Based in Dartmouth, NS (hybrid) preferred, or Quebec (remote). Toronto, ON (hybrid) will also be considered About CarbonRun CarbonRun is a rapid-growing, venture-backed climate technology company developing river alkalinity enhancement (RAE) projects that improve watershed health while generating high-integrity, durable carbon dioxide removal. We partner with communities, utilities, conservation groups, and governments to restore ecosystems and deliver measurable climate impact. CarbonRun has early commercial projects currently operating and under construction, alongside a pipeline of projects in active development and pre-development across Canada and globally, supported by committed offtakes and capital partners to enable execution and growth. About the Role CarbonRun is hiring a Manager, Supply Chain Operations to lead feedstock sourcing, supplier management, and supply chain operations across our growing portfolio of river alkalinity enhancement (RAE) projects, while supporting project development and management across the portfolio to get projects from ideation to launch. Reporting to the Senior Director, Business Development and working closely with our science, business and operations teams, you will build and maintain CarbonRun's feedstock engagement tracker and supplier network, and support the development and management of projects. This role is ideal for an analytical, detail-oriented operator who is comfortable working across business, supply chain, project development, and technical functions, and who enjoys building processes and relationships from the ground up as part of a distributed, growth-focused team. Key Responsibilities Feedstock Sourcing and Supplier Management Identify, map, and qualify regional feedstock suppliers (e.G., limestone,



suitable industrial byproducts) across CarbonRun's active regions and project pipeline, using research and GIS-based mapping, and assessing chemistry, quality, and supply consistency for RAE application. Own regional feedstock supplier relationships and commercial terms, including negotiating supply agreements and coordinating logistics planning (transport mode, volume, distance), in partnership with the Operations team and in coordination with CarbonRun's science team. Own the global feedstock engagement tracker and supplier map, keeping supplier status and pipeline visibility current, including datasets on feedstock providers and co-location opportunities near priority river systems to support site evaluation. Feedstock Evaluation and Selection Direct feedstock analysis requests and testing programs to assess suitability for RAE deployment, from initial screening through sample sourcing and lab testing. Working with the science and technical teams, ; establish and refine regional-specific thresholds for feedstock purity, particle size distribution, and contaminant metals to streamline supplier qualification and reduce time spent on unsuitable leads. Develop deep working knowledge of feedstock cost dynamics, including pricing, quality, and shipping/logistics tradeoffs across feedstock types and sources, to inform project economics and support pipeline prioritization.



Run scenarios in CarbonRun's TEA model comparing feedstock sources, alternative feedstock types, and shipping/logistics options against cost, environmental footprint, and project economics, using outputs to help prioritize the project pipeline and determine the best-fit feedstock and shipping solution for each project. Support development and maintenance of CarbonRun's life cycle analysis (LCA) models across the project portfolio by providing feedstock and supply chain inputs relevant to project boundaries (Scope 1, 2, and 3) and representative emission factors and Environmental Product Declarations (EPDs). Supply Chain Operations Manage procurement and logistics for non-feedstock materials and equipment (e.G., construction inputs, monitoring equipment, consumables) required across the project portfolio, sourcing vendors and negotiating terms, weighing both cost and environmental footprint. Own transportation and freight logistics across the project portfolio, including carrier relationships, delivery scheduling, and route and mode optimization. Evaluate and design multi-modal supply chain options (rail, marine/bulk carrier, barge, transload terminals) for project sites without local feedstock sources, including total landed cost, transit reliability, and storage/buffering requirements at the destination. Partner with EPC team on the receiving-end storage and handling infrastructure implied by a chosen logistics solution (e.G., silo capacity, transload throughput). Identify supply chain risks, such as single-source dependencies, feedstock or logistics disruptions, and seasonal access constraints, and develop contingency plans and backup sourcing options that
