Note: This position requires presence in our San Jose or San Francisco office location 4 days per week; Lambda's designated work from home day is currently Tuesday.
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.
What You'll Do- SOX Financial Process Controls & Assurance
- Plan, execute, and document SOX walkthroughs and control design/operating effectiveness testing across assigned financial and operational process areas, exercising independent judgment on complex or ambiguous control questions.
- 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 business 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.
- Control Evaluation & Remediation
- Assess the severity and impact of control deficiencies, including evaluation of aggregation and compensating controls.
- Work with Controllership, FP&A, Revenue, Procurement, and Treasury process owners to develop, track, and validate remediation plans.
- Recommend process improvements and efficiency opportunities while maintaining control effectiveness.
- Stakeholder Collaboration
- Serve as the day-to-day liaison with Finance, Accounting, Procurement, Treasury, and business process owners on SOX and assurance activities for assigned areas.
- Support external auditors during financial-process SOX testing for assigned areas, providing evidence, walkthroughs, and context as needed.
- Provide guidance to process owners, and informal coaching to co-sourced or junior team members, on control requirements and leading practices.
- Reporting & Communication
- Prepare clear workpapers, findings summaries, and status updates for the Head of Internal Audit, including materials to support Audit Committee reporting.
- Communicate control issues and remediation status in clear, business-oriented language to finance and non-finance stakeholders.
- Monitor relevant accounting, regulatory, and industry developments (e.g., revenue recognition, PCAOB guidance) that may affect assigned process areas.
You- Education & Certification
- Bachelor's degree in Accounting, Finance, or related field.
- CPA or CIA strongly preferred.
- Experience
- 8+ years of progressive experience in internal audit, external audit, or accounting/SOX compliance, at a level equivalent to Manager at a Big Four accounting firm, or an internal audit professional with comparable scope and seniority in industry.
- Big Four accounting firm or equivalent experience in Internal or External Audit, including experience reviewing and directing the work of junior staff.
- Deep working knowledge of COSO framework, ICFR, internal audit methodology, and IIA standards.
- Experience independently leading testing of financial close, revenue, procurement, treasury, or other core business-process controls.
- Demonstrated experience in enterprise risk management and operational (non-SOX) audit work.
- Skills & Competencies
- Strong analytical skills, with the ability to independently evaluate financial and operational risk across complex, fast-changing processes.
- Excellent communication and interpersonal skills to effectively engage with, and influence, both finance and non-finance senior stakeholders.
- Proven ability to review and quality-check the work of junior team members or co-sourced resources, even without formal direct reports.
- Organized, detail-oriented, and able to manage multiple concurrent process areas in a dynamic, fast-growth environment with minimal oversight.
Nice to Have- Experience with usage-based, subscription, or long-term/take-or-pay revenue models, and related revenue recognition considerations (e.g., ASC 606).
- Prior experience in a fast-growth or pre-IPO organization, building or scaling a SOX program ahead of public-company readiness.
- Experience with data analytics tools (e.g., SQL, ACL, Power BI, Python) to enhance testing efficiency and insights.
- Experience with audit management tools (e.g., AuditBoard, Archer, Workiva).
- Exposure to data centre, cloud infrastructure, or other capital-intensive business models.
