About the role

As our Senior Mechanical Engineer, you will be part of the Engineering Team within the Capital Projects structure and report to the Director of Engineering. This role leads and delivers all aspects of engineering scope related to operations and maintenance of existing assets and design, specification, and engineering of new capital and brownfield projects. You will conceptualize and front-end engineer designs, which, once validated, are provided to external detailed design engineering and installation contractors, utilities, permitting authorities, clients, and building owners. The position also serves as a liaison with other technical centers of excellence within the global ENGIE organization, managing these relationships and engagements.

Responsibilities

• Develop conceptual designs for power, heating, and cooling, including major equipment selection and budgetary capital cost estimates.
• Develop specifications for materials and equipment procurement.
• Review Original Equipment Manufacturer (OEM) equipment configuration to meet technical requirements and achieve the lowest levelized energy cost.
• Provide technical input during Request For Proposals and evaluate OEMs, engineering, and construction companies.
• Be responsible for scoping, contracting, and managing consultants and contractors, when necessary.
• Perform process and performance assessment (e.g., equipment and pipe sizing) of district heating and cooling systems, from production (Combined Heat and Power (CHP), boiler and chiller plants) through distribution to energy transfer stations (ETS) at local end-users.
• Assure detailed design and engineering developed by contractors.
• Deliver required technical support related to permitting.
• Review and develop procedures and witness Factory Acceptance Testing (FAT) for major equipment.
• Participate in HAZID/HAZOP and design reviews.
• Deliver responses to Request for Information (RFI) from the field and collaborate with project management to prioritize RFIs.
• Release engineering documentation as needed, including field change modifications.
• Provide engineering support and planning for utility outages during construction and maintenance activities.
• Collaborate to resolve issues during construction, commissioning, and startup phases.
• Deliver energy system reliability, integrity, and operational excellence on existing assets.
• Conduct technical reviews with internal and external stakeholders as requested.
• Optimize system configurations for design and operations, accounting for various production configurations while ensuring network requirements and key performance indicators (KPIs) are met.
• Develop thermal and hydraulic models of combined heat and power/cogeneration, district energy system assets.
• Model and estimate energy use profiles by energy type, building type, location, and seasonal climates.
• Analyze thermal and electric loads for customers based on historical data, future load projections, and potential energy conservation measures.
• Assist in developing root cause analyses for any operational issues.
• Liaise with members of the Engineering and Shared Services teams utilizing in-house experience and knowledge.

Requirements

• Minimum of a Bachelor's degree in Chemical, Mechanical, or a related engineering discipline.
• Minimum of five (5) years of working experience in design/engineering of power plants and components and district energy systems.
• PE license is a plus but not required.
• Knowledge and experience in thermal engineering related to developing, constructing, and operating District Energy, Utilities, and Combined Heat and Power Systems.
• Demonstrated knowledge of gas turbines and gas engine gensets, heat recovery steam generators (HRSGs), steam turbines, cooling towers, boilers, chillers, heat pumps, pipe distribution systems (steam, low temperature hot water, high temperature hot water, chilled water, ambient temperature, condensate return), and geo-exchange.
• Knowledge of applicable industrial codes and standards – ASME, NFPA, ASHRAE, EN, ISO, and other design codes.
• Software knowledge of thermal design and performance modeling tools such as GT Pro, Gate Cycle, and/or Termis.
• Good verbal and written communication skills, especially when interacting with outside stakeholders.
• Ability to handle multiple assignments with a high degree of accuracy and independence.
• Familiarity with data historians such as OSI PI and Web CTR.
