MITRE is seeking a Senior Software Engineer to design, build, secure, and operate mission-focused software systems and data platforms. The role emphasizes Python development, AWS cloud-native and distributed architectures, DevSecOps automation, and data engineering/ETL to support analytical and operational use cases. The candidate will deliver features and technical solutions, contribute to system architecture and engineering process improvements, and support both sustained program delivery and fast-turn mission needs.

The candidate should be prepared to work across multiple technology areas (cloud infrastructure, software engineering, and data engineering) and to support a mix of standard program work and urgent, high-impact enablement tasks as organizational priorities evolve. Responsibilities may include some or all of:

• 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.

• Advanced degree in a technical discipline (including but not limited to Software Engineering, Computer Science, Computer Engineering, Mathematics, etc.)
• Experience delivering software in compliance-aligned environments and hardening systems to standards such as NIST 800-171 and/or NIST 800-53, including producing audit-ready evidence
• Experience building and operating AWS data platforms (e.g., Glue, EMR) and implementing automated data quality validation and monitoring
• Experience with workflow orchestration and streaming/event platforms such as Airflow and/or Kafka
• Experience with cloud automation and Infrastructure as Code beyond baseline use (e.g., reusable Terraform modules, AWS CDK patterns, environment promotion strategies)
• Experience with observability platforms such as Splunk, including onboarding data sources, parsing, dashboards, and alerting to support security/compliance and operational readiness
• Experience supporting mission analysis, test and evaluation, operational systems, and/or integration with external mission partners or vendor solutions
• Experience with simulation environments such as AFSIM
• Experience administering or operating production systems (applications, databases, and/or networks), including incident response practices and reliability improvements
