Résumé du poste

ByzFunder LLC is seeking a Senior Software Engineer to help build a greenfield AI-native lending platform. You will own features end-to-end, influence architecture, and work with product, operations, and risk teams.

You will integrate AI-assisted tooling, implement REST APIs, work with React/Next.js and Nest.js, and ensure scalable, secure systems that handle the lending lifecycle from origination to servicing.

Qualifications

• 7+ years of professional software engineering experience with strong full-stack capability.

• Strong experience with relational databases (e.g., SQL Server, PostgreSQL, MySQL, AWS RDS) and an ORM (Prisma preferred).
• Experience designing and building REST APIs.
• Experience working with asynchronous processing (queues, background jobs, or event-driven patterns).
• Experience deploying and operating applications in a cloud environment (AWS preferred).
• Solid understanding of application security fundamentals (authentication, authorization, secrets management, audit logging).
• Hands‑on experience using AI-assisted development tools (e.g., Cursor, Claude Code, GitHub Copilot) in day‑to‑day coding, including generating, refining, and validating code.
• Ability to independently take features from requirements to production.

Responsabilités

• Build and ship features across the MCA lending lifecycle — including application intake, document processing, underwriting, offer generation, funding workflows, and portfolio management.
• Contribute to the development of AI agent workflows that automate key business processes and integrate with internal APIs, databases, and data providers.
• Integrate LLM capabilities and MCP servers into ByzFunder's platform for structured access to data sources.
• Follow Spec-Driven Development (SDD) to translate specifications into production-ready code.
• Use AI-assisted development tools as a standard part of daily workflow to move faster while maintaining quality.
• Collaborate with product owners, operations, risk, and compliance to ensure solutions reflect real business needs.
