Technical Detailing Standards

We evaluate your ability to produce high-quality results consistently. Strong candidates demonstrate a systematic approach to cleaning, showing they understand the "why" behind the products and tools they use.

• Chemical Safety – Understanding the pH balance of cleaners and their effects on different surfaces.

As a Mobile Engineer, your primary responsibility is the delivery of professional-grade car detailing services at the customer's location. This involves much more than cleaning; it is a full-service experience. You will be responsible for setting up your mobile station, performing the detail according to SHWASH protocols, and conducting a final quality check with the customer.

Collaboration is key, as you will interact with the central dispatch team to coordinate your daily route and provide updates on job status. You are expected to proactively manage your own equipment—ensuring your vehicle is clean, your tools are in working order, and your supplies are replenished. Your success is measured by the quality of the finish on the vehicle and the satisfaction of the customer.

To be a competitive candidate for the Mobile Engineer position, you must possess a strong foundation in automotive care and the necessary resources to perform the job.

• Must-have requirements:

  • Own vehicle capable of transporting professional detailing equipment.
  • Own professional-grade detailing tools and supplies.
  • Proven track record in automotive detailing or related service industries.
  • Valid driver’s license and a clean driving record.
  • Ability to manage a mobile work environment independently.

• Nice-to-have qualifications:

  • Experience with high-end or luxury vehicle detailing.
  • Certification from recognized detailing organizations.
  • Advanced knowledge of paint correction and ceramic coating application.

Q: Is there a practical test during the interview? A: Depending on the location, you may be asked to demonstrate your knowledge of specific detailing techniques or equipment usage. Be prepared to talk through your process in detail.

Q: What is the most important trait you look for? A: Reliability. We need to know that you are organized, punctual, and capable of maintaining the high standards of SHWASH while working independently in the field.

• Show Your Work: If you have a portfolio of your detailing work, bring it. Visual evidence of your attention to detail is highly persuasive.
• Know Your Kit: Be prepared to explain exactly why you use the specific products you do. We value technicians who think critically about their results.
• Be Punctual: Your interview is a test of your ability to arrive on time for a client. Treat the interview as if it were your first service appointment.
• Communication is Key: Clear communication with the customer is a major part of the role. Practice explaining your process in a way that is easy for a non-expert to understand.

The Mobile Engineer role at SHWASH is a fantastic opportunity for detailers who take pride in their craft and want to operate with independence.
