10+ years of software engineering experience, with a track record of shipping and supporting production applications; scope and technical leadership appropriate to Senior or Staff level.
5+ years of hands-on full-stack development spanning modern web frontends, backend services, APIs, and databases.
Strong frontend skills with TypeScript/JavaScript and React, Next.js, or comparable frameworks, including state management, API integration, and clear, accessible user experiences.
Strong backend engineering skills in Python, TypeScript/Node.js, Go, Java, or a similar language, including API design, service integration, validation, and error handling.
Experience designing data models and working with relational databases, migrations, caching, and asynchronous or event-driven processing.
Experience implementing authentication, authorization, secure API access, secrets handling, and audit logging in production applications.
Hands-on experience with automated testing, code review, Git, containers, CI/CD, and deploying or troubleshooting applications in cloud or Kubernetes environments.
Ability to debug across browser, service, API, and data layers using logs, metrics, and traces, and to own issues through validated resolution.
Strong technical judgment, clear written and verbal communication, and experience translating ambiguous customer requirements into maintainable solutions and useful documentation.
Experience using AI-assisted engineering tools to improve implementation, testing, troubleshooting, or code review, with careful validation of the resulting changes.
Prior full-stack software engineering experience supporting national security, defense, federal agencies, or other government programs is strongly preferred.
An active U.S. government security clearance is strongly preferred.
Experience with federal application security and delivery requirements, such as STIG hardening, NIST controls, RMF/ATO evidence, FedRAMP, or DoD impact-level environments is strongly preferred.
Experience integrating identity providers such as Keycloak using OAuth/OIDC, or implementing fine-grained access and sensitive-data controls is strongly preferred.
Experience building AI/LLM applications, agent integrations, RAG, tool/MCP connections, evaluations, or workflow systems such as Temporal is strongly preferred.
Customer-facing or forward-deployed engineering experience across multiple partner organizations is strongly preferred.
Experience adapting applications for government cloud, restricted-network, or on-premises deployments is strongly preferred.
