Salary: £60,000–£65,000 base + Bonus
All Candidates must have:

About the Company
We're partnering with a fast-growing sustainability SaaS company helping some of the world's largest organisations tackle complex environmental challenges across global supply chains.
Their technology enables enterprise organisations to better understand sustainability performance across their supplier ecosystems, improve engagement and turn complex environmental data into measurable action.
Working with major global organisations across manufacturing, automotive, healthcare and consumer goods, the business is continuing to scale its enterprise customer base and is now looking for an experienced Senior Customer Success Manager to join the team in London.
The Role
This is a strategic, customer-facing role focused on managing a portfolio of complex enterprise customers and helping them successfully deliver sustainability programmes across their organisations and supply chains.
You'll own relationships from onboarding through to renewal and expansion, working with senior stakeholders to understand their sustainability objectives, build success plans and ensure they're generating measurable value from the platform.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
This goes beyond traditional SaaS account management. You'll need to understand the sustainability challenges your customers are trying to solve, confidently advise senior stakeholders and translate their objectives into successful programmes.
You'll also bring a strong commercial mindset, identifying risks, protecting retention and uncovering opportunities to grow strategic accounts.

- Own a portfolio of strategic enterprise customers
- Build trusted relationships with senior sustainability, procurement, supply chain and operational stakeholders
- Develop customer success plans aligned with sustainability and business objectives
- Lead executive business reviews and strategic customer meetings
- Drive platform adoption, engagement and measurable customer outcomes
- Support customers with supplier engagement and sustainability programmes
- Monitor customer health, identify risks and proactively protect retention
- Own and support renewal conversations across your portfolio
- Identify expansion opportunities alongside the Commercial team
- Translate customer feedback and market requirements back into Product
- Maintain accurate account, engagement and opportunity data within HubSpot
Essential Experience
- Proven experience working within sustainability, ESG, climate tech, carbon management or a closely related sustainability field
- Strong experience managing large, complex enterprise customers
- Track record within Customer Success, Strategic Account Management or another strategic customer-facing role
- Experience engaging senior and executive-level stakeholders within enterprise organisations
- Strong understanding of how large organisations approach sustainability programmes and transformation
- Commercial experience across retention, renewals and account growth
- Ability to manage complex, multi-stakeholder customer relationships
- Strong communication, presentation and relationship-building skills
