Job description

Company: Qualcomm Technologies, Inc. Job Area: Engineering Group, Engineering Group > CPU Engineering General Summary: About the Role We are building a high-performance, production-grade RISC-V Instruction Set Simulator (ISS) that serves as the golden reference model for a family of next-generation 64-bit RISC-V processors. The ISS is a key component of our verification flow: it drives co-simulation against RTL, powers random test generation, and gives software teams a fast, accurate platform to develop and debug pre-silicon firmware. The work is at the intersection of computer architecture, systems software, and verification engineering — writing the kind of C++ that has to be both correct to the bit and fast enough to run long-running benchmarks and boot Linux. What You'll Work On • Implementing the ISA: Translate RISC-V specification chapters into working C++ code. We cover a wide range of extensions: integer, floating-point, vector, bit manipulation, security features, interrupt handling, and more. • Simulation correctness: Help maintain the fetch/decode/execute engine, memory protection, virtual memory, and privilege-level logic that make the simulator a trustworthy reference. • Co-simulation: Work on the harness that runs the ISS alongside RTL and flags any differences, one instruction at a time. • Testing: Write targeted unit tests that exercise individual features and compare against expected results derived from the RISC-V spec. • Developer tooling: Contribute to and maintain a large collection of simulator extensions and utilities that help the user community be more productive. What We're Looking For • Solid C++ skills and comfort reading unfamiliar codebases. • Comfortable with basic processor architecture, including pipelines, memory, privilege levels, and interrupts. • Strong attention to detail; this work is spec-driven and correctness matters. • Willingness to read a specification document and turn it into tested code. • Some exposure to low-level or systems programming, such as embedded systems, operating systems, compilers, or hardware description. Nice to Have • Experience with RISC-V, x86, or ARM architecture. • Familiarity with simulators or emulators such as QEMU, Spike, gem5, or similar tools. • Experience with GDB, ELF binaries, or bare-metal bring-up. • Background in hardware verification or RTL co-simulation. • Knowledge of Linux internals. • Python 3+ experience. Minimum Qualifications: • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field and 4+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience. OR Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or related field and 3+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience. OR PhD in Electrical Engineering, Computer Engineering, Computer Science, or related field and 2+ years of Hardware Engineering, Software Engineering, Electrical Engineering, Systems Engineering, or related work experience.
