What an assembler does

An assembler puts together products or sub-assemblies from components, following written or visual instructions, drawings or work orders. The role converts loose parts into a finished, working item ready for the next stage or for dispatch.

It is a hands-on production role, often worked in shifts on a line or at a bench. Day to day it combines manual dexterity, steady pace and quality checks, supported by hand tools, power tools or simple jigs.

How the role is recruited

  • Roles are filled directly or through staffing agencies, often with on-the-job training.

  • Onboarding covers the products, tools, procedures and safety.

Documents involved

  • A job advert and clear job description.
  • An employment contract or agency assignment terms.
