Responsibilities:
Analyze large, complex datasets to identify patterns and trends that could indicate potential security threats.
Collaborate with cybersecurity researchers to understand emerging threats and develop solutions that leverage advanced machine learning and data analytics.
Design, develop, and evaluate ML and LLM-based solutions, including classification, NLP, and security-focused models, from experimentation through production.
Develop and optimize LLM techniques including prompting, retrieval, embeddings, RAG, and fine-tuning where appropriate.
Design robust evaluation methodologies and experiments for classification and LLM-based systems, using appropriate metrics to measure model quality, accuracy, and performance.
Stay up to date with advancements in machine learning, NLP, LLMs, and related technologies, and evaluate their applicability to real-world cybersecurity problems.
Collaborate with software and data engineers to integrate ML and LLM solutions into scalable production systems.
Take ownership of complex data science problems, from problem definition and research through implementation and evaluation.
Requirements:
Bachelor's degree in Computer Science, Engineering, Statistics, Mathematics, or a related field. A Masters or Ph.D. is a plus.
5+ years of hands-on experience in data science, machine learning, or a related field.
Strong understanding of machine learning and deep learning, with hands-on experience developing and evaluating classification models.
Hands-on experience with NLP and text classification, including NER, training and fine-tuning models, and working with both traditional ML and modern LLM-based approaches.
Strong proficiency in Python. Experience with PySpark and Databricks is a plus.
Experience developing and evaluating LLM-based applications, including prompt engineering.
Experience with embeddings, vector search, and vector databases.
Experience working with commercial and open-source LLMs and frameworks, such as OpenAI models and the Hugging Face ecosystem.
Experience with model fine-tuning, RAG systems, and LLM-based classification.
Experience working with highly imbalanced datasets, selecting appropriate evaluation metrics, and optimizing models for precision/recall trade-offs.
Strong analytical and problem-solving skills, with the ability to evaluate and interpret complex data and experimental results.
Excellent communication and collaboration skills, with the ability to work effectively in a multidisciplinary team.
Proven track record of delivering high-quality solutions in a fast-paced, dynamic environment.

Location: Herzliya
Job Type: Full Time
We are hiring a senior individual contributor to join our Data Science team. This is a hands-on role for someone who can take ownership of the full solution, from understanding the problem and building the required data pipelines to developing the model, deploying it, and keeping it reliable in production. You should be comfortable working across data, code, infrastructure, and monitoring independently.
The domain is genuinely hard: noisy sensor and telemetry data, weak and delayed labels, enormous scale, and physical systems that fail in complicated ways. We use whatever technique the problem calls for, from classical machine learning and survival analysis to our own patent-pending deep learning architectures and agentic flows already running in production.
The team moves quickly and operates with a startup mentality: high ownership, short decision paths, and a strong bias toward action. When we encounter a difficult problem, we do not stop at we cant. We ask, How can we?
Moving fast does not mean cutting corners. It means combining resourcefulness and practical judgment with scientific rigor, engineering quality, and production reliability.
We also have proprietary methods for validating results against ground truth, so the feedback loop is real: when a solution works, it ships. You will see your work in production and understand its impact on real fleets.
What youll do
Own projects end to end: stakeholder discussions, problem framing, data exploration, modeling, validation, deployment, and post-launch monitoring.
Turn ambiguous or partially defined business needs into clear, practical, and measurable solutions.
Build predictive and prescriptive models over large-scale vehicle telemetry, diagnostics, and fault data.
Design, build, and maintain scalable, reproducible, and well-tested data pipelines over billions of daily data points.
Build and operate the workflows required for training, validation, inference, and ongoing evaluation.
Take responsibility for getting solutions into production, including automated testing and deployment, environment configuration, monitoring, and troubleshooting.
Choose the right tool for each problem, from gradient boosting and survival analysis to deep architectures over raw signals-and clearly explain your decisions.
Design evaluations that reflect reality, use our proprietary validation methods, and challenge metrics that tell a comfortable but misleading story.
Develop and integrate agentic and LLM-based flows that explain findings, recommend actions, and build the relevant evals.
Investigate failures across data, models, workflows, and production systems.
Present findings, trade-offs, and results clearly to business stakeholders and executive leadership.
Raise the technical bar through reviews, mentorship, and shared standards, as a senior IC, not a people manager.
דרישות:
MSc in Computer Science or an engineering-related quantitative field, such as Electrical Engineering, Statistics, Physics, or Applied Mathematics. A PhD is an advantage.
At least eight years of industry experience in a related data science or machine learning role.
Proven experience taking machine learning solutions to production, not only building prototypes and notebooks, but deploying, monitoring, maintaining, retraining, and troubleshooting what you shipped.
Strong experience building reliable, performant, and well-tested data pipelines over very large datasets.
Strong experience with Spark, distributed computing, SQL, and modern big data platforms. Databricks experience is a significant advantage.
Practical experience with automated testing and deployment, cloud-based systems, workflow orchestration, monitoring, and production troubleshooting.
Experience delivering LLM or agentic applications to production, including evaluation, guardrails, and cost and latency trade-offs.
Strong foundations across statistics, experimental design, classical machine learning, and modern deep learning.# המשרה מיועדת לנשים ולגברים כאחד.
