What Are We Looking For?

We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes.

As a Senior Staff Software Engineer in the Detection Platform group, you will be tasked with being the technical authority responsible for defining and evolving the architecture of the cloud-native systems that power our AI SIEM detection, hunting, and response capabilities, including large-scale real-time detection engines, stateful detection engines, anomaly detections, ML pipelines, agentic SOC and threat-hunting capabilities. You will lead the design and execution of backend systems that process billions of events and several petabytes of data daily and serve tens of thousands of security specialists at enterprise and government customers worldwide. Your technical leadership will bridge long-term architectural strategy and high-velocity product delivery, and you will drive cross-team initiatives that shape how detection and response are built and operated across the group.

What Will You Do?

• Architectural Vision: Define and drive the long-term technical roadmap for the Detection Platform group, owning the architecture of the backend systems behind real-time hunting, detection, and response.

• System Design at Scale: Lead the design and implementation of highly available, low-latency, cloud-native services built to process several millions of events per second and petabytes of data, keeping them reliable and performant for the world’s largest enterprises and governments.

• AI-Native Engineering: Embed AI into our services to build agentic threat-hunting capabilities, and reshape how the group builds software by leveraging AI across the development process and raising the bar for how we design, review, and ship.

• Cross-Team Technical Leadership: Drive complex initiatives that span multiple teams to completion, align engineering, product, and design on technical direction, and act as a key stakeholder in cross-organizational architecture reviews.

• Requirements into Architecture: Turn vaguely specified, complex requirements into robust, scalable, operable
