They usually have a few years of professional experience and are proficient in programming languages like Java, Python, Node.js, or Ruby. These developers are responsible for ensuring that data flows efficiently between the server and users, optimizing performance, and collaborating with front-end developers and other team members.

Familiarity with frameworks (such as Spring or Express), RESTful API development, version control systems (like Git), and containerization tools (like Docker) is typically required. Effective problem-solving, collaboration, and clear communication are standout soft skills for this role. These abilities are crucial for building reliable, scalable backend systems and working efficiently within development teams.

As a Mid Level Backend Developer, you may frequently encounter challenges related to maintaining code quality and ensuring scalability as applications grow. Managing database performance, optimizing API responses, and integrating with legacy systems are common tasks that require both technical skill and problem-solving ability. Collaboration with frontend developers, DevOps engineers, and QA testers is essential to ensure smooth deployments and consistent user experiences. Staying up-to-date with new frameworks and technologies, while balancing project deadlines, is also a key part of the role.

Job description

Description

If you’ve been building your skills in backend development, object‑oriented programming, and mission‑driven engineering, and you’re ready for work that actually moves the needle, this is the kind of opportunity cleared engineers pursue when they want to grow while making real impact. If you take pride in your craft, enjoy solving meaningful technical problems, and want your work to support a mission with visibility at senior levels, you’ll thrive here.

The primary development team operates out of Gaithersburg, MD, with onsite engineers in Alexandria, VA; Chantilly, VA; Aurora, CO; St. Louis, MO; and Tucson, AZ, giving top talent multiple paths to join the mission.

  • 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
  • US Citizenship
  • 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
