  • Contribute to technical documentation and internal tooling.

What We're Looking For
  • Currently pursuing or recently completed a Bachelor's / Master's / Bootcamp degree in Computer Science, Software Engineering, or a related field.
  • Strong programming fundamentals in at least one language such as Python, Java, Go, JavaScript, TypeScript, or C++.

  • Experience building agents that operate in realtime settings
  • Interest in consumer lending, banking, or financial services
What You'll Gain
  • A rare opportunity to contribute to a company that will redefine an entire industry
  • Hands-on experience building software used by real customers.
  • Mentorship from experienced engineers.
  • Exposure to the full software development lifecycle-from planning to production.
  • Opportunities to own meaningful projects and present your work.
  • A collaborative team environment focused on learning, growth, and impact.
