Senior Mechanical Engineer

The Senior Mechanical Engineer will be responsible for the design of mechanical systems as part of a team that designs buildings and support systems for food processing plants and warehouses. The candidate will be responsible for the design and specification of utilities, HVAC, and plumbing systems. Any fire protection design experience will be a plus. You will work on projects from concept to issuing of construction drawings through construction administration efforts such as the review of equipment submittals and technical support. This position involves advanced technical knowledge, project management skills, and leadership abilities to guide junior engineers and designers collaborating with cross-functional teams. ### Duties/Responsibilities: - Design Utilities systems that supply fluids and gases to the building and process users via pressure piping systems. Systems commonly designed include steam generation and distribution, hot water heating and distribution, compressed air, chilled water, chilled glycol, cooling tower water, cold water distribution, water pressure booster packages, low/high pressure water pumping, natural gas, and nitrogen. - Size Utilities equipment and piping distribution systems by totalizing the loads from data available from owner/process provided equipment needs, hot/cold water requirements for restroom fixtures, analysis of metering data, HVAC and refrigeration equipment needs, and using engineering judgement for diversity or appropriate safety factors. - Produce Utilities pipe material and insulation schedules and work with vendors as required to select equipment and produce equipment schedules for the drawings. - Utilities design is to include controls sequence of operations write ups and/or controls expectations on the utilities equipment schedules. - Design Plumbing gravity drainage systems such as sanitary, storm, and process waste. This will include venting, isometric riser diagrams, pipe and fixture schedules. - Design HVAC systems that commonly use rooftop equipment, split systems, 100% outside make up air, exhaust systems, and heat pumps. The use of DX refrigerants, chilled/glycol, natural gas, and steam are commonly used for the units. - Size the HVAC equipment by totalizing the loads from data available from the owner/process provided equipment needs, and calculating the cooling and heating loads using internal load spreadsheets and load estimating software such as Trane Trace or IESVE. Size any associated ductwork by doing velocity and pressure drop calculations. - Produce HVAC ductwork material and insulation schedules and work with vendors as required to select equipment and produce equipment schedules for the drawings. - HVAC design is to include controls sequencing of operations, pressurization and hygienic zoning. - Produce drawings using Revit 3D modeling software (occasionally AutoCAD) or oversee Designers/Engineers assigned to the project team to produce the drawings. - Collaborate with cross-functional teams, including architects, civil engineers, electrical engineers, structural engineers, process engineers, design project managers, construction Project managers, owners, etc. - Conduct building assessments and feasibility studies to evaluate design options for clients. This may include equipment pricing from vendors, but installation pricing would be performed by others at Stellar. - Adhere to project timelines and budgets. - The candidate will be responsible for conceptual development, detailed design, calculations, construction level documents, oversight of Revit production resources, responding to RFIs, shop drawing and submittal review, site inspection visits, and record drawings. The role at times may require independent work or the need to manage team members assigned to their projects, while ensuring project requirements, schedule, and overall document quality are met. Inter-discipline coordination, BIM clash detection, and site inspections will be required. The can…
