  • Establish testing strategies, CI/CD pipelines, and deployment best practices across projects
  • Facilitate technical workshops and stakeholder meetings to align on solutions and deliverables
  • Monitor application performance and lead troubleshooting efforts from both technical and business impact perspectives

Job requirements

  • 5+ years of Python development experience with production-level applications and proven technical leadership
  • Expert-level proficiency in FastAPI including advanced features like dependencies, middleware, and background tasks
  • Advanced Streamlit development skills including custom components, session state management, and performance optimization
  • Deep expertise in LangChain/LangGraph for building and deploying production AI applications
  • Strong understanding of software architecture patterns, design principles, and scalable system design
  • Extensive experience with database design, optimization, and management (PostgreSQL, No SQL, etc.)
  • Proficiency in cloud platforms and deployment strategies with hands-on DevOps experience
  • Experience with containerization (Docker, Kubernetes) and modern development workflows
  • Proven track record in API security, authentication, authorization, and compliance requirements
  • Excellent client-facing and stakeholder management skills
  • Experience leading technical teams or mentoring developers is highly valued
  • Background in consulting or client-services environments is a plus
