Sébastien Schikora - Chief Technology Officer

Hi there!

I’m Sébastien Schikora, and I’ve been driving tech innovation as CTO at Entrix since June 2022 and Flexa since February 2024. My career has been a mix of exciting challenges and opportunities, with a strong focus on transforming the energy industry and reshaping how electricity grids work and the best is yet to come.
Here’s a quick snapshot of my journey so far:

  • CTO at KONUX (2018–2022): Shaped the company’s tech vision, built world-class products, and scaled technology to solve big problems.

  • Senior Manager at Tesla (2015–2018): Led the charge in developing cutting-edge energy storage systems and seamless mobile experiences.

  • VP of Product Development at NES Corporation (2014–2015): Helped launch a new company and product line, disrupting grid digitalization.

  • Echelon Corporation: Spent six years driving innovation in grid modernization and smart metering, from product management to development leadership.

  • Hewlett Packard: Before diving into energy, I spent over a decade refining enterprise software solutions.

Having spent most of my career in Silicon Valley, I bring a mindset that’s all about pushing boundaries, moving fast, and creating meaningful impact. Now based in Munich, I apply that same energy to building teams and driving innovation here in Europe.

At Entrix and Flexa, we believe great tech starts with great people. Collaboration, creativity, and an unrelenting focus on delivering results are at the heart of everything we do.

If you’re ready to work with a team that’s reshaping industries and tackling some of the toughest challenges out there, I’d love for you to check out our opportunities. Join us, and let’s build something extraordinary together.

Looking forward to seeing what we can create.

Best Regards,

Sebastien Schikora

About us
With our AI-powered fully automated optimization and trading platform for flexible energy assets from grid-scale batteries to virtual power plants, we ensure that energy is stored when it is abundant and released into the grid when it is needed. At the same time, by actively trading electricity, we counteract strong price fluctuations that green energies entail. Figuring out how storage provides the best value to the electricity grid and the highest returns to asset owners is how we accelerate the transition to a clean energy future.

Marco Pennacchiotti- Head of Data Science and Data Engineering


I joined Entrix in August 2024. My mission is to build a world-class team of Data Scientists that solves some of the most challenging data science problems we face today, ultimately contributing to save the planet, one Megawatt at a time.
Before joining Entrix, I worked at Meta, eBay, Yahoo! and BMW, always with a focus on Machine Learning and big data, and on solving real-world problems, be that improving search engines’ algorithms, building autonomous driving vehicles or fine tuning Large Language Models.


I love Entrix because it enables me to combine my passion for data and algorithms with my commitment to save the environment, by working on projects that are at the forefront of the energy transition, machine learning and data science. Also, at Entrix I rediscovered that entrepreneurial and getting-things-done spirit that I missed so much after coming back to Europe from my time in Silicon Valley.

As a manager, my goal is to empower individuals to work in autonomy, help them deliver value in production, work across functions as “one team”, and grow in their career path focusing on their strengths. I strive to build an informal environment where everybody can be productive, communicate openly and freely, and ultimately have fun while feeling a strong sense of achievement.
