What is The Role

As a Principal Security Research Engineer on the Threat Research and Detection Engineering (TRaDE) team, you'll play a key role in shaping the detection capabilities of Elastic Security. You'll work hands-on with detection engineering and threat research, focusing on enhancing our defenses, particularly in the areas of AI security. This position invites you to apply your solid security background and keen interest in offensive security validating detection methods, helping to create effective and reliable detection content that benefits the wider community.

What You Will Be Doing

• Design and carry out security tests for GenAI applications, agentic systems, and LLM-backed products. These tests will check for various attack types. They include prompt injection, indirect injection, retrieval poisoning, tool misuse, sensitive data extraction, and unsafe delegation to with the core purpose of building security protections

• Investigate new multi-domain threat vectors and attack methodologies to stay ahead of emerging risks and translating these into new security protections (e.g. detection rules)

• Create and present findings to enhance team knowledge and community awareness

• Apply AI-assisted techniques to expand coverage and accelerate validation. This may include developing new capabilities and Elastic AI workflows to streamline our threat research and detection engineering processes

What You Bring

• You should have experience working with endpoint data and understand detection engineering GenAI pitfalls working with existing telemetry

• You should have hands-on experience using LLM tools for security testing, research, or daily tasks. You need to understand how LLMs work. This includes context windows, tool use, RAG, and agentic chaining. Knowledge of AI testing tools or frameworks, such as Garak, PyRIT, PromptBench, Inspect AI, or similar (including personal research or experiments) is a plus.

• You should have experience using AI-assisted development tools and modern AI/ML frameworks. These tools help you accelerate up feature development. They also help you debug complex systems and optimize existing codebases. You will generate telemetry, conduct threat research, and assist with detection engineering workflows.

• Proven ability to seamlessly transition between different projects, codebases, or scrum teams based on dynamic business priorities.

• You work autonomously and can drive decisions and results in a distributed team by leveraging asynchronous, direct, and transparent communication.

• Previous successes in presenting findings and insights to technical audiences
