Job Description 

Swift Tech Co. builds custom software and platform infrastructure across FinTech, logistics, and SaaS engagements, production systems handling real money and real operations, not prototypes. We're looking for a senior backend engineer to own core services for a logistics client's scheduling platform, one of several concurrent systems on your plate, with real architectural authority from day one.

Responsibilities 

  • Design and maintain high-throughput services in Node.js (Express/Fastify) with PostgreSQL and Redis, serving live client traffic
  • Design and evolve REST and GraphQL APIs consumed by our own frontend team and by client-side integrators directly
  • Lead technical design reviews for client scheduling and routing systems, including tradeoff docs the client's own engineers can read
  • Implement authentication and authorization (JWT/OAuth 2.0, role-based access) for multi-tenant client systems
  • Mentor two mid-level engineers through code review, pairing, and structured 1:1s
  • Own on-call rotation and incident response for services you ship, from paging to postmortem
  • Partner directly with client stakeholders during discovery to scope technically sound solutions before implementation starts
