Contract role W2 only

We are seeking a Senior Python Engineer to join our FSD Product Development team. This role is focused on building and maintaining cloud-native, data-driven applications and APIs using Python and AWS.

The ideal candidate is a hands-on senior engineer with deep Python experience and strong knowledge of AWS services, distributed systems, and modern software engineering practices. While the team works with data pipelines and ML-enabled systems, this role is not an MLOps or ML research position. The emphasis is on production-grade software development, scalability, reliability, and performance.

Responsibilities

• Design, build, and maintain scalable, cloud-native services and APIs using Python and AWS.
• Experience with SageMaker
• Collaborate with Product, Architecture, CloudOps, and Engineering teams to deliver reliable solutions that address business requirements.
• Implement backend services using Python frameworks such as Flask, Django, and AsyncIO.
• Build and operate systems using AWS services including Lambda, ECS/Fargate, EKS, S3, RDS, Aurora, Step Functions, and related services.
• Contribute to system and application design, producing clear technical documentation and participating in design reviews.
• Ensure high standards of code quality, test coverage, and maintainability, including writing unit and integration tests.
• Participate in code reviews and provide constructive feedback to peers.
• Identify performance bottlenecks and implement performance tuning and reliability improvements.
• Support integration of data pipelines and downstream consumers (including ML-enabled components where applicable).
• Perform proof-of-concept (POC) work to evaluate new technologies or approaches.
• Work closely with Product teams to translate business requirements into technical solutions.
• Mentor junior engineers and help establish engineering best practices.
• Drive continuous improvement in development workflows, tooling, and system efficiency.

Knowledge, Experience & Qualifications

• Bachelor’s degree in computer science or a related field; Master’s degree preferred.
• 8+ years of experience as a Software Engineer, with a strong focus on Python backend development.
• 5+ years of hands-on experience building and operating applications on AWS.
• Strong experience designing and developing RESTful APIs and microservices.
• Solid understanding of distributed systems, concurrency, system integration, and troubleshooting.
• Experience with AWS services such as Lambda, ECS/Fargate, EKS, S3, RDS, Aurora, and related tooling.
• Hands-on experience with Docker and containerized deployments.
• Experience with CI/CD pipelines, automated testing, and deployment workflows (CodeCommit, CodeDeploy, CodePipeline, Jenkins, Harness, etc.).
• Experience with asynchronous messaging or queueing systems such as Kafka, RabbitMQ, or SQS.
• Experience monitoring and operating production systems, including error handling, logging, and recovery strategies.
• Strong understanding of software development lifecycles and Agile/Scrum methodologies.
• Strong problem-solving, analytical, and debugging skills.
• Excellent communication and documentation skills.
• Comfortable working in a fast-paced, evolving environment with multiple concurrent initiatives.
• Strong team player with experience working with globally distributed teams.
