The Role: AI Security Researcher

We are looking for an AI Security Researcher with a deep understanding of modern LLMs and Generative AI systems, with a strong offensive security mindset. You will focus on breaking, hardening, and securing AI systems, and working closely with engineering teams to design and implement robust AI security solutions.

Key Responsibilities

• Design, execute, and document jailbreaks, prompt injection attacks, model evasion, data exfiltration, and other offensive techniques against chatbots and AI agents.
• Assess and attempt to compromise Model Context Protocol (MCP)–based systems and other tool-calling / plugin ecosystems.
• Build and automate security testing workflows involving multiple LLM models, APIs, and tools (e.g., Jupyter notebooks, orchestration frameworks).
• Perform offensive security testing and red teaming of AI-driven products, including API manipulation and integration abuse.
• Research and analyze security weaknesses in Large Language Models (LLMs), Generative AI systems, and their surrounding infrastructure.
• Contribute to in-house guardrail design: define, implement, and test safety and security guardrails for LLMs and AI automations.
• Propose and evaluate defensive controls: input/output filtering, policy enforcement, monitoring, anomaly detection, and non-AI controls to secure AI systems.
• Translate research findings into practical engineering requirements and collaborate closely with product and engineering teams to implement fixes and mitigations.
• Stay current with the OWASP Top 10 for LLM / GenAI and other emerging AI security standards, frameworks, and threat models.
• Produce clear technical documentation, proof-of-concepts, and internal knowledge sharing on AI security best practices and new attack/defense techniques.

What You'll Need to Succeed

• Bachelors in Computer Science or related degree.
• Experience 2-5 years in offensive cybersecurity.
• Good communication skills in English to communicate security risks to other teams.
• Deep understanding of LLMs and Generative AI (architectures, prompt processing, context windows, system prompts, tool use, fine-tuning, RAG, etc.).
• Hands-on experience with jailbreaking and red-teaming chatbots and AI agents (e.g., prompt injection, role confusion, data leakage, safety bypasses).
• Strong offensive security background: Experience with API security testing and manipulation.
• Prior red teaming, penetration testing, or adversarial testing experience.
• Bug bounty / HackerOne or similar track record is a strong plus.
• Scripting knowledge (Python, PowerShell) and working with no-code flows for automation.
