This position is primarily backend-focused but requires strong expertise across the full stack.
What You’ll Do:
✅ Design, develop, and maintain backend services, APIs, and data pipelines that power Knock's customer-facing and internal applications — with occasional frontend contributions to support full-stack delivery when needed.
✅ Architect and build scalable backend services using Node.js and TypeScript that power Knock's customer-facing and internal applications, ensuring they integrate seamlessly with our frontend experiences.
✅ Own end-to-end delivery of complex integration projects, including third-party lending systems and RESTful/RPC APIs, ensuring robust data synchronization, error handling, and seamless service-to-service communication.

✅ Collaborate with engineers, product managers, designers, and business partners to create innovative, impactful technology solutions that deliver excellent user experiences.
✅ Champion best practices in architecture, security, testing, monitoring, and deployment to ensure our applications are scalable, secure, and reliable throughout the development lifecycle.

What You Bring:
- At least 5 years of experience building production-grade software, with at least 3 years writing production-level Node.js code using modern frameworks like Fastify or Express.

Experience with GraphQL is a plus.
- Experience integrating AI/ML services into production applications — such as LLM integration (OpenAI, Anthropic), prompt engineering, or building features that leverage AI for ranking, scoring, or decision support (highly desired).
- Product-minded engineering approach — comfortable working with ambiguous requirements, making pragmatic scope decisions, and designing solutions that truly solve user problems, not just implementing specifications.
- Can contribute to frontend work when needed — comfortable reading and making changes to React/Next.js codebases, even if frontend development isn't your primary focus.
- Database proficiency — solid experience with RDBMS and SQL (MySQL or PostgreSQL), including database design, writing and optimizing queries.
- Solid understanding of software engineering fundamentals and experience across the full development lifecycle — including requirements gathering, development, testing, deployment, instrumentation, monitoring, and ongoing maintenance.
