 • Drive continuous improvement initiatives focused on software quality, automation, security, and development efficiency.

REQUIRED EXPERIENCE:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field.
 • Minimum of 7 years of full-stack software development experience using .NET Core and modern front-end frameworks.
 • Minimum of 3 years of experience developing applications using the Angular Framework.
 • Strong expertise in RESTful API design, microservices architecture, and secure coding standards.
 • Experience designing and developing enterprise-scale web applications in compliance-driven environments.
 • Strong proficiency with relational database systems such as PostgreSQL, including database design and performance optimization.
 • Experience conducting code reviews, mentoring developers, and contributing to technical leadership initiatives.
 • Excellent communication, collaboration, and problem-solving skills in a cross-functional team environment.
 • Must be available to work full-time and on-site in the Washington D.C. metro area.
 • U.S. Citizenship and active Secret Clearance are required.

DESIRED EXPERIENCE:

• Experience developing solutions for secure, compliance-driven federal or Department of Defense environments.
 • Experience with cloud-native application development and deployments in AWS, Azure, or similar cloud platforms.
 • Experience with containerization and orchestration technologies such as Docker and Kubernetes.
