Senior Verification Tech Lead, Graviton Team

Annapurna Labs is the team behind AWS Graviton the industrys most advanced ARM-based server SoC.
We operate like a start-up with the scale of the worlds largest cloud provider.
Were 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 development

What 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 dont 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 verification

A day in the life
As a Senior Design Verification Technical Lead on the Graviton team you will be responsible for
leading the verification of complex SoC sub-systems driving cutting-edge verification
methodologies and ensuring our next-generation Graviton server SoC meets the highest quality
bar before reaching silicon.
What Youll Do
- Develop and execute verification plans for IO sub-systems- covering interconnect
protocols peripheral interfaces and system-level integration
- Verify IO sub-system features including interconnect protocols various accelerators
engines
- 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 translation
granules 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-architectural
implementations meet performance targets alongside correctness
