  • Require a product mindset and customer orientation.
  • Prefer experience building agentic systems in fintech or other regulated industries.
  • Prefer founding-engineer or early technical-contributor experience in high-growth environments.
  • Prefer demonstrated ability to ship technically complex systems in regulated contexts and meaningful open-source contributions, particularly in AI or developer tooling.

Benefits

  • Comprehensive medical, dental, vision, life insurance, and disability benefits.
  • Flexible working model with hybrid, onsite, or virtual arrangements depending on role and business need.
