Senior Mechanical Engineer/Project Manager

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Mechanical Engineer/Project Manager based in the United States. As a Senior Mechanical Engineer/Project Manager, you will lead the design and delivery of complex mechanical systems for mission-critical facilities and building projects. You will oversee engineering activities from early design through construction documentation, ensuring technical excellence, code compliance, and alignment with project objectives. Working with multidisciplinary teams, clients, vendors, and contractors, you will develop practical solutions that meet demanding performance and reliability requirements. Your expertise will help shape mechanical infrastructure for critical environments, including data centers, telecommunications facilities, and other specialized buildings. You will combine advanced mechanical design knowledge with project management, quality assurance, and technical leadership across multiple concurrent projects. This role offers the flexibility of remote work while requiring occasional site visits and in-person client meetings in California and other relevant locations. You will also mentor engineering and design professionals, manage project resources, and help deliver high-quality outcomes within established budgets and schedules. Accountabilities: You will lead mechanical engineering design and project delivery, ensuring that technical solutions meet client requirements, applicable codes, quality standards, and project constraints. Your responsibilities will include: - Lead mechanical design: Develop, review, and coordinate mechanical systems and CAD drawings throughout schematic design (SD), design development (DD), and construction documentation (CD) phases.

- Manage project delivery: Coordinate multiple projects, establish work plans, monitor deliverables, manage budgeted hours, and ensure milestones are achieved on schedule. - Develop engineering documentation: Prepare and review load calculations, specifications, scope-of-work narratives, basis-of-design documents, studies, reports, sketches, and other technical deliverables. - Design mechanical systems: Apply expertise in chilled water (CHW), hot water (HW), condenser water, steam, water-source heat pumps, variable- and constant-flow systems, and other building HVAC applications. - Select and evaluate equipment: Perform advanced equipment selection and analysis for chillers, boilers, cooling towers, air terminals, air valves, heat filters, direct-expansion (DX) equipment, fans, coils, and water-source heat pumps. - Apply HVAC engineering principles: Design and evaluate air-side systems, including constant-volume (CV) and variable-air-volume (VAV) systems, as well as hydronic systems and associated equipment. - Analyze building performance: Apply psychrometric principles, total-energy concepts, and an understanding of humid-climate design risks to develop effective mechanical solutions. - Ensure code compliance: Interpret and apply relevant building and mechanical codes, review code-related design elements, and ensure documentation meets regulatory and project requirements. - Coordinate multidisciplinary teams: Collaborate with mechanical, electrical, plumbing, fire protection, architectural, and structural professionals, as well as project coordinators, project managers, clients, and vendors. - Resolve construction issues: Respond to requests for information (RFIs), review submittals, address installation challenges, and manage revisions, including architect's supplemental instructions (ASIs), using established documentation conventions. - Maintain quality and manage risk: Conduct quality assurance and quality control (QA/QC) reviews of calculations, drawings, and specifications while applying risk management practices to protect project and client interests.
