About the role
- Research, design, and evaluate CPU microarchitectural components (pipelines, fetch/decode, branch prediction, caches, memory hierarchy, OoO/rename/issue, interconnects, SIMD/vector/matrix units). Analyze and optimize PPA trade-offs for AI, HPC, and cloud workloads.
- Build and validate performance/functional models, run simulations, and correlate results to RTL to guide architectural decisions.
- Develop and evaluate architectural extensions within RISC-V; assess their performance, programmability, and toolchain compatibility.
- Propose, model, and prototype new mechanisms to improve efficiency, scalability, and performance.
- Work closely with hardware, compiler, and system teams to align roadmaps and enable new capabilities. Stay ahead of trends in CPU, memory, interconnect, and AI-adjacent architectures.
Requirements
- MS/PhD in CE/EE/CS (or related field) with focus on CPU architecture or microarchitecture.
- Deep expertise in CPU design (pipelines, memory systems, coherence, SIMD/vector/matrix units), PPA optimisation, and ISA extensions (RISC-V, ARM, x86).
- Skilled in performance modeling and simulation (e.g., gem5, ChampSim, Sniper, QEMU), cycle-accurate and trace-driven analysis, and correlation to RTL.
- Experienced in benchmarking and workload characterisation (SPEC, MLPerf, or internal suites).
- Proficient in RTL design and validation (Verilog/SystemVerilog/Chisel), including simulation, synthesis, and FPGA/emulation bring-up.
- Knowledge of compiler/toolchain integration, low-level software (C/C++/assembly), Linux kernel/driver development, and performance tuning for ISA features.
- Strong analytical, collaborative, and communication skills with proven ability to drive architectural proposals from concept to validation.
- Fluent in English
- Able to work from one of our European offices or remotely, preferably based in Bavaria (Munich), Belgium, or Italy.
Benefits
- pension plan
- extensive employee insurances
