How to become a mechanical engineer

Once you've decided to become a mechanical engineer, it can be important to carefully research and understand the requirements for education and training. Job postings and employment websites may list the education and qualification requirements for engineers in your field. Below you can find a step-by-step guide on how to become a mechanical engineer:

1. Get a relevant bachelor's degree or similar qualification

Most mechanical engineering jobs require candidates to hold a bachelor's degree. Many engineers may choose to pursue a master's degree to increase their specialised knowledge. You can gain more opportunities and earning potential by upskilling and attaining further qualifications.

2. Gain work experience in the industry

Job experience can sometimes be more important for employability than your level of education. It may be helpful to get substantial work experience in the field as you undergo your training. If you cannot work in your field without qualification, you can seek jobs with similar skill set requirements to help prepare you and potentially impress future hiring managers.

3. Become licensed by the National Professional Engineer Register

Becoming licensed as a professional engineer can allow you to work on more projects and can increase your income. The National Professional Engineers Register requires candidates to have an engineering degree and have their competency tested by fellow engineers. A strict code of ethics that licensed engineers must abide by known as the Engineers Australia Code of Ethics also exists.

5. Applying to relevant job postings

Once you obtain the necessary qualifications and licensing requirements, it can be a good time to begin your job search. You can visit the Indeed Job Board to look for mechanical engineering roles. Before you start applying, it can be beneficial to make sure your resume is up to date.
