Role description

As a Carbon Specialist, you will leverage your carbon emissions expertise to enhance the cutting-edge carbon models we're forging at Muir, enabling Muir’s core services to more accurately and confidently assess supply chain emissions and identify reductions. You will drive expertise in emissions calculation approaches, models, and data sources, both internally and with customers. You’ll lead research, align methodologies with regulations and customer needs, and foster innovation for evolving landscapes, creating fundamentally new and impactful approaches to measuring and managing Scope 3 emissions. Beyond these key responsibilities, you will also be influential in shaping the norms and culture of the company writ large.


  • Serve as the subject matter expert, internally and externally to customers, on Muir’s approaches, models, and data sources for calculating carbon emissions.

  • Develop and refine predictive models for carbon emissions using data analysis techniques.
  • Ensure the product clearly and effectively communicates emissions and insights to customers.
  • Deeply understand the needs of medium-to-large enterprise customers and tailor solutions to meet and exceed these needs.
  • As an early hire, be able to wear many hats, work quickly and effectively under ambiguity, and play a role in maturing and instilling Muir’s culture.


  • Deep understanding of the carbon emissions calculation landscape, including methodologies, data sources, regulations, scientific standards and customer requirements (e.g. emission factor databases, ISO 14027 / 14067, GHG Protocol, etc.).
  • Proven track record of driving innovation and adapting to evolving regulations, technologies, and data sources.
  • Hands-on experience performing complex carbon accounting calculations (e.g. through product life cycle assessment).
  • Proven ability to lead research, analysis, and documentation of complex methodologies.
  • Experience collaborating with data and software engineers to implement technology.
  • Preference for technical experience developing models and code for emissions calculations.
  • Flexibility and a level of comfort with early-stage ambiguity.
  • Bias for action and ability to iterate are critical.
  • Based in or willing to relocate to the Seattle area.
