## About the role
As an iOS engineer, you will be responsible for improving our scanning engine, for analyzing iOS applications and automatically finding security and privacy issues.
## Responsibilities
- Work with the mobile team on a set of tools we've built to statically analyze IPAs in order to find security issues. We have open-sourced parts of our iOS static analyzer at https://github.com/datatheorem/strongarm.
- Improve our dynamic analyzer, which instruments mobile applications in order to study their behavior while running on a device, and detect dangerous actions that could lead to security issues.
- Research and build new security checks to be added to our scanning engine, so we can help customers build more secure iOS apps.
## Requirements
- Significant experience implementing iOS applications and tools.
- Good understanding of the iOS runtime.
- Some experience writing tools in Python.
## Nice to have
- Experience with taking apart iOS software in order to understand and/or modify it. This includes experience with Objective-C runtime APIs (ie. swizzling) and tools such as CydiaSubstrate, Frida, etc.
- No information security experience required - we are more interested in software engineering backgrounds.
