About DMI

With a focus on end-to-end managed IT services, including managed mobility, cloud, cybersecurity, network operations, and application development, DMI supports public sector agencies and commercial enterprises around the globe. Recognized as a Top Workplace, DMI is committed to delivering secure, efﬁcient, and cost-effective solutions that drive measurable results. Learn more at www.dminc.com

About the Opportunity

DMI is seeking a Senior Full-Stack Developer to help build and modernize a mission-critical Department of Defense enterprise application. The system is an offline-first Progressive Web Application (PWA) that operates seamlessly across connected command centers, intermittent tactical networks, and fully disconnected environments.

The role spans the full stack: a React and TypeScript front end, a Node and Express back end migrating to AWS serverless, and the synchronization and integration layers that keep the product working when the network does not.

This is an AI-first engineering team. We deliver using an AI-augmented development methodology built around agentic coding tools, and fluency with those tools is a core competency of this role. Senior developers spend a meaningful share of each week directing, reviewing, and hardening AI-generated code, and they remain fully accountable for every line that ships.

Duties and Responsibilities:

Perform detailed design, development, unit and integration testing, and delivery of features spanning the front end, back end, synchronization layer, and external integrations.
Produce scalable, secure, high-quality TypeScript and Node code that satisfies both functional and non-functional requirements (performance, offline resilience, accessibility, security).
Build and maintain an offline-first PWA front end in React and TypeScript, using Redux Toolkit for state, Material UI for theming, and Vite for builds; implement service workers, background sync, and encrypted at-rest storage (IndexedDB with FIPS-validated AES-256-GCM).
Build and maintain back-end services in Express and Node using established controller and repository patterns, and contribute to the incremental migration of the monolith into domain-aligned AWS Lambda services.
Implement and migrate persistence across both MongoDB and DynamoDB, including modeling DynamoDB access patterns for single-table designs.
Develop configurable software services that integrate the application with external DoD and enterprise systems, handling data transformation, format conversion, and delta/change-data-capture synchronization while preserving data integrity for accountability workflows.
Implement multi-protocol integration (REST, SOAP, SFTP) with pluggable authentication (CAC/mTLS, OIDC, JWT, OAuth2, API key, SSH key).
Design data movement and process flows for connectivity-aware operation across online, intermittent, and disconnected modes.
Apply secure-development best practices and program design patterns, including layered authentication, role-based authorization, resource-level access control, and tamper-evident audit trails.
Use agentic AI coding tools to generate, refactor, and migrate code in logical, reviewable chunks, then direct, review, and harden that output to program quality and security standards.
Write and maintain automated tests (Jest, Vitest, Playwright, supertest, Lighthouse), participate in code reviews, and support functional, regression, performance, and accessibility testing (Section 508 / WCAG).
Create and maintain design and systems documentation, architecture decision records, API specifications (OpenAPI/Swagger), and process and data-flow diagrams.
Lead feature-area design, set and enforce coding standards, mentor mid-level developers, and own technical trade-off decisions for an assigned domain.
Collaborate with the technical delivery lead, solutions architect, DevSecOps engineers, UX designers, cybersecurity staff, and mission users within an Agile/Scrum cadence and a Git-based CI/CD pipeline.
Ensure assigned work lands within sprint and program schedules.

Qualifications

Education and Years of Experience:

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.

Required Skills and Technologies:

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

Desired and Preferred Skills:

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

Clearance, Citizenship, and Additional Requirements:

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.

Location: McLean, Virginia
