What is The Role

The Elastic Security Endpoint Protections team researches, designs, and builds the visibility and prevention capabilities at the core of Elastic Defend, our endpoint and SIEM security solution. We are looking for a Senior Security Research Engineer to help lead our efforts to build innovative features that secure our users against the latest emerging threats. You will collaborate with the broader Elastic Security team, a diverse group of skilled researchers, data scientists, and engineers who bring deep domain knowledge in their respective areas. Our geographically dispersed team values positivity and inclusivity in the workplace, clear communication, collaborative learning, and guided mentorship.

We don't just claim our protections work. In recent third-party enterprise protection testing, Elastic Security earned a perfect malware protection score with zero false alarms, the top result in the field. If you have a passion for security research and would enjoy the challenge of devising novel methods for thwarting malicious actors in an ever-evolving threat landscape, join our growing team!

• Research emerging attacker techniques and turn them into shipped protections. Study real-world tradecraft across in-memory threats, injection, credential theft, ransomware, and kernel tampering, then design protections that hold up against an adversary actively trying to defeat them.

• Build and extend endpoint visibility. Instrument new event sources across Windows, macOS, and Linux, deepen the telemetry we already collect, and close the gaps attackers rely on. Every source you add becomes a foundation for other teams.

• Develop production code that runs everywhere. Write performant, stable C/C++ that executes on millions of endpoints, where a memory leak or a few milliseconds of overhead is a customer-visible problem.

• Reverse engineer malware and study evasion. Learn how attackers bypass endpoint security controls in the wild, and feed that understanding directly into the protections you design and harden.

• Own efficacy end to end. Review customer telemetry at fleet scale, investigate false positives and performance regressions, and establish mitigation strategies. Shipping the feature is the beginning of the job, not the end.

• Extend protection parity across platforms. Bring the depth we have on Windows to macOS and Linux, and support new hardware architectures as they reach the enterprise.

• Collaborate across Elastic Security. Implement endpoint code alongside peers in multiple countries and time zones, and work with the detection engineers, malware researchers, and data scientists who rely on your telemetry.

• Help lead the team's technical direction. Take point on initiatives that span multiple releases, raise the bar in design and code reviews, and mentor engineers earlier in their careers.

• Publish and present. Share your research on Elastic Security Labs, present at conferences, and contribute to the open source projects that organizations around
