Prior experience working in early-stage startups or high-growth environments.

Strong proficiency with TypeScript, Node.js , and modern frontend frameworks (React, Tailwind).

Exposure to cloud platforms (AWS / GCP / Azure), containerisation, Kubernetes, and CI / CD pipelines.

Experience with enterprise-grade concerns : secure hosting (VPCs), observability, identity & compliance.

Why Join?

Competitive salary : $200K–$300K + meaningful equity (1%+) in an early-stage company.

Work directly with experienced founders and influence the product roadmap.
