Diesel Mechanic Resume Sample

In your Diesel Mechanic skills list, start out right by reviewing different diesel mechanic job ads. Make a list of your skills that match the employer’s requirements. Keep the list short and targeted because hiring managers do not have all day to go over your resume.

Keep in mind that there are plenty of mechanics who are as knowledgeable as you are when it comes to fixing diesel engines. You must always find ways to distinguish yourself from others.

In our Diesel Mechanic resume example, Adam made sure he differentiated the tasks and responsibilities he did for his previous employers. This gives his skills a new dynamic which makes them more relatable and applicable to any prospective employer.

  • Education.Licensure and certifications for diesel mechanics are not mandated by federal or state laws, so one can become a mechanic without having to go thru formal education. However, if you will go over job ads majority of the employers prefer applicants who have received formal training from schools accredited by NATEF-National Automotive Technicians Education Foundation.
  • Certification.Becoming an ASE certified technician will give you a very competitive edge because it will earn you a slot in the top tier category of efficient experts. Sign up for certification programs in various areas of diesel repairs to increase your chances of getting employed and receiving higher pay. Check the site of National Institute for Automotive Service Excellence (ASE) for courses offered.
  • Mechanical Skills.Since this job is centered on engine repair you must be familiar with the engine parts, mechanism, and tools. Your ability to troubleshoot will rely on your keen understanding of how the engine works. Though employers provide on the job training, an applicant who cannot tell the difference between a wrench and a caliper will not get a callback.
  • Computer Skills.Auto repair industry is technology driven, so you must know how to use different digital diagnostic equipment and interpret data. Experience in fixing the engines’ electrical components will certainly look good on your resume. Staying updated with the latest development in technology through special courses will certainly get you ahead of the pack.
  • Interpersonal skills.Working under the hood or engine chassis most of the time doesn’t exempt you from interacting with others. You must be able to explain to the customer what needs to be fixed and how it will be done in a manner they can fully comprehend.

Your ability to relate to your coworkers is important because it shows that you can be a good addition to the company’s workforce. Good teamwork ensures timely and efficient repairs. Make sure to balance your hard and soft skills in order to make it to the interview.

Employers are able to gauge how good of a mechanic you are during the interview. Since the only access available at the onset is your resume, you must be able to provide a good visual of your abilities.

  • Install
  • Maintain
  • Record
  • Repair
  • Replace

Tune up your bullet points by quantifying your accomplishments. A simple adjustment creates a big difference in the overall impact of your statement.

For example:

Weak: Increased the number of repeat customers
Strong: Increased repeat customers by 40%

Weak: Supervises mechanics assigned to preventive maintenance and repair of heavy-duty equipment

Strong: Supervises 15 mechanics assigned to preventive maintenance and repair for 80 of heavy duty diesel equipment
