About Cornerstone Energy Services

Cornerstone Energy Services, Inc. specializes in engineering, survey, and land solutions for the energy infrastructure sector. From initial concept through project completion, we provide comprehensive services including civil, process, mechanical, and I&E engineering; project management; survey and mapping; and right-of-way acquisition.

We collaborate closely with developers and operators of oil and gas pipelines and electric transmission systems, supporting both extensive linear projects and site-specific developments. Our work is guided by three core values:

• Safety – protecting the public, our clients, and our team
• Advocacy – prioritizing the best interests of our clients
• Integrity – upholding professionalism and accountability in every aspect of our operations

The Principal Electrical Engineer leads the electrical design of projects at natural gas facilities, from conceptual studies through construction and commissioning. The role owns technical quality for power distribution, hazardous area classification, grounding, lighting, and instrumentation and control interfaces. The Engineer serves as a primary technical contact for clients, mentors’ junior staff, and ensures every deliverable meets applicable codes, client standards, and Cornerstone's safety expectations
