Adversarial ML Engineer red-teaming foundation models and AI systems for client security teams.
Investigating vulnerabilities, designing attacks and defenses, and validating remediation across model and agentic layers.
Responsibilities
Conduct hands-on adversarial testing across models, applications, agentic layers, and data pipelines, including multi-turn jailbreaks, guardrail bypasses, prompt injection, agent and tool-chain misuse, dangerous-capability evaluation, API abuse, data poisoning, model inversion, and membership inference.
Investigate edge-case findings from AI red-team campaigns and turn flagged anomalies into understood, reproducible vulnerabilities.
Produce severity-ranked findings mapped to the OWASP Top 10 for LLM Applications, NIST AI Risk Management Framework and Generative AI Profile, MITRE ATLAS, and EU AI Act Article 55 expectations.
Provide evidence and clear reproduction steps for identified vulnerabilities.
Deliver practical remediation guidance and conduct retesting to verify fixes.
Work closely with the client’s Guardrails and AI red-teaming team.
Translate technical findings into clear language for both engineers and non-technical stakeholders.
Remain engaged through remediation and final retesting.
Requirements
Expert-level Python programming with deep proficiency in ML frameworks such as PyTorch, TensorFlow, and Hugging Face Transformers
Hands-on experience fine-tuning ML models and Small Language Models (SLMs), including LoRA/QLoRA, PEFT, instruction tuning, and domain adaptation, for performance and robustness objectives
Strong foundation in ML mathematics: optimization, linear algebra, probability, and statistics
Proven ability to design and execute adversarial attacks, including evasion, data poisoning, model extraction, and membership inference
Experience implementing defenses such as adversarial training, robust fine-tuning, input sanitization, and differential privacy
Proficiency with adversarial ML toolkits such as Adversarial Robustness Toolbox (ART), CleverHans, and Foolbox
Experience red-teaming AI/LLM systems, including prompt injection, jailbreak testing, and safety/alignment evaluation
Ability to evaluate and benchmark model robustness, safety, and security posture before and after fine-tuning
Familiarity with MLOps practices, including model versioning, experiment tracking, and secure deployment pipelines
Strong threat-modeling skills and an attacker’s mindset, with the ability to communicate risks clearly to technical and non-technical stakeholders
Active awareness of the latest adversarial ML and GenAI security research
