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
Tell me about a time you led a design review, like a PDR or CDR, that didn't go smoothly. What happened and how did you get the program back on track?
ability to lead technical readiness reviews and handle pushback from customers or peers under program pressure
Describe an actuator or mechanical system failure you root-caused, either in test or in the field. How did you trace it back to the source?
depth of hands-on failure analysis experience and rigor of their problem-solving method
Tell me about a time you had to balance performance, weight, cost, and manufacturability on a design and something had to give. What did you choose and why?
real tradeoff decision-making experience versus reciting textbook design principles
Tell me about a time you gave technical oversight to a supplier who was struggling with quality or producibility. How did you handle it?
ability to influence outside their own organization and apply DFM/DFA judgment in a real supplier relationship
Describe a continuous improvement or lean initiative you drove, either in your own engineering group or at a supplier's facility.
genuine ownership of continuous improvement work versus passive participation
Tell me about a time a customer pushed back hard on a design decision. How did you handle the conversation?
customer-facing technical communication skill and composure under scrutiny
Technical
Walk me through how you'd approach sizing a motor and gear train for a new flight-critical actuator, starting from a torque-speed requirement.
whether the candidate has real hands-on system architecture and sizing experience versus just component-level knowledge
How do you go about flowing down system-level requirements to individual actuator components like the gearing, ball screw, or housing?
understanding of requirements management and systems thinking, not just detailed component design
What's your experience with GD&T on flight-critical hardware, and can you describe a tolerance stack-up problem you had to solve?
depth of practical GD&T fluency required for actuator drawings, not just familiarity with the concept
How familiar are you with PPAP and APQP, and can you describe a time you used those tools on a new part introduction?
whether their process knowledge is real working experience or just resume language
What manufacturing processes have you worked with directly, like metal cutting or grinding, and how has that shop-floor exposure changed how you design parts?
whether their design decisions are grounded in real manufacturing constraints, per the stated metal manufacturing background requirement
Situational
Say you find a position sensor is drifting out of spec during life testing, but you're two weeks from a customer milestone. Walk me through what you'd do.
how they balance technical rigor against program schedule pressure and whether they'd cut corners
A key supplier tells you a long-lead gear component is going to be six weeks late, threatening your build schedule. What do you do?
how they manage supplier risk and adapt program plans under material constraints, a stated job requirement
You're managing several new product introductions at once and two hit critical milestones the same week. How do you decide where your attention goes?
time and program management skills across competing priorities, which the posting explicitly calls out
