Designs and manufactures specialty purpose‑built vehicles and equipment for defense, fire, access, refuse and aviation.
The Senior Controls Engineer works in the Sustaining Engineering organization to support, maintain, and enhance control systems across all Ground Support Equipment (GSE) product lines. The role emphasizes hands‑on hardware and software controls design, troubleshooting, and implementation for production, obsolescence management, and customer‑driven product options. The engineer owns smaller projects or subsystems of limited complexity and progressively assumes greater technical ownership with limited supervision.
Key duties include designing, modifying, and supporting low‑voltage (24 V DC) hardware and software control systems for GSE products, preparing accurate automotive software and electrical hardware designs, and documenting operation instructions, test procedures, and validation results. The engineer leads or participates in validation efforts and design reviews, supports sustaining engineering by troubleshooting production issues, resolves obsolescence challenges, and implements design changes. Project ownership typically involves managing up to two small‑scale projects concurrently while collaborating closely with mechanical, electrical, hydraulic, and software engineering teams to ensure timely integration of new options and modifications. Additional responsibilities cover assembly and test assistance, monitoring project status, reporting progress and obstacles, and providing limited mentorship to entry‑level engineers or technicians.
Minimum qualifications are an accredited Bachelor’s degree in Engineering (Electrical preferred) and at least three years of related engineering experience, including hands‑on design or support of electrical control systems, low‑voltage DC expertise, and familiarity with CAN or similar vehicle communication protocols. Preferred qualifications include experience in sustaining engineering or production environments, proficiency with Codesys or comparable PLC platforms, mobile equipment electrical hardware and software design, exposure to electrified or hybrid vehicle systems, and knowledge of battery technologies. The role also values the ability to collaborate with mechanical and hydraulic engineering disciplines and to replace obsolete components with new hardware integrations.
The position requires frequent standing, walking, typing, and occasional lifting of up to 25 lb, with occasional driving and manual dexterity tasks. Travel is minimal but may include domestic and international trips. The work schedule follows routine shift hours with infrequent overtime, weekends, or shift rotation, and the role may involve variable workloads and intermittent periods of increased demand.
The salary range for this role is $79,300 – $126,900, reflecting a competitive total rewards package within a people‑first culture that emphasizes growth and impact.
