Fullstack Developer - USSF XC3

We are seeking a motivated Fullstack Developer to help build and scale our AI-powered operational intelligence platform, across its React.js front end and PostgreSQL-backed services. This role sits at the intersection of modern web application development, secure backend engineering, and DevSecOps practice.

The ideal candidate has strong hands-on experience building production React.js applications, designing and optimizing PostgreSQL schemas and queries, and working within secure, CI/CD-driven development pipelines for government and enterprise environments. This position is ideal for a developer who enjoys owning features end-to-end, from data model to UI, and who takes a security-conscious approach to everyday engineering decisions.

Location

In-Person / Hybrid (US Domestic) Preferred.

Clearance

Ability to obtain and maintain a U.S. Government security clearance preferred.

Essential Role and Responsibilities

• Design, develop, and maintain React.js front-end applications
• Build and optimize PostgreSQL data models, queries, and migrations to support platform scalability
• Develop and maintain RESTful/GraphQL APIs connecting front-end and backend services
• Implement and maintain secure CI/CD pipelines, including automated testing, build, and deployment stages
• Apply secure coding practices across the stack, including input validation, authentication/authorization, and dependency management
• Collaborate with product, design, and AI engineering teams to translate requirements into shipped features
• Participate in code reviews, architecture discussions, and technical design sessions
• Troubleshoot and resolve production issues across the front-end and backend
• Support integration work with external systems (e.g., Salesforce, Outlook) as the platform’s integration footprint grows
• Contribute to technical documentation and onboarding materials for the engineering team
• Write and maintain automated tests across unit, regression, and integration levels to catch defects before they reach production

What You’ll Work On

• React.js front end and PostgreSQL-backed services
• Secure CI/CD pipeline modernization
• Cross-system integrations (Salesforce, Outlook, and beyond)
• AI-enabled workflow features
• Government and enterprise cloud deployments
• Automated test coverage across unit, regression, and integration levels

• Bachelor’s degree in Computer Science, Engineering, or related technical field (or equivalent experience)
• 5+ years of professional experience building production applications with React.js
• Strong hands-on experience with PostgreSQL, including schema design, query optimization, and migrations
• Experience building and maintaining CI/CD pipelines (e.g., GitHub Actions, GitLab CI, Jenkins)
• Solid understanding of secure software development practices and common web application security risks (e.g., OWASP Top 10)
• Experience with RESTful API design and integration
• Proficiency in JavaScript/TypeScript and modern front-end tooling
• Familiarity with version control workflows (Git) and code review practices
• Ability to work independently in a fast-paced, evolving technical environment
• Hands-on experience with automated testing frameworks and practices, spanning unit, regression, and integration testing (e.g., Jest, React Testing Library, Cypress, Playwright, or similar), * Experience with cloud-native deployments in AWS or AWS GovCloud
• Familiarity with containerization technologies (Docker, Kubernetes, ECS)
• Experience with Infrastructure as Code (Terraform, CloudFormation, or similar)
• Exposure to AI-enabled or LLM-integrated application architectures
• Experience supporting ATO, RMF, or related compliance efforts
• Active or previously held U.S. Government security clearance
• Experience supporting DoD, federal, or national security customers

Desired Traits

• Builder mindset with strong ownership and execution skills
• Comfortable operating in ambiguity and rapidly evolving technical environments
• Strong communication skills with both technical and non-technical stakeholders
• Security-conscious by default, not as an afterthought
• Ability to balance feature velocity with code quality and reliability
