AL / ML Lead

Job Description :

Were looking for a skilled Al / ML lead ( 5+ years) based out of Chennai, for a global computer and network security company.

Deep experience in training and fine-tuning Large Language Models (LLMs) such as LLaMA 3 using frameworks like vLLM. The ideal candidate will bring a strong background in machine learning and a practical understanding of the cybersecurity domain - especially around threat intelligence, vulnerabilities, exploits, and configuration analysis.

You will lead the development and implementation of models that understand, process, and generate insights across a wide range of cybersecurity content. You will guide a team of ML engineers and collaborate closely with cybersecurity SMEs, data engineers, and DevOps to ensure delivery of scalable, performant, and security-aware AI systems.

Key Responsibilities :

• Lead the fine-tuning and domain adaptation of open-source LLMs (e.g., LLaMA 3) using frameworks like vLLM, HuggingFace, DeepSpeed, and PEFT techniques.
• Develop data pipelines to ingest, clean, and structure cybersecurity data, including threat intelligence reports, CVEs, exploits, malware analysis, and configuration files.
• Collaborate with cybersecurity analysts to build taxonomy and structured knowledge representations to embed into LLMs.
• Drive the design and execution of evaluation frameworks specific to cybersecurity tasks (e.g., classification, summarization, anomaly detection).
• Own the lifecycle of model development including training, inference optimization, testing, and deployment.
• Provide technical leadership and mentorship to a team of ML engineers and researchers.
• Stay current with advances in LLM architectures, cybersecurity datasets, and AI-based threat detection.
• Advocate for ethical AI use and model robustness, especially given the sensitive nature of cybersecurity data.
