About the Role

We are looking for a Security Engineer with a strong technical background to join our global Red Team. This is a role for a "Builder-Breaker"—someone who understands that modern offensive security requires more than just running tools; it requires building them. Working alongside world-class AI Cybersecurity experts, you will research and develop new attack techniques, integrating them directly into our proprietary Offensive SDK. You will spend a significant portion of your time in Visual Studio, translating offensive research into production-ready code.

Responsibilities

• Offensive Research & Implementation: Investigate and prototype new attack techniques and TTPs, focusing on the intersection of traditional infrastructure and AI systems.
• SDK Contribution: Develop and maintain modules for our internal Offensive SDK, ensuring our team has custom, stealthy tools for every engagement.
• Adversary Simulation: Execute end-to-end Red Team engagements, simulating real-world adversaries to test and improve client defenses.
• Active Evasion: Design and implement custom code to bypass modern security controls (EDR/XDR) and behavioral detection engines.
• Collaborative Learning: Share findings with the broader AI Security team to refine our defensive and offensive capabilities.

Qualifications

• Experience: 3 to 5 years of experience in offensive security (Red Teaming, Advanced Pentesting) or security-focused software development.
• Technical Education: A Bachelor’s degree in Computer Science, Software Engineering, or a related technical field. A solid foundation in engineering principles is essential.
• Visual Studio Proficiency: Strong hands-on experience in a professional development environment. You must be comfortable managing projects, debugging, and compiling code within Visual Studio.
• Offensive Mindset: Proven ability to research system internals and develop custom exploits, payloads, or bypasses.
• Problem Solver: A proactive approach to technical challenges—you prefer building a solution rather than waiting for a patch.
• Language: Fluent English for a global, international working environment.

Preferred Skills

• Familiarity with Windows/Linux APIs and low-level system concepts.
• Certifications such as OSCP, OSEP, or CRTO.
• Contributions to open-source security tools or community research.

What We Offer

• Competitive salary aligned with your experience and impact.
• Work alongside a high-performing, international team.
• Hybrid setup in Barcelona, fostering strong collaboration.
• Flexible Compensation (COBEE): Access to a Cobee card to manage tax-free benefits, including: Restaurant/Meals, Public Transport and Daycare.
• Exposure to cutting-edge AI and enterprise-scale deployments.
• Be part of one of the most exciting AI startups in Europe.
