Job Overview

We’re looking for a highly capable and experienced Customer Success Manager to lead complex customer implementations and onboarding. This role is ideal for someone who enjoys navigating sophisticated customer environments, can build trust with senior stakeholders, and thrives in fast-moving, ambiguous contexts.

This is not a "plug-and-play" onboarding role — our customers are often large, multi-stakeholder organizations with complex technical and operational setups. Implementations are strategic, cross-functional, and high-touch, often requiring several months from kickoff to value realization. You'll need to bring credibility, confidence, and structure — while building the very processes and materials that don’t yet exist.

You’ll also support the commercial team in the pre-sales phase, helping shape implementation plans and technical feasibility assessments before a deal is closed.

What You'll Do

Complex Onboarding & Implementation

• Own the onboarding journey for new customers, coordinating internal and external stakeholders to deliver a seamless, strategic implementation.
• Understand and document customers' technical environments, data infrastructure, and operational goals — and adapt implementation plans accordingly.
• Facilitate the integration of Fever’s platform into customer systems and workflows, working closely with product and engineering.
• Set the tone from day one with professionalism and clarity — representing Fever with a level of gravitas that earns trust.
  
  

Customer Enablement & Strategic Guidance

• Deliver tailored training and enablement to ensure stakeholder buy-in and early adoption.
• Proactively manage onboarding risks, dependencies, and timelines — acting as the customer's trusted advisor during the most critical phase of the relationship.
• Ensure a thoughtful handover to the Customer Success Lead once customers are live and stable.
  
  

Pre-Sales Support

• Work with the sales and partnerships teams to provide implementation scoping and pre-sales support — especially for complex or enterprise prospects.
• Contribute to RFPs, solution design conversations, and feasibility reviews to ensure what’s being sold can be successfully delivered.
  
  

Build While Doing

• Help lay the foundation of our onboarding and success processes — creating templates, toolkits, and workflows that scale.
• Bring a continuous improvement mindset — sharing learnings from each implementation to improve the next one.
• Collaborate with product and engineering to ensure customer insights feed into product development.
  
  

Must Have

• 3–5+ years of experience in a customer success, onboarding, implementation, or solutions role — ideally in a complex B2B SaaS, enterprise-level, platform-based environment. Bonus points for energy/cleantech.
• Technically adapt — you have experience and understand systems integrations, APIs, and data flows, even if you’re not hands-on technical.
• Manage complexity - Proven ability to manage complex, multi-month implementations across and manage technical and business stakeholders.
• Gravitas and professionalism — you know how to inspire confidence and build relationships with demanding customers.
• Solution development - Experience contributing to or leading pre-sales efforts, including solution scoping and implementation planning.
• Bias for action - Comfortable navigating ambiguity and building structure and processes where none exist.
• Communication skills. Excellent communication, project management, and problem-solving skills.
• Fluent in English; Swedish or other Nordic languages are a bonus. Unshakeable sense of humor, empathy, and sharp judgment—crucial attributes for fostering strong relationships, communicating clearly, and making pivotal decisions.
  
  

Nice to Have

• Background in energy, enterprise software, or other complex B2B industries where solutions require deep integration.
• Familiarity with SQL, APIs, automation tools, or customer success platforms (e.g., Gainsight, ChurnZero, Salesforce).
• Experience in a startup or early-stage company, scaling CS from the ground up.
  
  

What We Offer

• An opportunity to witness the success of a groundbreaking product from its early stages.
• An experienced team who have some great (and terrible) humour!
• Equity - QESO stock options
• Competitive market salary
• Pension
• Enhanced Maternity and Paternity leave
• Health Insurance
• 30 day annual leave
• Great office environment (and whoever said there was no free lunch?)
