About the project
Our team develops and maintains custom software supporting healthcare operations and clinical workflows. The platform includes backend APIs, system integrations, data-processing services, and AI-enabled applications. Our current applications are primarily written in Python using FastAPI, Pydantic, PyTorch, and medical-imaging libraries.
The platform runs in a containerized AWS environment using services such as Lambda, ECS, SageMaker, API Gateway, S3, SQS, EventBridge, DynamoDB, and CloudWatch. We use Microsoft SQL Server for relational data, Docker for local development and packaging, AWS SAM and CloudFormation for infrastructure as code, and GitHub Actions for CI/CD.
We are expanding our stack by taking ownership of additional applications written in C# and .NET. The role will focus on maintaining and modernizing these applications, developing new capabilities, and integrating them with our existing Python and AWS platform. Reliability, security, observability, and maintainability are key priorities across all our systems.
