Systems Software Engineer

Quadric is hiring a Systems Software Engineer (onsite) to build foundational systems layers that connect its GPNPU hardware with a high-level SDK.

Responsibilities

• Maintain and optimize the architecture validation and software development simulator
• Lead design of a low-level toolchain that translates code, supports binary execution (including ELF), and loads code
• Build and iterate debugging tools and backends for deep, low-level visibility into core GPNPU execution
• Design, maintain, and document clean abstraction layers and public C++ APIs for users and SDKs to interact with hardware with minimal friction
• Independently own and expand one or more systems stack components (Simulator, Loader/Assembler, Debugger, or C++ Host APIs)
• Analyze execution trade-offs using the Instruction Set Simulator to influence next-generation GPNPU hardware and software specifications
• Deliver production-ready, low-latency API abstractions and debugging utilities used by internal SDK developers and external customers

Requirements

• 5 years+ systems software experience: simulators, toolchains, debuggers, drivers, or performance-critical C++ libraries
• Strong working knowledge of modern C++ (C++17/20) and systems-level programming paradigms
• Advanced comfort with RAII, manual memory management, object lifetimes, ownership models, and memory access optimization
• Ability to identify, design, and maintain clean abstraction layers that improve readability, maintainability, and scalability
• Proactive, adaptable approach to problems arising from a brand-new processor architecture
• Demonstrated experience working at the hardware and software boundary, including one or more of:
  • Building/extending cycle-accurate or functional simulators (e.g., Gem5, QEMU, or proprietary tools)
  • Working on debugger internals such as breakpoints, memory inspection, and GDB stubs/remote protocols
  • Shipping C++ SDKs/libraries balancing “zero-cost” abstractions with intuitive user experiences
  • Writing or maintaining assemblers, linkers, or loaders with deep knowledge of binary formats (ELF) and memory layouts
  • Writing performance-critical code where every byte and cycle counts (e.g., drivers, embedded firmware)
• Low-level hardware concepts: understanding of CPU/NPU pipelines, registers, caches, and silicon-level constraints
• Experience with CUDA, OpenCL, or Vulkan plus SIMD/SIMT architectures and host-to-device memory transfers
• Experience with Linux driver development and CMake project configuration best practices
• Familiarity with Rust for systems safety and reasoning through multi-threaded logic and complex synchronization issues
• Knowledge of integrating functional programming concepts in non-garbage-collected environments

Technologies

• C++, C++17, C++20
• RAII
• ELF, ELF formats
• Gem5, QEMU
• GDB, GDB stubs
• CUDA, OpenCL, Vulkan

• Rust
• Caltrain

Benefits

• Medical, dental, and vision insurance from day one, with premiums covered at 99% for employees
• Company-paid life insurance
• Voluntary supplemental life insurance
• STD + LTD insurance
• Commuter support including parking or Caltrain reimbursement (office is within walking distance of the Caltrain station)
• FSA + HSA
• Equity with the business
• Paid parental leave
• 401(k) retirement plan
• Flexible PTO
• Winter holiday shutdown
• Catered lunch each day in the office
• Downtown Burlingame office location near shops, cafes, and local amenities
• Collaborative, low-ego culture with significant ownership and impact
• Work culture focused on innovative disruption
