I would design the feature architecture, implement it in accordance with coding standards, create unit and integration tests, and work with systems engineers to verify traceability and correct behavior in the target environment. What practices do you use to ensure reliability in embedded, safety-critical software? I use clear requirements traceability, defensive programming, peer reviews, static analysis, controlled configuration management, and layered testing. I also prioritize deterministic behavior, robust error handling, boundary-condition testing, and thorough documentation of design decisions. Describe your experience with C/C++, Ada, and Python in an embedded environment. C and C++ are well suited to performance-sensitive embedded implementation, while Ada can provide strong typing and reliability advantages for critical systems. Python is valuable for test automation, data analysis, tooling, and integration support; I select each language based on system constraints and verification needs. How do you handle integration issues between software and systems engineering teams? I establish clear interface definitions, assumptions, version ownership, and test responsibilities early. When an issue occurs, I reproduce it with evidence, isolate the likely boundary or requirement gap, communicate findings clearly, and coordinate a documented resolution with the relevant stakeholders. How would you manage a defect discovered late in the verification cycle? I would first assess the defect's operational impact, severity, affected configurations, and any safety implications. Then I would identify the root cause, implement and review a controlled fix, execute targeted regression testing, update traceability artifacts, and communicate status and residual risk to the program team.
