Assembly Mechanic Job Description Template
1. About the Role
An Assembly Mechanic builds, inspects, and certifies mechanical components before they enter service. The role covers the full build sequence for pumps, hydraulic cylinders, and related rotating equipment in industrial and mining markets, from raw material preparation through final pressure and dimensional testing. Shop floors in these sectors hold equipment to OEM reusability standards, so the person in this seat makes formal fitness-for-service judgments that determine whether a part is remanufactured or replaced. That judgment carries direct cost and safety consequences for the operations that depend on the equipment.
2. Position Summary
As the Assembly Mechanic, you own the hands-on build and inspection cycle for industrial mechanical equipment, delivering components that meet documented quality and safety standards before leaving the shop. You work within a manufacturing or repair facility, coordinating with machinists, service mechanics, and supervisors to move work orders from material preparation through final inspection and production documentation.
3. Why Join Us
Career Impact: Hands-on experience with pump and hydraulic cylinder assembly, combined with proficiency in reading engineering drawings and applying OEM standards, builds a credential set that is consistently valued across industrial, mining, and energy sector employers.
Business Impact: When an Assembly Mechanic accurately assesses component reusability and documents corrective actions, operations teams avoid unplanned equipment failures and the production losses that follow a misclassified part entering service.
Growth Opportunity: Mastery of precision measurement, crane and forklift operations, and production order systems creates a direct path to senior mechanical technician, shop lead, and field service roles within industrial equipment companies.
4. Key Responsibilities
- Assemble and disassemble pumps or hydraulic cylinders in the shop, following engineering drawings and documented assembly procedures.
- Conduct water testing, hydro testing, and dimensional inspections of completed assemblies to verify they meet quality standards.
- Determine component reusability against OEM and internal quality standards, writing clear work order instructions for machinists remanufacturing damaged parts.
- Prepare materials for assembly including surface treatment, pre-paint and post-paint prep, and staging in the clean and prep area.
- Monitor and record labor and materials for each production order, completing required production system transactions upon operation completion.
- Support 5S activities daily by maintaining equipment, tools, and work areas in accordance with shop housekeeping standards.
- Identify the root causes of mechanical and electrical component failures and recommend corrective actions to supervision.
- Adhere to all health, safety, and environmental policies, identifying non-compliance situations and escalating for resolution.
5. Required Qualifications
- High school diploma, GED, or equivalent combination of trade school training and work experience.
- 1 or more years of mechanical assembly or repair experience, with demonstrated ability to work from engineering drawings and schematics.
- Mechanical aptitude sufficient to apply mathematics when interpreting prints, calculating tolerances, and solving assembly problems.
- Ability to operate precision measuring instruments including calipers, micrometers, bore indicators, and dial indicators.
- Basic understanding of electrical fundamentals as they apply to mechanical and electromechanical pump or cylinder systems.
- Ability to communicate clearly in English, both verbally and in writing, to follow and issue work instructions accurately.
- Demonstrated attention to detail and ability to follow meticulous, step-by-step assembly and inspection procedures.
6. Preferred Qualifications
- Experience with vertical and horizontal pump assembly or hydraulic cylinder teardown, with crane lift rigging certification considered an asset.
- Forklift certification or documented ability to complete forklift training within a defined onboarding period.
- Familiarity with ERP or production order systems used to confirm operations and track material consumption at the work order level.
- Prior exposure to 5S, lean manufacturing, or structured shop-floor improvement programs in an industrial or heavy-equipment environment.
7. Success Metrics & Environment
- Work order completion rate, measuring the percentage of production orders closed on time against the shop schedule.
- First-pass inspection pass rate, reflecting how often assembled components meet quality standards without rework.
- OEM reusability judgment accuracy, tracked by the rate of downstream rework attributable to misclassified components.
- Safety incident rate within the assigned work area, measuring adherence to lockout/tagout and PPE protocols.
- Inventory accuracy contribution, measured by discrepancy rate found during audits of parts pulled or stocked under this role.
- Typical tools: precision measurement instruments (commonly calipers, micrometers, bore indicators); production documentation systems (commonly SAP or equivalent ERP)
8. Compensation & Benefits (US Market Benchmark)
- Base Salary Range: $38,000 to $58,000 annually, depending on experience and facility location
- Bonus: Spot bonuses or shift differential pay common in manufacturing environments
- Equity: Typically not offered at this level in industrial manufacturing
- Health Benefits: Medical, dental, and vision coverage; employer contribution varies by company size
- PTO: 10 to 15 days annually, plus standard US federal holidays
- Common Perks: Tool allowances, safety boot reimbursement, and employer-paid trade certifications
