Customer Success Lead

Make every customer feel like the only customer - and build the proof that we deliver.

Enersee has raised €4M and is getting ready for the next stage:
becoming the market leader and getting Series A ready. What took four years to build, we plan to 5x in the next 12 months.

We’re not looking for a CS leader who builds frameworks from a distance.
We’re looking for someone who gets the job done.
Someone who can onboard a customer in 5 days, not 10 weeks.
Someone who can say no to a customer and make them feel special at the same time.
Someone who knows that Customer Success is a revenue function - not a support function.

About Enersee

We don’t like waste.
Not waste of time.
Not waste of energy.
Not waste of potential.

We built a proprietary AI-powered virtual manager for energy, sustainability, and facility leaders. Not a ChatGPT wrapper. A sophisticated machine learning engine that analyzes building data, detects inefficiencies, and delivers real-time, actionable insights. We already work with enterprise names like Belfius, VDAB, and Ahold Delhaize - and we’re moving toward some of Europe’s largest multinational portfolios.

What you’ll do

• Own onboarding end-to-end: Take new customers from signed contract to first value in ≤14 days. Run structured kickoffs, configure the platform, and make sure they’re set up for success from day one.

• Drive adoption and retention: Monitor account health, run proactive outreach when scores drop, and deliver monthly usage reviews. Your accounts renew because they see value - not because they forgot to cancel.

• Be the voice of the customer internally: Feed product insights back weekly. You’re the bridge between what customers need and what we build next.

• Deliver QBRs that matter: Not slide decks. Real conversations about ROI, usage, and next steps. Make customers feel heard and accountable.

• Spot and surface expansion: Flag upsell and cross-sell opportunities to Sales. You own the relationship; you see the signals first.

• Handle the hard conversations: Scope creep, unrealistic expectations, feature requests we won’t build. Say no with clarity, empathy, and conviction.

• Build the proof: Create case studies, secure references, and turn happy customers into advocates.

Our ideal hire

• Most of all: You are a FIXER. You make it happen. Every customer will be a success. Whatever it takes! FAW (Find A Way) is your favorite abbreviation and results are what drives you (technology as a means, not an end)

• Ex Project manager or Project engineer: Ideally, you know how to make a customer succeed. You understand the management, controlling expectations and the narrative and have enough technical knowledge to communicate what you need with the product team (and sometimes fix things yourself)

• Hands-on CS experience in SaaS: You’ve managed a book of business. You’ve owned retention and expansion metrics personally - not through a team.

• Metric-driven: You know your NRR, your GRR, your CSAT. You don’t just “manage relationships” — you manage outcomes.

• Exceptional communicator: You can run a QBR with a CFO and troubleshoot a platform issue with an operations manager - same afternoon.

• Graceful under pressure: You’ve handled difficult customers, scope creep, and churn risk. You stayed calm, found a path forward, and kept the customer.

• Structured and self-driven: You don’t need someone to tell you what to do. You build your own systems, follow your own playbooks, and hold yourself accountable.

• Languages: Fluent in English plus at least one major EU language (Dutch, German, French or Spanish).

• Office first from Antwerp (with Hybrid flexibility): Our default is office first, with a minimum of 3 days a week office (most people are here 4-5 days a week).
  You understand the urgency of the growth phase, we sync and execute at breakneck speed.

Bonus points if you have energy sector experience, especially around building efficiency, decarbonization, or smart building solutions. Know ISO 50001 or IPMVP®? Even better.

What you get

This is a high-standard, high-upside environment.

• Competitive base salary + performance-based variable

• Stock options after 1 year vesting

• Direct exposure to leadership and customers from day one

• A real impact on our Series A story

• Systems and processes in place - we need someone to execute, not to figure out the playbook from scratch. Though you will have to adapt and optimize the process as we move forward – We are still a scale-up. Figuring things out!

We reward performance. Not tenure.

A Note on Standards

If you’re serious about this role:

• Research our product and our customers

• Think about what you’d do in your first 30 days

• Come with a point of view on how you’d make our customers love us

Customer Success requires initiative.

So does joining Enersee.
