Backend Software Developer

About

If you have a strong background in backend engineering, proficient in Java or Python development, particularly in mission-driven environments, we have an exceptional opportunity for you. This role is designed for engineers who aspire to create a meaningful impact and take pride in their work. If you write your own résumé and consistently deliver results that are noticed by senior management, you'll excel in our team.

We are looking for a Backend Software Developer to contribute to a high visibility application that supports data analysis, reporting, and operational decision-making across the organization. Your responsibilities will include designing and building scalable backend services, developing RESTful APIs, integrating complex data sources, and ensuring high reliability and performance in a Linux-based environment.

Our primary development team is located in Gaithersburg, MD, but we also support onsite engineers in Alexandria, VA; Chantilly, VA; Aurora, CO; St. Louis, MO; and Tucson, AZ, offering multiple paths for top talent to join our mission.

Even though the qualifications may appear standard, this position is unique as it will place you in a high-performing team that is revolutionizing digital engineering and mission operations intelligence for our clients.

Why This Role Stands Out

• High Impact: Your contributions will power a widely used application that influences real-time decisions.
• High Visibility: Engage directly with engineering teams and mission stakeholders.
• Career Growth: Enhance your expertise in backend architecture, API design, and scalable systems.
• Challenging Work: Build and optimize intricate backend features.

Key Responsibilities

• Backend Development: Design, develop, test, and maintain backend services using Java or Python.
• REST API Development: Design and implement RESTful services for application functionality and integrations.
• Object-Oriented Design: Employ strong object-oriented design principles to create scalable and maintainable systems.
• Database Development: Write and optimize SQL queries to support application functionality and performance.
• Data Source Integration Coordination: Collaborate with external teams to comprehend data sources, interfaces, and access patterns, translating requirements into backend integrations.
• System Design Contribution: Engage in technical design discussions and influence backend architecture decisions.
• Linux Environments: Develop, deploy, and troubleshoot applications within Linux-based operating environments.
• System Troubleshooting: Identify and resolve issues across application and database layers.
• Code Quality & Best Practices: Participate in code reviews and uphold engineering standards.

Basic Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or related field with 8-12 years of experience; or a Master's degree with 6-10 years of experience.
• U.S. Citizenship.
• Active TS/SCI clearance with the ability to pass a Polygraph.
• Extensive professional experience in developing backend applications in Java or Python.
• Demonstrated ability to design and develop RESTful APIs that deliver scalable application functionality.
• Strong SQL experience, including the development and optimization of queries across relational databases.
• Proficiency in working within Linux-based environments.
• Ability to work independently and tackle moderately complex and intricate technical challenges.

Preferred Qualifications

• Familiarity with Apache Airflow or similar workflow orchestration technologies.
• Experience in working with geospatial data and querying (e.g., PostGIS).
• Experience with Spring Boot, Django, or similar backend frameworks.
• Experience with CI/CD pipelines (GitLab, Jenkins, etc.).
• Knowledge of containerization (Docker, OpenShift, Kubernetes).
• Experience in cloud environments (AWS or Azure).
• Experience in Agile development environments.
