  • Develop and maintain CI/CD pipelines using GitHub Actions, CDK, and AWS infrastructure (e.g., SageMaker, Lambda, Bedrock)
  • Ensure code quality and reliability through comprehensive unit testing, performance testing, and observability enhancements
  • Collaborate with cross-functional teams to integrate AI services into broader investigation workflows and runtime environments
  • Troubleshoot deployment issues and contribute to the continuous improvement of dashboards and monitoring tools

Required Skills

  • Proficiency in Python and Typescript, with experience in API development and cloud-native architectures
  • Hands-on experience with AWS services including SageMaker, Lambda, etc.
  • Experience with machine learning libraries such as PyTorch, Pandas, NumPy, and related data processing tools
  • Ability to write clean, maintainable code and contribute to shared documentation and best practices
  • Familiarity with GitHub workflows, secrets management, and secure deployment practices
  • Familiarity with Amazon EKS and Kubernetes-based deployments

Preferred Qualifications

  • Experience with GenAI infrastructure, semantic caching, and LLM integration
