Join us at Ampere and work alongside a passionate and growing team - we'd love to have you apply!
About the Role As an AI Accelerator Software Principal Engineer - Framework Integration, you will lead the design and delivery of high-performance, low-latency deep learning inference solutions. You'll help advance Ampere's AI software stack by integrating and optimizing popular deep learning frameworks so models can run efficiently across data center and edgeenvironments-meeting the performance and efficiency requirements of next-generation AI workloads.
You will operate at the intersection of software engineering, performance engineering, and hardware-aware optimization, contributing to the full stack from model execution to accelerator-ready kernel performance.
What You'll Achieve: - Framework integration for accelerator backends
Integrate and optimize deep learning frameworks-such as PyTorch, ONNX, and llama.cpp-for the Ampere deep learning accelerator backend, enabling efficient and correct execution across a wide set of model types. - End-to-end deep learning performance acceleration
Go deep into the full software/hardware execution stack, including: - inference serving and orchestration
- framework integration layers
- compiler and graph/runtime support
- runtime libraries and user-mode execution paths
- compute kernel development
- profiling, benchmarking, and performance tuning
- Model enablement with quality and speed
Improve both performance and accuracy for models using popular frameworks, and ensure compatibility with serving ecosystems such as vLLM and SGLang-helping deliver production-ready inference behavior. - Hardware/software co-design and optimization
Partner with hardware and platform teams to co-optimize AI execution for better outcomes: - increased throughput
- reduced latency
- improved scalability
- better resource utilization (compute/memory/IO)
- higher sustained performance under realistic workloads
- Build state-of-the-art AI software components
Contribute to the development of software and hardware AI co-processors/accelerators, delivering reusable libraries, optimized execution paths, and robust integration with existing tooling. - Cross-functional collaboration
Work closely with cross-functional teams (compiler/runtime, kernels, platform, and product engineering) to integrate AI capabilities into Ampere's cloud-native processor platforms and accelerators.
About You: - Education & experience : BS Computer Science, Computer Engineering, Electrical Engineering, or Software Engineering or related technical field & 8 years of related experience; or MS degree & 6 years; or PhD & 3 years
- Core framework experience: Strong experience building with or integrating AI frameworks such as PyTorch, llama.cpp, and ONNX.
- Linux + accelerator/runtime expertise (preferred): Experience with developing user-mode drivers, runtime libraries, or low-level integration for GPUs or deep learning accelerators in Linux is a plus.
- Strong systems programming & performance skills:
- Expert in Python and C/C++
- Strong background in performance profiling and tuning (latency/throughput, memory behavior, kernel efficiency)
- Deep ML understanding: Solid understanding of AI/ML concepts including neural networks and data processing frameworks. Experience with modern deep model architectures such as Transformers and Diffusion models is preferred.
- Modern AI tooling fluency (preferred): Fluent with modern AI programming tools such as Codex or Claude Code, and comfortable accelerating development workflows.
What We'll Offer: At Ampere we believe in taking care of our employees and providing a competitive total rewards package that includes base pay, cash long-term incentive, and comprehensive benefits. The full base pay range for this role is between $182,000 and $273,000, except in the San Francisco Bay Area where the range is between $195,000 and $292,000.
Our benefits include health, wellness, and financial programs that support employees through every stage of life.
Benefit highlights include:
