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 had to make a technical design decision where the business wanted one thing and the long-term maintainability of the code pointed another way. What did you do?

judgment in balancing pragmatism against technical debt when they have architectural authority

Tell me about a time you mentored a less experienced engineer through a mistake in a code review. How did you handle it so they actually improved instead of getting defensive?

coaching skill and emotional intelligence, since mentoring is an explicit responsibility here

Tell me about a time a field deployment or a dealer had a problem that needed your direct technical support. What was the issue and how did you resolve it?

comfort supporting real customers and field issues, not just working in isolation on a team

Tell me about a design review or code review where you disagreed with a colleague's approach. How did the disagreement get resolved?

how they handle technical conflict and whether they can influence without just pulling rank

Technical

Walk me through a system you designed that connected an embedded device to a web or mobile application. How did you split responsibilities across the layers?

whether the candidate can architect across embedded, server, and client tiers rather than just one layer

What's your experience with Linux in production, especially around deployment and performance tuning? Give me a specific problem you solved.

depth versus surface familiarity with Linux, since it's named as a core requirement

How would you explain TCP/IP handshaking and where things commonly break down in a client-server setup, to someone newer on your team?

real networking depth combined with the ability to teach it, since mentoring is part of the job

Describe a project where you had to integrate with or develop for an embedded Linux system. What made it different from writing standard server-side software?

whether they have genuine embedded systems exposure versus purely web development background

What's an example of building a scalable API or service that later had to handle more load or more clients than originally planned? What did you change?

experience designing for scalability and extensibility rather than just meeting initial requirements

Situational

Say you're troubleshooting a remote generator monitoring system and the customer reports intermittent connection drops. Where do you start looking, and how do you narrow down whether it's the app, the OS, or the network?

structured troubleshooting across application, OS, and network layers, which the posting calls out explicitly

You're asked to estimate a chunk of work involving a new feature across C#, JavaScript, and Angular for a controller product. Walk me through how you'd break that down and what could throw your estimate off.

planning and estimation skill across a full stack, matching the stated responsibility

If a controller in the field is sending unreliable data over the network and a dealer is escalating it, but you also have a sprint deadline for a new feature, how do you decide what gets your attention first?

prioritization instincts when customer impact competes with planned delivery work
