About PayJoy
PayJoy is a mission-driven company dedicated to helping a billion people around the world step into the modern financial system for the first time and supporting them on a path to financial success. Founded in 2015, PayJoy’s “secret sauce” technology turns a smartphone into collateral to jumpstart unbanked consumers into the credit system. We reached profitability in 2020, reaching 10 million happy customers and over a billion dollars of sales in 2023.
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.
Responsibilities
- Improve PayJoy’s Android-based locking technology by implementing firmware-level enhancements.
- This role will require intensive development experience and collaboration with the Android SoC/OEM technology stack and ecosystem, and as well with PayJoy’s own MDM solution, PayJoy Access.
Requirements
- Developing ARM-based Hypervisor and Trusted Applications (TA) (5+ years).
- Writing BSP-level code, interfacing with SOCs.
- AOSP and Android firmware development, including interfacing with peripherals.
- Technically communicating in English (written and verbal). Can comfortably create architecture diagrams and documents.
Benefits
- Benefits will change according to the country of hire.
