• Develop scalable services using containerized workloads, including Docker, orchestrated with Kubernetes.

• Support cloud deployments such as AWS or Azure, including IaC using Terraform or CloudFormation.

• Contribute to modern DevSecOps practices, including automated testing, code quality enforcement, GitLab, GitHub, CI/CD pipelines, and security scanning.

• Participate in Agile sprint planning, backlog refinement, peer code reviews, and user‑focused design discussions.

• Integrate data, ML‑enabled, or analytic pipeline components into mission workflows, working closely with data engineers and analysts.

• Troubleshoot issues across the full stack and contribute to team‑wide engineering improvements.

You Have

• 4+ years of experience with full‑stack software development.

• Experience with modern object‑oriented languages such as Python, C++, or Java.

• Experience with at least one frontend framework such as React, Angular, or Vue or with HTML, CSS, and JavaScript.

• Experience developing and consuming FastAPI, REST, gRPC, or GraphQL APIs.

• Experience with Docker and Kubernetes.

• Experience deploying to AWS or Azure cloud environments.

• Experience with GitLab, GitHub, or Jenkins CI/CD automation.

• Experience working with SQL or NoSQL databases such as PostgreSQL, DynamoDB, MongoDB, or SQLite.

• Active TS/SCI clearance; willingness to take a polygraph exam.

• Bachelor's degree in a STEM field.

Nice If You Have

• Experience with Agile methodology, extreme programming, software engineering, product management, and software products.

• Experience with microservices patterns, event‑driven architectures, or message queues including Kafka, SNS, or SQS.

• Experience integrating synthetic data, analytic models, or ML pipelines into applications.

• Experience with Elasticsearch, OpenSearch, or distributed search systems.

• Experience with user‑centered design or reusable component libraries.

• Experience with AI‑augmented development workflows or agentic tools, such as Codex, Claude Code, or OpenCode.

• Master's degree in Computer Science or Software Engineering.
