Senior Climate Solutions Manager; m​/f​/d

About Cozero

Cozero is a climate tech SaaS company on a mission to make carbon management accessible and actionable for businesses worldwide. Our platform helps enterprises measure, understand, and reduce their carbon footprint
, from building robust carbon accounting frameworks and applying the right emission factors, to designing meaningful decarbonization strategies that drive real-world impact. We're a young, ambitious team that moves fast, thinks creatively, and genuinely cares about the work we do.

We are looking for a Senior Climate Solutions Manager to join our Climate Solutions team and help enterprise customers move from carbon data to meaningful climate action. This is a highly customer-facing combining sustainability consulting, carbon accounting, decarbonization and SaaS customer delivery. Your time will be split approximately 70% across customer projects and accounts and 30% across climate methodology and product-related work
. You will lead consultative projects around decarbonization strategies, transition planning, target setting and sustainability reporting

This is not a purely strategic advisory position.

• Answer customer questions across corporate climate action - accounting, reporting, decarbonisation, supplier engagement - and handle the bulk of them yourself, including the support that happens outside the platform: how customers can improve their data quality, reviewing mappings, and making sense of their own log data.
• Support in more strategic customer conversations.
• Translate standards and regulation - GHG Protocol, CSRD/ESRS, SBTi, transition planning - into concrete guidance for a specific company in a specific industry.
• Work directly with customer emissions data to identify data-quality gaps, understand emission hotspots and determine where the greatest reduction potential sits.
• Bring customer insights back to our Product, Data and Climate teams, helping shape product development and improve our internal processes.

• Bring 3+ years of hands‑on experience in corporate sustainability, ideally within sustainability consultancy, climate tech company in an advisory, solutions or customer‑facing role.
• Have strong practical knowledge of corporate carbon accounting and the GHG Protocol, including Corporate Carbon Footprints (CCF), Product Carbon Footprints (PCF) and Scope 1, 2 and 3 emissions.
• Have applied frameworks such as CSRD/ESRS, SBTi, supplier engagement and transition planning to real companies and real data.
