Software Engineer - Security Agent

3+ months agoParis, France / Remote

About Datadog:

We're on a mission to build the best platform in the world for engineers to understand and scale their systems, applications, and teams.  We operate at high scale—trillions of data points per day—providing always-on alerting, metrics visualization, logs, and application tracing for tens of thousands of companies. Our engineering culture values pragmatism, honesty, and simplicity to solve hard problems the right way.


The Opportunity:

The Security Agent team develops innovative ways to protect customers, detecting (even blocking) attacks and threats at runtime on the servers themselves. Unauthorized file changes, bad processes, suspicious network communications, dangerous kernel changes… There’s no shortage of risks to protect against. Doing it at runtime on the production servers of thousands of our customers, with no visible performance impact and no stability risk, is a tall order. In a given day, you may dive into low-level Linux internals, move past the many obstacles through careful thinking and open discussion in the team, find and fix the (possibly unusual and imaginative) bypasses of our security features...


You Will:

  • Develop (in Go and C/eBPF) the Security Agent in the open, adding new security detections capabilities as well as strengthening the existing ones.
  • Keep ahead of Linux’s most recent additions like KRSI, yet bring new features to older kernels.
  • Join a tightly knit team solving hard problems the right way.



  • You have a BS/MS/PhD in a scientific field or equivalent experience.
  • You have mastered Linux, from the system to the libs to the common apps.
  • You are comfortable with low-level implementation and systems programming (e.g. syscalls, network, kernel modules).
  • You care about code simplicity and performance.
  • You want to work in a fast, high growth startup environment that respects its engineers and customers.


Bonus Points:

  • You enjoy interacting with the upstream open-source communities, and can drive technical conversations in the open.
  • You enjoy sharing with great docs or blog posts.
  • You are interested in security.
