We are seeking an experienced Senior Auditor - Finance and Operations to join our Internal Audit function, reporting directly to the Head of Internal Audit. This role is calibrated to Manager-level experience at a Big Four firm, or equivalent internal audit experience in industry: you will independently execute SOX testing and advisory work across several core financial and operational processes - Financial Close & Reporting, Revenue & Billing, Procurement & Payments, Treasury, Payroll, Fixed Assets, Tax, Leases, Equity & Stock Compensation, Sales Commissions, and Inventory - reviewing testing performed by co-sourced or junior team members, as Lambda builds a public-company-ready internal controls environment.

Contribute to the annual SOX scoping and risk assessment process for assigned process areas, in alignment with the overall ICFR program. Maintain ICFR/SOX 404 documentation for assigned processes, including COSO framework mapping, process and control narratives/flowcharts, and risk and controls matrices. Review the testing work of co-sourced resources or junior team members for quality, completeness, and adherence to methodology. Coordinate evidence collection and remediation efforts, holding process owners accountable to agreed timelines. Identify control deficiencies, evaluate severity and root cause, and partner with Finance and busin ess leadership to design and validate effective remediation. Apply professional skepticism to independently evaluate and conclude on control design and operating effectiveness. Operational & Advisory Audits Execute internal audit and advisory projects on operational risk areas beyond core SOX scope - such as revenue/billing reconciliation, vendor and Service Level Agreement (SLA) controls, and contract-related financial risk. Advise Finance, Revenue, Procurement, and Operations process owners on control design for new products, systems, or contract structures. Contribute to components of Lambda’s Enterprise Risk Management (ERM) process, including risk identification, assessment, and prioritization workshops.
