The Opportunity:
As part of the Clairvoyant program, you will design and build the primary touchpoint between our platform and its customers - a sophisticated API layer and modern web UI delivering critical, real-time data to third-party partners.
As a Mid-Senior Full Stack Developer, you will operate within a hardened, AWS-based, Kubernetes-native environment where modern interface standards meet strict government security requirements. This is a high-visibility role where you will:
  • Engineer the Interface: Build responsive web applications using React that visualize complex, real-time data sets for external customers.
  • Architect the API Layer: Design and maintain RESTful or GraphQL APIs supporting seamless third-party integrations at scale.
  • Secure the Stack: Implement OAuth2, OIDC, and mTLS protocols and ensure all code meets DISA STIG and OWASP standards.
  • Own the Lifecycle: Drive the full SDLC from agile requirements through automated CI/CD deployment on Kubernetes.

Responsibilities:
  • Design and maintain responsive front-end applications using React, handling complex data visualization and high-concurrency use cases for external partners.
  • Build and maintain scalable RESTful and GraphQL APIs using Node.js, Python (FastAPI/Flask), or Java (Spring Boot) for third-party data access.
  • Implement authentication and authorization patterns including OAuth2, OIDC, mTLS, and RBAC to ensure secure external data access.
  • Design and optimize relational (PostgreSQL) and non-relational (Elasticsearch, Redis) data store interactions.
  • Containerize applications with Docker and deploy to Kubernetes on AWS in coordination with the DevSecOps team.
  • Ensure all code meets DISA STIG requirements and addresses the OWASP Top 10 throughout the development lifecycle.
  • Integrate with GitLab CI/CD pipelines and Helm charts for deployment across environments.
  • Conduct code reviews, provide technical guidance for junior developers, and serve as the SME for third-party API integration.
  • Maintain technical documentation, API specifications, and integration guides.

Qualifications:
Required:
  • Current TS/SCI clearance with Polygraph.
  • Bachelor's degree in Computer Science or related field, or equivalent experience.
  • 5+ years (mid-level) or 10+ years (senior-level) of full-stack software engineering experience.
  • Advanced proficiency in JavaScript/TypeScript and React, including Redux and Context API.
  • Strong experience building APIs with Node.js, Python (FastAPI/Flask), or Java (Spring Boot).
  • Proficiency with Docker - writing Dockerfiles, building hardened images, and integrating with CI/CD pipelines.
  • Familiarity with GitLab CI/CD, Helm, and Kubernetes deployment.
  • Comfortable working in an agile, distributed team environment.
  • Ability to travel up to 5%.

Desired:
  • Experience with data visualization libraries such as D3.js or Recharts.
  • Familiarity with GraphQL federation and advanced API design patterns.
  • Experience with AWS services including ECS/EKS, API Gateway, CloudFront, and RDS.
  • Working knowledge of OAuth2, OIDC, mTLS, and modern API security patterns.
  • Knowledge of the OWASP Top 10 and STIG-compliant development practices.
  • Exposure to Elasticsearch query optimization and index management at scale.
  • Working knowledge of OAuth2, OIDC, mTLS, and modern API security patterns.
  • Knowledge of the OWASP Top 10 and STIG-compliant development practices.
  • Familiarity with RHEL 9 hardening and STIG compliance at the OS and container level.
  • Relevant certifications: AWS Developer Associate, CKAD, or CompTIA Security+.
