  • Excel at making the right level of abstraction—balancing flexibility and simplicity in system/component design.
  • Demonstrate clean communication across technical and non‑technical stakeholders.
  • Make pragmatic decisions on when to optimize for performance versus velocity based on business impact.
  • Thrive in cross‑functional environments spanning Product, Design, Compliance and Sales.
  • Design for scale, maintainability and production excellence.
  • Have led multi‑team initiatives with measurable technical or business impact.

Bonus if you have

  • Fintech, payments or regulated industry experience.
  • High‑scale performance tuning (100k+ QPS, large user bases, strict latency SLAs).
  • Multi‑tenant SaaS or platform architecture background.
  • Proficiency with PostgreSQL, Redis, Kafka or cloud platforms (AWS/GCP/Azure).
  • Experience with OAuth2.0, API design or developer documentation.
  • Cross‑region deployment or data residency compliance experience.
  • Solutions engineering or customer‑facing technical experience.

Why Join Us

  • Build Something That Matters: Your work directly impacts how millions of people use financial services. Companies like Rippling and SHEIN rely on infrastructure you’ll build.
  • Grow Beyond Engineering: You'll develop expertise that extends beyond technical skills—understanding customer business models, navigating regulatory landscapes, influencing enterprise sales.
