How We Work: 

Our mission is to help create, develop, and support an environment where great people come to do their best work. We believe there is a balance to strike between “work hard, play hard,” and we strive to improve in both areas every day. 

We put our customers, employees, and communities at the center of everything we do. It all comes back to our core values:    

Be Good - Nitronauts are good humans with big hearts that are respectful and supportive of each other. We celebrate individuality and diversity and strive to foster an environment where people can be themselves and do their best work.     

Performance First - We like to challenge ourselves. We’re passionate about exceeding expectations and stepping outside our comfort zones to get to the next level. It’s our ambition that pushes us to work hard and deliver strong results.   

No B.S. - This one is self-explanatory, but we’re all about transparency, honesty, and authenticity here. We don’t beat around the bush; we tell it like it is.

What we're looking for:

  • Experience with securing cloud platforms and approaches engineering with a security-first mindset
