What You Will Do
- Develop and scale end‑to‑end features using TypeScript, React, Node.js, and Postgres, deployed via Kubernetes on Google Cloud Platform.
- Architect and expand a public REST API and real‑time WebSocket infrastructure to support a growing marketplace of third‑party integrations.
- Collaborate deeply with product and design teams to translate complex workforce data models into reliable, AI‑driven automation workflows for global enterprises.
The Ideal Candidate
- Extensive industry experience in full‑stack SaaS development with deep proficiency in Node.js and a strong appreciation for TypeScript.
