About the Role

We are seeking an experienced systems debug engineer to investigate and resolve complex issues across applications, middleware, RTOS, firmware, drivers, and hardware platforms. This role focuses on deep root cause analysis of problems that span multiple layers of the software and hardware stack, from application failures and performance bottlenecks to silicon defects and system architecture issues. The ideal candidate is a recognized expert in debugging complex embedded systems and can rapidly isolate issues regardless of whether the root cause resides in the application, operating system, driver stack, firmware, hardware, or system architecture.

Responsibilities

Lead investigations into critical customer, field, and development issues.
Perform root cause analysis across applications, middleware, RTOS, drivers, firmware, and hardware.
Debug system crashes, hangs, lockups, watchdog resets, memory corruption, data corruption, and performance regressions.
Develop systematic debug methodologies that accelerate issue isolation and resolution.
Analyze application failures using logs, traces, profiling tools, debuggers, and instrumentation.
Debug issues involving multi-threaded, real-time, and distributed applications.
Investigate API misuse, resource leaks, synchronization errors, memory corruption, deadlocks, race conditions, and performance bottlenecks.
Correlate application behavior with operating system, driver, and hardware activity.
Partner with software teams to reproduce, isolate, and resolve customer-reported issues.
Debug scheduler, interrupt, memory management, timer, and synchronization issues.
Analyze real-time performance constraints including latency, jitter, and missed deadlines.
Investigate kernel crashes, task starvation, priority inversion, and resource contention.
Develop diagnostic tools and instrumentation to improve system visibility.
Debug issues involving processors, memory subsystems, caches, DMA engines, interrupts, and interconnects.
Utilize JTAG, trace systems, protocol analyzers, oscilloscopes, logic analyzers, and hardware debug tools.
Correlate software symptoms with underlying hardware behavior.
Work with architecture, verification, and silicon teams to identify and resolve complex hardware issues.
Profile applications and system software to identify bottlenecks.
Analyze CPU utilization, memory bandwidth, cache efficiency, interrupt load, and latency.
Drive improvements in application performance, power efficiency, and system responsiveness.
Develop automation and tooling to support large-scale performance investigations.
Serve as the escalation point for the most difficult software and hardware issues.
Mentor engineering teams on debugging techniques and root cause analysis methodologies.
Author debug guides, postmortems, and best practices.
Influence hardware and software architectures to improve observability and diagnosability.
