Competitive candidates will have a track record of writing and shipping quality, well‑documented and well‑tested software. Candidates should be comfortable with modern, cloud‑native computing, and with continuous development and production deployment on cloud platforms to large user populations.
The AI/ML team is built on principles of ownership, accountability, continuous development, and collaboration. We hire for the long term, and we're motivated to make this a great place to work. Our leaders will be committed to your career and development from day one.
