Senior Python Full Stack Developers are experienced software engineers who specialize in both frontend and backend web development using Python and related technologies. They are responsible for designing, building, and maintaining complex web applications, often leading teams and making architectural decisions. Their expertise typically includes frameworks like Django or Flask for backend development, as well as JavaScript frameworks such as React or Angular for the frontend. In addition to coding, they often mentor junior developers and ensure best practices in software development. Their role requires a deep understanding of databases, APIs, deployment processes, and modern development workflows.

What are the key skills and qualifications needed to thrive as a senior Python full stack developer?

Familiarity with tools like Django or Flask, RESTful APIs, version control systems (e.g., Git), and cloud platforms is typically required. Excellent problem-solving abilities, effective communication, and the ability to mentor junior developers are standout soft skills for this role. These skills ensure robust, scalable applications and foster effective collaboration across technical teams, driving project success.

Additionally, staying updated with rapidly evolving frameworks and ensuring code quality and scalability across the stack requires continual learning and adaptability. Successful developers proactively bridge these gaps by fostering open dialogue and advocating for best practices throughout the development process.

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+.
