Roberts Sinto is currently seeking a Field Service Technician – Shot Blast to join our Team in Grand Ledge, MI
What You Will Do
As a Shot Blast Field Service Technician, you are the technical authority and face of Roberts Sinto on customer sites. You will lead the installation, commissioning, calibration, inspection, repair, and full mechanical/electrical rebuilds of both Roberts Sinto equipment and competitive OEM shot blast machines (such as Wheelabrator, Pangborn, Goff, Rosler, and Viking).
Your scope covers the full spectrum of surface treatment equipment—including tumble blasts, monorail and spinner-hanger machines, table blasts, bar and structural descalers, and integrated dust collection systems. This role requires a strong blend of heavy mechanical/millwright aptitude, electrical/PLC diagnostic skill, and customer relationship management. We are looking for an independent problem-solver who can step into high-pressure foundry, forge, and manufacturing environments, execute major machine overhauls, diagnose complex blast system issues regardless of the nameplate, and minimize customer downtime
General
- Full Machine Rebuilds, Retrofits & Modernizations: Lead and execute complete on-site tear-downs, structural and mechanical overhauls, blast wheel conversions, manganese cabinet relining, and control upgrades on both Sinto and non-Sinto OEM shot blast equipment.
- Installation, Commissioning & Run-Off: Lead the on-site mechanical and electrical setup, alignment, and run-off of new or rebuilt shot blast equipment and dust collectors, verifying that systems meet specifications, cycle times, and safety standards prior to handover.
- Blast System Calibration & Optimization: Perform blast pattern testing ("hot spot" checks), adjust control cages and impellers, balance blast wheels, and calibrate abrasive media flow and air-wash separators across various OEM wheel designs for maximum cleaning efficiency and reduced wear-part consumption.
- Multi-Brand Troubleshooting & Emergency Repair: Diagnose and resolve mechanical, electrical, pneumatic, and hydraulic issues across all makes and models of blast wheels, bucket elevators, screw conveyors, rotary screens, work-handling mechanisms, and baghouse/cartridge dust collectors.
- Preventative Maintenance & Inspections: Execute scheduled PM programs and comprehensive machine audits—inspecting manganese/cast wear liners, blast wheel blades, seals, bearings, and separator airlocks to extend equipment life and identify replacement part or rebuild needs.
- Customer Training: Deliver hands-on training to customer operators and plant maintenance teams covering safe machine operation, abrasive media management, blast pattern adjustment, and routine wear-part replacement.
- Reporting & Documentation: Accurately document service visits, machine audit findings, recommended spare/wear parts or rebuild scopes, and expense reports. Familiarity with digital field service tools and ERP systems (such as Infor SyteLine) is a plus.
- Remote Technical Support: Assist customers and internal After-Sales, Spare Parts, and Engineering teams with technical troubleshooting, cross-referencing competitive OEM components, and part identification when not traveling.
What We Want From You
Education & Experience:
- High School diploma or GED required; Associate degree or technical certification in Mechatronics, Industrial Maintenance, Electrical Technology, or a related field preferred.
- Shot Blast & Rebuild Experience: 4+ years of hands-on experience servicing and rebuilding heavy industrial machinery in foundry, metalcasting, forging, steel, or heavy manufacturing environments. Direct experience maintaining, troubleshooting, and overhauling centrifugal wheel blast equipment (Sinto, Wheelabrator, Pangborn, Goff, etc.), abrasive recovery systems, and industrial dust collectors is strongly preferred.
- PLC & Controls Experience: 4+ years of experience troubleshooting industrial electrical controls, 480V 3-phase power, VFDs, motor starters, sensors, and PLCs (Allen-Bradley/Rockwell or Siemens preferred), including adapting to legacy or third-party control panels.
- Proven track record of successful, independent work travel.
Skills:
- Deep root-cause diagnostic capability across heavy mechanical drive systems, high-wear abrasive handling components, pneumatics, hydraulics, and automated controls—even when working on legacy or third-party equipment with limited documentation.
- Strong mechanical rebuilding and rigging/millwright skills, including bearing/shaft replacement, elevator and conveyor overhaul, and cabinet liner/weldment refurbishment.
- Ability to read and interpret electrical schematics, pneumatic/hydraulic diagrams, airflow/ducting layouts, and mechanical assembly blueprints across various manufacturers.
- Strong communication skills with the ability to explain wear trends, rebuild vs. repair recommendations, and technical concepts clearly to plant managers, engineers, and maintenance crews.
- High degree of self-motivation, safety awareness (including LOTO, rigging, and confined space protocols), and ability to work autonomously or lead small rebuild crews on customer sites.
Physical Demands & Work Environment
- Physical: Frequently required to stand, walk, climb ladders/platforms, bend, kneel, and use hands to handle tools and heavy machine components during tear-downs and rebuilds. Regularly required to lift and move up to 50 pounds unassisted. Specific vision abilities include close vision, depth perception, and focus adjustment.
- Environment: Regularly exposed to heavy industrial and foundry conditions, including moving mechanical parts, steel shot/grit abrasive media, airborne dust/particles, confined or elevated workspaces, extremes of heat and cold, high noise levels, and risk of electrical shock.
- Travel: Ability to travel extensively (up to 75%) domestically and occasionally internationally, including multi-day or multi-week stays for major rebuild projects and short-notice dispatches for emergency breakdowns. Must possess a valid driver’s license, a clean driving record, and a valid passport (or ability to obtain one).
