Senior Full Stack Engineer

Our client is a mission-driven company building an HR and fintech platform that modernizes employee benefits and enables transparent, trackable social-impact funding.

Tech stack

• Front-end: Next.js + React (PWA), component-driven UI, responsive/mobile-first build

• Back-end: Node.js with Firebase (Auth, Firestore, Cloud Functions), event-driven/serverless patterns

• Infrastructure: AWS / Vercel / Docker (deployments, environments, monitoring/logging as needed)

What you'll build

• A multi-tenant platform supporting employers, employees, vendors, and admins with clean tenant boundaries

• Secure authentication + role-based permissions across all user types (least-privilege by default)

• Wallet / ledger-like flows: transactions, allocations, payouts, and automated fund routing rules
