The role

Collaborate directly with founders and customers to scope and prioritize work

Contribute to infrastructure decisions and system architecture
What you must have:
Strong experience with TypeScript, React, and Node.js or Python
Comfortable building and deploying production web applications
Ability to move fast and ship iteratively in an early-stage environment
Strong plus:
Experience with data-intensive applications or observability tools
Familiarity with PostgreSQL, ClickHouse, or similar databases

Good instincts for product and user experience
