At Sierra Piedmont Engineers & Geologists,
we believe experience matters. We are a boutique, environmental engineering firm, 30 years in service located just north of Atlanta. Our team includes professionals at every stage of their careers, and we deeply value the knowledge and perspective that come with your decades of experience.

This position is ideal for a seasoned professional, especially in the mid to later stage of career. You’ll lead projects hands-on, share your knowledge generously, and act as a trusted voice internally and with clients. The ideal candidate will bring not only technical expertise and leadership but calmness under pressure to lead high-impact projects, mentor staff, and help guide our continued success.

• Help shape strategy and operations as a senior member of a small leadership team — your opinion will be heard

• 20+ years of professional experience in environmental consulting or environmental engineering
• Professional Engineer (PE) or Professional Geologist license in Georgia preferred
• Strong knowledge of federal, state, and local environmental regulations
• Exceptional communication skills — verbal, written, and interpersonal
• A collaborative and mentoring approach to leadership
• Proven ability to manage technically complex projects and client relationships
• Comfortable operating in a boutique, high-performance consulting environment

• A leadership role in a specialized firm that works primarily with blue-chip clients
• A company culture that values expertise, integrity, and long-term relationships
• A seat at the table in shaping the future of a respected boutique firm
• Respect for experience — we value professionals who’ve seen a lot and still care deeply about doing the work right

This role is ideal for a seasoned environmental professional who enjoys being deeply involved in the work, thrives in a small, high-trust team, and is ready to bring wisdom and leadership to a firm that values both.
