We are Talsec!

A rapidly growing company at the forefront of innovative mobile security. We are part of the Google for Startups community and award winners from Ernst & Young and the Mobile World Congress. Our technology protects hundreds of millions of mobile devices worldwide.

We are looking for a talented iOS Engineer with strong experience in reverse engineering, low-level iOS internals and hands-on knowledge of building non-visual SDKs. If you enjoy exploring how things work under the hood, analyzing app/runtime behavior, and building robust security components, you’ll feel at home here.

What You Will Do:

Develop and enhance our security-focused iOS SDK used in thousands of applications.
Work closely with low-level iOS internals, hooking, binary inspection, obfuscation and anti-tampering techniques.
Apply reverse engineering and runtime analysis to enhance detection mechanisms.
Implement new features improving mobile security for global customers.
Design architecture that is modular, reliable, and hard to bypass.
Collaborate with a small team of experienced security and SDK engineers.

What We Expect from You:

Solid experience with iOS development (Swift/Objective-C).
Proven hands-on experience with reverse engineering, runtime inspection, or understanding of iOS internals.
Experience building frameworks/SDKs (non-UI, system-level components).
Ability to use AI tools (e.g., Cursor) to accelerate development and debugging
Security mindset — ability to think like an attacker.
Proactive problem-solving attitude and independence.

What Is a Plus:

Experience with cryptography.
Knowledge of obfuscation techniques and anti-debugging.
Understanding of low-level concepts like memory layout, linking, Mach-O, code signing.
Familiarity with tools like Frida, Hopper, IDA, LLDB, instrumentation or similar.
Experience with cross-platform security concepts (Android/Windows/Linux).
CI/CD with building frameworks, XCFrameworks, signing, packaging.

What We Offer in Return:

Meaningful Work with Global Impact: Your code will protect applications used by millions every day.
Strong Team: You’ll work with senior engineers experienced in mobile security, RE, and SDK design.
Flexibility & Trust: After an initial onboarding period in our Brno office, you can work in a hybrid model.
Great Gear & Benefits: High-quality hardware, Multisport, educational support, and more.
Space to Innovate: We love experimentation; if you find a smarter solution, we’ll follow it.

If you want to work on real mobile security challenges, understand iOS behavior deeply, and build an SDK that attackers actually try to break, we’d love to meet you.
