About Enersee
Enersee is experiencing rapid growth. We raised 1.2 million in capital in June 2023 and are currently in the process of scaling up. Our mission is to make more hospitals, offices, and industries energy-efficient. To achieve this dream, we need a Customer Success Manager to ensure our clients are satisfied and can maximize the benefits of our product.
Maarten & Joachim, the founders, have a clear understanding of our product's capabilities and its potential beneficiaries. While they know how to market our message, they need someone to guarantee the optimal user experience for our clients and build lasting, sustainable relationships. This is where you come in, right?
What’s the job?
We are looking for a Customer Success Engineer with a passion for the energy sector. As a Customer Success Manager, your role involves ensuring the perfect user experience for our clients and establishing long-term relationships. Your responsibilities include:
- Implementing and enhancing onboarding processes.
- Maintaining relationships with clients, acting as their primary point of contact, and proactively addressing their needs.
- Identifying and understanding customer needs to ensure optimal product value.
It's about all-around customer success to ensure a seamless experience. Collaboration with various teams is crucial. You will closely work with the sales team to identify sales opportunities and successfully close deals. Smooth collaboration with the development team is also a must, integrating customer feedback into product improvements promptly.
What’s your profile?
Difficult to describe accurately, as we're open to different people. We've listed a few things that we think are important to fit into the Enersee culture and qualities that complement our current team:
- Master’s degree in engineering or another analytical field.
- Fluent in English and Dutch or French.
- You are the trusted peer for our potential and current clients.
- Experience as a Customer Success Engineer with experience in the tech environment or someone with experience in energy management. In an ideal world, you can do both😉.
- Interest in energy management.
- You are the trusted advisor for our clients, so both technical and sales skills are crucial, with a focus on results.
- Excellent communication skills complemented by strong technical abilities.
- Accurate, proactive, and detail-oriented.
- Strong collaboration skills and the ability to work in a fast-changing environment.
What will you get in return
The material stuff:
- A market-conform base salary.
- Fringe benefits such as: some text
- Meal vouchers
- Eco vouchers
- An electric company car OR a mobility budget
- Hospitalization insurance for you (free) and your family members (discount)
- 13th-month & double vacation pay
- A laptop and a mobile phone
- Mobile phone service and assistance with your internet costs.
We all have sustainable Enersee merch, little stuff that feels comfy or is fun to use, and also sustainable, the little extras…
The non-material stuff:
- On Monday and Wednesday, we work from Brussels. The other days you can work remotely or in the office, however, you prefer.
- We love to celebrate milestones. The day we raised the capital, we all went to an amazing restaurant with the team and +1s. New milestones, new celebrations.
- Once a week, we have a “Friday Win” session to celebrate our weekly achievements. Lunch and drinks are on us while putting the accomplishments of our team members in the spotlight. (and for the people that want to: we head into town afterward).
application process
What’s our application process like?
We believe a transparent and customized application process is super important, especially for our small startup. We want to get you to know the founders and the team deeper, so we can ensure we're all on the same page and share the same values. We must find candidates that are a great fit for our company culture. Does that sound good to you?
Step #1 - First screening
We screen your application and get back to you in three days or less. Either we don’t see the fit and we’ll let you know why not, or you move on to the next step.
Step #2 - Phone call
Either Joachim or Maarten will schedule a short call with you to get to know you already a bit. Who you are, what made you apply. But at the same time, explain what Enersee is about, what the job entails and maybe tackle any first questions you might have about working for us.
Step #3 - Video call/meeting in person
You had a call with one of us, now it’s time for a joint interview so both us know who our new colleague might be, and you get to see who is behind Enersee.
We’re a small team so we feel it’s important there’s a good vibe on both ends.
Got any questions? Feel free to ask away, we’re an open book.
Step #4 - Case/test study
Because we’re looking for someone to level up our sales strategies and impact, the fourth step will be a small case to show us how you’d approach one of our business problems. This gives us some insight into how your mind works and what’s possible in terms of sales that we haven’t even thought of. You’ll get a briefing at the end of step 3 and have a week to come up with the output and present it to us in 15’’...
Step #5 - Time for an offer
You’ve made it this far, we’ve gotten a good taste of who you are as a person and what your current skills are. Hopefully you feel you already know us a bit. If we both like each other, then it’s time to make it official by giving you a formal contract offer.
Step #6 - Offer signed, let’s plan your onboarding
We got the agreements signed? Great, then we’ll plan your onboarding. You can send us your shoe size so we can get the Enersee merch* ready on your first day. And we’ll celebrate the start of a fruitful partnership with our whole team on your first day. We’re looking forward to it!
*If you promise to wear it :D. Our merch is sustainably produced and meant to last.
