Job summary

MITRE is seeking an experienced senior software engineer to drive secure, scalable systems for national security programs. You will develop backend services, data pipelines, and APIs while shaping technical roadmaps across AWS/multi-cloud environments.

The role emphasizes strong Python skills, containerization with Docker/Kubernetes, and IaC with Terraform/Ansible, plus experience with RESTful APIs and data platforms. On-site presence is required in Chantilly, VA.

Qualifications

• Typically requires a minimum of 10 years of related experience with a Bachelor’s degree; or 8 years with a Master’s degree; or 5 years with a PhD; or an equivalent combination of education and relevant experience.
• Strong Python development experience with modern software engineering practices
• Experience building distributed systems in AWS or multi-cloud environments
• Experience with containerization and orchestration technologies (Docker, Kubernetes)
• Experience implementing DevSecOps and CI/CD pipelines
• Experience designing and integrating RESTful APIs and data pipelines
• Familiarity with databases such as PostgreSQL or MongoDB
• Experience with Linux environments and Infrastructure as Code (Terraform, Ansible)
• Experience with modern web technologies (React, JavaScript, HTML/CSS)
• Ability to work in Agile development environments with strong documentation practices
• Must have an active Top Secret/SCI w/Poly U.S Government issued Security Clearance. Per the U.S. Government’s eligibility requirements, you must be a U.S Citizen to be considered for a security clearance.
• This position has an on-site requirement of 5 days a week on-site

Responsibilities

• Deliver modern software capabilities, improving architecture, platforms, and developer workflows with strong engineering practices (secure coding, reviews, testing, maintainable design).
• Partner with UX, Architecture, Data, Security, and Operations to define technical strategy and influence roadmaps with a customer-centric mindset.
• Champion architectural excellence (cloud-native, event-driven, microservices where appropriate) across AWS/Azure, balancing long-term vision with pragmatic execution.
• Design and integrate backend services and RESTful APIs, ensuring reliable data flows for mission workflows and downstream consumers.
• Build and operate data pipelines (ETL/ELT) for ingestion, transformation, validation, and publishing to analytics and operational APIs (including Airflow orchestration as needed).
• Develop and optimize data models, SQL, and database access patterns (PostgreSQL/MongoDB), including migrations and data quality strategies.
• Implement containerized deployments with Docker/Kubernetes, including configuration, deployment patterns, and troubleshooting.
• Engineer DevSecOps/CI/CD pipelines with security and quality gates and repeatable release processes.
• Provision and manage Linux environments using Infrastructure as Code (Terraform/Ansible) for reproducible dev/test/prod deployments.
• Communicate clearly via high-quality design docs/RFCs and runbooks; lead architecture reviews, incident response, post-incident learning, and compliance/observability integration (e.g., Splunk); mentor engineers and raise standards through reviews and design sessions.
