Senior Mobile Security Engineer

The success of PayJoy depends on the strength of its locking technology against various evolving bypass mechanisms. As an experienced Android security analyst and team lead, you will be responsible for both testing and strengthening PayJoy's lock strength directly, and for leading a distributed team of three Lock Product Analysts across Brazil, South Africa, and the Philippines.

We are seeking a highly skilled and tenacious senior analyst with a specialized focus on Android device security. In this critical senior role, you will independently define and lead PayJoy's testing strategy against device lock bypass methods and tools, while also managing and coordinating a distributed team of three Lock Product Analysts across Brazil, South Africa, and the Philippines. Given the problem space — ensuring lock integrity across OS OTA updates, lock technology changes, and evolving in-market bypass tools — you will explore and evaluate your own approaches, propose solutions, and drive them to completion. You will own the vulnerability discovery roadmap, lead the response to what your team finds, and develop the people doing the work.

This position requires 10–25% travel to investigate vulnerabilities and techniques across  several  markets.
