The Stellar Group
Overview
Senior Mechanical Engineer position in Jacksonville, FL. The role involves designing mechanical systems for buildings and support systems for food processing plants and warehouses, including utilities, HVAC, and plumbing. Fire protection design experience is a plus. The engineer will participate from concept through construction documentation and administration, guiding junior engineers and designers and collaborating with cross-functional teams. Responsibilities
Design utilities systems that supply fluids and gases to building and process users via pressure piping systems (steam generation and distribution, hot water heating and distribution, compressed air, chilled water, chilled glycol, cooling tower water, cold water distribution, water pressure boosting, pumping, natural gas, and nitrogen). Size utilities equipment and piping distributions using owner/process data, restroom fixture demands, metering data, HVAC and refrigeration needs, and engineering judgment for diversity and safety factors. Produce utilities pipe material and insulation schedules and coordinate with vendors to select equipment and prepare equipment schedules for drawings. Include controls sequence of operations write-ups or controls expectations on utilities equipment schedules. Design plumbing gravity drainage systems (sanitary, storm, and process waste) with venting, isometric riser diagrams, and pipe/fixture schedules. Design HVAC systems (rooftop equipment, split systems, 100% outside air, exhaust, heat pumps) using DX refrigerants, chilled water/glycol, natural gas, and steam as applicable. Size HVAC equipment by loads, and size associated ductwork using velocity and pressure drop calculations; prepare ductwork schedules with vendors. Include HVAC controls sequencing of operations, pressurization, and hygienic zoning. Produce drawings using Revit (3D) and, occasionally, AutoCAD, or supervise Designers/Engineers on the project team. Collaborate with cross-functional teams (architects, civil, electrical, structural, process engineers, project managers, owners, etc.). Conduct building assessments and feasibility studies to evaluate design options for clients. Equipment pricing may be provided by vendors; installation pricing is handled by others. Adhere to project timelines and budgets. Manage conceptual development, detailed design, calculations, construction-level documents, Revit production oversight, RFIs, shop drawings, submittals, site visits, and record drawings. May require independent work or team leadership while ensuring quality and schedule adherence. Conduct inter-discipline coordination, BIM clash detection, and site inspections. Fire protection design experience is a plus; sizing and selection of sprinklers, fire pumps, and tanks using hydraulic calculations and related software is a plus. Other duties as assigned. Required Skills/Abilities
In-depth knowledge of mechanical engineering principles and codes/standards (ASME, ASHRAE, IMC, IPC, IFGC, IECC, etc.). Excellent verbal and written communication; strong interpersonal skills for teamwork with clients and stakeholders. Ability to work independently and as part of a team; prioritize tasks and meet milestones. Ability to analyze and interpret technical data and drawings; strong problem-solving and critical-thinking skills. Proficiency with mechanical engineering software and Microsoft Office (Excel, Word, Teams, Outlook). Attention to detail and a commitment to high-quality work; strong leadership and mentoring capabilities; highly organized with multi-project management ability. Education/Experience
Bachelor's degree in Mechanical Engineering required; current P.E. license preferred. Minimum of 10 years of mechanical engineering design experience; experience in industrial facilities or food and beverage is preferred. Basic capabilities in AutoCAD and Revit (pan/zoom); modeling proficiency preferred. Travel Requirements
Flexibility to travel on short notice for urgent business needs, meetings, trainings, and events. Physical Requirements
Ability to sit, stand, and walk for long periods; use of computer and office equipment; visual acuity for detailed work. Ability to lift up to 25 pounds; climb stairs and/or ladders. About Stellar
