You'll work across the entire stack to build products used by banks, credit unions, and lenders every day. From designing intuitive user experiences to building scalable backend systems and AI-powered workflows, you'll own features from idea to production and have a direct impact on our customers.

What You'll Do

• Design, build, and ship full-stack features.
• Own work from concept to production, making thoughtful technical and product decisions along the way.
• Build modern frontend experiences with React, Next.js, and scalable backend services.
• Develop AI-powered workflows, automations, and integrations with the systems our customers rely on.
• Integrate with CRMs, loan origination systems, core banking platforms, and third-party data providers.

• Improve the reliability, performance, and scalability of our platform as we continue to grow.
• Leverage AI tools to move faster while maintaining a high bar for quality / engineering excellence.

• Strong experience with Node, TypeScript, React/Next.js, Postgres, Docker, and K8.
• Experience designing and building APIs, databases, and scalable distributed systems.
• Strong product instincts and the ability to take a half-formed problem and figure out the right shape before someone hands you a spec.
• Excellent communication skills and the ability to work directly with customers.
• Leverage AI tools with opinions about where they help and where they don't.
• Thrive in a fast-paced, high-growth environment with a high degree of ownership.

Benefits & Perks
