Agile delivery with clear roadmaps and shared ownership
Engineers pick up work proactively and take it through completion
Regular feedback, code reviews, and coaching from strong technical leadership
Required Experience
Strong hands‑on experience with React, TypeScript, and Node.js
Full stack experience including backend services and databases
Production AWS experience
Infrastructure as Code experience with Terraform
