Staff Security Engineer - Detection and Response (L4) Location: San Ramon, CA; Reno, NV About Ridgeline Ridgeline is the industry cloud platform for investment management. It was founded by visionary tech entrepreneur Dave Duffield (co-founder of both PeopleSoft and Workday) to apply his successful formula of solving operational business challenges with bold innovation and human connectivity to the unique needs of the investment management industry. Ridgeline started with a clean sheet of paper and a deep bench of experts bound by a set of core values and motivated to revolutionize an industry underserved by its current tech offerings. We are building a new, modern platform in the public cloud, purpose-built for the investment management industry and we are prioritizing security, agility, and usability to empower business like never before. With a growing campus in Reno and offices in New York, Lake Tahoe, and the Bay Area, Ridgeline is proud to have built a fast-growing, people-first company that has been recognized by Fast Company as a "Best Workplace for Innovators," by The Software Report as a "Top 100 Software Company," and by Forbes as one of "America's Best Startup Employers." The Opportunity As a member of the Detections and Response Team (DART) at Ridgeline, you will bring your expertise and new ideas to help develop and execute our Detections and Response roadmap. Acting as a significant architect for the systems overseeing our critical infrastructure - both within AWS and across our broader technical landscape - you will apply your expertise to elevate our collective detection coverage and lead the response to our highest-impact security events. Additionally, in this AI-forward role, you will engineer and validate robust, AI-augmented detection and response pipelines while serving as a key point person to ensure our standards for responsible and fluent AI usage remain relevant and effective. At Ridgeline, the workplace culture is just as important as the products we build. We value ownership, transparency, and a bias toward action - which means we’re always looking for solutions rather than just identifying problems. We’re a team that chooses growth over comfort, owns our setbacks as much as our wins, and thrives on the kind of collaboration that pushes everyone to do their best work. If that’s the environment where you do your best work, we would be interested to meet you. The impact you will have: Shape the DART roadmap based on business priorities and threat models, proactively identifying detection requirements during the design phase of new features and infrastructure. Eliminate detection gaps by performing variant analysis to close entire classes of vulnerabilities rather than addressing individual findings. Architect AI-powered detection and triage pipelines that maintain accuracy and reduce manual effort, minimizing false positives so every alert warrants a response. Collaborate as a key architect for our SIEM, SOAR, and adjacent security platforms, designing scalable, resilient ingestion, enrichment, and alerting frameworks. Own the technical architecture and maturity of our incident response program, guiding the response to complex high-impact events, interfacing with leadership during major incidents, and driving findings to systemic remediation. Set the technical direction for DART-owned codebases and infrastructure, making sound architectural tradeoffs that balance speed, correctness, and maintainability. Establish team standards for the effective and responsible use of AI in detection and response workflows, including appropriate human-in-the-loop guardrails. Influence security strategy across engineering organizations, building consensus with Staff+ engineers through technical credibility instead of unilateral directives. Elevate the team's technical expertise by mentoring junior and mid-level engineers through code reviews, collaborative problem solving
