Customers use our Android and iOS applications daily, so security risks in them affect customers directly. The team works with engineers and other partners across the company to identify and address those risks throughout the application development lifecycle, from secure design and development to stronger protections in the applications customers use.

- Basic knowledge of security concepts and an interest in developing deeper expertise in security.
- Experience defining priorities, coordinating delivery and balancing technical and business needs.
- Experience collaborating with stakeholders across different teams and areas.
- Strong communication skills and proficiency in English.
Preferred qualifications

- Experience with mobile application protections, such as RASP, security signals, obfuscation or anti-tampering controls.
- Experience with security engineering, risk assessments or incident response.

A few links on CyberJobs.cc are referral links: when one leads to a hire, a sign-up or a purchase (a lab, a course or a tool marked Partner), the company behind it may pay CyberJobs.cc a fee. You pay nothing extra, and it never changes the salary an employer offers you or which roles the board lists. Roles from partners who pay us a fee rank a little higher in this list.
