• Build a highly scalable web platform based on Python and gRPC that can be deployed in different environments.
• Design and develop interactions with the latest LLMs.
• Contribute to a testing infrastructure that allows us to verify agentic AI behaviours.
• Embrace continuous learning and stay connected with industry best practices, tools, and technologies around AI to drive improvements in our software.
• Provide technical mentorship and guidance to engineers across the Code Creation team and collaborate with other teams
• Influence product and engineering decisions by proposing thorough, iterative solutions to complex technical and architectural challenges
• Collaborate with cross-functional teams across product, engineering, marketing, and more
• Represent the team in technical discussions with customers and stakeholders about AI-powered development capabilities
• Participate in Tier 2 or Tier 3 weekday, weekend, and/or occasional night on-call rotations to assist troubleshooting product operations, security operations, and urgent engineering issues.

What You’ll Bring

• A deep interest in the way AI will change the process of software development
• Multiple years of experience building Python Web Services in a multi-service environment ( e.g. FastAPI, Starlette)
• Proven ability to architect and lead complex technical projects from concept to production across distributed systems
• Strong experience with AI/ML technologies, including integration with large language models and understanding of prompt engineering
• Deep expertise in performance optimization, particularly for systems handling high-volume API requests
• Experience designing and building distributed systems with a focus on reliability, observability, and scalability
• Demonstrated ability to drive technical decisions and influence engineering strategy across multiple teams
• Experience mentoring engineers and raising the technical capabilities of a team
• Excellent written and verbal communication skills for collaborating in a remote, globally distributed environment
• Ability to work effectively across different technology stacks and quickly learn new languages and frameworks as needed
• Experience with the gRPC framework is a plus.
• Experience with languages that our other services use such as Go, Typescript, Ruby or IDE Extension development is a plus.
