About Us: Koester Corporation, located in Napoleon, OH, has been around for over 50 years, providing engineering services and industry solutions to a wide variety of customers. What started in 1970 building control panels for the foundry industry has grown into a full-service partner with in-house controls engineering, panel building, machining, and fabrication. We are actively seeking a detail-oriented, technically minded Proposal Engineer to join our Electrical Engineering department and support our engineering sales team.
At Koester, we take pride in being a solutions provider. Our customers span material handling, water and wastewater, aerospace, and automotive, so no two projects look the same. As a Proposal Engineer, you will see more of our work than almost anyone in the building, taking each opportunity from customer specs and a sales engineer’s scope to a complete, accurate estimate. This is a great fit for an engineer who enjoys the technical side and wants to learn how projects are won, with a clear path toward sales engineering or project engineering.

Develop Bills of Material and Pricing:
- Build panel and field device bills of material from the sales engineer’s scope and preliminary designs.
- Request and track vendor and distributor quotes for components, panels, and subcontracted work.
- Maintain current material pricing and lead times.
Prepare and Track Proposals:
- Assemble proposal documents including scope of work, clarifications, exclusions, and schedule.
- Maintain the quote log and track the status of open quotes.
- Support the engineering and the sales engineer with quote revisions and customer follow-up.
Work with Engineering and Our Panel Shop:
- Collaborate with project engineers and the panel shop to validate labor estimates and design assumptions.
- Occasionally join site walks with the engineers or sales engineer to gather scope information.
Improve Our Estimating Process:
- Compare quoted versus actual hours and materials on completed projects and feed the results back into our estimating standards.
- Help build and maintain our quoting templates and pricing database.
Minimum Qualifications:
