• Maintain high quality standards by following established processes, inspecting your own work, and ensuring each assembly meets specifications before moving to the next step.
• Adhere strictly to all safety procedures, including consistent use of required personal protective equipment (PPE) and safe operation of tools, cranes, and lifting devices.
• Participate in training and assessments focused on safety, fastening, sealing, hydraulic equipment, torque equipment, and quality, and apply this knowledge on the job.
• Contribute to a clean and organized work area by following 5S and housekeeping practices, minimizing debris such as metal scraps, packaging, and oil spills.
• Support production schedules, including working assigned shifts and overtime as needed, such as every other Saturday when required.
• Use computer skills to access work instructions, engineering drawings, and process documents, and to record production and quality information accurately.

• Proven experience working in an industrial environment with hands-on mechanical tasks.
• Demonstrated experience using mechanical tooling such as torque equipment, DC tools, hand tools, and pneumatic tools.
• Mid-level mechanical aptitude, with the ability to understand how mechanical systems fit and function together; this is not an entry-level or basic power tools role.
• Experience following written work instructions, SOPs, blueprints, or similar technical documentation.

• Reliable attendance and the ability to follow established call-off procedures when necessary.
• Ability to work effectively in a team environment, often paired with another assembler on shared tasks.
• Ability to meet physical demands of the role, including standing for long periods and handling tools and components throughout the shift.
• Willingness and ability to wear required PPE, including steel or composite toe shoes, earplugs, and safety glasses at all times on the production floor.
• Steel-toed or composite-toed shoes required at the start of employment.
• No diploma required for consideration for this role.

• Experience in industries such as automotive repair, diesel technician work, lube technician roles, tire shops, farming, construction, maintenance, or facilities.
• Background in mechanical assembly, automotive repair, industrial maintenance, or light industrial production.
• Familiarity with reading and interpreting mechanical blueprints and electrical schematics.
• Experience with torque tools and understanding of how to verify that assemblies are correctly torqued.
• Experience with pneumatic tooling and ability to explain proper use and applications.
• Hands-on experience building or assembling equipment, vehicles, machinery, or projects from scratch using tools.
• Experience with troubleshooting mechanical issues in a professional or personal setting.
• Exposure to electrical or electronic assembly, wiring, or use of electrical testing equipment.
• Comfort working in a production or assembly line environment while maintaining quality and safety standards.
• Ability to describe and follow quality standards and processes used in previous roles to ensure good parts or products.
• Capability to walk through step-by-step processes for building or assembling items, demonstrating structured thinking and process orientation.
• Ability to score at or above the required percentile on a general labor or mechanical aptitude assessment, as specified by the hiring process.

Work Environment

The role is based in a large, temperature-controlled manufacturing facility that is divided into an assembly side and a machine shop side. The environment is clean and organized, with minimal debris such as metal scraps, packaging, or oil spills, reflecting a strong safety culture. Assemblers typically work in two-person teams within one of several zones on the main line, often working side by side on multiple components such as oil pumps and coolers, with job times varying by area. The work involves frequent use of torque wrenches, pneumatic air tools, DC (electrical) tooling, hand tools, cranes, and lifting devices, with access to a tool area that contains more than 40 tools at each station. Required PPE includes steel or composite toe shoes, earplugs, and safety glasses, with earplugs and glasses provided on-site. The facility enforces strict PPE compliance and operates as a tobacco-free campus, allowing the use of tobacco products only during approved breaks in personal vehicles in the parking lot. The dress code is relaxed but work-appropriate: sweatshirts, t-shirts, hats, work pants, and jeans are acceptable, while leggings and sweatpants are not. Multiple shifts are available, including 1st shift (6:30 a.m.–2:30 p.m.), 2nd shift (2:30 p.m.–10:30 p.m.), and 3rd shift (10:30 p.m.–6:30 a.m.), as well as alternative weekend schedules such as 6:00 a.m.–6:00 p.m. or 6:00 p.m.–6:00 a.m. on Friday, Saturday, and Sunday.
