Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
Describe a time you worked with manufacturing or a contract manufacturer to change a design because it was hard or expensive to build.
collaboration skill and willingness to compromise design elegance for manufacturability
Give me an example of when you had to explain a technical decision or risk analysis to someone without an engineering background.
ability to translate technical detail for non-technical audiences, since that's explicitly required
Tell me about a time you mentored a junior engineer through a technical problem. What was the situation and how did you approach it?
leadership and teaching ability, since mentoring is a stated responsibility
Technical
Walk me through a control system you designed for a generator or battery energy storage application, from requirements through to release.
whether the candidate has genuine end-to-end product development experience rather than isolated tasks
Tell me about a time you had to tune a closed loop control system that was unstable or underperforming. What did you do to diagnose and fix it?
depth of hands-on experience with control tuning and stability analysis, not just theoretical knowledge
How do you approach building a high-fidelity simulation model for a new product before hardware exists?
familiarity with model-based design and whether they can work ahead of physical prototypes
Have you used auto code generation to go from a simulation model to production code? What issues came up and how did you handle them?
real experience with the model-based design toolchain versus just knowing the concept
Describe your experience with PLC programming for machine operation. What kind of systems have you programmed and what was the outcome?
concrete PLC proficiency tied to actual equipment, since it's called out explicitly in the posting
Tell me about a validation plan you developed that used more than one test method, like HIL, bench testing, or fault injection.
whether they can design a comprehensive, layered test strategy rather than relying on one method
How have you used tools like SAP or another ERP system in managing bills of materials or part specifications?
practical familiarity with the documentation and materials systems used in production environments
Describe the most complex electrical system integration project you've worked on. What made it complex and what was your role?
scope and depth of hands-on integration experience relative to the 'moderately complex' language in the posting
Situational
Tell me about a project where the schedule, cost, and design requirements were all in tension. How did you decide what to prioritize?
judgment under competing constraints, a core part of managing product development plans
Suppose a fault injection test on a battery energy storage control system reveals a rare but serious failure mode a week before scheduled release. What do you do?
how they balance safety, risk analysis, and schedule pressure in a real product-release scenario
