Assemblers build finished products and the parts that go into them. They use hand tools and machines to make vehicles, toys, electronic devices, and more.

Assemblers are highly technical workers with strong engineering backgrounds who receive and conceptualize designs to create a physical model of the desired product. 

This hands-on role requires workers to understand and utilize complex designs and follow specific design specifications to ensure a product is designed effectively.

What does an Assembler do?


Assemblers work in production factories and assembly lines and may have a specialized role in the manufacturing and assembly of an item such as installing fasteners or connecting wires. They maintain an in-depth knowledge of industry safety standards and regulations, allowing them to safely operate heavy machinery and use resources appropriately. Assemblers aim to be as efficient and consistent as possible when putting together a product. They troubleshoot problems with their equipment and service it to ensure it works properly.

Good assemblers are highly efficient and have complete expertise in products that they put together. They understand the engineering principles behind an item’s design and apply those concepts to producing a high-quality and durable item. Successful assemblers use critical thinking to quickly interpret schematics and identify possible misprints or issues in the quality of materials they use. 

  • Machine Operation Knowledge

    Assemblers operate design machinery and modify machinery settings as needed to meet design specifications. They must also operate power tools and other heavy machinery while following strict safety guideline.

  • Communication Skills

    Assemblers must communicate daily with all team members and supervisor through the use of shift meetings, email, log book, and other written and verbal methods.

  • Detail Oriented

    Assemblers receive, read, and understand complex design specifications. Additionally, they must perform maintenance tasks to maintain equipment in good condition.

  • Problem Solving Skills

    Assemblers will troubleshoot any issues with designs or production. They also quickly and effectively detect malfunctions with machinery and inform managers or upper-level staff of issues as they arise.

Electronic Assembler

Electronic assemblers need to know how to use soldering equipment and understand electrical engineering.


Fabricators, such as ironworkers, often assemble large pieces of metal or sheet work, and they need to be able to use welding equipment. 

Machine Operator

Machinists operate tools and mechanisms that create different parts, which are then put together by Assemblers.

Quality Control Inspector

At the end of an assembly line, quality control inspectors examine each product to ensure that it meets the guidelines laid out in company blueprints.

What does the workplace for an Assembler look like?

Most assemblers and fabricators work in manufacturing plants, and working conditions vary by plant and by industry.

Many physically difficult tasks, such as tightening massive bolts or moving heavy parts into position, have been automated or made easier through the use of power tools. Assembly work, however, may still involve long periods of standing, sitting, or working on ladders.

Most assemblers and fabricators work full time. Some assemblers and fabricators work in shifts, which may require evening, weekend, and night work.

Largest Employers of Assemblers:

  • Transportation equipment manufacturing
  • Temporary help services
  • Machinery manufacturing
  • Computer and electronic product manufacturing
  • Fabricated metal product manufacturing

How to Become an Assembler?


Assemblers require a high school diploma or equivalent (such as a G.E.D.) at a minimum. A bachelor’s degree in mechanical or electrical engineering may be preferred for some positions. As this role requires the use of different mechanical equipment, different certificates will be required for most assembler roles. Such certificates can often be obtained through specialized training schools. Assemblers may also need a security clearance to work on government contracts.

Typical Qualifications

  • Post-secondary degrees, including associate’s or bachelor’s, may be necessary or preferred
  • Additional certifications for industry-specific machinery may be necessary
  • 0-6 years of experience, depending on previous education and current skills
  • Experience working with computer-aided drafting (CAD) software
  • Ability to read and interpret drawings and designs
  • Proven knowledge and experience using drafting tools and machinery
