Core Responsibilities

Primary Functions

Receive, inspect, and verify incoming components and kits against packing lists, purchase orders, and BOMs (bill of materials) to confirm part numbers, quantities, and condition before routing to assembly or storage areas.
Accurately assemble mechanical subassemblies and finished products according to detailed work instructions, assembly drawings, and SOPs, ensuring all fasteners, spacers, seals, and components are installed to specification.
Perform kitting tasks: pick and collate parts for production runs or customer orders, label kits with lot numbers and expiration codes when applicable, and stage kitted materials for efficient production flow.
Operate hand tools and power tools (screwdrivers, torque wrenches, rivet guns, pneumatic tools) safely and to specified torque and fastening values to ensure consistent assembly quality.
Conduct in-process visual and dimensional inspections using calipers, micrometers, go/no-go gauges, and check fixtures to verify tolerance conformance and identify nonconforming parts early in the build process.
Package finished assemblies securely, applying protective materials, dunnage, and standardized labeling (UPC, SKU, handling icons) to meet shipping and customer packaging specifications.
Use warehouse management systems (WMS), RF scanners, and pick/pack software to confirm picks, record completed assemblies, update inventory, and print batch/lot labels in real time.
Perform functional tests and basic electrical/mechanical checks on assembled units (where applicable), logging test results and reporting intermittent failures to the quality or engineering teams for root cause analysis.
Follow first-in, first-out (FIFO) and lot tracking procedures to ensure proper material flow and traceability for serialized or lot-controlled components and finished goods.
Participate in daily production huddles and shift changeovers to coordinate priorities, report production status, and identify material shortages or quality issues that impact throughput.
Maintain a clean, organized workbench and assembly area, disposing of scrap appropriately, replenishing consumables, and performing daily 5S activities to support safety and efficiency.
Report and document any damaged, defective, or nonconforming materials discovered during receiving or assembly and initiate appropriate corrective action requests or rework as directed by QA.
Collaborate with shipping/receiving to stage completed orders, verify pick slips, prepare manifests, and ensure outbound shipments meet carrier and customer requirements for labeling and documentation.
Assist in cycle counts, physical inventory audits, and reconciliation of discrepancies between WMS records and physical stock, providing supporting documentation for adjustments.
Adhere strictly to PPE and safety protocols (lockout/tagout when applicable, hazardous material handling, ergonomics) to reduce workplace injuries and maintain OSHA compliance.
Set up and tear down workstations for new jobs, perform minor equipment adjustments, change tooling or fixtures between product runs, and coordinate with maintenance for more complex repairs.
Read and interpret engineering drawings, assembly diagrams, and specification sheets to determine sequence of operations and required tolerances for complex assemblies.
Support continuous improvement initiatives by documenting assembly inefficiencies, suggesting process improvements, and participating in Kaizen, 5S, or Lean events to reduce cycle time and waste.
Ensure accurate lot and serial number tracking by affixing barcode labels, entering serial data into the WMS or ERP system, and maintaining traceability for warranty and service support.
Train and coach new assemblers and temporary staff on standard operating procedures, quality expectations, and safety practices to accelerate onboarding and maintain production standards.
Monitor work orders and production schedules, escalate material shortages or machine downtime to supervision, and assist in reprioritizing assemblies to meet customer delivery dates.
Perform basic soldering, wiring, or cable routing tasks when required by product specifications, following IPC or company-specific soldering and wiring standards.
Support seasonal or peak shipping periods by cross-training into packing, order staging, and palletizing to maintain service levels and throughput.
Document production metrics such as units completed, rework rates, scrap quantities, and downtime reasons; provide concise shift summaries to supervisors for continuous monitoring.

Secondary Functions

Assist with ad-hoc inventory research and data verification to support operations, quality, and procurement teams in resolving part number or lot traceability questions.
Participate in cross-functional projects to pilot new assembly methods, packaging designs, or process automation, providing hands-on feedback and test results.
Support maintenance teams with basic preventative maintenance checks on assembly fixtures, conveyors, and tool calibration logs and escalate any irregularities promptly.
Contribute to safety committee activities by reporting near-misses, suggesting ergonomic improvements, and participating in safety audits and toolbox talks.
Help prepare material returns to vendors (RMA) by compiling defect documentation, photos, and part samples as requested by purchasing or quality assurance.
Fill in for related roles during short staffing—such as shipping, receiving, or inventory counting—once trained, to maintain operational continuity.
Maintain and update assembly documentation, including revision control, inline checklists, and operator notes, to ensure the latest procedures are followed.
Participate in end-of-shift cleanup, recycling, and waste segregation activities to meet environmental and housekeeping goals.
Support small projects such as fixture fabrication, prototype assembly, or packing engineering trials in collaboration with engineering or product teams.
Complete required training modules (safety certifications, quality systems, ERP/WMS training) and maintain records of competency for audits and compliance.
