Description For Founding Engineer (Backend)

About Karsa

At Karsa, we're building the global dollar account—enabling millions of people in emerging markets to protect their savings from currency volatility through stablecoins.

Over 1B people live in economies with severe inflation, losing hundreds of billions of dollars each year in savings, fees, and time spent navigating broken financial systems and black-market exchanges. In these countries, stablecoins offer a lifeline to financial stability.

Karsa allows them to hold dollars and earn steady yield, spend anywhere with a card, and remit money across the world—faster and cheaper than ever before. We've already launched with active users across Pakistan, India, Nigeria, Kenya, and Paraguay, rapidly expanding to additional markets. We're backed by YC and the best investors in our industry, deeply experienced in crypto, and dedicated to providing financial freedom to billions.

As a founding engineer at Karsa, you'll be integral to shaping our product from the ground up. You'll own significant portions of our technical stack and drive critical infrastructure decisions, directly impacting users in some of the world's most economically challenging regions.

This is a unique opportunity to join a mission-driven startup tackling global financial inclusion through innovative blockchain technology. You'll work directly with founders who have deep expertise in crypto and emerging markets, while building systems that directly impact millions of users' financial wellbeing.

The role requires someone who is not just technically skilled, but deeply passionate about financial inclusion and ready to take ownership of major technical decisions. You'll be working in a fast-paced environment where your code directly impacts people's ability to preserve their wealth and access financial services.

We're looking for someone who:

  • Has strong technical skills in backend development and cloud infrastructure
  • Is passionate about financial inclusion and emerging markets
  • Can think like a founder and drive technical direction
  • Is ready to work hard in a fast-paced startup environment
  • Has experience with or strong interest in blockchain/crypto technologies

Join us in building financial infrastructure that matters and makes a real difference in people's lives.
