Senior Full Stack Developer

• 10 or more years of overall software development experience.
• Five or more years of professional experience in Node, TypeScript, and React.
• Three or more years of building on AWS serverless.
• Bachelor's degree in Computer Science, Software Engineering, or a related field. Master's preferred.
• Equivalency: a Master's degree substitutes for two years of experience, and an Associate's degree plus four years substitutes for a Bachelor's. Security clearance and citizenship are non-waivable and carry no equivalency.

• Languages and runtime: TypeScript, modern JavaScript (ES2022+), Node.js 24
• Front end: React (hooks, function components), Redux Toolkit, Material UI, and Vite; Progressive Web App development including service workers, Workbox, IndexedDB, background sync, and offline-first architecture; accessibility to Section 508 / WCAG
• Back end and data: Express REST APIs using controller and repository patterns; MongoDB (Mongoose) and DynamoDB (single-table design and access-pattern modeling), with experience migrating from document or relational stores to DynamoDB strongly desired; API design with OpenAPI/Swagger
• Cloud and serverless: AWS Lambda, DynamoDB, API Gateway, Step Functions, EventBridge, and SQS; a managed-service-first approach that favors AWS managed services over bespoke plumbing where they fit; incremental monolith-to-serverless (Strangler Fig) migration patterns; AWS GovCloud exposure (IL5/IL6) desired
• Integration and synchronization: multi-protocol integration across REST, SOAP, and SFTP; authentication schemes including CAC/mTLS, OIDC, JWT, OAuth2, API keys, and SSH keys; delta/CDC synchronization, ETL and data transformation, and legacy-system integration
• Security and compliance: secure coding for DoD and government environments; AES-256-GCM and FIPS 140-3 crypto awareness; RBAC and audit logging; familiarity with RMF, STIG, and NIST 800-53 expectations in a delivery context
• Tooling and process: Git and CI/CD (GitHub Actions) or GitLab; monorepo discipline; Jest, Vitest, Playwright, supertest, and Lighthouse; Docker and containerized local development; Agile/Scrum ceremonies
• AI-augmented development (core competency): hands-on fluency with agentic AI coding tools, with Claude Code and Claude Opus strongly preferred and GitHub Copilot, Cursor, or comparable agentic tools accepted as transferable experience; effective spec-writing and prompting, chunked generation, and rigorous review and hardening of AI-generated code for correctness and security

• AWS Certified Developer (Associate) or AWS Solutions Architect (Associate)
• Prior DoD or federal digital modernization experience, and familiarity with military or government accountability and readiness workflows
• Experience designing for disconnected, intermittent, and low-bandwidth (DDIL) environments
• Experience integrating with DoD personnel, logistics, or records systems
• Experience with the Model Context Protocol (MCP), retrieval-augmented generation (RAG), or large-language-model provider abstraction and failover patterns
• Experience with multiple AI inference deployment models, including commercial cloud, sovereign cloud, and on-device or edge
• AWS Lambda Powertools, CloudWatch, and X-Ray observability, and infrastructure-as-code (CloudFormation, CDK, or Terraform)
• Performance testing (k6) and visual-regression or Storybook testing
• Comfort working in air-gapped environments where cloud and external tooling, including AI tooling, are unavailable

• Security clearance: Active DoD SECRET required at start of work. An interim SECRET may be accepted for transition per contract terms, with final SECRET required within 90 days. Ability to obtain Top Secret is preferred.
• Citizenship: U.S. Citizen required. This position has no foreign-national or dual-citizenship accommodation.
• DoD 8570/8140: personnel performing Information Assurance functions must meet the applicable IAT or IAM certification baseline and maintain currency throughout the period of performance.
• Contract vehicle: ITES-3S, Functional Area 3 (Software Development Services). This role is designated Key Personnel.
• Physical requirements: none specific to this position. Standard remote knowledge-work conditions apply. The candidate must work from a U.S.-based location suitable for handling controlled unclassified information.
