Data Scientist, Cloudforce One Threat Intelligence

At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code.

We realize people do not fit into neat boxes. We are looking for curious and empathetic individuals who are committed to developing themselves and learning new skills, and we are ready to help you do that. We cannot complete our mission without building a diverse and inclusive team.

Cloudforce One is Cloudflare’s threat operations and research team, responsible for identifying and disrupting cyber threats ranging from sophisticated cyber criminal activity to nation-state sponsored advanced persistent threats (APTs). Cloudforce One works in close partnership with external organizations and internal Cloudflare teams, continuously developing operational tradecraft and expanding ever-growing sources of threat intelligence to enable expedited threat hunting and remediation.

We're seeking a Data Scientist to join our team and drive the analytical rigor behind our cyber threat intelligence efforts. In this highly impactful, hands-on role, you will be instrumental in researching, developing, and applying advanced analytical techniques and statistical models to massive datasets from our global network.

The ideal candidate will possess a strong foundational knowledge of data science principles and statistical modeling. Day-to-day responsibilities include:

• Collaborate with other Data Scientists and Machine Learning Engineers to design and implement analytical approaches that inform scalable threat detection models.
• Partner with threat intelligence analysts to understand emerging attack techniques and leverage data to develop novel detection strategies and expose findings.
• Perform in-depth data analysis to identify trends, relationships, and anomalies within vast security datasets.
• Develop, validate, and refine statistical and machine learning models for threat detection and intelligence generation.
• Monitor the performance of analytical models and threat intelligence pipelines, continuously identifying opportunities for improvement and refinement.
• Investigate and resolve data-related issues in production environments, ensuring the accuracy and integrity of our threat intelligence.

Examples of desirable skills, knowledge, and experience:

• Thorough understanding of statistical modeling, hypothesis testing, and various machine learning algorithms, including their strengths and weaknesses across different data types.
• Desire to see a data-driven project through all the way from initial research and experimentation, through model validation, to the delivery of actionable insights and automated processes.
• Demonstrated ability to present complex analytical findings clearly and concisely, and actively solicit and incorporate feedback.
• Proven ability to deliver high-quality analytical work with strong collaborative and problem-solving behaviors.

Bonus Points

• Experience with large-scale data processing frameworks (e.g., Spark, Flink).
• Experience with time series analysis, anomaly detection, or graph analytics in a security context.
• Proficiency in data visualization tools and techniques to effectively communicate complex findings.
• A basic understanding of the cyber threat landscape and technical Indicators of Compromise (IOCs).
• Experience with Natural Language Processing (NLP) for analyzing unstructured security data.

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.
