You will serve as the senior-most security engineering point of contact in the region. - Drive Strategy & Architecture: Shape the technical direction of the detection & response engineering function, specifically architecting how global hand-offs and "follow-the-sun" models can be optimized and automated. - Command Security Incidents: Ensure serious threats and impacts are understood, mitigated, and learned from with speed and professionalism, often leading responses end-to-end without immediate escalation paths during local hours — and turning what you learn into durable, automated detections. - Conduct Forensic Investigations & Threat Hunt: Dig into complex context to determine whether threats exist, take decisive action and proactively hunt for anomalous activity in our signals, distinguishing outliers from threats. - Lead High-Profile Responses: Collaborate with Security and Engineering to lead responses to major vulnerabilities or platform-wide events. - Collaborate Cross-Functionally: Work with Legal, HR, Executive teams, and external partners (Developers & Customers). You will also travel semi-regularly to the USA to visit HQ, ensuring deep alignment with central engineering and security leadership. You have: - Experience: 10+ years across security engineering, Infosec, IT, Infra/SRE, and/or Incident Response. - Specialization: 7+ years specifically in Detection or Response, with a track record of building , writing detections, automation or security tooling, not solely operating. - Engineering Proficiency: Comfortable writing and reviewing production-quality code (Scripting) and building automations, integrations and data pipelines that others depend on. - Autonomous Leadership: Proven ability to work independently in satellite offices or distributed teams. You are comfortable being the "person in charge" during your shift and making calls that impact the business. - Incident Command: Extensive experience operating as an incident commander. You can flex into deep engineering work but also possess the executive presence to coordinate responders and communicate status to leadership. - Investigations: Expert-level capability investigating threats in enterprise and production environments, taking ownership from identification to resolution. - Knowledge/Tools/Techniques: Deep understanding of security tooling (SIEM, EDR, IDS/IPS, NDR, SOAR) and experience extending or building on it. You are proficient in applying Incident Response frameworks (NIST IR Lifecycle, Cyber Kill Chain, MITRE ATT&CK) to real-world scenarios, and you collaborate effectively with engineering colleagues, leveraging extensive expertise across infrastructure and technologies (Public Cloud, OS, Virtualization, Containerization, Networking, Build/Development infrastructure, and Hardware). - Education: Bachelor's degree in Computer Science, Cybersecurity, or a related technical field; advanced degree preferred or equivalent experience. You are: - A Builder-Operator: You would rather automate a problem out of existence than staff around it and you hold yourself to an engineering bar even under incident pressure. - A Strategic Self-Starter: You don't wait for instructions. You identify gaps in coverage — especially those unique to regional or time-zone-specific challenges — and fix them. - A Detailed Thinker: You enjoy exploring the details and considering the second- and third-order effects of your decisions. - An Eager Problem Solver: You are drawn to complex issues rather than avoidant of them. - Emboldened to Make Change: You instinctively ask what you can do to improve the situation rather than waiting to be prompted. - Compelled by our Mission: You are driven by the opportunity to protect our community and the safe space we've created. - A Calculated Risk Taker: You move fast, navigating reasonable risks to take action and build capabilities as quickly as possible. Roles that are based in an office are onsite Tuesday, Wednesday, and Thursday, with optional presence on Monday and Friday (unless otherwise noted). Roblox provides equal employment opportunities to all employees and applicants for employment and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local laws.
