• Ownership-first mindset — you take initiative, move fast, and figure things out
• Thrive in early-stage, high-urgency environments where speed and impact matter
• Fully committed to working in-person 5 days/week at our SF HQ
• Curious, self-aware, and feedback-driven — you bring energy, not ego
• See this role as a defining chapter — not a stepping stone or side quest
• 5+ years of backend engineering experience, ideally with exposure to high-scale systems.
• Deep experience with modern backend stacks – we use Node.js, ClickHouse and AWS
• Strong understanding of API design principles, query optimization, and distributed systems.
• You’ve worked with large-scale data systems (think TBs of data) and know how to manage performance, cost, and uptime at scale.
• Startup mindset – you move fast, figure things out, and don’t wait to be told what to do.
• Comfortable owning ambiguity – you define the problem, architect the solution, and ship the result.
