Software Engineer, Scale Out

Job Title

Software Engineer, Scale Out

Role Summary

Develop and optimize low-level systems software that interfaces with Tenstorrent AI hardware to deliver scalable, high-performance infrastructure for inference and training workloads. The role is on a hybrid team based in Toronto working close to hardware, runtimes, and distributed software stacks.

Work with hardware and software teams to support bring-up, testing, and deployment of production infrastructure for distributed accelerator systems.

Experience Level

Mid-level (Level - Mid-Career). The posting does not specify required years of experience; Tenstorrent is open to contributors of various seniorities.

Responsibilities

Primary responsibilities focus on building and maintaining performance-critical system software that runs close to hardware and across compute nodes.

• Design, implement, and maintain core infrastructure and low-level libraries that interface with Tenstorrent hardware.
• Develop APIs and synchronization primitives for communication across nodes in a distributed environment.
• Optimize system-level software for performance, scalability, and reliability.
• Support hardware bring-up, system testing, and deployment with cross-functional teams.
• Integrate infrastructure components with internal programming models, tools, and runtimes.
• Use profiling and tracing tools to diagnose and improve performance in multi-node systems.

Requirements

Clear must-have systems engineering skills and practical experience working near hardware and in Linux environments. Employment is contingent on export-control eligibility; candidates may need U.S. citizenship, permanent residency, or a license under U.S. export regulations.

Must-have

• Strong C or C++ systems programming experience; comfortable with low-level programming models.
• Deep understanding of memory, threading, I/O, and low-level execution behavior.
• Experience building low-level software, drivers, embedded systems, or performance-critical infrastructure.
• Proficiency with Linux systems programming and debugging/profiling tools (gdb, strace, perf, etc.).
• Ability to work closely with hardware teams during bring-up and testing.

Nice-to-have

• Experience with distributed systems, inter-node communication, and synchronization at scale.
• Background in performance tuning across software, runtime, and hardware layers.
• Familiarity with accelerator architectures or RISC-V-based systems.

Education Requirements

Not specified.
