You will help shape the technical vision, collaborate with team members, and create impactful LLM-driven applications. This is a unique opportunity to lead groundbreaking developments in AI safety, AI red-teaming, and applied AI deployments that will revolutionize how we interact with AI systems safely. This opportunity is ideal for someone who likes to apply cutting-edge technologies to live cyber-relevant problem sets.

What You’ll Do:

• Work alongside teammates to develop clever, innovative, and efficient solutions to problems in AI safety and cyber detection.

• Co-develop strategies and implementations for end-to-end research and development: data sourcing, data labeling, advanced modeling, evaluation/benchmarking, and product-ready engineering collaboration.

• Interoperate with product and engineering teams to ensure that you are designing and building the right solutions: fit-for-purpose, efficient, computable, and maintainable.

• Drive innovation in LLM-related research and development in close collaboration with security experts.

• Intelligently managed trade-offs between accuracy, efficiency, and operational costs of fielded AI/ML models.

• Make strategic decisions about GenAI model architectures, training approaches, and deployment strategies

• Lead and architect the research strategy for new GenAI agents/LLMs, setting the technical direction for the team

• Drive innovation in LLM applications, including novel approaches to reasoning, summarisation, and interactivity

• Mentor and guide Data Scientists while fostering a culture of engineering excellence

• Lead cross-functional initiatives and collaborate with senior leadership to align technical strategy with business goals

• Represent CrowdStrike's technical excellence through publications, speaking engagements, and thought leadership

• Establish best practices, technical standards, and evaluation frameworks for the team

What You’ll Need:

• Advanced degree (PhD or Masters) in Computer Science, Data Science, or a related field

• 7+ years of applied machine learning / research experience, with demonstrated expertise in developing production-grade models

• Deep expertise in LLM training or post-training / deployment at scale

• Strong technical leadership experience, including mentoring teams and driving technical strategy

• Advanced knowledge of Python, Deep Learning frameworks, and cloud technologies

• Expert-level understanding of GPU technologies and optimisation techniques

• Outstanding communication skills with ability to influence senior stakeholders

• Track record of solving complex technical challenges at scale
