Job Summary

Job description
Make Europes biggest buildings waste less energy and be measured on it

Enersee raised 4M and is going for Series A. What took four years to build we intend to 5x in the next twelve months. We work with Belfius VDAB Ahold Delhaize Veolia and Stad Kortrijk and were moving into some of Europes largest multinational portfolios.

We built a proprietary AI-powered virtual manager for energy sustainability and facility leaders. Not a ChatGPT wrapper a machine learning engine that reads building data finds the inefficiencies nobody spotted and turns them into something a facility manager can act on Monday morning.

We need someone to make sure customers feel that. Every time.

If your title has never said Customer Success keep reading

The person were looking for may well not have worked in Customer Success before.

If your path took you somewhere from civil engineering and computer science then consulting programming then product management then customer relationships this will work here. If youre a project engineer technical consultant implementation lead or energy consultant who has been drifting steadily toward customers and away from pure engineering youre the profile.

What this role is not

It is not back-office data support. You will own a book of enterprise accounts end to end onboarding adoption renewal expansion and youll carry those numbers personally. Youll sit with a customers energy manager and their CFO in the same afternoon. Customer Success here is a revenue function and the commercial upside of your accounts is yours not someone elses.

Job requirements

The three things were hiring for

Were looking for one of these already strong and clear talent in the other two. Nobody arrives excellent at all three and were not pretending otherwise.

1. Technical affinity and energy literacy

You dont need a technical degree but this is a genuinely technical job and wed rather be blunt about it than have you find out in month one.

On the energy side: you should be comfortable with kW versus MW versus kWh know the difference between a main meter and a sub-meter and have some feel for why electrical load in a nursing home looks nothing like a logistics warehouse. ESG reporting shouldnt be a new phrase. If you dont have all of this yet you need to be the kind of person who finds it interesting rather than tedious because our customers live in it.

2. Project management

This is the backbone. Youll run several enterprise customers at once and break each account into real milestones with real dates.

Youll also work backwards from decision dates. Expansion and renewal conversations are effectively decided about two months before they happen which means the value has to be delivered documented and visible before the customer starts building next years budget not assembled in a hurry afterwards.

3. Product championing

Youre a strong communicator who can make people genuinely want the thing. Youll spot where an account should grow build the business case that takes a customer from pilot to full portfolio rollout and know exactly when to bring Sales in rather than freelancing a deal yourself. And youll carry customer reality back into product every single week.

What youll actually do

  • Take new customers from signed contract to first value fast structured kickoff platform configured data flowing stakeholders aligned

  • Own account health: proactive outreach when engagement drops regular usage reviews and renewals that happen because customers see value rather than because they forgot to cancel

  • Run Quarterly Business Reviews that are real conversations rather than slide decks ROI usage next steps honest accountability in both directions

  • Build the business cases that move customers from pilot to full rollout

  • Surface expansion signals to Sales; you own the relationship so you see them first

  • Handle the hard conversations scope creep unrealistic timelines features weve decided not to build. Say no with clarity and empathy and keep the customer

  • Build the proof: case studies references customers wholl happily take a call from a prospect

  • Track it properly with HubSpot dashboards for retention and expansion. You should know your NRR GRR and CSAT without opening a file

  • Shape the CS practice itself as we scale

What youll need

  • A track record of owning customer outcomes personally at a SaaS scale-up or with enterprise clients or a project management / project engineering record you can walk us through plus real appetite for a commercial customer-facing role

  • Grace under pressure. Youve handled difficult customers scope creep and churn risk stayed calm and found the path forward

  • Structure and self-direction. You build your own systems and hold yourself to them without being asked

  • Fluent English plus at least one of Dutch German French or Spanish. Dutch is a strong advantage for our Belgian portfolio

  • You are office-first minimum three days a week in the office but there is also flexibility to work from home.

  • Genuine comfort with pace and ambiguity.

Nice to have: energy sector background particularly building efficiency decarbonisation or smart buildings. ISO 50001 or IPMVP. Experience with HubSpot Mixpanel Intercom or BI tools.

An honest note on what youre walking into

Some things are in place: HubSpot a working onboarding motion existing customer materials and a product team that ships fast. Other things arent. Our CS practice is young and youll be rebuilding parts of the playbook while youre running it.

You should also know that youd be inheriting real work rather than a clean slate. Weve grown quickly while simultaneously shipping a major new version of the platform which means a handful of onboardings have been waiting on capacity and some accounts havent had the depth of attention they deserve. Clearing that is a large part of why this role exists. If that sounds like a mess it isnt the job for you. If it sounds like an obvious set of wins sitting there unclaimed we should talk.

Compensation and benefits

  • Competitive base salary (incl. 13th month & double vacation pay) performance-based variable

  • Stock options: available after 1 year for our top performers

  • Company car or mobility budget extra salary

  • EV charging card

  • Meal vouchers (8/day) eco vouchers (250/year)

  • Hospital insurance family discounts

  • Laptop smartphone 30/month connectivity

  • Office in Antwerp GEO work flexibility for multiple weeks per year

All done!
