Python Developer

Senior Python Developer (AWS) Location: Alpharetta, GA, or Princeton, NJ Duration: 12 Months + Reports to: Sr. Director of Architecture and Engineering Job Summary The Senior Python Developer will be a key contributor in building the services that power our unified web architecture. This role focuses on designing and delivering high-quality, cloud-native applications on AWS, using event-driven and serverless patterns. While experience with AWS Chalice is not required, familiarity with it is a strong plus, as many of our services are deployed using Chalice for Lambda-based workflows. The ideal candidate combines strong backend development skills with a passion for scalable, secure, and well-documented solutions. Responsibilities • Design, build, and maintain backend services and microservices in Python, deployed on AWS. • Develop APIs (REST/OpenAPI) and integrate with front-end and partner services. • Implement event-driven workflows using AWS services such as Lambda, SQS/SNS, EventBridge, and Step Functions. • Contribute to ETL and data pipelines, leveraging S3/Parquet, Glue, and Athena where needed. • Work within an Agile/Scrum team, participating in sprint planning, standups, and reviews. • Collaborate with architects and product owners to translate requirements into scalable, testable services. • Write automated tests (unit, integration) and contribute to CI/CD pipelines. • Optimize services for performance, reliability, and cost within a serverless/cloud-native model. • Participate in code reviews, mentor junior developers, and help enforce coding standards. • Document service architecture, APIs, and operational runbooks. Skills • Expert proficiency in Python for backend development. • Strong experience with AWS serverless services (Lambda, Fargate, SQS/SNS, EventBridge, Step Functions, DynamoDB, S3). • Familiarity with AWS Chalice or similar frameworks (Flask/FastAPI with Lambda integration). • Strong knowledge of REST API design and OpenAPI specifications. • Solid understanding of relational databases (Postgres preferred) and ORMs (SQLAlchemy a plus). • Experience with CI/CD pipelines (GitHub Actions, Terraform/CDK familiarity helpful). • Knowledge of observability and logging (OpenTelemetry, CloudWatch). • Strong debugging, performance tuning, and collaboration skills. Experience • Bachelor’s degree in Computer Science or related field (or equivalent experience). • 6+ years of professional backend development in Python. • Hands-on experience with AWS cloud-native/serverless architectures. • Experience building event-driven systems and working with messaging queues. • Prior exposure to Chalice is a plus, but not required. • Background in compliance-driven environments (education, finance, healthcare) preferred. Key Measurements • Delivery of reliable, testable, and well-documented Python services. • Performance, scalability, and cost-efficiency of AWS deployments. • Contribution to migration and integration of legacy systems into unified services. • Team collaboration and mentorship impact. • Positive feedback from stakeholders on delivery speed and quality.
