Senior Staff Software Engineer/Architect – Runtime Engineer
Job Description
We are seeking a Software Architect / Software Engineer with deep expertise in Linux user-space systems and AI frameworks to define and lead software architecture for next-generation inference platforms built on our Cloud AI accelerators (AI 100 and successors).
This role combines technical leadership, architecture ownership, hands-on development, enabling scalable, high-performance APIs and runtime capabilities for ML frameworks such as PyTorch.
The ideal candidate will operate across software layers—from framework integration and runtime APIs to system-level performance optimization—while mentoring engineers and driving architectural direction across teams.
Key Responsibilities
Architecture & Technical Leadership
•
Define and own the end-to-end architecture for user-space APIs and runtime layers enabling ML workloads on our AI accelerators.
•
Drive design of scalable, performant, and developer-friendly APIs for frameworks such as PyTorch.
•
Establish design patterns, best practices, and technical standards across the software stack.
•
Review and approve designs; provide technical guidance to Staff and Senior engineers.
Software Development & System Integration
•
Lead hands-on development in C/C++ and Python for custom API layers and runtime components.
•
Architect and implement multi-threaded, high-performance user-space systems.
•
Drive integration across frameworks, runtime, drivers, and hardware acceleration layers.
•
Optimize system performance including latency, throughput, and memory utilization.
Cross-Functional & Platform Leadership
•
Collaborate with hardware, firmware, compiler, and framework teams to ensure cohesive system design.
•
Influence product and platform direction through architecture decisions and performance insights.
•
Act as a technical point of contact for complex system issues and customer escalations.
Mentorship & Engineering Excellence
•
Mentor engineers across levels; elevate team capabilities through design reviews and technical coaching.
•
Drive innovation in architecture and system design, evangelizing new approaches across the organization.
Required Skills and Experience
•
12+ years of experience in software engineering with strong emphasis on system architecture and design.
•
Deep expertise in Linux user-space development and API design.
•
Strong proficiency in C/C++ (12+ years) and Python.
•
Experience designing multi-threaded and high-performance systems.
•
Solid understanding of SoC architecture (CPU, memory hierarchy, interconnects, IO subsystems).
•
Experience with source control and configuration management systems.
•
Proven ability to lead architecture across teams and influence technical direction.
•
Strong communication skills and ability to drive alignment across cross-functional stakeholders.
Preferred / Desirable Skills
•
Familiarity with CUDA, NCCL, or equivalent accelerator programming models.
•
Experience with IREE or ML compiler/runtime stacks.
•
Understanding of PyTorch 2.0 (PT2) architecture and execution model.
•
Knowledge of high-speed interfaces such as PCIe and RoCE.
•
Experience with large-scale or heterogeneous compute systems.
