What You Bring

• 5+ years of experience building and shipping production software
• Proven success shipping code used at scale (1M+ consumer users or 100k+ enterprise users)
• Strong CS fundamentals (you can reason clearly about system design, data structures, and algorithms)
• Experience working in large codebases and building developer tooling
• Working knowledge of databases at scale and integrating third-party APIs
• Fluency with agentic coding tools and a track record of producing quality work quickly with them
• Excellent communication and collaboration skills, and enthusiasm for in-person, whiteboard-heavy design work at the early stages of product development

Additional Experience That's Useful

• Experience at a Series B/C startup or scale-up
• A CS degree from a strong program, or engineering experience at a company with a high technical hiring bar (e.g. Google)
• Good taste in developer-friendly UX

• A collaborative team culture
• Opportunities for growth and learning
• Meaningful work with world-class companies
