Software Engineer - Android Firmware

About PayJoy

PayJoy is a mission-first financial service provider dedicated to helping under-served customers in emerging markets to achieve financial stability and success. We lend through our patented technology that turns a smartphone into digital collateral, and our cutting-edge machine learning, data science, and anti-fraud AI allow us to offer the lowest cost and qualify the most customers in the industry. As of 2024 we have brought billions of dollars in credit to 12 million customers, doubling in the last two years while remaining strongly profitable and sustainable for the long term.

This role

As a Software Engineer, you will execute research and development projects to strengthen the lock technology that undergirds our loan products. This is a deep Android environment where the initial emphasis is on the research and subsequent productization of sub-Android techniques for securing devices. 

This role carries high uncertainty, high challenge, and high reward. Stronger locks means more secure loans. More secure loans means we can offer smartphones and credit to as wide an audience as possible. 

This is a dynamic environment. We favor a highly adaptable mindset and believe in breaking through walls. You’ll need a strong dose of independence and persistence, but also collaboration. The initial effort is research-focused, but the intention is to integrate this work into our existing products.
