What does a Diagnostic Engineer do?

A Diagnostic Engineer is responsible for identifying, analyzing, and resolving technical issues in mechanical, electrical, or software systems. They use diagnostic tools, data analysis, and testing procedures to pinpoint faults and improve system performance. Working across industries like automotive, aerospace, and manufacturing, they ensure reliability and efficiency by troubleshooting failures and optimizing designs. Their role often involves collaborating with design and maintenance teams to prevent future issues.

What are the key skills and qualifications needed to thrive in the Diagnostic Engineer position, and why are they important?

To excel as a Diagnostic Engineer, you need a solid background in engineering principles, analytical problem-solving abilities, and a relevant degree such as electrical, mechanical, or automotive engineering. Familiarity with diagnostic software, hardware tools like oscilloscopes, and certifications in systems diagnostics or specific manufacturer platforms are commonly required. Strong communication skills, attention to detail, and an ability to work collaboratively with cross-functional teams help you stand out in this field. These competencies ensure accurate fault analysis, effective troubleshooting, and facilitation of timely solutions for complex technical issues.

What are some common challenges faced by Diagnostic Engineers in their daily work?

Diagnostic Engineers often encounter complex and intermittent faults that can be difficult to identify and replicate, requiring methodical troubleshooting and persistence. They may work under tight deadlines, coordinating with engineers, technicians, and sometimes customers to resolve urgent issues. Adapting to new diagnostic technologies and staying current with evolving systems is also an ongoing challenge. Successfully managing these aspects develops a deep expertise in problem-solving and enhances the engineer's value within a technical team.

Your work will directly influence vehicle quality, reliability, and customer satisfaction.

What You'll Do:

  • Vehicle Diagnostics 
  • Execute complete End of Line Procedures
  • Perform root cause analysis and resolution of electrical, mechanical, and software issues discovered during end-of-line testing and bring-up.
  • Lead and support rework operations, including defining rework instructions, verifying fix effectiveness, and closing issues in tracking systems.
  • Flash software (on vehicle and on bench), execute system calibrations with UDS protocol, and validate critical vehicle functions during initial vehicle power-up.
  • Diagnose issues across all vehicle domains-powertrain, chassis, thermal, infotainment, ADAS, body, and network communication systems.
  • Collaborate cross-functionally with Manufacturing, Quality, and Engineering teams to escalate systemic issues and ensure alignment on resolution paths.
  • Use diagnostic tools, log analysis, and CAN data interpretation (CAN Trace)  to troubleshoot complex multi-system failures.
  • Create clear, concise issue reports and failure documentation to support rapid engineering triage and closure.
  • Drive implementation of short-term containment measures and contribute to long-term design and process improvements.
  • Develop, maintain, and improve end-of-line diagnostic workflows, test scripts, and validation tools.

Who You Are:

  • Bachelor's degree in Mechanical, Electrical, Automotive, or Mechatronics Engineering-or equivalent hands-on experience.
  • Ideally 5+ years of experience in vehicle diagnostics, end-of-line testing, or integration.
  • Solid understanding of vehicle architecture and systems integration (CAN, LIN, Ethernet, high-voltage systems, etc.).
  • Proficiency with diagnostic, testing and vehicle communication tools (e.g., CANalyzer, CANoe, UDS protocol, etc).
  • Experience documenting and managing rework processes and reflash procedures in a manufacturing or prototyping environment.
  • Strong troubleshooting, problem-solving, and cross-functional communication skills.
  • Ability to thrive in a dynamic, build-focused, fast-paced startup environment.
