As the Acceleration Kernel Developer Lead at Tenstorrent, you will take on a pivotal role in guiding the optimization of low-level workloads, kernel development, and enhancing the performance of our software for machine learning applications. You will lead a team of highly skilled engineers, ensuring our software operates at peak efficiency and delivers high-quality results to our clients and users.
This role is hybrid based out of Warsaw or Gdansk, Poland.
We 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 posting.
Who You Are
- An experienced technical leader who thrives on guiding talented engineers through complex, low-level software challenges.
- A performance-obsessed optimizer with an analytical mindset for diagnosing hardware-software bottlenecks.
- A collaborative communicator who effortlessly translates machine learning requirements into highly efficient low-level code.
- A self-motivated innovator who stays at the absolute forefront of machine learning compilation and high-performance computing (HPC) trends.
What We Need
- Strong proficiency in C/C++ with a proven track record of writing high-performance low-level code.
- Hands-on experience developing and optimizing tensor compute or data movement kernels.
- Deep familiarity with performance profiling tools and debugging complex runtime environments.
- Solid understanding of machine learning frameworks, with bonus points for GPU programming (CUDA, OpenCL) or operating system internals.
What You Will Learn
- How to program and unlock the full potential of Tenstorrent's unique, networked RISC-V and AI processor architectures.
- Advanced hardware-software co-design techniques that unify machine learning compilation with custom silicon execution.
- To scale next-generation LLMs and HPC workloads across massive, highly parallel compute grids.
Tenstorrent offers a highly competitive compensation package and benefits, and we are an equal opportunity employer.
This offer of employment is contingent upon the applicant being eligible to access U.S. export-controlled technology. Due 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). These requirements apply to persons located in the U.S. and all countries outside the U.S. As the position offered will have direct and/or indirect access to information, systems, or technologies subject to these laws, the offer may be contingent upon your citizenship/permanent residency status or ability to obtain prior license approval from the U.S. Commerce Department or applicable federal agency. If employment is not possible due to U.S. export laws, any offer of employment will be rescinded.
Skills Required
- Strong C++ systems engineering experience
- Experience reasoning about concurrency, synchronization, latency hiding, and compute vs memory trade-offs
- Data-driven optimization using profiling and benchmarking
- Debugging complex runtime or kernel-level issues in large codebases
- Designing, implementing, and optimizing GPU-style kernels (matrix multiplication, attention primitives, data-movement ops)
- Ownership of performance tuning from bottleneck identification to throughput improvements
- Contribution to host-side orchestration code and parallelization strategies
- Development of micro-benchmarks, regression tests, and tooling for correctness and performance
- Close collaboration with compiler, runtime, ML, and hardware teams
- Hybrid work based out of Warsaw or Gdansk, Poland
- Eligibility to access U.S. export-controlled technology (citizenship/permanent residency or ability to obtain license approval)
