O&M Technician — Battery Energy Storage; BESS​/Power Systems

O&M Technician — Battery Energy Storage (BESS) / Power Systems

Clean Energy Services (CES) was founded on four core values:
Safety, Quality, Trust, and Efficiency.

We are looking for motivated individuals who want to grow with our company and contribute to our culture of excellence. Because CES supports projects across multiple regions, this role is designed for people who are comfortable working at locations outside their home area and who enjoy traveling to new sites as part of their regular schedule.

Safety is everyone’s responsibility. All employees are expected to actively participate in CES’s safety programs, speak up about safe/unsafe conditions, and always report incidents—no matter how minor. Every employee has both the right and the obligation to stop any work they believe is unsafe or unclear.

As a member of our field team, you are often the first point of contact with our clients. We expect professionalism, positivity, and strong representation of CES at all times. If you see opportunities to improve our work processes, we want you to raise them.

Project work requires attention to detail, thoughtful planning, and full participation from everyone on site. No one should remain idle when others are working. We expect employees to properly care for and maintain their equipment and to use downtime for maintenance or other improvement work.

• Fair treatment and growth opportunities. We invest in people who want long‑term careers with CES and provide clear paths for advancement.
• Annual performance bonuses based on results and tenure.
• Spot bonuses recognizing exceptional safety practices and job performance throughout the year.
