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 - Network Security to define and implement the network security patterns that keep Nscale’s corporate, OT/BMS, production management, customer management, telemetry, and internet access paths separated, observable, and secure.\nThis role sits at the intersection of security, infrastructure, facilities, IT, platform engineering, security operations, physical security, and third-party providers. You’ll work across data centers, colocation sites, office environments, and production management networks, reviewing designs before hardware and implementation decisions are locked and creating repeatable baselines that support fast deployment in real-world conditions.\nYour work will help Nscale avoid one-off network security decisions at each new site build. By establishing clear trust boundaries, segmentation patterns, and practical standards, you’ll enable the business to move quickly while reducing the risk of corporate networks becoming accidental privileged access zones and ensuring operational networks have the controls they need.\nWhat you'll be doing\nReference architecture and trust boundaries\nDefine data center network security reference architecture across corporate internet access, OT/BMS, production management, customer management, telemetry, and site operations networks.\nEstablish trust-boundary decisions that determine which networks are untrusted, which are privileged, and which flows are explicitly required.\nTranslate network diagrams into trust boundaries, required flows, security controls, monitoring requirements, and risk decisions.\nCreate a clear policy position that corporate site networks provide internet access and do not become privileged access zones by default.\nSegmentation, controls, and secure access\nDesign segmentation patterns, firewall policy principles, routing controls, and network access control requirements for high-risk paths.\nDefine when network access control is required, optional, or unnecessary based on trust zone, user population, asset class, and operational risk.\nPrevent fragile controls such as IP-based trust from replacing strong identity, device posture, application-layer authentication, and explicit authorization.\nSpecify requirements for local safety-critical telemetry paths where latency, availability, or physical operations make remote-only dependencies unacceptable.\nDesign review and deployment standards\nReview new data center, colocation, office, and site network designs before implementation choices are finalized.\nAssess urgent network designs and identify decisions that must be approved, changed, or accepted with compensating controls.\nSet security standards for third-party network providers, installation partners, managed service providers, and data center specialists.\nBuild reusable design checklists, diagrams, and decision records for future site builds.\nTelemetry, monitoring, and cross-functional partnership\nDefine network telemetry, logging, and detection requirements across corporate, OT/BMS, production management, and internet-edge paths.\nPartner with Identity and Security Data to ensure network access depends on strong authentication and produces usable telemetry.\nCollaborate with cross-functional teams to balance security, operational safety, availability, and deployment speed.\nSupport practical security decisions in environments with fast hardware timelines, incomplete designs, and third-party dependencies.\nKPIs\nCurrent-state network trust-boundary map completed\nMinimum security baseline for new data center deployments defined\nUrgent network design reviews completed before implementation lock-in\nUsable network telemetry and logging coverage across key network domains\nAbout You\n7+ years of experience in network security, data center networking, infrastructure security, enterprise network engineering, or related engineering roles\nDeep hands-on experience with routing, switching, segmentation, firewalls, internet edge, WAN, remote access, wireless, and network troubleshooting\nExperience designing or reviewing secure networks across data centers, colocation sites, offices, production environments, or globally distributed infrastructure\nExperience securing OT, BMS, industrial, facilities, or other operational networks where safety, availability, and local control matter\nStrong understanding of zero-trust principles, identity-aware access, least privilege, explicit authorization, and the limits of network location-based trust\nAbility to translate network diagrams into trust boundaries, required flows, security controls, monitoring requirements, and risk decisions\nAbility to work effectively with infrastructure, facilities, IT, platform engineering, security operations, physical security, and third-party providers\nExperience building reusable network security standards, design review processes, and deployment gates\nStrong judgment in real-world environments with incomplete designs, urgent timelines, and complex trust-boundary decisions\nPreferred exposure to AI infrastructure, GPU clusters, high-performance computing, sovereign infrastructure, or hyperscale data center environments\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.
