Lead Mechanical Engineer

CONCORD ENGINEERING GROUP, INC. a full-service MEP engineering, commissioning, construction management and energy consulting firm with offices in Voorhees, Linwood and NYC, is searching for a Lead Mechanical Engineer - On-Site Power Generation as part of our Power & Infrastructure Department. In this position, you will have the opportunity to lead complex on-site power generation projects in a collaborative, technically driven work environment. In addition, this position will provide you with long term professional growth and leadership development.

POSITION SUMMARY

We are seeking a Lead Mechanical Engineer with a minimum of 12 years of experience specializing in on-site power generation, central utility plants, and large-scale thermal generation and distribution systems serving mission-critical campuses. This role provides technical leadership for the planning, design, and execution of combined heat and power (CHP)/cogeneration plants, chilled/hot water and steam systems supporting hospitals, universities, industrial campuses, utilities, and data centers. The successful candidate will bring deep technical expertise, strong leadership capability, and experience delivering reliable, efficient, and resilient utility infrastructure.

RESPONSIBILITIES

• Lead the design and engineering of central utility plant chilled/hot water and steam systems, including chillers, boilers, cooling towers, pumping systems, heat rejection equipment, and thermal energy storage.
• Lead the design and engineering of on-site power generation facilities with industrial and aeroderivative combustion turbines, natural gas reciprocating engines, heat recovery systems, and the typical mechanical balance-of-plant equipment, including HRSGs and duct burners, steam turbines, fuel gas systems and compressors, emissions control (SCR and oxidation catalysts), cooling systems, and plant piping.
• Engineer large-scale chilled water, hot water, and steam distribution networks for campus environments, including hydraulic modeling, redundancy strategies, and future expansion planning.
• Develop and review basis of design documents, engineering calculations, equipment specifications, construction drawings, and technical reports.
• Perform mechanical engineering analyses, heat and mass balance and plant performance modeling, energy modeling, system optimization, and life-cycle cost evaluations to support system selection, project feasibility, and long-term campus planning.
• Support reliability and resiliency requirements typical of mission-critical campuses such as hospitals, data centers, and research facilities, including N+1 and fault-tolerant system designs.
• Provide technical leadership during construction and commissioning, including submittal reviews, RFIs, site observations, and functional performance testing support.
• Coordinate closely with electrical, controls, civil, structural, and architectural disciplines, as well as electric utilities, air permitting and environmental consultants, and equipment OEMs, to ensure integrated power and central plant solutions.
• Interface directly with clients, facilities stakeholders, and operators to align designs with operational requirements and long-term maintenance strategies.
• Mentor junior engineers and review technical deliverables to ensure quality, consistency, and adherence to best practices.
• Ensure compliance with applicable codes, standards, and guidelines (ASHRAE; ASME B31.1 and BPVC Section I; NFPA 37, 54, and 85; EPA and state air permitting requirements; and local jurisdictional requirements).

REQUIRED QUALIFICATIONS

• Bachelor's degree in mechanical engineering or related discipline (Master's degree preferred).
• Minimum of 12 years of progressive mechanical engineering experience, with a strong focus on on-site power generation (CHP, combustion turbines, and reciprocating engines) and central utility plants.
• Proven experience designing on-site power generation, central utility plants, and distribution systems for hospitals, university campuses, utilities, data centers, or similar institutional facilities.
• In-depth knowledge of combustion turbines, reciprocating engines, heat recovery steam generators, boilers and steam systems, fuel gas systems, chiller technologies, pumping configurations, heat rejection systems, thermal energy storage, and plant controls integration.
• Proficiency with engineering design and analysis tools, including load calculation software, hydraulic modeling tools (e.g., AFT Fathom/Arrow), plant performance modeling (e.g., Thermoflex/GT PRO), pipe stress analysis (e.g., CAESAR II), and AutoCAD/Revit/Plant 3D.
• Professional Engineer (PE) license in the United States required.
• Strong written and verbal communication skills with the ability to present complex technical concepts to non-technical stakeholders.

PREFERRED QUALIFICATIONS

• Experience with campus master planning and phased utility plant expansion.
• Experience with CHP and microgrid projects, including utility interconnection and air permitting support.
• Owner's engineer, design/build, or EPC project experience.
• Familiarity with commissioning, retro-commissioning, and operational optimization of central utility plants.
• Experience supporting mission-critical facilities with high uptime and redundancy requirements.
• Knowledge of energy efficiency, decarbonization, and low-carbon campus utility strategies, including heat recovery chillers, heat pumps, hydrogen-ready turbines, and battery energy storage integration.

KEY COMPETENCIES

• Technical leadership and independent engineering judgment
• Systems-level thinking with a focus on reliability and resiliency
• Cross-disciplinary collaboration and stakeholder engagement
• Mentorship and quality control of engineering deliverables
• Client-focused, solutions-oriented mindset
