• Debugging production issues and improving system behavior over time

What we’re looking for:

To succeed in this role, you’ll have:

• Practical experience building with AI/LLM technologies, not just using AI tools casually
• Strong Ruby on Rails experience, ideally at a senior level
• Good judgment about when AI is useful and when simpler engineering is better
• Strong backend skills, including databases, API design, performance, background jobs, and security
• Ability to break down ambiguous problems into clear technical solutions
