An Insider's view of Boom Supersonic

What’s the vibe like in the office?

The high quality team at Boom is what really sets the vibe for the office. I’ve never worked with so many smart, talented, and passionate people. The best part though, is the incredibly collaborative approach that the entire team takes to solving problems and building a product. There is no “stay out of my sandbox” mentality.


Lead Engineer, Flight Controls

What kinds of technical challenges do you and your team face?

New technical challenges arise daily with solutions fueled by motivated engineers. Talented and energetic employees are the norm, many of them early in their careers, all of whom are eager to learn, willing to think differently, get their hands dirty, and work together to send supersonic aircraft screaming through the sky.


Principal Stress Analyst

How has your career grown since starting at the company?

Prior to starting at Boom, I worked at a global OEM. What I love most about this company is its focus on cross-collaboration, and how all the departments work together as a true, interdisciplinary team. Learning new things each day from innovative, inspiring coworkers has helped transform me into a better, more diverse engineer.


Materials & Process Engineer

What’s the vibe like in the office?

The vibe around the facility is a night and day experience compared to the aviation site I used to work at. Everyone from the CEO on down is hyper approachable seemingly every day. Here at Boom, we believe in hard work. We also believe in the concept of having a life outside of the good work we do here.
