There's always a solution, Marion - Sales manager

Marion joined Séché Environnement ten years ago as a sales administration assistant, and with no technical background whatsoever, she never thought she'd become a sales manager. And yet, thanks to her thirst for learning, she now plays a key role in the development of the hazardous waste incineration business. She shares with us her vision of a constantly evolving sector.

Can you tell us about your career path ?

I joined Séché Environnement in 2013 at the Trédi subsidiary, on the Saint-Vulbas site, as a sales administration assistant. I then progressed to a sales manager position, which enabled me to strengthen my technical expertise and my taste for customer relations. Today, as Sales Manager, I’m involved in the development of the hazardous waste incineration business. I’m responsible for both the operational deployment of the strategy, and for supporting my team.

How would you describe your job today?

I’m in direct contact with customers, sales teams and operations. My role is to adapt the Group’s vision to the realities of the market and the needs of our customers.

To offer them optimized, sustainable solutions, it’s essential to maintain contact in the field and be as close as possible to our partners. Objective to guarantee the proper handling of their waste, help reduce their environmental footprint, optimize the recycling of materials, and produce low-carbon energies, alternatives to fossil fuels.

Trade fairs such as the

Trade shows like Pollutec can be key moments to meet prospects and identify opportunities for collaboration with our most loyal customers by focusing on Group synergies.

You also manage a team?

I’ve been in this job for two years now, and I’ve come to understand the importance of surrounding myself with the right people. I believe that being a good manager means allowing everyone to fully express their skills where they are most useful. I’m committed to supporting my colleagues in developing their experience and defining their next professional challenges together!

What motivates you on a daily basis?

We’re in an industry that makes sense  being able to support our customers in better managing their waste is an essential mission for the environment.

Moreover, every day is different: changing customer needs, regulations and industrial challenges mean that nothing is ever set in stone. You have to keep adapting and learning new things, and that’s what I particularly like about this job!

Finally, even though it’s growing fast, the Group remains a family business that values atypical profiles like mine, and allows real career development. I started out with no technical background and never thought I’d one day become sales manager for the hazardous waste incineration business. But thanks to my constant desire to learn and the confidence I’ve been shown throughout my career, I was able to seize this opportunity, and I don’t regret it !

What advice would you give to a candidate?

Have a sense of service and never consider a problem unsolvable ! Customer orientation must be at the center of his or her concerns. It’s crucial to be out in the field, listening to customers’ concrete needs, to understand their expectations and meet them with appropriate technical proposals. Resilience is also an essential quality: there’s always a solution, you just have to want to find it! This is precisely the Group’s strength  there’s a multitude of expertise, and employees always know how to make themselves available, which makes constant innovation possible.
