Vac’s R&D Service Units are integral to supporting IFT (The Institute of Free Technology) projects by researching and developing base components and secure, unbiased protocols.
The Vac Security service unit provides comprehensive support to IFT projects by conducting security audits and helping develop robust security plans. In addition to assisting IFT projects, the security team also supports other IFT services by offering expert guidance on security best practices and risk management strategies. This collaborative approach ensures that all aspects of the IFT ecosystem benefit from enhanced security measures.
By identifying potential vulnerabilities, assessing risks, and implementing effective security solutions tailored to specific needs, the Vac Security service unit plays a crucial role in strengthening the overall security posture of IFT.
We are looking for an Application Security Engineer to join our security service unit. In this role, you’ll perform in-depth reviews of critical code (with a focus on low-level languages like Rust, Nim, and C++), identify both code-level and protocol-level vulnerabilities, and support incident response efforts.
You’ll collaborate closely with development teams to remediate security issues and ensure best practices are followed. You’ll also play a key role in preparing for external security audits—defining audit scope, organising technical documentation, and working directly with auditors to ensure valuable and actionable results.
This is a hands-on position for someone passionate about secure software development and proactive risk mitigation.
