Job Summary

Job Summary

The Unit42 Managed Services Group is seeking a Senior AI Engineer to architect the next generation of intelligent security operations by developing advanced AI-driven systems that navigate complex investigation lifecycles with unprecedented scale and precision. In this high-autonomy role, you will leverage high-fidelity telemetry and historical datasets to build models that move beyond basic alerting toward sophisticated, automated reasoning. You will be at the forefront of a paradigm shift in cybersecurity, applying state-of-the-art machine learning to some of the most critical data challenges in the industry.

Key Responsibilities

Design and implement autonomous agents using frameworks like LangGraph, CrewAI, or AutoGen to automate complex SOC investigation playbooks.

Build and optimize RAG (Retrieval-Augmented Generation) systems and Vector Databases to provide agents with real-time historical context.

Transition agents from instruction-following to self-learning through LLM Fine-tuning (LoRA/QLoRA) and RLHF based on analyst decisions.

Fine-tune models to understand unstructured telemetry, EDR logs, and network traffic, translating noisy data into actionable security narratives.

Collaborate with SOC teams to codify human intuition into agentic reasoning and robust production deployments.

Develop evaluation loops to rigorously measure agent accuracy and eliminate hallucinations in high-stakes environments.

Qualifications

Required Qualifications

Bachelor's degree with 5 years of experience, or Master's degree with 3 years of experience in a relevant field.

Deep focus and hands-on experience with LLMs, Prompt Engineering, and Agentic Frameworks.

Proficiency in Python and experience handling high-volume data streams (e.g., Spark, Kafka, or Snowflake).

Proven experience building and deploying production-grade AI applications and distributed systems.

Exceptional ability to work cross-functionally with product, architecture, and security research teams.

Preferred Qualifications

Experience with multi-agent systems (e.g., 'Researcher' vs. 'Decision' agent architectures).

Background in traditional Software Engineering (DevOps/CI/CD for ML).

Published research or personal projects in 'AI for Cybersecurity'.

Experience building enterprise SaaS platforms.

Familiarity with the MITRE ATT&CK framework, SIEM/EDR logs, and common attack vectors.
