and integration issues across distributed software systems utilizing standards-based APIs, messaging frameworks, and communication protocols.
- Collaborate with software developers, systems engineers, architects, and government stakeholders to implement sustainable software improvements while minimizing program risk and maintaining delivery schedules.
- Support software integration, verification, validation, configuration management, and release activities.
- Document software changes, technical debt remediation efforts, and engineering recommendations.
- Performs other duties as assigned.
Required Qualifications
- Bachelor's degree in Computer Science, Software Engineering, Computer Engineering, Electrical Engineering, or a related technical discipline (or equivalent practical experience).
- 5+ year
