À propos
We are seeking a highly motivated and experienced Machine Learning Engineer to join our AI & Threat Analytics team. This is a 100% remote position with an opportunity to work a hybrid schedule for candidates based in the El Dorado Hills, CA or Chicago, IL metro area.
Keeper’s cybersecurity software is trusted by millions of people and thousands of organizations globally. Keeper is published in 23 languages and sold in over 150 countries. Join one of the fastest‑growing cybersecurity companies and play a critical part in advancing Keeper’s AI‑driven threat detection capabilities for our Privileged Access Management (PAM) platform.
About the Role You will tackle one of the most critical challenges in cybersecurity: detecting threats within privileged access sessions with high accuracy and low latency. Privileged accounts are prime targets for attackers, and the ML systems you build will serve as a first line of defense against anomalous and malicious behavior across SSH, RDP, VNC, and database connections. The role focuses on a hybrid detection approach combining vision‑language models (VLMs) and domain‑adapted ML models. You will work in a Python‑based environment processing real‑time session data via WebSocket, WebRTC, and protocol‑level interfaces. The role is well‑suited for engineers who enjoy both research‑oriented work (datasets, evaluation, model training) and applied production engineering (inference systems, integration, and optimization).
Responsibilities
Design, curate, and maintain datasets for training and evaluating threat detection models
Build custom ML models for domain‑specific threat classification and risk assessment
Engineer and optimize prompts for vision‑language models to analyze session behavior
Create evaluation frameworks and benchmarks to measure accuracy, robustness, and reliability
Develop Python‑based inference services within Dockerized environments
Integrate AI/ML capabilities with WebSocket, WebRTC, and low‑level system interfaces for real‑time analysis
Write clean, maintainable code and produce clear technical documentation
Monitor, troubleshoot, and optimize models in production for performance, scalability, and reliability
Requirements
5+ years of professional experience in machine learning research or development
Strong proficiency in Python
Hands‑on experience with dataset collection, curation, and labeling for ML training
Experience designing model evaluation frameworks and performance benchmarks
Experience working with vision‑language models or large language models (e.g., GPT, Claude, Gemini, Qwen)
Familiarity with prompt engineering techniques and LLM frameworks
Experience building and deploying ML inference systems using Docker
Working knowledge of graph data structures and their practical applications
Familiarity with Git‑based workflows and model repositories (e.g., HuggingFace)
Experience using cloud platforms for ML deployment and inference (AWS, GCP, and/or Azure)
Bachelor’s or Master’s degree in Computer Science, Machine Learning, Cybersecurity, or equivalent practical experience
U.S. Person status required due to GovCloud involvement
Preferred Qualifications
Experience with security, fraud, abuse detection, or anomaly detection systems
Familiarity with PAM, identity, or privileged access environments
Exposure to AWS Bedrock or similar managed AI services
Knowledge of network protocols and low‑level system interfaces
