• Ensure robust authentication, authorization, and secure coding practices.
• Apply Agile/SAFe methodologies and maintain clear documentation of codebases and processes.

What Required Skills You'll Bring:

• U.S. Citizenship with an active Secret clearance and ability and willingness to obtain a TS/SCI.
• Bachelor's degree in computer science or a related field (or 4 years of additional experience in lieu).
• 8+ years of experience in software development with both front-end and back-end technologies.
• Strong programming skills in a few of the following: Python, Java, JavaScript, Go, and SQL.
• Develop RESTful APIs and microservices using Python (Flask, FastAPI, Django) and other modern frameworks.
• Expertise in containerized application development and management. Preferably with a strong familiarity of Docker & Kubernetes, including deploying, managing, and scaling containerized applications, as well as troubleshooting and optimizing workloads within a cluster.
• Proficiency with RESTful API design, data visualization, database architecture (SQL/NoSQL), and version control (Git).
• Familiarity with CI/CD pipelines, DevSecOps practices, and automation tools (e.g., Jenkins, GitLab CI/CD, Terraform, Ansible).
• Experience with front-end frameworks and responsive design principles.
• Experience with cloud platforms (AWS, Azure, or Google Cloud) and infrastructure as code (IaC).
• Strong debugging and performance optimization skills for distributed systems.

What Desired Skills You'll Bring:

• Experience with Kafka, RabbitMQ, NATS , or message-driven architectures.
• Familiarity with GraphQL, WebSockets, and modern data service protocols.
