What This Role Is

• Fast shipping cycles, real users, real stakes
• Ambiguous problems, imperfect data, strong opinions
• Product-engineering hybrid work
• A seat at the table for roadmap decisions

Who You Are

• Strong software engineer who enjoys customer context, not just clean abstractions
• Comfortable shipping quickly and iterating in production
• Excited by ambiguity and building 0 to 1 systems
