Senior Software Engineer

The Role

We're building the AI-native infrastructure for tech financing, and we're looking for a Senior Software Engineer who builds with AI, not just around it.

You'll help architect and develop the agentic systems that run our credit risk function - underwriting, risk monitoring, collections, and payments - as complete processes an agent can carry from start to finish, rather than a single feature layered on top of a workflow. You'll work across the stack, with particular depth on the backend: scalable APIs, thoughtful data architecture, and services built to support real financial workflows. You'll also help shape how we build, bringing modern AI-assisted development practices into our everyday work and helping our engineering standards evolve alongside the tools themselves.

This is a role for someone who wants a hand in shaping the product, the architecture, and the way the team works, not just executing what's already been decided.

What You'll Do

• 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.

What We're Looking For

• 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.
• Preferred - experience as a tech lead or team lead, particularly if you grew into that role as a founding or early engineer who helped build something from the ground up.
• 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.

Ideal but not required:

• Experience in FinTech, SaaS B2B, or agentic software for B2B, especially with credit, risk, or payments systems.
• Experience building AI agent-based systems that take autonomous action, rather than generating content or summaries.
• Experience working with backend policies, data flows, and complex business logic.
