Sound judgment when using AI tools, including protecting proprietary data, credentials, and customer information and following team security and code-review practices.
Clear written and verbal communication, including the ability to explain technical work to Product and QA.
Ownership and follow-through in resolving issues.
Collaborative approach to reviews and willingness to have one's approach challenged.
