About the rolePlenty is looking for a Senior Staff Mechanical Design Engineer experienced in the design and construction of HVAC and thermal systems in mission critical and/or manufacturing applications to become part of our Engineering team. Our mission is to build and operate efficient, reliable and cost effective indoor farms which are essential to Plenty’s growth.In this role, you will own and manage end-to-end design, construction and operation of our farm mechanical and other support systems. You will be responsible for providing strategic leadership for a high impact infrastructure with technical complexity, while also being a technical lead/individual contributor for the Mechanical discipline. You will contribute deep knowledge and subject matter expertise related to HVAC and thermal systems including leading the design, modification, analysis, and supporting operation for our new and existing farms.

What you'll doCollaborate with internal stakeholders to define project criteria to meet Plenty business and technical needs. This includes defining scope, specifying technical requirements as part of design criteria/ basis of design, and long lead equipment specification development, etc. for the Consultant/Contractor to develop project specific contract/construction documentation. Manage external consultants/contractors to implement project requirements from concepts through contract/construction documents, and construction administration Research new technologies related to HVAC design, equipment selection, and construction methods to drive innovation. Perform independent engineering and cost analysis, including but not limited to calculations of HVAC loads, system energy-use, and process gas demand, etc. Lead conceptual designs with Mechanical Engineering of Record (EOR) to ensure design options have been evaluated/vetted prior to proceeding with the final design option. Conduct reviews of consultants’ engineering calculations, design drawings and specifications to identify design and scope gaps to minimize change orders in the field.Review Contract/construction documentation including, but not limited to, building automation/management system design, including sequences of operation, instrumentation selection, process and instrumentation diagrams (P&IDs) and panel drawingsCoordinate with contractors, equipment manufacturers, and commissioning agents in collaboration with Consultants/EORs to ensure proper equipment selection, quality installation, commissioning and testing to meet design intents.Manage mechanical OFCI equipment/systems including leading technical requirement reviews with vendors, conducting specification compliant reviews and bid leveling with assistance from the Plenty Supply Chain team, and conducting factory witness testing.
