Role Posting Log in to save

As a Senior Security Engineer on the AppSec Foundations team at Datadog, you will design and implement secure-by-default platform controls to enforce production security invariants across distributed systems. Your daily tasks include building scalable security enforcement layers like gateways and policy engines, defining standardized security patterns for broad adoption, integrating security into developer workflows, and identifying recurring risks to drive systemic improvements. You should have experience with software engineering, particularly in Go or Python, and a track record of designing security controls such as authentication, authorization, and API security. Familiarity with modern system handling of identity, communication, and trust boundaries is essential, along with the ability to operate in ambiguous environments and make pragmatic security decisions that balance risk, usability, and scalability.

What you'll do

  • Design and implement secure-by-default platform controls for APIs and services.
  • Build scalable security systems and enforcement layers across distributed infrastructure.
  • Define and standardize security patterns to reduce custom implementations across services.
  • Integrate security controls into developer workflows, infrastructure, and platform abstractions.
  • Identify recurring security risks and translate them into reusable enforced primitives.

What we're looking for

  • Extensive experience in designing and implementing security controls for distributed systems.
  • Strong background in software engineering with expertise in building shared infrastructure used by multiple teams.
  • Proficiency in modern system handling of identity, communication, and trust boundaries (e.g., mTLS).
  • Ability to make pragmatic security decisions balancing risk, usability, and scalability.
  • Experience integrating security into developer workflows and platform abstractions for high adoption.
