Company Description
Are you passionate about energy, sustainability and technology as well as driven by sales?
At Flexcity, we help the European power system become smarter, more flexible, and more sustainable by connecting industrial assets (batteries, e-boilers, heat pumps, data centers…) to energy markets.
A subsidiary of Veolia Group, we combine the agility of a scale-up with the stability of a global leader in ecological transformation.
Today, we are accelerating our growth in Belgium and are looking for a Technical Account Manager to support this expansion in a key market: industrial decarbonization.
Job Description
Historically, heat-intensive industries have relied heavily on gas to produce steam and industrial heat. With European climate targets, these uses must evolve, and Power-to-Heat technologies (e-boilers, heat pumps, thermal storage) play a central role in this transition.
At Flexcity, we believe that electrical flexibility is a key lever for this transition. In Belgium, we aim to structure and accelerate this market.
As a Technical Account Manager, you will be at the heart of this effort. You will develop an industrial client portfolio, support their decarbonization projects, and become a trusted partner on their energy challenges.
Reporting to the Head of Growth, your role is organized around three main areas:
Commercial Development (60%)
* Identify, prospect, and sign new industrial clients in Belgium.
* Manage the entire sales cycle, from first contact to asset onboarding in our portfolio.
* Represent Flexcity at industry events, conferences, and workshops.
Key Account Management (25%)
* Build long-term relationships with strategic clients, closely collaborating with portfolio and operations teams.
* Identify cross-sell and up-sell opportunities.
* Maintain client proximity through regular touchpoints and on-site visits.
Internal Coordination & Pipeline Management (15%)
* Keep a clear and reliable pipeline in the CRM.
* Be the voice of the client internally, sharing feedback, needs, and opportunities with product, portfolio, and operations teams.
* Contribute to continuous improvement of our market approach.
