Job Description:
We are seeking a highly skilled and motivated Applied Data Scientist to join our team. In this role, you will design, build, evaluate, and deploy ML, LLM, and agentic capabilities that improve real-world cybersecurity detection, investigation, and response workflows.
You will work closely with data engineers, software engineers, security researchers, and threat analysts to turn complex security data and attack scenarios into reliable, scalable, and measurable AI-powered product capabilities. This is a hands-on applied role focused on solving practical cybersecurity problems using data science, machine learning, LLMs, agents, and modern AI systems.
Responsibilities:
- Apply machine learning, statistical analysis, LLMs, and agent-assisted techniques to solve practical cybersecurity problems across detection, triage, investigation, and response.
- Analyze large, complex security datasets to identify behavioral patterns, anomalies, attack signals, and trends that can improve threat detection and analyst workflows.
- Translate real-world cybersecurity use cases into data science problems, including problem framing, dataset creation, feature development, model selection, evaluation, and iteration.
- Design, develop, and evaluate ML and LLM powered security workflows, including retrieval, reasoning, tool use, human-in-the-loop review, feedback loops, and guardrails.
- Build evaluation frameworks, metrics, benchmarks, and test datasets to measure model quality, reliability, precision, recall, latency, robustness, and operational impact.
- Develop prompts, instructions, retrieval strategies, and model interaction patterns that improve the usefulness, consistency, and safety of LLM-powered features.
- Partner with software engineers to productionize models, AI agents, and data pipelines in secure, scalable, and maintainable systems.
- Monitor deployed models and workflows for performance drift, data quality issues, false positives, false negatives, and opportunities for continuous improvement.
- Collaborate with cybersecurity researchers, threat analysts, and product stakeholders to ensure AI capabilities address real user needs and evolving threat scenarios.
- Translate relevant advances in ML, LLMs, agentic AI, and cybersecurity into practical product improvements, evaluation methods, and internal best practices.
Requirements:
- Bachelor’s degree in Computer Science, Engineering, Data Science, Statistics, or a related field. A master’s degree is a plus.
- Strong hands-on foundation in machine learning, applied statistics, and data science, including supervised learning, unsupervised learning, anomaly detection, model evaluation, and experimentation.
- 3+ years of experience applying data science or machine learning in production or applied settings. Experience in cybersecurity, fraud, risk, abuse, observability, or other adversarial or high-noise domains is strongly preferred.
- Proficiency in Python and common data science/ML libraries. Experience with PySpark, Databricks, SQL, or large-scale data processing frameworks is a plus.
- Experience working with LLMs in applied or production contexts, including prompt engineering, model selection, evaluation, retrieval-augmented generation, and safe deployment.
- Familiarity with embeddings, vector databases, retrieval systems, and RAG-based workflows for security, knowledge-intensive, or analyst-facing applications.
- Understanding of AI and LLM security considerations, including adversarial inputs, prompt injection, data privacy, model misuse, governance, and safe system design.
- Experience partnering with engineering teams to deploy, monitor, and improve ML models, AI workflows, or data products in production environments.
- Ability to reason under uncertainty, work with noisy and incomplete data, and make pragmatic tradeoffs between model performance, explainability, latency, reliability, and operational value.
- Demonstrated ability to independently frame ambiguous problems, develop, and validate solutions, and drive them from experimentation through production and measurable impact.
- Strong communication and collaboration skills, with the ability to work effectively across security, engineering, data, product, and research teams.

Varonis Compensation & Benefits Highlights
The following summarizes recurring compensation and benefits themes identified from responses generated by popular LLMs to common candidate questions about Varonis and has not been reviewed or approved by Varonis.
-
Healthcare Strength — Healthcare coverage is positioned as comprehensive, including medical, dental, and vision options that start immediately in some locations. The package is frequently characterized as a strong part of the overall rewards offering alongside other core benefits.
-
Retirement Support — Retirement benefits include a 401(k) with company matching (or a pension plan by region), which strengthens the long-term value of the package. Participation is complemented by additional ownership programs that increase total-rewards attractiveness.
-
Equity Value & Accessibility — Equity-related rewards such as stock options and an employee stock purchase plan (ESPP) are a notable part of the total compensation mix. These elements are often cited as helping offset middling perceptions of base pay, especially where equity participation is accessible.
