Attributes We Value
We hire successful builders with founder-like energy who want real impact, accelerated learning, and true ownership. You bring strong role-related expertise and sharp thinking, and you’re motivated by our mission and operating principles. You move fast with good judgment, dig deep with curiosity, and make decisions from first principles, balancing speed and rigor.
You're humble and collaborative; turn zero‑to‑one ideas into real products, and you “get stuff done” end-to-end. You use AI to work smarter and solve problems faster. Here, you’ll tackle complex, high‑visibility problems with exceptional teammates and grow your career as we build the future of global banking. If that sounds like you, let’s build what’s next.
What the Scale Team Does
Embedded Finance Platform: Build and maintain the multi-tenant infrastructure powering companies like Brex, Rippling, Navan, Qantas, and SHEIN. You'll architect systems that aggregate requests from all platform customers, meeting enterprise-grade SLAs for availability, latency, and throughput while handling cross-data-center scenarios.
Cross-Domain Product Features: Own features that require synthesizing knowledge across business, regulatory, and technical domains—areas where no single existing team has full coverage, like tax systems, compliance-driven flows, or monetization tools.
Solutions Architecture: Design integrations for enterprise prospects by translating their business requirements into technical solutions. Your architectural decisions directly influence deal outcomes—from enabling multi-million dollar contracts to differentiating in competitive sales.
