Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Processor Architect - **Company:** Fractile - **Location:** Stoke Gifford, UK - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Application Performance Management, Spreadsheets, CPU Design, Systems Architecture, SystemC, Toolchain, Physical Design - **Published:** September 9, 2026 - **Apply:** https://www.collegerecruiter.com/job/2856364327-senior-processor-architect ## About the Role * 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., * 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. * Prior start-up or scale-up experience, someone who thrives in ambiguity and fast iteration. ## Description As Processor Architect, you'll define and drive the architecture of our core compute engines, ISA definitions and programming models through to memory hierarchies, and on-chip interconnects. This isn't just about hitting PPA targets on a spreadsheet; you'll work closely with logical design, physical design, and verification teams to translate architectural intent into working silicon that performs in the real world. Expect to be hands-on in performance modelling, detailed specification writing, bottleneck analysis, pre and post-silicon validation. You'll be the driving force behind the computational heart of our products ensuring every cycle counts and every watt is well spent., * Define and own the compute engine architecture specifications, balancing performance, flexibility, power, area, and design complexity. * Lead architectural exploration from early concept through to specification, coordinating with modelling, implementation, verification, and physical design teams. * Specify execution units, memory hierarchy, instruction sets and flow - making principled trade-offs at every level. * 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., * Ownership and execution: you will have full agency to drive your work forward * Rapid iteration: we all work directly with top leadership to move from idea to hardware on ambitious timelines * Full-stack engagement: hardware, software, silicon, and modelling teams all work closely together to create a product with generational impact * Optimistic and pragmatic: we possess the will to win, and to do the hard work to get us there * Team player mentality: the mission is bigger than any of us, and we have the curiosity and technical focus to see the best idea shipped, no matter whose it is ## Related Videos - [Speeding up Web Apps performance with WebAssembly and Emscripten](https://www.wearedevelopers.com/videos/1985-speeding-up-web-apps-performance-with-webassembly-and-emscripten) - [Unleashing the Full Potential of the Arm Architecture – Write Once, Deploy Anywhere](https://www.wearedevelopers.com/videos/940-unleashing-the-full-potential-of-the-arm-architecture-write-once-deploy-anywhere) - [Scoring 2000 Products per Request: Performance Pitfalls in Golang](https://www.wearedevelopers.com/videos/2073-scoring-2000-products-per-request-performance-pitfalls-in-golang) - [Building a Compiler with C#](https://www.wearedevelopers.com/videos/116-building-a-compiler-with-c) - [The Agent Interface Layer: Protocols, Tools and Trust Boundaries](https://www.wearedevelopers.com/videos/100132-the-agent-interface-layer-protocols-tools-and-trust-boundaries) - [The Power of Developer Communities](https://www.wearedevelopers.com/videos/1109-the-power-of-developer-communities) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Graph and AI Trends 2026: Why Is AI Running but Not Yet Delivering?](https://www.wearedevelopers.com/magazine/680-graph-and-ai-trends-2026-why-is-ai-running-but-not-yet-delivering) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers)
