Company

hirify.global is a semiconductor startup building high-performance and energy-efficient graphics processors for immersive content creation, simulation, and consumption.

What you will do

• Define data-parallel microarchitectures that satisfy ISA constraints for next-generation GPUs.
• Lead tradeoff analysis across performance, power, area, bandwidth, latency, and scalability.
• Develop system architecture specifications, interface definitions, and microarchitecture requirements.
• Collaborate with RTL, verification, physical design, firmware, software, and systems teams throughout development.
• Build performance models, characterize workloads, identify bottlenecks, and optimize utilization and occupancy using C++, C, SystemC, or similar environments.
• Define memory hierarchy, coherency architecture, and cache structures; support validation, silicon bring-up, debugging, tuning, and post-silicon optimization.

Requirements

• 6+ years of experience in modern data-parallel microarchitecture, including workload characterization, profiling, performance modeling, out-of-order data dependency and control, and high-performance architecture design.
• Strong understanding of data-parallel microarchitectures and subsystem integration.
• Experience with one or more of CPU, GPU, or NPU architectures; NoC/interconnects; cache coherency protocols such as CHI, ACE, or CXL; high-speed interfaces; memory systems; or power, performance, and area optimization.
• Strong knowledge of RTL development and verification methodologies, architecture modeling, and performance analysis tools.
• Familiarity with firmware and software interaction in complex SoC systems.
• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, along with strong problem-solving, communication, and leadership skills.

Culture & Benefits

• First-principles approach focused on reducing barriers to content creation and consumption.
• Values include fearless experimentation, adaptability, and selfless collaboration.
• Medical, dental, and vision premiums fully covered.
• Stock options and 401(k) matching.
• Work-from-home hardware provided.
• Commitment to a diverse, inclusive, professional, and respectful workplace.
