With several billion app users to protect, now is a fantastic time to join Promon. You'll be part of a vibrant culture and help drive our ambitious plans for the years ahead.

Our headquarters is based in Oslo, Norway, and with our global footprint, we have employees and customers all over the world.

We’re looking for a Security Software Engineer with a passion for systems programming to help evolve Promon’s industry-leading binary protection product. You’ll work with a talented and focused team developing robust, secure, and high-performance tools that safeguard apps from tampering and reverse engineering.

This is a unique opportunity to dive deep into systems-level programming, security, and obfuscation, while building expertise in technologies like Rust and mobile platform internals. If you're ready to go beyond traditional app development and contribute to a product at the forefront of software protection—let’s talk!

Your responsibilities will include:

• Develop and maintain core features of our binary protection product
• Collaborate within a dedicated Scrum team delivering low-level, high-impact security tooling
• Research and evaluate advanced obfuscation and anti-reversing techniques
• Help ensure high test coverage through unit and integration testing pipelines

Preferred Skills and Experience:

• Proficiency in Rust or a strong background in a systems-level language (e.g., C, C++, Go) and an eagerness to learn Rust
• Familiarity with mobile app ecosystems (Android and/or iOS)
• Experience working with reverse engineering tools like Ghidra, IDA Pro, or similar
• A collaborative approach to working in Agile/Scrum teams
• Solid Git skills and experience with hosted platforms like GitHub, GitLab, or Bitbucket
• Comfort working in CI/CD environments and scripting integration workflows
• Familiarity with instruction set architectures and low-level debugging concepts

Bonus Points For Experience With:

• Android NDK or iOS toolchains
• Writing custom obfuscation or binary transformation tools
• Reverse engineering or capture-the-flag (CTF) competitions
• macOS or Linux native development

You’ll be a great fit if this sounds like you:

You enjoy systems-level challenges and have a curious mind that seeks out low-level understanding. You love exploring how things work under the hood—and how to protect them. You’re motivated by impact, excited to collaborate, and always up for learning something new in a fast-moving, agile environment.
