Core Responsibilities

Primary Functions

Conduct comprehensive Life Cycle Assessments (LCA) to rigorously evaluate the full environmental footprint of products, processes, or services, from cradle to grave.
Design, develop, and implement strategic initiatives for energy efficiency, water conservation, and waste minimization within industrial, commercial, and corporate facilities.
Lead the technical evaluation and project management of renewable energy installations, such as solar PV, wind, and geothermal systems, from initial feasibility studies to final commissioning.
Ensure and maintain strict compliance with all local, national, and international environmental regulations, standards, and reporting frameworks like EPA, ISO 14001, and the GHG Protocol.
Perform detailed energy audits and sophisticated building energy modeling using software (e.g., eQUEST, EnergyPlus) to identify and quantify opportunities for energy reduction.
Collaborate intensively with cross-functional teams, including product design, supply chain, and manufacturing, to embed sustainability and circular economy principles into the entire value chain.
Research, validate, and advocate for the adoption of novel sustainable materials, green building technologies, and cleaner production methodologies to drive down the organization's carbon footprint.
Prepare and present in-depth technical reports, environmental impact assessments, and data-driven sustainability dashboards for diverse audiences, including executive leadership and regulatory agencies.
Champion the certification process for green building standards like LEED, BREEAM, or the Living Building Challenge for new construction and major renovation projects.
Develop and manage complex data models to accurately track, analyze, and report on key sustainability performance indicators (KPIs), such as GHG emissions, water usage, and waste diversion rates.
Actively engage with suppliers and procurement teams to champion sustainable sourcing practices and to evaluate the environmental and social performance of the supply chain.
Serve as the in-house subject matter expert, providing technical guidance and training to other departments on sustainability best practices, environmental management systems, and emerging green technologies.
Analyze and interpret large, complex sets of environmental and operational data to identify underlying trends, forecast future impacts, and inform strategic business decisions.
Manage the technical due diligence and implementation of carbon offsetting projects and the procurement of Renewable Energy Credits (RECs) to meet corporate climate commitments.
Conduct thorough feasibility studies and detailed cost-benefit analyses for proposed sustainability projects, building a robust business case to secure investment and stakeholder buy-in.
Develop and oversee corporate water stewardship programs, which includes conducting water risk assessments, balance calculations, and designing water treatment and recycling systems.
Spearhead or contribute to research and development (R&D) projects focused on creating innovative technological solutions for pollution control, resource recovery, and environmental remediation.
Create and deliver compelling, data-backed presentations to senior management, investors, and external partners to advocate for sustainability programs and report on progress towards public targets.
Perform regular on-site inspections and comprehensive environmental compliance audits to ensure steadfast adherence to operational permits and environmental management plans.
Utilize Geographic Information System (GIS) tools to analyze spatial data for optimal site selection, environmental impact modeling, and natural resource management.
Design and optimize complex systems for waste-to-energy conversion, bioremediation, and industrial effluent treatment to minimize environmental discharges and create value from waste streams.
Maintain an expert-level understanding of the latest advancements in sustainability science, green engineering principles, and evolving environmental policies to ensure the organization remains an industry leader.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to uncover new sustainability insights.
Contribute to the organization's long-term sustainability and climate action strategy and roadmap.
Collaborate with business units to translate high-level sustainability goals into tangible engineering requirements.
Participate in sprint planning, retrospectives, and other agile ceremonies within the engineering and project teams.
