Contract Wireless Design Engineer Jobs in Indiana



Location: Fishers, IN

We are seeking a Mechanical Design Engineer to join a dedicated in‑house engineering group responsible for HVAC system design and limited plumbing design support. This position supports design‑build project delivery, working directly alongside internal fabrication, installation, BIM, and electrical teams to develop efficient, constructible mechanical systems.

Unlike traditional plan/spec engineering roles, this position offers direct involvement in design/bid and design‑build work, allowing engineers to maintain technical authority while benefiting from streamlined project coordination and accelerated design cycles. The engineering team plays an integral role throughout project execution, from concept development through construction support.

• Develop HVAC system designs and construction documents, including drawings and specifications, for commercial, institutional, and industrial facilities
• Perform heating and cooling load calculations using Trace or similar software and evaluate system options based on performance, constructability, and project requirements
• Select mechanical equipment and systems; size ductwork, hydronic piping, and plumbing components
• Coordinate with equipment manufacturers and vendors to develop compliant, site‑specific design solutions
• Conduct field surveys and existing conditions assessments in support of proposals and active projects
• Contribute to project planning by adjusting design approaches and supporting detailed design phases
• Prepare, review, and verify engineering calculations, reports, and technical documentation
• Coordinate mechanical designs with other disciplines using Revit and Navisworks, resolving clashes and constructability concerns
• Provide ongoing coordination and technical support throughout the design and construction process

• 4+ years of mechanical engineering experience (HVAC or plumbing systems)-
• If a candidate is lighter in HVAC/Plumbing experience here they need to make up for it with strong Revit or technical experience
• Revit design proficiency
• Ability to work in a fast paced environment
• Ability to coordinate between disciplines on the design

Nice-to-Haves:

• Commercial and industrial systems experience is preferred
• Experience from design consulting firms is also preferred

• Industrial and manufacturing facilities
• Warehouse and tenant improvement projects
• Commercial buildings including higher education, K‑12, hospitality, office, and large food service facilities

This role is part of a fully integrated engineering organization where design decisions directly inform fabrication and installation. Engineers benefit from close collaboration with BIM specialists, electrical engineers, and construction teams, resulting in practical, efficient designs and reduced rework. The organization emphasizes technical rigor, coordination efficiency, and accountability across disciplines.

• In‑house engineering team with direct influence over constructability
• Integrated design‑build delivery supporting faster project execution
• Exposure to a diverse range of building types and mechanical systems
• Technically focused environment with strong cross‑discipline collaboration
• Stable backlog of work and long‑term investment in engineering resources
