Company

hirify.global builds hardware for frontier intelligence by co-designing custom chips, racks, software, and manufacturing systems focused on high-throughput, low-latency AI inference.

What you will do

• Define the architecture for collecting and structuring telemetry across CPUs, drivers, interconnects, and multiple accelerators.
• Design scalable models for correlating performance events across device and host boundaries.
• Align hardware counters, runtime activity, communication phases, and workload semantics across multi-device systems.
• Develop counter taxonomies, derived performance models, and instrumentation strategies for future hardware generations.
• Build tools for identifying bottlenecks in multi-accelerator workloads and distributed inference across data center networks.
• Shape developer-facing analysis engines that turn raw telemetry into actionable insight for engineers debugging large-scale AI systems.

Requirements

• Deep experience building complex systems at the intersection of hardware and software.
• Hands-on experience building profiling, tracing, observability, telemetry, or performance analysis systems.
• Strong C++ or Rust programming skills with experience shipping low-level infrastructure close to hardware or runtime systems.
• Experience correlating time-series events across distributed systems, including timestamp synchronization and trace alignment.
• Experience with high-performance computing systems, large AI clusters, hardware counters, or performance modeling for ML workloads.
• Experience leading cross-functional architectural initiatives across hardware and software teams.

Culture & Benefits

• Fully in-person work in San Jose with collaboration across engineering and research disciplines.
• Medical, dental, and vision coverage with generous premium support, plus a $500 monthly credit for waiving medical benefits.
• $2,000 monthly housing subsidy for employees living within walking distance of the office.
• Wellness benefits, daily lunch and dinner, and an unlimited compute budget subject to ROI justification.
• Significant equity and relocation support for candidates moving to San Jose.
