A Short Note from Your Future Lead


Dr. Christian Buckl
Head of Software - Entrix & Flexa
Hi there!
I'm Christian Buckl, Head of Software at Entrix & Flexa. My professional journey has been deeply rooted in the intersection of technology and industry spanning areas such as autonomous driving and cloud-based systems that serve millions of users. Over the years, I've had the privilege of contributing to various innovative projects and leading teams dedicated to pushing the boundaries of what's possible in our field.

• At Lyft (2018–2024), I initially built the in-car middleware system for autonomous driving. Later, my team and I developed the in-house mapping stack—including the routing engine and estimated-time-of-arrival (ETA) system—powering millions of rides.
• At Apple (2016–2018), I led a team in the Special Projects Group focused on autonomous systems.
• At Siemens (2015–2016), I spearheaded software development for a startup within Siemens, creating a hardware/software platform for autonomous electric vehicles.
• Before that, I was a founding member of fortiss, a non-profit research organization in Munich.

At Entrix & Flexa, we believe that our success is built on the strength of our team. We foster a collaborative, forward-thinking environment where everyone can thrive and make a meaningful impact. Having spent over eight years working for Silicon Valley companies, I bring that experience to help shape our innovative culture.
If you're passionate about pioneering technological solutions and eager to be part of a dynamic and international team, I encourage you to explore the opportunities we offer. Together, we can drive innovation and achieve remarkable milestones.
Thank you for considering a future with us. I look forward to the possibility of working together to shape the future of technology,
