CPU Processor Performance Verification Engineer
📌Austin, United States 🇺🇸
⏱︎ full-time
🧙♂️ senior
At IBM, work is more than a job - it's a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you've never thought possible. Are you ready to lead in this new era of technology and solve some of the world's most challenging problems? If so, lets talk.
Your Role And Responsibilities
CPU Processor Performance Verification Engineer
You will be responsible for performance validation, correlation, characterization, and tuning of IBM Z processors, with a focus on both core-level and system-level performance . This role involves pre-silicon and post-silicon performance analysis , developing targeted workloads and benchmarks, and collaborating across hardware and software teams to optimize performance across the stack.
Key Responsibilities
As a Performance Verification Engineer for IBM Z, you will:
- Collaborate with micro-architects and RTL designers to validate performance features and ensure alignment with architectural models.
- Analyze and correlate performance across pre-silicon models, RTL simulations, and post-silicon measurements.
- Develop and execute performance test plans targeting IBM Z core and system-level features.
- Design and implement assembly and C/C++ tests to stress and validate performance-critical paths.
- Build checkers and monitors to verify performance features and detect anomalies.
- Conduct coverage analysis to ensure comprehensive validation of performance features.
- Debug and tune performance issues on silicon, including pipeline bottlenecks, cache behavior, and instruction throughput.
-
Present performance findings and recommendations to cross-functional teams, including architecture, design, and software.
Master's Degree
Required Skills
Required technical and professional expertise
- 5+ years of experience in processor performance verification
- Deep understanding of IBM Z processor micro-architecture, including pipeline, cache hierarchy, branch prediction, and instruction scheduling.
- Exposure to other industry microprocessor designs (e.g. ARM, x86, RISC-V)
- Experience with performance modeling, profiling, and analysis tools.
- Strong programming skills in Assembly (z/Architecture), C/C++, Python, and scripting languages.
- Familiarity with VHDL for RTL-level validation.
- Ability to work well in a team and be productive under aggressive schedules
- Strong communication skills
Senior Embedded Software Engineer
@ Embedd 
What we're looking for
At embedd.it, we power hardware-software integration in embedded devices. We turn fragmented semiconductor chip data into configurable digital twins, then deterministically generate code, tests, and documentation – making integration faster, cheaper, and resilient to supply chain shocks.
We’re looking for a true legend – someone with abstract thinking and deep expertise in low-level software development. You’ll build vendor-agnostic tooling for MCU and peripheral integration to solve hardware-software integration once and for all. We work at the intersection of embedded systems, code generation, compilers, and machine learning. It’s your chance to help redefine how low-level development is done.
Responsibilities
- Drive the architecture of the driver structures and system layout
- Define scalable patterns for cross-architectural integration across bare-metal, Zephyr, Linux, and other environments
- Deconstruct complex SoC device trees and translate hardware descriptions into structured internal models for automated reasoning
- Partner with the ML team to shape data and annotation models for AI-driven data-extraction tooling
Qualifications
- 5+ years of experience in embedded systems development, including bare-metal and RTOS-based systems
- Proficiency in C/C++
- Familiarity with firmware configuration, SoC bring-up, and system-level debugging
- Hands-on experience with code generation tools, or low-level compiler/decompiler/emulator technologies
- Strong background in embedded toolchains: compilers, linkers, debuggers, and build systems
- Python or scripting for automation and tooling is a plus
- Experience with functional-safety standards is a plus
Why embedd.it?
- Dynamic, venture-backed team of engineers challenging the status quo 🚀
- Work at the intersection of embedded systems, code generators, compilers, and ML 🤖
- Unusual challenges requiring out-of-the-box abstract thinking 🧠
- Competitive compensation: cash + equity 💰
- Remote work possible 🌍
About Us
embedd.it is a UK-based startup reinventing embedded development. Our platform transforms unstructured semiconductor data into structured digital twins, enabling automatic generation of drivers, tests, and documentation. We're building a single, traceable source of truth to make integration fast, vendor-agnostic, and future-proof.
