Senior SOX & Internal Auditor

This is an in-person role in the Toronto, Ontario office. Candidates must be based within a 50-mile commuting distance of the office (240 Richmond St W, Toronto, ON) and able to be physically present in the office 4 days a week. 

We are seeking an experienced, technically sophisticated Auditor to lead SOX compliance and internal audit transformation through AI-driven automation. This role is critical to Opendoor's mission of modernizing the control environment for a high-velocity real estate technology platform. You will combine deep SOX/audit expertise with advanced technical capabilities to design, automate, monitor, and optimize controls over financial reporting and operational processes.

This is not a traditional SOX testing role—you will be hands-on building automated controls using SQL, Python, and emerging AI/ML technologies. You'll partner with business owners, data engineering teams, and external auditors to eliminate manual control tasks, implement continuous monitoring, and leverage machine learning for exception detection and control validation.

• Lead and manage SOX 404/302 program execution across business functions, including risk assessments, control design, SOX documentation (flowcharts, narratives, control matrices), control testing, deficiency remediation, and management reporting.
  
• Coordinate with external auditors (Big 4) during quarterly reviews and year-end audits, serving as primary point of contact for walkthroughs, testing support, and remediation discussions.
  
• Execute internal audit engagements covering financial controls, operational processes, IT general controls (ITGCs), and application controls (e.g., NetSuite, Snowflake access controls, data pipeline integrity).
  
• Develop risk-based audit plans aligned with enterprise risk assessments and emerging business priorities.
  

Control Automation & AI Integration

• Design and implement automated controls that replace manual spreadsheet-based processes with SQL-based monitoring queries, Python scripts, and data analytics dashboards.
  
• Partner with business process owners (Accounting, Treasury, HR, Legal, Procurement, Revenue Operations) to identify control pain points and engineer automated solutions.
  
• Build continuous monitoring controls leveraging Snowflake, data build tool (dbt), Airflow, and analytics platforms to detect exceptions in real-time rather than quarterly testing cycles.
  
• Apply AI/ML techniques for anomaly detection, pattern recognition, and predictive control monitoring (e.g., identifying outliers in inventory valuations, unusual transaction patterns, access control violations).
  
• Collaborate with Data Engineering and Analytics teams to integrate control logic into data pipelines and create self-service control dashboards for business owners.
  

Technology & GRC Platform Management

• Work with IT, Data Engineering, and ERP Systems teams to understand system-based controls and implement control monitoring across the technology stack (NetSuite, Ramp, Rippling, Snowflake, Workday, etc.).
  
• Manage GRC platform (Workiva preferred, or similar acceptable) for SOX documentation, test evidence, deficiency tracking, and management reporting.
  
• Drive continuous improvement by recommending efficiency enhancements, automation of manual control activities, and adoption of emerging control technologies.
  
• Stay current on evolving regulations (SEC, PCAOB, COSO), audit standards, and emerging technologies (GenAI, ML-based controls, control automation platforms).
  

Leadership & Stakeholder Management

• Present findings, control maturity assessments, and automation roadmaps to senior leadership including CFO, Corporate Controller, and Audit Committee.
  
• Manage remediation tracking and coordinate cross-functional remediation efforts with process owners.
  
• Mentor and develop junior audit team members on technical skills, automation techniques, and audit methodology.
  
• Translate complex technical and automation concepts into business language for non-technical stakeholders.
  

• At least 3+ years of progressive experience in SOX compliance and internal audit, with at least one (1) year in a public company subject to SEC reporting requirements.
  
• Proven track record of designing and implementing automation in a SOX/audit context—must provide specific examples of automation projects led.
  
• Experience in high-growth technology companies, SaaS, PropTech, FinTech, or high-transaction volume environments strongly preferred.
  
• Direct involvement in Big 4 or similar external audit support, including responding to auditor inquiries, providing evidence, and managing remediation.
• Ability to translate technical automation concepts to business owners, influence process owners, and present to C-level executives.
  
• Ability to operate both at a strategic and tactical level.
  
• Demonstrated ability to lead complex, cross-functional projects.
  
• Proactive learner who stays current on emerging technologies.
  
• Collaborative skills to build strong relationships across functions.
  

Technical Skills Needed

• Proficiency in SQL with the ability to write queries for control testing and monitoring
  
• Python scripting: demonstrated ability to write scripts for data analysis, control automation, and process orchestration.
  
• Data warehouse experience: working knowledge of Snowflake, BigQuery, Redshift, or similar cloud data platforms.
  
• Version control and collaboration: familiarity with Git/GitHub for code-based control documentation.
  
• Understanding of data pipeline orchestration tools (Airflow, dbt, or similar) and how controls integrate into data workflows.
  

Domain Knowledge

• Expert knowledge of internal control frameworks (COSO, COBIT), SOX 404/302 requirements, control testing methodologies, and deficiency assessment.
  
• Strong understanding of PCAOB audit standards (AS 2201, AS 2301) and external auditor expectations.
  
• Familiarity with real estate industry controls (inventory valuation, revenue recognition, transaction processing) or willingness to quickly learn and develop expertise.
  
• Knowledge of financial reporting controls across the financial statement close process.
   

Preferred Qualifications

• Prior experience at a Big 4 accounting firm in IT audit, SOX advisory, or automation/analytics practices.
  
• Experience with ERP systems (NetSuite, Oracle), procurement platforms (Ramp, Coupa), and HR systems (Workday, Rippling).
  
• Hands-on experience building ML models for control monitoring.
  
• Workiva GRC platform expertise.
  
• Knowledge of data governance frameworks and master data management.
  
• Experience with continuous audit methodologies.
