Position summary

osapiens, a fast-growing compliance and supplier-intelligence SaaS company, is hiring a Senior Onboarding Consultant – Carbon & GHG Management to take its largest and most complex Carbon customers live. The role runs complex carbon onboardings end to end, making the early decisions that determine success: system boundaries, which Scope 3 categories are in, and where primary data is worth collecting versus where an emission factor will do.

Why this role matters

A carbon onboarding succeeds or fails on decisions taken in the first three weeks. The role leads customers through those decisions, owns the sequence and scope, and leaves the delivery team better equipped for the next project.

Key responsibilities

• Run complex onboardings end to end across scoping, configuration, data integration, key-user training, go-live and a documented handover to Customer Success for the largest and most complex accounts.
• Own effort and budget by estimating realistically, staying inside booked hours and triggering a follow-up sale with CS and Sales when overconsumption is coming rather than quietly continuing to deliver.
• Make the next project cheaper by building onboarding packages, checklists and self-service content (e.g. eLearning) for standard use cases and using the Solution Expert’s enablement material consistently.
• Coach the team by reviewing junior consultants’ project plans and configurations, stepping in on difficult customer situations and feeding the skill matrix.
• Work with the Solution Expert by escalating genuine edge cases and playing back recurring questions and product gaps.
• Build decision-maker relationships during onboarding and hand them to CS with a documented stakeholder map.

Team and stakeholders

The role sits in the Delivery – Solution Excellence department, working with Customer Success, Sales, the Solution Expert and more junior consultants. The split is roughly 70% own onboardings, 15% coaching/review, 10% standardisation and 5% collaboration with the Solution Expert.

Key details

• Permanent, hybrid role (3 days per week in office), based in Munich, Mannheim or Madrid.
• Travel below 10%; onboardings run largely remote.

Requirements

• Several years of project experience in SaaS implementation or consulting in carbon accounting or sustainability reporting, with full responsibility for the customer rather than a single 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.
• An instinct to standardise recurring work into reusable packages.
• Budget and scope discipline, stating engagement limits clearly rather than absorbing scope creep.
• Fluent English; German or Spanish is a plus.
