We provide cost-effective, high-performance infrastructure for AI start-ups and large enterprise customers. Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility.\nWe thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As an Nscaler, you’ll build trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you’ll be contributing to building the technology that powers the future.\nAbout the Role\nWe're hiring a Staff Security Engineer to make the data behind Cyber Defense's detections and investigations trustworthy and to uncover threats the team might otherwise miss. This is a hands-on individual contributor role reporting to the Director, Cyber Defense.\nYou'll work across endpoint, identity, cloud, network, vulnerability, SaaS and internal platform telemetry, partnering with the teams that generate the data and with Security Operations, which uses it and provides feedback on alert quality. The work starts with engineering: collecting data completely and making gaps visible. From there, you'll build behavioral baselines and cross-source analyses that become usable detections, not just models or notebooks.\nDefenders need to know when a feed is late, partial or unreliable before they make a decision from it. Your work will make that trust measurable and help them find threats that predefined rules alone may miss.\nWhat you'll be doing\nData inventory and collection\nOwn the inventory of security-relevant sources, including their owners, collection methods, freshness, coverage limits and known gaps.\nBuild and operate idempotent batch and streaming collection from APIs, event streams, object stores and internal systems. Make partial drains, late feeds and schema changes detectable; support backfill and replay.\nDefine consistent identity, asset, time and severity conventions while preserving raw payloads. Document lineage, retention and the limits of what each dataset can support, and handle personal data and secrets deliberately.\nData reliability and quality\nMonitor freshness, volume, completeness, duplicates, schema drift and cross-source consistency. Route quality failures to an owner so analysts know when the data cannot be trusted.\nMake pipeline failures visible, with routine backfill and replay and measured cost per source.\nDistinguish exact figures from lower bounds and unknowns wherever the data is used.\nDetection and investigation\nBuild and evaluate behavioral baselines, anomaly detection and cross-source correlations against investigation outcomes and real alert volume. Work with Security Operations to tune or retire signals that do not earn their place.\nSupport major incidents with defensible scoping, timelines and pattern analysis, turning useful one-off work into repeatable queries or detections.\nPartner with Security Operations to turn analytical findings into signals responders can use and assess against labelled outcomes.\nAI-assisted analysis and collaboration\nPrepare curated, documented datasets for AI-assisted analysis, with scoped and audited access, provenance, freshness signals and safe failure when data is missing or stale.\nHelp detection engineers, analysts and security engineers ask better questions of the data and understand the uncertainty in the answers.\nNegotiate access, schemas and collection cadences with the teams that own source systems, and report coverage gaps back to them.\nKPIs\nShare of security-relevant sources inventoried, collected and documented, with known gaps named\nFreshness and completeness compliance for critical sources, without silent partial drains\nShare of sources with quality alerting to a named owner and time to identify a data defect\nMeasured precision of detections retained by Security Operations and analyst time saved on data wrangling\nAbout You\nYou bring 8+ years in data engineering, data science, detection engineering, security analytics or a related technical field, including significant work with security data.\nYou have built and operated security data pipelines, including collection from APIs and event sources, idempotent loads, partitioning, backfill, replay and schema evolution. You can diagnose the difference between a complete dataset and one that only looks complete.\nYou can work with a cloud warehouse and a streaming system, such as BigQuery and Kafka or equivalents, and you have made data quality measurable and actionable for the people who depend on it.\nYou understand security telemetry across areas such as identity, endpoint, cloud control planes, networks, vulnerabilities and SaaS audit logs, including how attackers can appear in that data.\nYou can apply statistical or machine-learning methods to security analysis, evaluate them against real outcomes and translate the result into a detection that analysts can use.\nYou can work with teams that own the source systems to agree access, schemas and collection cadences, and explain coverage gaps and uncertain findings clearly to analysts, engineers and leaders.\nYou stay hands-on with pipelines, schemas and analysis while building repeatable methods that make the wider team less dependent on one person.\nExperience with multi-tenant cloud or AI infrastructure, graph-based entity resolution, privacy-sensitive data governance, or building data foundations for AI-assisted analysis would be useful, but is not required.\nWhat we can offer you\nAt Nscale, you'll find a collaborative, supportive, and innovative environment where your contributions spark real impact. We're building something extraordinary, and we want you at the core.\nHighly competitive US compensation package (base + bonus + equity), with performance reviews every 12 months. \nJoin one of the fastest-growing AI infrastructure companies - your chance to directly shape how global AI capacity is planned and deployed. \nExpect a dynamic progression plan tailored to your ambitions. Grow by leading critical cross-functional initiatives and shaping capital strategy - always with our full support.\nHuman-First Flexibility: We treat you as humans first. Our flexible workplace trusts Nscalers to deliver, giving you the autonomy to shape your day around life's moments.\nEqual Opportunities Statement\nWe strongly encourage applications from people of color, the LGBTQ+ community, people with disabilities, neurodivergent people, parents, carers, and people from lower socio-economic backgrounds.\nIf there’s anything we can do to accommodate your specific situation, please let us know.\nThe responsibilities outlined in this job description are not exhaustive and are intended to provide a general overview of the position.
