As a Security Researcher specializing in AI/LLM Offensive Security, your primary role will involve breaking down, analyzing, and strengthening state-of-the-art reasoning-grade language models. Specifically, your focus will be on identifying and addressing vulnerabilities in leading models such as OpenAI o3, Anthropic Sonnet, Google Gemini, and upcoming models. By collaborating closely with the engineering team, you will work towards mitigating these vulnerabilities effectively. Your key responsibilities will include: - Conducting Red-Team & Exploit Research and Development, which involves designing jailbreaks, indirect prompt injections, and chain-of-thought leaks. You will also be responsible for building fuzzing harnesses and automated exploit suites. - Engaging in Threat Modelling & Framework Alignment by aligning your findings with OWASP LLM Top 10 and MITRE ATLAS standards and integrating them into internal AI RMF playbooks. - Developing Prototype Defences such as prompt firewalls, retrieval guardrails, and fine-tuning strategies. You will leverage advanced approaches like Google's multi-layered red teaming and Anthropics Constitutional Classifiers to enhance security. - Contributing to Community & Disclosure efforts by publishing CVEs and presenting at events like DEF CON AI Village and Red Team Village. - Building AI-for-AI Tooling, including creating autonomous agents that can self-red-team models based on the latest academic research. The required skills for this role include: - Strong proficiency in Python with ML tooling, particularly PyTorch/JAX. - In-depth knowledge of prompt engineering, chain-of-thought reasoning, and their security implications. - Possessing an offensive security mindset with experience in CTF, bug bounty programs, or exploit development. - Fluent in OWASP, MITRE ATLAS, and NIST AI RMF terminology. - Ability to translate complex findings into concise and actionable reports. Bonus points will be awarded for: - Publications on adversarial ML or supply-chain attacks. - Expertise in GPU optimization or fine-tuning large-scale models. - Familiarity with cloud AI security services. - Experience as an open-source maintainer or recognition on platforms like HackTheBox. In return, we offer: - Mentorship from experienced AI red-team professionals. - A remote-first culture with the option of a four-day work week for better work-life balance. - An annual Ship-It budget for attending conferences like DEF CON and Black Hat. - Equity from day one. During the first 90 days in this role, you will be expected to: - Reproduce existing exploits and study current playbooks. - Take ownership of the threat map for a flagship model. - Deliver at least one novel exploit along with its mitigation into production testing. - Share your research through a public technical blog post. To apply for this role, please submit your resume and portfolio. You will also be required to complete a 48-hour async challenge involving jailbreaking our sandboxed model, followed by a pair-programming deep-dive session with the CTO, a culture chat, and finally, an offer.

About the Role Join us in building an autonomous penetration testing platform that simulates real-world adversaries. You'll develop exploit chains, 0-day discovery systems, and evasive payloads that help organizations understand their security posture for cyber insurance and compliance. What You'll Build Exploit Automation : Multi-stage attack chains from initial access to data exfiltration 0-Day Discovery : Intelligent fuzzing infrastructure and vulnerability research systems Evasion Techniques : Polymorphic payloads that bypass modern EDR/AV solutions Cloud Attacks : AWS/Azure/GCP exploitation modules and container escapes Custom C2 : Covert communication channels and post-exploitation frameworks Reporting Engine : Auto-generate compliance-ready pentest reports Technical Skills Required Languages : Python (expert), C/C++, Go/Rust, Assembly basics Web Exploitation : OWASP Top 10 (SQLi, XSS, SSRF, Deserialization, SSTI) Binary Exploitation : Buffer overflows, ROP chains, heap exploitation Tools : Metasploit, Burp Suite, Cobalt Strike, IDA/Ghidra Cloud Security : AWS/Azure misconfigs, Docker/K8s attacks Evasion : AV bypass, sandbox detection, AMSI/ETW patching Must-Have Credentials HackTheBox : Minimum Pro Hacker rank (50+ owns) - include profile link CTF Experience : Active participation (picoCTF, DEF CON quals, GoogleCTF) GitHub Portfolio : Security tools, exploit development, CTF writeups Proven Skills : CVEs, bug bounties, or published exploits are a huge plus Preferred Qualifications TryHackMe Top 5% or PortSwigger Academy completion OSCP/OSWE in progress or completed pwnable.kr, ROP Emporium, or Nightmare challenges Personal security research blog or YouTube channel Contributed to open-source security tools Interview Process Portfolio Review : GitHub + HackTheBox profile assessment Take-Home Challenge : Design an attack chain for given scenario assignment Red Flags We Avoid Only used automated scanners Can't code beyond basic scripts No hands-on exploitation experience Ethical flexibility Green Flags We Love Built your own tools Linux nut Discovered real vulnerabilities Active security community contributor Why This Role? This isn't a typical security internship running Nessus scans. You'll build the platform that makes traditional pentesting obsolete. Your code will simulate real attackers, helping protect thousands of organizations. We need someone who sees a login page and thinks "SQLi, NoSQLi, LDAP injection, or mass assignment?" Someone who gets excited about bypassing protections, not just finding vulns.
