Our culture: We hire talented, self-motivated individuals with extreme ownership and high growth orientation. We value performance and not hours worked. We believe you shouldn't have to miss your family dinner, your kid's school play, friends get-together, or doctor's appointments for the sake of adhering to an arbitrary work schedule. We're a remote-first team spread across time zones, so no office to report to - work from wherever helps you do your best work.

So while we love the "coffee shop today, mountains tomorrow" life, this isn't a passport-optional, work-from-anywhere-on-Earth kind of remote - think flexible within your country, not borderless. Location: Remote - USA or Canada Given the strategic nature of this role, we expect a degree of flexibility for somewhat regular in-person meetings with our leadership team in San Francisco, Berkeley. About the Role You will serve as the technical steward and platform architect for both our Consumer Fraud and Business Fraud engineering teams. This position involves driving technical strategy, optimizing mission-critical infrastructure, mentoring engineers, and assuming broad ownership of a platform that processes massive volumes of data in real-time.
