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 Youll 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 Lambdas 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.

• Prior involvement in ERM program design or risk assessment workshops.

• Experience presenting findings to senior leadership or an Audit Committee.
