Sr. Software Engineer (Node)

Role Summary

The Senior Node Software Engineer is a technically senior, backend-focused individual contributor leading the Node sub-team's technical direction, architecture decisions, and code quality standards, while remaining deeply hands-on in the design, development, and delivery of Evry Health's backend platform. The role centers on building Node.js and TypeScript services, Next.js API routes, and the underlying data layer, bringing a system-level perspective to architecture that considers performance, security, scalability, and healthcare regulatory compliance. Engineers in this role partner with frontend and mobile teams on API contracts but do not own frontend development.

• Backend Architecture & System Design: Leads architecture of the backend platform — service and API structure, asynchronous and real-time processing, rate limiting and resiliency, and relational/document data modeling — documenting decisions for stakeholders.
• Senior-Level Backend Feature Development: Owns design and implementation of the most complex backend features using Node.js and TypeScript, delivering production-quality code that sets the team standard.
• Node.js Services & Next.js API Development: Designs and implements complex Next.js API routes and Node.js backend services — API design and contracts, authentication/authorization, caching, messaging, and relational/document database design and access — enabling frontend and mobile teams to build on stable, well-documented interfaces.
• Technical Leadership & Mentoring: Provides day-to-day technical leadership to the Node sub-team — leading code reviews, mentoring junior engineers, and establishing and enforcing Node coding standards.
• Performance, Testing & CI/CD Ownership: Owns backend performance optimization, testing strategy, and CI/CD pipeline governance, ensuring HIPAA-compliant, secure, and high-availability services.
