Senior Fastapi information
What is the difference between Senior Fastapi vs Backend Developer?
| Aspect | Senior Fastapi | Backend Developer |
|---|---|---|
| Primary Focus | Building APIs with Fastapi framework | Developing server-side logic across various frameworks |
| Required Skills | Python, Fastapi, async programming, REST API design | Python, multiple frameworks (Django, Flask, Fastapi), database management |
| Work Environment | Tech companies, startups, cloud-based projects | Varied industries, enterprise and startup environments |
| Certifications | Python certifications, Fastapi experience | Python certifications, general backend development certifications |
Senior Fastapi specialists focus specifically on building high-performance APIs using the Fastapi framework, often requiring expertise in async programming and REST API design. Backend Developers have a broader scope, working across multiple frameworks and technologies to develop server-side logic. While both roles require Python skills, Senior Fastapi roles are more specialized, whereas Backend Developers have a wider range of tools and responsibilities.

Job description
Job Summary:
CACI International Inc is seeking a Mid-Senior Full Stack Developer to design and build the primary touchpoint between their platform and its customers. This role involves engineering responsive web applications and architecting an API layer to deliver real-time data while ensuring compliance with government security requirements.
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%.
Preferred:
• 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.
• Familiarity with RHEL 9 hardening and STIG compliance at the OS and container level.
• Relevant certifications: AWS Developer Associate, CKAD, or CompTIA Security+.
