• The ideal candidate thrives in a mixed-stack environment, primarily utilizing Python and Java Spring Boot, and is comfortable leveraging modern AI development tools to accelerate their workflow.

• You will operate with a high degree of autonomy to drive continuous improvement and system reliability. 

Responsibilities:

• Automate and provision foundational infrastructure to support mission-critical customer requirements.

• Leverage AI-assisted development tools to enhance coding speed, debugging, and overall software delivery.

• Operate with a high degree of autonomy, moving beyond standard ticket resolution to drive strategic process improvements and system optimizations.

• Possess an active or rein-statable TS/SCI with Polygraph security clearance. (This position requires in-scope poly, within 7 years).

• U.S. Citizenship.

• 12+ years Software Engineering experience and a BS degree in Computer Science or related. Four (4) years of additional SWE experience on projects with similar software processes may be substituted for a bachelor’s degree.

• Works well independently as well as on a team. 

• Strong communication skills. 

Key Skills:

• Production-grade software development experience in Python and/or Java (Spring Boot).

• Proven track record as a self-starter capable of independently identifying system inefficiencies and driving them to resolution.

• Experience integrating AI development tools into daily engineering workflows.

• Strong problem-solving skills with a focus on infrastructure automation and process optimization.

• Familiarity with version control systems, specifically Git.

Desired Skills:

• Experience designing and implementing automated deployment pipelines using GitLab CI/CD.

• Hands-on experience with service containerization and deploying containerized applications (e.g., Docker).

• Familiarity working within containerized environments or orchestration platforms (e.g., Kubernetes).

• Experience bridging multiple technical domains in a complex, mixed tech stack environment.
