• ML Tooling: Build and enhance infrastructure and tooling for the ML model lifecycle to reduce time-to-market.
• Cloud & Edge Development: Develop and maintain tools for both cloud infrastructure (AWS) and remotely deployed edge systems.
• Code Quality: Write clean, scalable, and well-tested code (primarily Python, with some JavaScript), championing unit, integration, acceptance, and UI testing.
• Deployment Strategy: Support on‑site system commissioning and deployment, prioritizing long‑term automation while handling short‑term manual interventions as required.
• Cross-Functional Collaboration: Work alongside other teams to systematically address technical debt and solve fundamental data challenges.
• Mentorship: Lead code reviews, facilitate design sessions, and actively mentor junior developers to foster a culture of engineering excellence.
• Documentation: Maintain clear, comprehensive documentation of software internals, deployment processes, and development standards.
• Modern Workflows: Leverage generative AI programming tools to automate routine tasks and accelerate engineering velocity.
