- You’ve worked at startups previously and navigated ambiguous environments.
- You have a strong product sense and are able to quickly translate customer requirements into technical decisions in our codebase.
- You have a growth mindset, want to constantly improve, and want to receive feedback.
- You're in SF or you're willing to relocate, you love working in-person, and you're serious about joining us to build a culture we will all love
