• Partner effectively with Product, QA, DevOps, Security, and other engineering teams to ensure smooth delivery of working software into production.
• Champion code quality through thoughtful code reviews, automated testing, documentation, continuous improvement of engineering practices, and sensible use of AI tools for coding, debugging, and prototyping with appropriate human validation.
