• Utilize analytical rigor, statistical methods, programming, and data modeling to analyze vast amounts of data, applying your cybersecurity knowledge to guide our focus and approach
• Design and implement LLM-based solutions to face modern cybersecurity challenges
• Decompose complex problems scientifically and provide actionable insights and recommendations to both technical and non-technical stakeholders
• Lead and collaborate on end-to-end projects within the team and across engineering and product teams, from initial ideation to final deployment

Your Experience

• Natural scientific curiosity and ability to handle complex problems
• At least 4 years of experience in hands-on classic data science projects
• At least 2 years of experience in hands-on GenAI projects (preferably LLM) - This includes experience in building or fine-tuning mission-specific generative models, with emphasis on algorithmic design and large-scale deployment
• High proficiency in python and at least good familiarity with SQL
• Advanced degree (MSc or PhD) in Machine Learning, Computer Science, Electrical Engineering, Physics, Statistics, Applied Mathematics, or a related field
• Deep understanding of probability, statistics, and machine learning models with a proven track record of selecting, modifying, and applying advanced algorithms to solve practical problems
• Demonstrated ability to run end-to-end research POCs, from conceptualization to solutions, including designing, executing, analyzing, and concluding research methodologies and outcomes
• Good communication skills, with the ability to convey complex research findings clearly and effectively to both technical and business audiences

Preferred experience

• Background in the cybersecurity domain
• Hands-on experience with open-source generative libraries (e.g., Hugging Face)
• Experience working with big data platforms (e.g., GCP)
• Familiarity with cloud-native architectures and services for data processing

The Team

Our engineering team is at the core of our products and connected directly to the mission of preventing cyberattacks. We are constantly innovating — challenging the way we, and the industry, think about cybersecurity. Our engineers don't shy away from building products to solve problems no one has pursued before.

We define the industry instead of waiting for directions. We need individuals who feel comfortable in ambiguity, excited by the prospect of a challenge, and empowered by the unknown risks facing our everyday lives that are only enabled by a secure digital environment.

Our Commitment

We're problem solvers that take risks and challenge cybersecurity's status quo. It's simple: we can't accomplish our mission without diverse teams innovating, together.
