Senior Full Stack Developer

About Us

We are a U.S.-based fintech platform founded in 2021, focused on modernizing and digitizing the lending and payments ecosystem.

We operate a multi-lender lending platform and are expanding into payments and financial infrastructure. Our roadmap includes complex underwriting workflows, multi-party application flows, role-based systems, API-driven integrations, and money movement infrastructure.

We’re looking for a Senior Full Stack Developer who thrives in backend-heavy fintech systems and can build scalable, secure, API-driven architecture while supporting front-end development as needed.

If you enjoy solving real-world financial logic problems, integrating third-party services, and building structured systems inside AWS — this role is for you.

• Working with existing design systems and UI structure
  
• Ensuring proper state management and API consumption
  
• Debugging cross-stack issues (frontend ↔ backend)
  
  

System & Infrastructure Responsibilities

• Working within AWS infrastructure (EC2, RDS, S3, IAM, etc.)
  
• Understanding deployment workflows and environment separation (dev / staging / production)

  • ACH/card payment processing logic

• Ensuring compliance-conscious development (data protection, auditability, traceability)
  
• Working with structured underwriting and lender program logic
  
• Supporting webhook-driven external lender responses and state updates

• Experience with GraphQL
  
• Experience building role/permission matrices
