Senior Verification Tech Lead, Graviton Team

Annapurna Labs is the team behind AWS Graviton the industry's most advanced ARM-based server SoC. We operate like a start-up with the scale of the world's largest cloud provider.We're looking for a Senior Design Verification Technical Lead- a design verification technical lead that is responsible for complex SoC sub-system, with cutting edge technology for Graviton server SoC.• It starts at product definition- we engage from day one, shaping requirements and translating product intent into verification strategies before a single line of RTL is written• It extends into software- we work side-by-side with SW teams, verifying hardware-software interfaces and ensuring seamless integration across the stack• It reaches into physical design- we verify physical design aspects within functional verification, bridging the gap between logical correctness and silicon reality• It closes the loop- from spec to silicon, our verification touches every team and every stage of chip developmentWhat Sets Us Apart- Agentic AI is embedded in our workflow- not as an experiment, but as a core part of how we design and verify chips - Cutting edge methodologies drive every stage of our verification process- Relentless innovation- we don't settle; we actively seek new approaches that raise the bar on silicon quality- We do classic functional verification (SV/UVM/TLM), but beyond that, we touch physical design aspects, to ensure that the quality of our silicon is beyond logical functionality- Performance optimization at all levels is at the heart of our targets on top of logical correctness verificationA day in the lifeAs a Senior Design Verification Technical Lead on the Graviton team, you will be responsible forleading the verification of complex SoC sub-systems, driving cutting-edge verificationmethodologies, and ensuring our next-generation Graviton server SoC meets the highest qualitybar before reaching silicon.What You'll Do- Develop and execute verification plans for IO sub-systems- covering interconnectprotocols, peripheral interfaces, and system-level integration- Verify IO sub-system features including interconnect protocols, various acceleratorsengines- C embedded SW programing and SW debug skills- Build and maintain UVM-based verification environments for IO sub-systems- Verify ARM advanced interconnect protocols (AMBA CHI/ACE/AXI) ensuring correct coherency transactions, performance verification, and protocol compliance- Verify the IO virtualization SMMU/TLB operations, page table walks, translationgranules, and memory attributes (cache-ability, share-ability)- Develop constrained-random and directed test strategies targeting corner cases in IO protocol hazards, coherency races, and system boundary conditions- Drive coverage closure using functional coverage models, assertion-based verification,and formal methods where applicable- Contribute to performance verification — ensuring micro-architecturalimplementations meet performance targets alongside correctnessAbout the teamDiverse ExperiencesAmazon values diverse experiences.
