• Bring up and debug new boards.

• Analyze performance, memory, and power profiles and implement optimizations.

• Investigate field issues, perform root-cause analysis, and deliver robust fixes.

• Foster good software engineering practices.

You might thrive in this role if you:

• Have deep experience shipping embedded systems (around 10+ years).

• Are proficient in C and C++.

• Are familiar with embedded toolchains, operating systems, and debugging tools.

• Have experience with both rapid prototyping and scalable product development.
