Rachael
Sustaining Engineering Manager
Working at AES has been both rewarding and exciting. Working alongside highly skilled and experienced engineering and manufacturing floor teammates has helped me grow as an engineer and as a manager. Everyone brings a unique perspective and approach to the table which helps to achieve our goals in making the most powerful chambers on the market. The perk of being able to bring my dog to work and socialize with other dogs has been awesome as well!
John
Vice President
I started in the 1980s with an internship, and now I have been with AES for more than three decades. I have seen the transition from analog to digital test chambers, the development of remote testing, and what has driven changes in environmental testing.
