CGI . Position Description We CGI is seeking an experienced backend engineer FastAPI Developer to help a key client deliver critical 2025 milestones. You’ll partner directly with the client’s Principal Engineer from day one, owning the design and build of production-grade APIs and the Terraform infrastructure to run them.

This position can be performed from Lafayette, LA (Preferred), Raleigh, NC, New Brunswick, NJ, New York City, NY, Bloomfield, CT, Dallas, TX, Austin, TX in a Hybrid model. Responsibilities
Design, build, and own FastAPI services in Python 3.x (async-first), including auth, validation, versioning, and documentation (OpenAPI/Swagger). Stand up infrastructure as code with Terraform (modules, workspaces, environments), driving cloud deployments (AWS or Azure preferred). Containerize and ship via Docker; integrate with orchestration and CI/CD (e.g., GitHub Actions/GitLab CI, Kubernetes/ECS/AKS). Implement API security best practices (OAuth2/JWT, secrets management, OWASP), rate limiting, and input validation. Model data and integrate with PostgreSQL/MySQL (SQLAlchemy, Alembic); apply caching (Redis) and performance tuning. Establish observability (structured logging, metrics, tracing; OpenTelemetry) and define SLIs/SLOs. Write comprehensive tests (pytest, contract and load tests using Locust/k6) and participate in code/architecture reviews. Collaborate with the Principal Engineer; lead spikes, de-risk designs, and create clear technical docs and Postman collections. Qualifications
8+ years building backend services in Python, including 3+ years with FastAPI (or Starlette/Flask + recent FastAPI in production). 3+ years with Terraform and cloud (strong in AWS—IAM, VPC, API Gateway/EKS/ECS/Lambda—or Azure—APIM/AKS). Strong async Python, typing (mypy), and Pydantic v2; solid API design fundamentals. Proven track record shipping scalable services end-to-end with CI/CD, containers, and IaC.
