Job Summary

Staff Software Engineer CPU Telemetry & Performance Engineering
Markham ON (in-office)

Overview
Our Toronto-based client is building the next generation of high-performance energy-efficient computing platforms. This role sits at the intersection of silicon firmware and operating systems ideal for senior engineers who thrive in complex performance-critical environments. Youll design and optimize custom kernel-level solutions create powerful telemetry and debugging tools and collaborate with world-class teams to ensure that no performance is left untapped.

Key Responsibilities

Build and optimize custom Linux kernel drivers that integrate with low-level firmware to expose and control advanced CPU features.
Develop performance and telemetry tooling to capture analyze and visualize CPU behavior enabling deep insights into system efficiency and scalability.
Debug and profile across the siliconfirmwareOS boundary working directly with performance counters schedulers and power management subsystems.
Collaborate with leading hardware and software engineers to push the boundaries of efficiency performance and innovation in next-generation datacenter and edge platforms.
Contribute to system bring-up kernel porting and board support packages for new CPU architectures.
Leverage open-source tools and communities (perf ftrace eBPF etc.) and contribute improvements upstream.
Investigate and resolve the most challenging performance bottlenecks spanning compiler output kernel scheduling cache/memory and interconnect.
Drive performance benchmarking methodology and automation for large-scale workloads from microbenchmarks to real application scenarios.
Provide technical leadership mentoring and guidance for cross-functional teams working on hardware bring-up firmware integration and OS performance tuning.

Preferred Qualifications

Expertise in Linux kernel internals including schedulers memory management interrupts and boot flows.
Strong background in device driver development (custom drivers PCIe I/O networking storage or accelerators).
Hands-on experience with performance counters and profiling tools (perf ftrace eBPF VTune oprofile or custom frameworks).
Familiarity with power and performance management concepts such as DVFS CPU idle states clock/power domains and thermal throttling.
Ability to debug at multiple layers: firmware kernel virtualization and user space applications.
Exposure to SoC bring-up BSP development and low-level board initialization.
Proficiency in systems programming languages (C C Python assembly) with emphasis on writing performant maintainable and low-level code.
Knowledge of CPU microarchitecture concepts (pipelines caches MMU/virtual memory coherency interconnects).
Experience working with or contributing to open-source kernel communities.
Comfort navigating ambiguous performance issues using telemetry and measurement to drive root-cause analysis.
