Pros

The mission is motivating. The vast majority of my coworkers are impressive and fun to work with. Helion moves quickly and is far ahead of most other fusion startups. The culture is positive. People work hard because they care, not because their boss is making them.

Cons

Goals and timelines can feel arbitrary and overly ambitious. The media hype machine clashes with the sterile scientific reporting I prefer. Moving fast can sometimes mean flexibility of hours and plans changing quickly. Formal processes are taking shape slower than the company is growing.

Pros

Really smart people, fun to work and collaborate with other teams which happens a lot because everyone is building rigorously. The benefits are top tier, and the company has seen explosive growth. Exec team is very approachable and in the day to day, a lot of face time with them.

Cons

Can be noisy with all the growth and production going on right next to admin employees, but it's better than not having a thriving company.

Pros

The mission of the company is motivating, and the culture is diverse and inclusive. It is for the most part a fun environment.

Cons

There are no perks to being a salaried supervisor at Helion. No bonus, no shift differential for night shift. Health benefits are mediocre at best. Being free to the employee doesn't equate to good insurance.
