Responsibilities

• Lead embedded firmware development, debug and fixes for silicon/SOC issues.
• Own complex investigations into firmware crashes, boot/reset failures, hangs, memory corruption, and hardware/software interaction issues across MAIA and Cobalt.
• Correlate firmware logs, silicon error records, crash dumps, OS/driver traces, configuration, and fleet telemetry to isolate failure mechanisms.
• Develop reproducible experiments and targeted diagnostic firmware or tooling to test hypotheses and distinguish firmware defects from silicon, hardware, or software causes.
• Build scalable analysis and triage automation, including failure bucketing, signature detection, cohort comparisons, and regression detection.
• Apply statistical analysis and AI-assisted methods to prioritize investigations and reduce manual analysis, validating results against independent evidence.
• Drive mitigations and permanent fixes with component owners; verify effectiveness through regression testing and post-deployment telemetry.
• Convert investigation findings into improved instrumentation, test coverage, troubleshooting guidance, and mentoring

• 8+ years of professional experience in embedded-system design, development, integration, validation, or system-level debugging.
• Experience with cross-layer root-cause analysis of firmware, silicon, or system failures using logs, crash dumps, or telemetry.
• Experience reading and debugging C/C++ firmware, together with scripting experience for automation or engineering-data analysis.
• Experience with system-level debug and validation of complex embedded systems, including boards, FPGA, emulation, or simulation environments.
• Experience managing production or fleet issues through mitigation, root cause, corrective action, and post-deployment verification.
• Experience with PCIe, memory subsystems, I2C, SPI, or other low-level platform interfaces.
• Experience with silicon bring-up, firmware initialization, and lab or source-level debug tools such as JTAG, GDB, oscilloscopes, or logic analyzers.
• Experience building automated diagnostic, test, or CI/CD pipelines and regression coverage.
• Experience using Python, KQL/SQL or equivalent tools, and statistical methods for telemetry analysis, failure-signature grouping, or cohort comparisons.
• Experience evaluating or applying AI-assisted tools to log/crash analysis, anomaly detection, or evidence-backed triage.
• Experience mentoring engineers, documenting troubleshooting methods, and collaborating across firmware, silicon, hardware, OS, and fleet teams.
