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? Primary responsibilities include: 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 end-to-end designs that fit the overall data architecture, and define the coding patterns and standards other teams build on. Operational Excellence: Champion engineering best practices across the group, including observability, performance optimization, and data integrity, and safeguard application stability by owning the key metrics, diagnostics, and incident-response processes that matter. Mentorship & Growth: Elevate the engineering bar as a recognized subject-matter expert whose input others seek out, mentoring other software engineers in the group and fostering a culture of technical excellence and accountability.   What Skills and Knowledge Will You Bring? Ideal candidates will have: 10+ years of software engineering experience with deep production-level mastery of Go and/or Java (Python a plus), and a strong track record of building and operating high-scale distributed backend services. A track record of being a recognized subject-matter expert others seek out to review and elevate their designs, with a passion for building high-scale distributed systems. Platform thinking: proven experience building and evolving platforms, not just features, with a focus on API design (gRPC, REST), service boundaries, multi-tenancy, and shared infrastructure in a high-sc
