Software Engineer, AI accelerator Runtime
关于团队
OpenAI的硬件部门为先进AI工作负载的独特需求开发AI原生硅芯片和系统级解决方案。在Jalapeño等工作的基础上，该团队正在开发下一代AI原生硅芯片和紧密集成的系统，以支持前沿模型的下一次迭代。通过芯片、系统、工具和方法的协同设计，该团队帮助为OpenAI的超级计算平台交付更快、更高效且可投入生产的硬件。
关于职位
你将构建低层设备运行时，将编译后的程序转化为在OpenAI定制AI加速器上的高效、功能完整且性能优越的执行。此软件将调度内核启动，管理设备内存和地址空间，协调同步，并向更高层的运行时和框架提供可靠的抽象。
你将在软件和硬件的边界工作，与编译器、内核、架构、验证和硅芯片团队合作，定义接口并验证行为。你还将使用并改进基于事件的、周期精确的仿真，以在硅芯片可用之前开发运行时功能，诊断性能和正确性问题，并指导软硬件协同设计。
在这个职位中，你将：
- 为OpenAI定制硅芯片设计和实现低层设备运行时。
- 构建内核启动调度、命令提交、队列、依赖跟踪和完成处理。
- 管理设备内存空间、分配、虚拟到物理映射、数据移动以及跨并发工作负载的生命周期。
- 实现正确的且高效的同步原语、事件、屏障、流和排序保证。
- 定义运行时、驱动程序、固件、编译器生成代码、内核和更高层执行系统之间的清晰接口。
- 使用基于事件的、周期精确的模拟器，在硅芯片可用前后开发、验证、调试和性能调优运行时行为。
- 诊断跨越软件和硬件边界的并发性、内存排序、死锁、竞争、正确性和性能问题。
- 构建测试、追踪、分析、可观测性和可复现的工作负载，以确保运行时的正确性和性能。
- 与架构和硅芯片团队合作，将工作负载和模拟器的洞察转化为软硬件接口的改进。
如果你具备以下条件，可能会在这个职位上表现出色：
- 具有扎实的底层系统编程能力

About the Team
OpenAI’s Hardware organization develops AI-native silicon and system-level solutions for the unique demands of advanced AI workloads. Building on efforts like Jalapeño, the team is developing future generations of AI-native silicon and tightly integrated systems to power the next generation of frontier models. By co-designing chips, systems, tools, and methodologies, the team helps deliver faster, more efficient, and production-ready hardware for OpenAI’s supercomputing platform.
About the Role
You will build the low-level device runtime that turns compiled programs into efficient, functional and performant execution on OpenAI’s custom AI accelerator. This software will schedule kernel launches, manage device memory and address spaces, coordinate synchronization, and expose reliable abstractions to higher-level runtimes and frameworks.
You will work at the boundary of software and hardware, partnering with compiler, kernel, architecture, verification, and silicon teams to define interfaces and validate behavior. You will also use and improve event-based, cycle-accurate simulation to develop runtime capabilities before silicon is available, diagnose performance and correctness issues, and guide hardware-software co-design.
In this role, you will:
- Design and implement the low-level device runtime for OpenAI custom silicon.
- Build kernel-launch scheduling, command submission, queueing, dependency tracking, and completion handling.
- Manage device memory spaces, allocation, virtual-to-physical mappings, data movement, and lifetime across concurrent workloads.
- Implement synchronization primitives, events, barriers, streams, and ordering guarantees that are correct and efficient.
- Define clean interfaces between the runtime, drivers, firmware, compiler-generated code, kernels, and higher-level execution systems.
- Use event-based, cycle-accurate simulators to develop, validate, debug, and performance-tune runtime behavior before and after silicon availability.
- Diagnose concurrency, memory-ordering, deadlock, race, correctness, and performance issues across software and hardware boundaries.
- Build tests, tracing, profiling, observability, and reproducible workloads for runtime correctness and performance.
- Partner with architecture and silicon teams to turn workload and simulator insights into hardware-software interface improvements.
You might thrive in this role if you:
- Have strong low-level systems programming experience in C, C++, Rust, or comparable environments.
- Have built runtimes, drivers, firmware, operating-system components, accelerator software, or adjacent systems infrastructure.
- Understand concurrency, synchronization, asynchronous execution, queues, events, and memory-ordering semantics.
- Understand memory management, address spaces, DMA, caching, coherency, and hardware-software interfaces.
- Have hands-on experience with event-based, cycle-accurate simulators or closely related architectural and performance models.
- Can reason quantitatively about scheduling, latency, throughput, utilization, contention, and resource tradeoffs.
- Are skilled at debugging failures that span software abstractions, device interfaces, and hardware behavior.
- Work effectively across compiler, kernel, architecture, verification, firmware, and silicon teams.
