Job Description

Senior Application Engineer – Industrial HVAC (Air Handling Units)

Location: Marion, OH (USA) (1 day in office)

Company Overview:

Our client is a global leader in the design and fabrication of advanced industrial air handling units using Off-Site Manufacturing (OSM) technology.

Their integrated approach ensures equipment delivery aligned with the project’s progress. It enables us to shorten overall project timelines, enhance product quality, reduce on-site manpower requirements, and minimize safety incidents — delivering true value beyond the product itself.

Their multidisciplinary expertise spans structural, mechanical, hydronic, electrical, instrumentation & control (I&C), safety, and commissioning.

Position Overview:

They are seeking a skilled and motivated Application Engineer with a background in HVAC systems, specifically in Air Handling Units (AHUs). The ideal candidate will bring at least 3 years of experience in HVAC design, construction or MEP subcontractor projects/works.

Our client is looking for an engineer who will add value to their engineering process and strengthen their value proposition to customers in the US. Their mission is to deliver more than a product — they provide value-driven solutions that optimize efficiency, performance and sustainability.

Key Responsibilities:

• Gain a detailed understanding of their products, technologies and capabilities to effectively translate them into customer solutions.
• Engage with customers to understand their requirements and translate them into customized concepts, aligning technical feasibility with customer value.
• Develop concept solutions, present them for customer approval, and once approved, forward them to the pricing team for costing and proposal preparation.
• At the purchase order (PO) stage, ensure seamless handover to the engineering team, including all approved concepts and project details.
• Manage the submittal process, reviewing technical documentation, drawings, and data sheets to ensure compliance with specifications and customer expectations.
• Provide technical support for the design, selection, and application of both standard and custom-made AHUs, including OSM solutions.
• Review and interpret HVAC design, P&ID schemes, drawings, specifications, and project requirements to develop accurate, project-specific air handling solutions.
• Coordinate with design consultants, contractors and internal teams to ensure compliance with project standards and client expectations.
• Conduct site visits when required, to provide technical guidance and resolve installation or operational issues.
• Stay updated with HVAC technologies, codes and standards (ASHRAE, SMACNA, ISO, etc.) to ensure best practices are applied.

Complex Solutions Scope (Familiarity Required)

• Mechanical design and thermodynamic calculations for AHUs and HVAC systems.
• Structural and seismic design considerations for complete AHU systems.
• Equipment selection for performance and efficiency.
• Electrical panel design and fabrication requirements.
• P&ID (Piping & Instrumentation Diagram) understanding and development.
• Instrumentation & Control (I&C) panels design and fabrication requirements.
• Factory acceptance testing and commissioning processes.

Qualifications & Experience

• Bachelor’s Degree in Mechanical Engineering or equivalent.
• Minimum 3-4 years of relevant experience in HVAC design, construction or MEP subcontractor projects/works.
• Strong knowledge of HVAC system design principles with proven expertise in Air Handling Units.
• Experience in customer-facing roles involving concept development, technical presentations, or submittal processes.
• Broad understanding of multidisciplinary engineering fields (mechanical, structural, electrical, controls, commissioning) and ability to coordinate with specialized teams.
• Ability to work with AutoCAD, Revit, SolidWorks and Navisworks, with familiarity in BIM modeling workflows and coordination.
• Excellent problem-solving, communication, and coordination skills.
• Ability to manage multiple tasks and work under tight deadlines.
