This role offers the chance to drive immediate impact for global enterprise clients within a rapidly scaling, well-funded Series A startup environment.

• Join a well-funded Series A startup backed by top-tier VCs, offering meaningful early-stage equity and potential for wealth creation.
• High-impact environment where you ship weekly and see your features used by thousands of reps at the world's largest enterprises.

What You Will Do

• Build and scale features end-to-end using Next.js, React, Node.js, and TypeScript across both PostgreSQL and MongoDB.

• Partner directly with the founding team to scope product features and iterate rapidly based on direct customer feedback.

The ideal candidate

• Proven experience shipping production-grade code in fast-moving, high-growth environments or as a previous startup founder.
• Expertise across the modern TypeScript stack with the ability to diagnose and fix architectural root causes independently.
