The Elastic Search AI Platform, used by more than 50% of the Fortune 500, brings together the precision of search and the intelligence of AI to enable everyone to accelerate the results that matter. By taking advantage of all structured and unstructured data — securing and protecting private information more effectively — Elastic’s complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI.

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

• 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 running penetration tests or vulnerability assessments on web applications, or APIs. Experience as a Red Team operator is also valuable. You should understand the OWASP Top 10 and have some exposure to the OWASP LLM Top 10 or MITRE ATLAS. Additionally, you need to be able to triage findings. You should communicate risks clearly to both technical and non-technical audiences.

• 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.
