Requirements
- Bachelor's degree or equivalent practical experience.
- 5+ years of professional experience working with TypeScript (React on the front-end, Node.js on the back-end).
- Demonstrated strength on the backend, including designing scalable APIs, databases, and system architecture.
- A track record of building full applications from scratch — modular, full-stack systems, not just features within an existing framework.
- Experience releasing and operating applications in a cloud environment like GCP or AWS.
- Hands-on, everyday fluency with AI development tools such as Claude Code, Cursor, or Copilot.
- A history of helping teams improve their practices and standards, beyond simply completing assigned work.
- Strong ownership mentality and comfort working in a fast-moving, category-creating startup environment.
- Preferred: Experience as a tech lead or team lead.
- Ideal: Experience in FinTech, SaaS B2B, or agentic software, especially with credit, risk, or payments systems.
Responsibilities
- Design and build production systems from the ground up, including scalable backend services, internal and external APIs, and data models that support complex financial workflows.
- Take full-stack features from concept through architecture, front-end implementation, backend logic, and deployment.
- Build and extend AI agent-powered workflows that carry out our credit risk operations, from underwriting and risk monitoring to collections and payments.
- Use modern AI-assisted development tools (such as Claude Code, Cursor, or Copilot) as a natural part of how you build.
- Contribute to evolving our engineering practices and standards, including code review norms, architecture patterns, and how we integrate AI tooling into our workflow.
- Participate in code reviews and offer thoughtful, constructive feedback.
- Collaborate closely with engineers, architects, designers, and product managers to solve complex problems and build products people genuinely enjoy using.
- Bring a spirit of experimentation to your work, while caring about the quality of what reaches production.
