- Help build and maintain performance models and simulators to guide architectural decisions with data.
- Partner with the system architecture and software/modelling teams to ensure the processor delivers real-world application performance, not just benchmark wins.
- Evaluate emerging techniques — compact number formats, novel compute paradigms, advanced packaging options — to inform the architectural roadmap.
- Act as a technical mentor, raising the bar for rigour in performance analysis and architectural documentation across the team.
- Represent compute engine architecture in technical reviews, partner discussions, and customer engagements.
Skills & Experience
- Proven experience as a Processor Architect, CPU/GPU Architect, or similar role in semiconductor or high-performance computing domains.
- Deep understanding of compute engine and processor architecture and design, including matrix and vector centric floating-point arithmetic and memory hierarchies.
- Strong grasp of RTL design flows and physical design constraints and how they feed back into architectural choices.
- Experience taking processor designs from early exploration through to tapeout and post-silicon performance characterisation.
- Demonstrated ability to define and manage performance and power budgets and navigate complex trade-offs.
- Comfortable working across many disciplines, including architecture, modelling, implementation, verification, and software.
- Excellent communicator who can bridge architectural depth with system-level and product-level context.
Desirable
- Background in AI acceleration, vector/matrix compute, or domain-specific processor design.
- Experience with architectural performance modelling tools and frameworks (gem5, SystemC, custom cycle-accurate simulators).
- Familiarity with compiler and toolchain interactions, understanding how software maps to hardware.

- Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
- Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
- A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.
Preferred / Bonus:
- Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
- Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
- Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
- Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
- Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
- Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.
What we offer
- A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
- A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
