Do you want to work alongside engineers, scientists, and domain specialists that are experts in their fields? Are you passionate about best practices for delivering the highest quality software solutions?

Roles & Responsibilities

MITRE is seeking a Senior Agentic Software Engineer to design, build, secure, and operate mission-focused software systems and data platforms using state-of-the-art agentic and AI-enabled software development techniques. In this role, you’ll apply modern tools and practices to develop prototypes and field-ready capabilities, advise sponsors on effective adoption, and help establish guidance, best practices, and guardrails for responsible use. You’ll deliver features and technical solutions, shape system architecture and engineering process improvements, and lead both sustained program execution and rapid response mission needs.

The applicant should be prepared to work across multiple domain areas and to support a mix of standard program work and urgent, high-impact enablement tasks as organizational priorities evolve. Areas of engagement may include

Design, develop, test, and deploy mission software and data platforms using agentic/AI-assisted workflows with clear human accountability and review

Stand up and operate agentic development toolchains (code/test/review agents, copilots, automation bots) integrated into standard engineering practices

Rapidly prototype mission capabilities with agentic methods and mature them into production-grade systems (security, reliability, scalability, observability)

Define, implement, and enforce guardrails for agentic engineering (approved tools/models, data handling, secrets, provenance, auditability, safe prompting)

Establish evaluation and quality gates for AI-generated artifacts (tests, static/security analysis, coding standards, CI checks, acceptance criteria)

Architect, build, and operate distributed cloud systems (AWS/multi-cloud) using agentic techniques to manage performance, resilience, cost, and troubleshooting

Design and integrate APIs, backend services, and data flows; build and operate data pipelines and orchestration where applicable

Automate DevSecOps and CI/CD with AI-aware controls (supply-chain security, dependency/container/IaC scanning, SAST/DAST, policy-as-code) and repeatable releases

Produce and maintain documentation, runbooks, and compliance-ready evidence for AI-assisted engineering, including observability integrations (e.g., Splunk)

Basic Qualifications

Typically requires a minimum of 5 years of related experience with a Bachelor’s degree; or 3 years and a Master’s degree; or a PhD with relevant experience who can immediately contribute to this job step

Entrepreneurial, innovative, and collaborative spirit and the curiosity to explore and push the boundaries of software development and software solutions

Strong software engineering fundamentals and Python proficiency, including secure coding, code review, automated testing, and maintainable design patterns

Hands‑on experience using agentic/AI‑assisted development tools (e.g., copilot, code agents, test generation, PR review automation) and integrating them into the Software Development Life Cycle

Experience designing guardrails for AI‑enabled engineering (tool/model selection, prompt/context hygiene, secrets handling, provenance, auditability, and policy/compliance constraints)

Experience establishing quality/evaluation practices for AI‑generated outputs (automated checks, unit/integration tests, static/security analysis, and human‑in‑the‑loop review standards)

Leadership/enablement skills: mentoring, setting engineering standards, and advising stakeholders/customers on responsible adoption and change management

Must have an active Secret U.S Government issued Security Clearance. Must be eligible to obtain and maintain a Top Secret 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 requires a minimum of 3 days a week on‑site.

Preferred Qualifications

Advanced degree within technical discipline; Software Engineering, Computer Science, Computer Engineering, Mathematics, etc.

Active Top-Secret clearance preferred

Proven experience building, deploying and operating LLM/agent systems (e.g., RAG, tool/function calling, orchestration frameworks) in production, including constrained/classified environments

Mature evaluation and quality practices for LLMs/agents (e.g., golden sets, regression benchmarking, judge models; hallucination/jailbreak resistance and task success metrics)

Platform engineering/DevSecOps expertise: CI/CD delivery platforms, artifact management, and software supply‑chain/provenance controls (e.g., SBOMs, signing/attestation/SLSA, policy-as-code)

Cloud‑native operations depth across Kubernetes and IaC/multi‑cloud, with strong observability (tracing/logs/agent telemetry, audit logging/Splunk) and MLOps/model serving (hosting, gatewaying, rate/cost controls, monitoring)

This requisition requires the candidate to have a minimum of the following clearance(s)

Secret

This requisition requires the hired candidate to have or obtain, within one year from the date of hire, the following clearance(s)
