Backend Engineer, Integrations

## About the role Build integrations across the mortgage ecosystem. You'll connect Pylon to external partners — each with their own APIs, data formats, quirks, and reliability characteristics. No two are the same. Work on everything. This role touches every part of the mortgage process. You'll gain a comprehensive understanding of how mortgage works — not in theory, but by building the connective tissue that makes it function. Own solutions from development to deploy to maintenance. You build it, you ship it, you keep it running. Integrations are only as good as their uptime, and that's your responsibility. Be self-directed and versatile. The integrations surface is wide. You'll need to context-switch between partners, prioritize what matters, and drive projects forward without waiting for someone to hand you the next task. Move fast on a high-impact project. This isn't a "someday" initiative. We're building these integrations now, and each one we ship unlocks new capabilities for our customers. ## Tech Stack - TypeScript - NestJS + GraphQL - SQL (PostgreSQL) - Temporal.io (workflow orchestration) - External partner APIs (REST, SOAP, file-based — the full spectrum) - AI-driven development tooling and agentic infrastructure ## Who Will Succeed Here Someone who: - Is deeply curious - Wants to own features from design to development to deployment to maint
