• Stay up-to-date with the latest AI and software engineering trends and technologies
• Mentor junior engineers: pair on hard problems, review code thoughtfully, and help them level up

• Bachelor’s in CS, engineering, math, physics, or related: demonstrated ability matters more than credential
• 1 - 3 years as a software engineer (strong candidates have shipped something with real users)
• Strong fluency in at least one backend language (Python, Type Script, or similar) and a modern web stack
