Sr. Sustainability Specialist within the Global Clean Fuels (GCF) program under Worldwide Operations Sustainability (WWOS). Owns techno-economic and lifecycle assessment modeling for low-carbon fuel pathways, develops and manages a portfolio of technology pilots, and translates technical analysis and pilot results into investment recommendations that drive Amazon's fuel decarbonization strategy across its global transportation network.

Key job responsibilities
Techno-Economic Analysis & Lifecycle Assessment

• Own bottom-up, process-based TEA models for multiple LCF pathways; apply learning rates and scenario analysis across key cost drivers to forecast cost trajectories and inform go/no-go investment decisions
• Conduct lifecycle carbon intensity analyses using established LCA frameworks and carbon accounting standards to guide feedstock and technology selection
• Advance TEA/LCA methodologies and build scalable analytical infrastructure and decision frameworks that grow with the program's fuel volumes, pathways, and geographic scope

Technology Pilot Portfolio Management
Manage a portfolio of concurrent LCF technology pilots across multiple TRL stages:

• Run stage-gate reviews from scoping through pilot to scale-up decision; translate results into updated TEA/LCA projections with go/no-go recommendations
• Coordinate timelines, partner deliverables, and funding across cross-functional stakeholders
• Build scalable playbooks for technology evaluation and pilot management

Feedstock & Supply Analysis

• Model feedstock availability, cost curves, and sustainability across supply chains; evaluate novel feedstocks for CI impact and scalability
• Model delivered costs across geographies to inform deployment sequencing

Program Leadership & Influence

• Advise senior leadership through written narratives (six-pagers, business reviews) and own technical inputs to annual planning
• Build repeatable mechanisms and decision tools that raise the bar across the program
• Mentor sustainability specialists and analysts; participate in hiring and promotion
