Chief of Staff

Job Description:

📍 Antwerp | Full-time | Senior

​

Enersee is scaling fast, and we need someone who keeps everything moving with it.  

Our proprietary AI-powered Virtual Energy Manager is already trusted by enterprise like Belfius, VDAB, and Ahold Delhaize. With €4M raised and Series A on the horizon, the next 12 months are all about 5x growth: new markets, bigger customers, a bigger team.

​

We're looking for a Chief of Staff who makes sure the CEO's time goes to the right things, that decisions actually get implemented, and that nothing falls through the cracks during one of the most critical growth phases we'll ever have - not someone who just writes strategy decks.

​

About Enersee

​

We don't like waste. Waste of time, energy, water, and efficiency. That’s why we built an AI-powered tool for energy, sustainability, and facility professionals. It uncovers hidden issues in building data, delivers real-time actionable insights, and helps organizations hit cost and emission targets. In short, we help companies save money while making the planet less wasteful.  

​

What you will do

​

• Be the CEO's right hand. Own the CEO's agenda, priorities, and bandwidth. Filter, prepare, and follow up so decisions happen fast and stick.  
• Drive cross-functional execution. Track what's been decided, who owns it, and whether it's actually happening. Identify when things are slipping before they become problems.  
• Prepare for next funding round. Own the data room, investor materials, and reporting cadence. You'll know our KPIs as well as anyone together with the CEO.  
• Run strategic projects end-to-end. Partnerships, market research, hiring processes, operational setups. When something doesn't fit neatly into anyone's role, it's yours.  
• Be the connective tissue. Make sure Sales, Product, CS, and Engineering are aligned on priorities and don't waste time on mismatches.  
• Represent Enersee externally with investors, partners, and enterprise prospects when the CEO can't be everywhere at once.

​

What we're looking for

​

• You've been at the centre of a fast-moving organisation in consulting, a high-growth startup, a VC, or a scale-up. You understand what "organised chaos" feels like and you thrive in it.  
• You get things done. Not by delegating or waiting for perfect information. You move, you adapt, you follow up.  
• You're sharp with data. You can build a financial model, pull together a board update, and spot when a number doesn't make sense.  
• You own processes and automation from sales to finance: In essence, you are a part time CFO as well, making sure no revenue gets missed, no KPI gets dropped. Obviously with the support of internal and external resources for bookkeeping and the like.  
• You communicate with precision. You write well, present well, and can hold a room with a CFO or a product team lead. You understand that getting a team to execute takes ****great storytelling that meets action bias.  
• You're comfortable with ambiguity. This role will evolve. What you work on in month 3 will look different from month 12. That energises you, not stresses you.  
• You speak the language. Fluent in English; Dutch and/or French a strong plus given our Belgian enterprise customer base.  
• You're office-first. Antwerp is home base, minimum 3 days/week. Most of the team is there 4–5 days.  
• You're wired for output, not hours. You do what's needed to get the work done, and you get flexibility in return.

​

What we offer you in return  

​

• Competitive base salary based on experience  
• Performance bonus (up to €25K/year)  
• Stock options: you grow, we grow  
• 13th month + double vacation pay  
• Company car (€35–50K) or mobility budget + extra salary  
• Meal vouchers (€8/day) + eco vouchers (€250/year)  
• EV charging card (private use included)  
• Hospital insurance + family discounts  
• Laptop + smartphone + €30/month connectivity  
• Offices in Antwerp and Brussels + hybrid flexibility
