Job Summary

The role is deliberately broad: part trusted advisor part analyst part commercial builder. If you are looking for a narrow well-defined lane inside a large consultancy this is not that. If you want to build something and have your fingerprints on it it is.

About Us:
CEMAsys was founded in Norway in 2007 as one of the Nordics first sustainability advisory and climate technology firms and has spent close to two decades helping complex multi-facility organizations turn fragmented operational data into emissions accounting operational efficiency and real environmental intelligence.

What You Will Do:
  • Own and grow a portfolio of US enterprise clients acting as their senior advisor on strategy operational performance reporting and assurance-readiness.
  • Turn messy operational data into decision-grade analysis that a CFO or COO will act on - energy and resource cost efficiency risk - and work with our product and engineering teams to make that analysis repeatable inside the platform rather than rebuilt in a spreadsheet every year.
  • Translate the regulatory landscape - California SB 253 and SB 261 the state-level rules following California CSRD for US subsidiaries of EU parents ISSB / IFRS S1 and S2 - into practical roadmaps clients can actually execute.
  • Lead GHG inventories across Scope 1 2 and 3 under the GHG Protocol science-based target setting (SBTi) climate risk and scenario analysis and materiality and double materiality assessments.
  • Design and facilitate executive workshops steering committee sessions and client meetings with structure confidence and a clear point of view.
  • Drive business development with our commercial team - scoping proposals pricing and pitching to prospective clients - and own retention and expansion revenue within your portfolio.
  • Handle complex deliveries and challenging client situations with judgment and composure.
  • Mentor consultants earlier in their careers and contribute to our internal methodology quality standards and knowledge base.

What You Bring:
  • 10 years of experience in sustainability climate or ESG - in consulting or in an in-house role with significant advisory and program ownership.
  • Bachelors or Masters degree in sustainability environmental science or engineering business economics finance or a related field.
  • Deep hands-on command of GHG accounting under the GHG Protocol (Scope 3 in particular) California climate disclosure rules CDP SBTi and climate risk and scenario analysis.
  • Strong quantitative and analytical ability - comfortable inside large and imperfect datasets and able to defend the methodology behind the numbers to a CFO or an auditor.
  • A demonstrated track record of owning client relationships and delivering commercial outcomes not only technical deliverables.
  • You use AI tools in your daily work and are comfortable working alongside engineers and agent-based data pipelines - not only in Excel and PowerPoint.
  • Authorized to work in the US without sponsorship based in or relocating to the Boston area and able to travel occasionally to client sites and to our Nordic offices.

Nice to Have:
  • Experience implementing evaluating or working inside ESG software rather than only around it.
