Senior Customer Success Manager

Want to be a driving force behind how large enterprises drive decarbonization? How they get from calculation to actual decarbonization? Then this role might be perfect for you!

Our customers are no longer asking whether to measure their emissions, but where to invest to reduce them, and how to explain those choices to management and auditors. This role makes sure that each of our key accounts gets real value from Cozero on that path, and grows with us.

Background & Experience

4+ years in sustainability consulting, Customer Success or Account Management, ideally with enterprise customers.
You have owned renewals or led expansion conversations, not only looked after accounts.
No specific degree required. Solid, applied knowledge of corporate carbon accounting (CCF, PCF) and decarbonisation, and of the regulatory context (CSRD/ESRS, SBTi), matters more than the qualification.

What you will be doing

Strategic

Account plan for every key account: the customer's goals for the next one to two years (targets, reporting duties, reduction plans) and where Cozero fits in.
Strategic business reviews on a regular schedule, with management and finance next to the sustainability team. The focus: how the customer can get more value out of Cozero for their business.
Renewal and expansion: own renewals for your book and prepare upsell together with Climate Solutions and Sales.
Trusted advisor: be a sparring partner for the sustainability lead, not only a point of contact.
Early warning: spot risks (health, stakeholder changes, low usage) and act before they show up at renewal.
Playbook: shape how we do account planning and business reviews, so others can follow.

Day to day

Handle the questions, data quality topics and onboarding steps of your accounts yourself.
Identify where Cozero Act, Cozero Control or our services move a customer forward, and position them proactively.
Bring customer insight back to Product and Climate.
