Sébastien Schikora - Chief Technology Officer

Hi there!

I'm Sebastien Schikora, serving as the CTO at Flexa since the beginning. My diverse career journey has provided me with a range of experiences with a deep dive in the energy industry and the functioning of the grid specifically. In the last years, I was:

  • CTO at KONUX from September 2018 to April 2022, where I played a pivotal role in shaping the company's tech landscape and products.
  • Sr. Manager at Tesla from November 2015 to July 2018, leading the development of energy storage systems and mobile apps.
  • Vice President of Product Development at Networked Energy Services (NES) Corporation from October 2014 to November 2015, launching a new company and product line in the grid digitalization space.
  • At Echelon Corporation,  I held various roles over six years, including Director of Product Management and Development in the Grid Modernization Division.
  • Before my endeavors in the Energy Industry I was working for Hewlett Packard in the Enterprise Software group for a little over 10 years.
I'm all about pushing the boundaries of technology and driving progress in our industry. I spent the majority of my career in the Silicon Valley in California and apply a lot of the methods and drive to my workplace here in Munich. 

Our team is the basis of our success, and I'm dedicated to fostering a collaborative, innovative and goal driven work environment.

If you're ready to be a part of our international crew and share our vision for groundbreaking tech solutions, I encourage you to explore opportunities within our organization.

Thanks for considering joining us, and I look forward to the possibility of working together to achieve remarkable things.

Best regards,
