You’ll help build and maintain core backend services, develop RESTful APIs, support data-driven functionality, and contribute to ongoing system enhancements within a Linux-based environment. Your work will directly support system reliability, performance, and data accuracy for mission stakeholders.

Why This Role Stands Out

• High Impact: Your work supports a widely used application that drives real-time decision-making
• High Visibility: Collaborate with engineering teams and mission stakeholders across programs
• Career Growth: Build deeper expertise in backend development, API design, and scalable systems
• Challenging Work: Contribute to complex backend features - not routine maintenance tasks

Description

• Backend Development: Design, develop, test, and maintain backend application components using Java or Python

• Linux Environments: Develop and troubleshoot applications within Linux-based environments
• Data Processing & Business Logic: Implement backend logic for data transformation, processing, and system workflows
• Bug Fixing & Enhancements: Identify, debug, and resolve application-level defects and performance issues
• Code Quality: Follow coding standards, participate in code reviews, and support documentation efforts

Basic Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related field with 4-8 years of experience; or a Master’s degree with 2-6 years of experience
• Active TS/SCI with the ability to successfully pass a Polygraph
• Professional experience developing object-oriented applications in Java or Python
• Hands-on experience building and maintaining RESTful APIs
• Basic to moderate experience with SQL capability, including writing queries and working with relational databases
• Working knowledge of Linux-based environments
• Ability to work independently on defined tasks within established technical frameworks and deliver reliable results

Preferred Qualifications

• Experience with Apache Airflow or similar workflow orchestration technologies
• Experience with Spring Boot, Django, or similar backend frameworks
• Exposure to CI/CD pipelines (GitLab, Jenkins, etc.)
• Familiarity with containerization (Docker, OpenShift)
• Exposure to cloud environments (AWS or Azure)
• Experience working in Agile development environments
• Health insurance
• Paid time off
• Vision insurance
• Paid holidays

Salary: $87,100 - $157,450 Annually
