As a Software Engineer on the Metal Runtime team at Tenstorrent, you’ll work on the low-level software that powers our AI accelerators
You’ll design fast, effective runtime systems that run close to the hardware, and define the host and device APIs that expose these capabilities to the rest of the software stack
We believe APIs are a core part of systems design: they encode hardware semantics, performance tradeoffs, and concurrency models, and they live longer than any single implementation
Design and evolve high-performance host and device APIs for Tenstorrent’s Metal Runtime
Develop intuitive abstractions that expose low-level hardware capabilities while maintaining performance and control
Partner closely with runtime, kernel, compiler, and software teams to build scalable, production‑ready interfaces
Contribute to runtime implementation, debugging, performance optimization, and API integration across the software stack
Drive API quality through thoughtful design, usability improvements, and long‑term maintainability
What You Will Learn:
How modern AI runtimes are designed to maximize hardware performance and scalability
How to build APIs and abstractions that balance performance, flexibility, and ease of use
How software interfaces evolve alongside next‑generation AI hardware architectures
Best practices for designing maintainable, high‑performance systems software




How to collaborate across hardware, compiler, runtime, and software teams to deliver world‑class AI infrastructure
If you enjoy pushing performance, working close to the metal, and designing abstractions that make complex systems usable without sacrificing control, this is your kind of roleWe welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this postingExperienced in designing clean, maintainable APIs and abstractions with a focus on developer experienceStrong C/C++ developer with a passion for low-level systems programming and software that runs close to hardwareComfortable working with concurrency, processors, memory movement, and performance-critical systemsThoughtful about balancing performance, usability, and long-term maintainability in systems designCollaborative, curious, and excited to solve challenging problems at the intersection of hardware and softwareDue to U.S. export laws, including those codified in the U.S. Export Administration Regulations (EAR), the Company is required to ensure compliance with these laws when transferring technology to nationals of certain countries (such as EAR Country Groups D:1, E1, and E2).
