General Summary
Qualcomm is leveraging its expertise in wireless and computing technologies to drive a major technological revolution in the automotive industry. Having led the way in connected car technologies for over a decade, Qualcomm is now at the forefront of advancements in Automotive Infotainment, Telematics, ADAS/Autonomous Driving, and related technologies. The Qualcomm Automotive Team is seeking a Linux Performance SME (Subject Matter Expert) to contribute to the development of next-generation automotive solutions.
Responsibilities (include but not limited to):
- Serve as the technical authority for Linux system performance on Qualcomm automotive SoC platforms (SA8797P, SA8255P, SA8775P, and next-gen platforms)
- Identify, analyze, and resolve system-level performance bottlenecks across CPU scheduling, memory subsystem, inter-cluster interconnect, DDR bandwidth, and I/O stack
- Lead performance analysis and optimization for Linux CPU scheduler (CFS, EAS), real-time scheduling, interrupt latency, and resource contention in multi-VM hypervisor environments
- Drive resolution of complex cross-domain performance issues involving CPU/GPU/DSP co-scheduling, KGSL priority configuration, and DCVS effectiveness on automotive platforms
- Define and drive performance KPIs and regression tracking for automotive Linux platforms, including SPECint, DDR bandwidth/latency, boot KPI, and STR resume latency
- Collaborate with hardware architecture teams to influence SoC design decisions based on software performance requirements (CPU prefetch strategy, inter-cluster snoop latency, DDR configuration)
- Translate customer performance pain points into actionable engineering scope and drive resolution with internal platform, kernel, and CoreTech teams
- Partner with OEM and Tier-1 customers to characterize real-world workload performance and deliver platform-level optimizations (CPU core isolation, cluster allocation, scheduler tuning)
- Conduct architecture reviews and provide technical guidance on performance-sensitive software components in virtualized automotive environments (PVM/GVM CPU allocation, hypervisor scheduling)
- Mentor engineers and contribute to internal knowledge sharing on Linux performance methodologies
- Represent Qualcomm in technical discussions with customers and internal stakeholders on performance topics
Minimum Qualifications
- Bachelor's or Master's degree in Computer Science/Engineering, Electrical Engineering, or related field
- At the BS level, a minimum of 10 years; at the MS level, 8 years; and at the PhD level, 6 years of software engineering experience
- Deep hands-on experience in Linux kernel performance analysis and optimization on ARM-based SoC platforms
- Strong proficiency in C programming and scripting languages (Python, Shell)
Preferred Qualifications
- Expert-level knowledge in 3 or more of the following areas: Linux CPU scheduler (CFS, EAS, real-time scheduling), interrupt latency and IRQ affinity optimization, multi-VM CPU resource partitioning (PVM/GVM isolation), ARM interconnect and inter-cluster snoop latency, DDR bandwidth optimization and prefetch tuning, Linux power-performance trade-offs (CPUIdle, devfreq, DCVS, thermal), GPU/DSP co-scheduling and KGSL priority management, I/O stack performance (FBE, UFS, PCIe throughput)
- Hands-on experience with Linux performance profiling tools: perf, ftrace, systrace, simpleperf — tool development experience is not required
- Experience with automotive-grade Linux platforms in hypervisor environments (Gunyah, KVM), including cross-VM performance isolation and resource contention analysis
- Familiarity with Qualcomm Snapdragon Digital Chassis platforms (SA8797P, SA8255P, SA8775P) and their CPU/memory architecture
- Experience analyzing and resolving real-world customer performance issues such as CPU overload under multi-display workloads, DDR bandwidth saturation causing frame drops, inter-cluster latency impacting latency-sensitive tasks, and real-time scheduling failures in multi-VM environments
- Knowledge of AUTOSAR or automotive middleware performance requirements
- Proven track record of driving measurable performance improvements on shipping automotive products
- Self-driven with ability to span software, hardware, system, and customer-facing roles
- Excellent English communication skills, both written and verbal
Minimum Qualifications:
- Bachelor's degree in Engineering, Information Systems, Computer Science, or related field and 6+ years of Software Engineering or related work experience.
OR
Master's degree in Engineering, Information Systems, Computer Science, or related field and 5+ years of Software Engineering or related work experience.
OR
PhD in Engineering, Information Systems, Computer Science, or related field and 4+ years of Software Engineering or related work experience.
