Core Responsibilities:

Assurance Program Leadership and Operations

Manage day-to-day operations of the GHG/ESG assurance function and execute department strategies to achieve agreed key performance metrics.
Build, maintain, and continuously improve an assurance methodology, including engagement acceptance, independence and conflict checks, scoping, risk assessment, materiality, evidence planning, sampling, review, issue resolution, documentation, and statement issuance.
Establish repeatable templates, workpapers, review protocols, records-retention practices, and quality-control checkpoints that support consistent, audit-ready delivery.
Plan the engagement portfolio, assign resources based on competence and independence, monitor capacity, and surface delivery, quality, budget, or client risks early.
Define and monitor program measures such as on-time delivery, budget performance, review findings, rework, client feedback, staff utilization, and corrective-action closure.
Maintain awareness of relevant assurance, GHG accounting, sustainability reporting, and regulatory developments; translate changes into practical updates to methods, training, and client guidance.

Engagement Delivery and Technical Oversight

Lead and review GHG and ESG assurance engagements from discovery and proposal development through planning, fieldwork, reporting, and closeout.
Scope work, estimate effort, develop workplans and budgets, identify required expertise, and document the criteria, organizational and operational boundaries, intended users, level and type of assurance, materiality, and deliverables.

Review workpapers and client-ready deliverables for accuracy, completeness, traceability, consistency, and clear communication of findings, conclusions, recommendations, and limitations.
Prepare, review, and when authorized, approve or sign assurance statements in accordance with applicable standards, licensing requirements, and internal authority protocols.
Maintain clear separation between advisory support and independent assurance activities, escalating independence, ethics, quality, or scope concerns promptly.

Coach team members in assurance concepts, GHG/ESG technical topics, project management, client communication, documentation, and quality review.

Client, Commercial, and Cross-Functional Leadership

Build trusted relationships with senior client stakeholders while maintaining objectivity, confidentiality, and appropriate assurance boundaries.
Facilitate discovery, planning, status, issue-resolution, and closeout discussions; communicate technical matters in clear, practical language.
Contribute to proposals, statements of work, pricing assumptions, presentations, and solution development for assurance and assurance-readiness services.
Collaborate across sustainability, energy, engineering, procurement, data, and compliance teams to coordinate expertise and deliver integrated client outcomes.
