Lambda, a leader in AI cloud infrastructure serving tens of thousands of customers from researchers to enterprises, is seeking a Senior Auditor for IT Systems and Controls to join its Internal Audit function. This role reports to the Internal Audit Lead and focuses on SOX compliance, IT controls assurance, and internal audit projects. Key responsibilities include planning and executing SOX testing for IT General Controls (ITGCs), IT Automated Controls, and Key Reports across assigned systems. You will conduct walkthroughs and design/effectiveness testing of controls across both homegrown and third-party SaaS applications, exercising independent judgment on complex control questions. The role involves reviewing testing work performed by co-sourced or junior team members for quality and completeness, coordinating evidence collection and remediation efforts, and identifying control deficiencies with root cause analysis. You will maintain ICFR/SOX 404 documentation including COSO framework mapping, process narratives, risk matrices, and testing approaches. Beyond SOX work, you'll execute internal audit and advisory projects focused on IT, data governance, and emerging technology risk, with emphasis on internal controls over financial reporting. This includes evaluating data integrity, system development practices, access management, and change management processes. The role requires strong stakeholder collaboration—serving as the day-to-day contact for IT, Engineering, and Security teams on SOX and assurance activities. You'll support external auditors, provide guidance to IT stakeholders, and coach junior team members on IT control requirements. You'll prepare clear workpapers and status updates for the Internal Audit Lead and Head of Internal Audit, translating technical issues into business-relevant language for non-technical audiences. Required qualifications: Bachelor's degree in Information Systems, Computer Science, Accounting, or related field; 8+ years of progressive IT audit, IT risk, or IT SOX compliance experience at a level equivalent to Manager at a Big Four firm or comparable internal audit professional in industry. CISA certification is strongly preferred; CISSP, CPA, or CIA are a plus. You must have deep expertise in ITGCs, IT Automated Controls, key report testing, and their relevance to ICFR. Experience independently leading audits of both homegrown systems and third-party SaaS applications is essential, along with demonstrated expertise in data governance, system implementation reviews, and cybersecurity risk assessments. Experience with audit management tools (AuditBoard, Archer, Workiva) is required. The position requires presence in the San Jose or San Francisco office 4 days per week, with Tuesday designated as the work-from-home day.
