This is an individual-contributor role by design - best suited to someone motivated by deep technical mastery. * Deep hands-on diesel engine experience is strongly preferred (Cummins in particular). * Genuine hands-on "gearhead" experience integrating diesel subsystems (cooling, fuel, exhaust/aftertreatment, intake, lubrication, sheet metal and general component placement). * Strong understanding of diesel engine performance, duty cycles, and system-level operation. * Knowledge and experience with applicable regulations, including: DOT, Environmental, UL, emissions (EPA Tier 4 final, EU Stage V, CARB). * Working understanding of diesel engine control and electrical systems, enough to define high-level requirements and work effectively with controls and electrical engineers. * Must have a valid driver's license and the ability to travel up to 10% to job sites. Preferred Skills: * Advanced 3D CAD modeling (CREO, Windchill, or equivalent); skilled in assembly, detailed drawings, sheet metal, and enclosure design. * Prior experience with portable, skid-mounted, or trailer-mounted diesel-driven equipment (compressors, generators, or similar mobile machinery) serving industrial applications. * Strong background in thermal, vibration, and acoustic system analysis, including exposure to hydraulic-driven cooling fan systems (legacy platforms); comfortable joining a growing team and helping build out design and release processes rather than expecting them fully defined. * Excellent communication and organizational skills with a customer-first focus. * International exposure (Europe, Asia, or other global markets) a plus, though deep expertise is not required. * Proficient in Microsoft Office Suite (Excel, Word, Outlook). ## Description The Sr. Design Engineer, Diesel Integration leads the mechanical and system-level integration of diesel powerplants into Rogers Machinery's portable air compressor product line. This role owns the engine-to-package design - cooling, exhaust, fuel, and structural/enclosure integration - ensuring every diesel-driven unit performs reliably in the field. This is a hands-on, technically driven individual-contributor role. Works closely with the controls and electrical teams supporting each design. Must be able to work under minimal supervision of the department manager., * Define product scope via sales order, rough sketches, or verbal instructions. * Develop and validate engine-to-system integration layouts for portable air compressor packages, including cooling, intake, exhaust/aftertreatment, fuel, lubrication, and control systems. * Verify diesel engines are properly matched to compressor and driven equipment, considering power curves, duty cycles, load requirements, and environmental/field conditions, drawing on diesel engine platform experience (Cummins preferred; CAT and Volvo a plus). * Develop design solutions for thermal management, vibration, and sound dampening; conduct system-level analysis and verification. * Design and integrate enclosure, sheet metal, and structural components that house and protect the diesel powerplant within the portable package. * Develop and manage product designs, schematics, validation procedures and testing. * Manage BOMs, validation reports, and compliance requirements on diesel-powered products. * Collaborate with controls and electrical engineers to define engine, controls, and electrical requirements and integrate them into the package design. * Support and conduct system-level troubleshooting of engine operation within the equipment, including load response, transient performance, and fault detection. * Lead design release process, certification testing, and production release. * Coordinate and manage simultaneous projects, sustaining and new product development. * Act as a diesel integration ambassador by defining and promoting best practices and standards for integrating diesel powerplants into portable industrial equipment. Additional Job Duties: * Support production, field commissioning, and troubleshooting of diesel-powered installations. * Define retrofit kits, system upgrades, and modifications to ensure performance or lifecycle across the powerplant lineup. * Provide support for sales, service, cost estimates, design consultation, and installations. * Identify alternate integration methods or components to reduce cost, lead time, or supply risk. * Provide guidance and training to junior team members and supporting departments.
