Munich or Madrid Workplace type: Hybrid (3 days per week in office) A carbon onboarding succeeds or fails on decisions taken in the first three weeks: system boundaries, which Scope 3 categories are in, where primary data is worth collecting and where a factor will do. This role takes our large and complex Carbon customers live with those decisions made well. You lead customers rather than serve them: you decide the sequence, push back on scope that does not serve the go-live, and leave the team better than you found it. What you will own
* Run complex onboardings end to end. Scoping, configuration, data integration, key-user training, go-live and a documented handover to Customer Success — for our largest and most complex accounts.
* Own effort and budget. Estimate realistically, stay inside the booked hours, and when you see overconsumption coming, trigger the follow-up sale with CS and Sales instead of quietly continuing to deliver.
* Make the next project cheaper. Build onboarding packages, checklists and self-service content (an eLearning instead of a session) for the standard use cases in your area, and use the Solution Expert's enablement material consistently.
* Coach the team. Review project plans and configurations from more junior consultants, step in on difficult customer situations, and give the feedback that feeds the skill matrix.
* Work with the Solution Expert. Escalate genuine edge cases, and play patterns back — recurring questions, product gaps. You are not a stand-in Solution Expert.




* Build the customer relationship with decision-makers during the onboarding and hand it over to CS with the stakeholder map documented. Roughly how the role splits: 70 % your own customer onboardings
· 15 % coaching and review
· 10 % standardisation
· 5 % collaboration with the Solution Expert. What you bring
* Several years of project experience in SaaS implementation or consulting in carbon accounting or sustainability reporting — with full responsibility for the customer, not just a workstream.
* Practical GHG accounting knowledge: GHG Protocol, Scope 1–3, emission factor selection, and the difference between a defensible footprint and a fast one.
* Familiarity with the reporting context — CSRD / ESRS E1, and ideally CBAM or product carbon footprints.
* Solid understanding of data models, interfaces and configuration — no coding required. Experience integrating ERP, energy or logistics data is a strong plus.
* The instinct to standardise. You notice when you are doing the same thing for the third time and turn it into a package.
* Budget and scope discipline: you state the limits of the engagement clearly to the customer rather than absorbing scope creep.
* Languages: fluent English. German or Spanish is a plus
* Some travel — below 10 %; onboardings run largelyremote. Join us for this and more...
* A purpose-driven mission tackling complex sustainability challenges while working alongside global industry pioneers at a fast-growing unicorn company
* Room for creativity through collaborative teamwork and an open communication culture
* Flexibility and team bonding with our hybrid work options
* Fuel for your growth journey, both personally and professionally
* Sustainable mobility options, promoting eco-friendly commuting solutions
* Fun team events and outings with our general teams
* Inspiring workspaces in Munich, Madrid and beyond
