Application Security Engineer

As a Senior Security Engineer within Application Security at Datadog, you will help secure emerging application architectures where established security patterns may not yet exist, including agentic applications, LLM-enabled products, protocol-driven tool use, and untrusted execution environments. You will establish and validate security models, requirements, and controls while partnering with product and platform teams to develop secure-by-default approaches. Your work will address evolving trust boundaries, agent identity, data access, tool permissions, and runtime behavior through threat modeling, security solutions, and practical implementation. You will have the opportunity to shape how Datadog safely supports new application paradigms and address emerging security risks before they become systemic.

At Datadog, we place value in our office culture - the relationships and collaboration it builds and the creativity it brings to the table. We operate as a hybrid workplace to ensure our Datadogs can create a work-life harmony that best fits them.

• Define security models, requirements, and guardrails for emerging application architectures where established patterns are incomplete or do not yet exist.
• Design, implement, and validate practical security controls that reduce risk in emerging architectures and high-risk system behaviors.
• Shape how emerging systems authenticate, authorize actions, isolate workloads, and access data, applying least-privilege principles throughout.
• Partner with product, platform, Infrastructure Security, and other engineering teams to identify security gaps and embed secure-by-default requirements from early design through production.
• Lead threat modeling and security assessments for new and existing products, focusing on evolving threats, unfamiliar trust boundaries, and new interaction patterns.
• Prioritize and drive remediation of emerging security risks, including continuous security testing where it provides durable coverage, and refine security approaches as architectures and threats evolve.

Datadog values people from all walks of life. We know not everyone will meet all the above qualifications on day one. That’s okay. If you’re passionate about technology and want to grow your experience, we encourage you to apply.

Benefits and Growth listed above may vary based on the country of your employment and the nature of your employment with Datadog.
