EMPLOYEE TESTIMONIALS

Matt

Large and Custom Chambers Production Manager

I love coming to work every day where everybody takes their work seriously but not themselves too seriously. AES is a great place to work because it's a close-knit engineering company with a focus on collaborations and innovation. I am challenged every day with every task at hand.

Peter

Western Region Service Manager

During my seven years working with AES, I have participated in the growth and development of our manufacturing and service teams. Collaboratively, we are an unstoppable force in the chamber industry. It has been a fulfilling experience, and I look forward to the continued success of the company.

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. As Vice President, I have a hand in almost everything. Every day is always challenging and fun!
