Intern, ML Compiler (Kernel Auto-Tuning)

Samsung Semiconductor is hiring an Intern, ML Compiler (Kernel Auto-Tuning) in San Jose, CA (on-site). When: Summer 2027. Posted November 13, 2026. Applications close February 11, 2027. Checked against the employer's posting on November 14, 2026.

Please Note: To provide the best candidate experience amidst our high application volumes, each candidate is limited to 10 applications across all open jobs within a 6-month period.

Advancing the World’s Technology Together Our technology solutions power the tools you use every day--including smartphones, electric vehicles, hyperscale data centers, IoT devices, and so much more.

Here, you’ll have an opportunity to be part of a global leader whose innovative designs are pushing the boundaries of what’s possible and powering the future.

We believe innovation and growth are driven by an inclusive culture and a diverse workforce. We’re dedicated to empowering people to be their true selves.

Together, we’re building a better tomorrow for our employees, customers, partners, and communities. What You'll Learn • Project Overview: Build a cost-model-guided auto-tuning framework for PyTorch and Triton kernels on Samsung’s compute-near-memory AI accelerator, and make it placement-aware, so that each kernel is tuned for where its data lives.

You’ll connect it to torch.compile and measure the gains on LLM inference. • Skills You’ll Learn: • Performance optimisation for a cache-less, DMA-driven accelerator: search spaces, legality rules and cost models • PyTorch compiler internals (torch.

compile, FX, Inductor autotuning) and Triton kernel compilation • Benchmarking and profiling LLM inference kernels (GEMM, attention) on simulators and hardware What You’ll Do Our ML Compiler team builds the software that runs PyTorch models on Samsung’s compute-near-memory AI accelerator: a PyTorch device and compiler backend, a Triton-based kernel compiler and an LLVM back end.

We work closely with the runtime and hardware teams and with the PyTorch and Triton open-source communities. Over the summer you’ll own one piece of making ordinary PyTorch models fast on new memory-centric hardware, from research idea to merged, measured code.

Location: Daily onsite presence at our San Jose Headquarters in alignment with our Flexible Work policy Reports to: Director • Design a search space for Triton kernel configurations on the accelerator: tile sizes, launch-grid mapping, on-chip buffer budgets and load style.

• Build legality rules with our compiler engineers that prune configurations that will not compile or will not fit in on-chip memory. • Develop a kernel cost model, calibrated against our simulator and profiler, that ranks candidates so only the most promising are benchmarked.

• Build a reliable benchmarking harness and a persistent tuning cache, so that tuning cost stays practical. • Integrate the tuner with the torch.compile Inductor autotuning path and with Triton’s autotuner.

• Extend tuning to data placement: tune kernels for a given tensor layout and export tuned costs that a placement pass can use. • Measure kernel-level and end-to-end LLM inference gains, and share results in weekly syncs and a final presentation.

• Collaborate with PyTorch and Triton developers on upstream autotuning hooks, and hand off documented, tested code. • Complete other responsibilities as assigned.

What You Bring • Pursuing a Masters or PhD in Computer Science, Computer Engineering or Electrical Engineering; PhD preferred. • Must have at least 1 academic quarter/semester remaining • Strong Python and C++, with experience writing or tuning Triton kernels or working with PyTorch compiler internals (torch.

compile, FX, Inductor). • Grounding in compilers or performance engineering: IR and passes, cost models, roofline analysis and profiling. • Preferred: auto-tuning or auto-sharding experience (e.

g. TVM/Ansor, the Halide autoscheduler, Kernel Tuner, Alpa, GSPMD), or search methods such as Bayesian optimisation or ILP. • Preferred: MLIR/LLVM back ends, scratchpad or near-memory architectures, LLM inference kernels, or publications or open-source PyTorch/Triton contributions.

• You’re inclusive, adapting your style to the situation and diverse global norms of our people. • An avid learner, you approach challenges with curiosity and resilience, seeking data to help build understanding.

• You’re collaborative, building relationships, humbly offering support and openly welcoming approaches. • Innovative and creative, you proactively explore new ideas and adapt quickly to change.
