Kitesim is a Hong Kong-founded eSIM and payments company now building out of Kuala Lumpur, operating at the intersection of global connectivity and Web3. We're a small, high-ownership team shipping products used by travelers and businesses worldwide. We run a flat engineering team — no tech lead, no engineering manager. Every engineer works peer-to-peer and reports directly to the founder. Whoever joins will have a real seat at the table on architecture, product, and direction.

The Role

We're looking for a Senior Full-Stack Engineer who treats AI as a force multiplier — someone who can move at 3–5x the speed of a traditional engineer by orchestrating tools like Claude Code, Cursor, and Copilot, while keeping quality and judgment high. You'll own features end-to-end, from database to UI, and ship to production weekly.

What You'll Do

• Build and ship full-stack features across our eSIM platform and payment infrastructure
• Design APIs...
