GPU kernels engineer @ Soniox d.o.o.

Opis delovnega mesta

At Soniox, we build cutting-edge real-time AI systems, and we push every layer of the stack to its limit. As a GPU kernels engineer, you'll be at the heart of this effort: writing custom high-performance kernels that unlock the full potential of modern hardware and fuel massive-scale training and inference workloads.

You'll work across platform, research, and systems teams to accelerate our most demanding training jobs and shape model architectures around the physical realities of GPUs. If you care deeply about register pressure, tensor core utilization, warp shuffle efficiency, and squeezing every last FLOP from memory bandwidth, this role is for you.

Od kandidatov zahtevamo

In this role, you will:
- Design and implement custom GPU/CPU kernels to maximize hardware throughput and efficiency.
- Optimize for HBM utilization, instruction issue rate, cache locality, and memory bandwidth.
- Collaborate with platform and infra teams to integrate and deploy kernels at scale.
- Develop low-precision kernels and quantization-aware techniques to reduce compute without compromising ML accuracy.
- Partner with ML engineers to co-design model architectures optimized for real-time training and inference.
- Work directly with hardware vendors to advise on architecture direction and co-design opportunities.

You might thrive in this role if you:
- Write excellent C/C++ and Python code and enjoy writing fast, clean low-level systems.
- Have deep understanding of GPU (especially CUDA), CPU, or AI accelerator architectures.
- Know how to optimize every part of a compute kernel, from memory layout to instruction scheduling.
- Have experience working on large-scale ML training infrastructure, ideally for LLMs or real-time AI models.
- Are skilled in quantization and low-precision computation for modern ML workloads.
- Thrive on performance benchmarks and obsess over every percentage point of speedup.
- Have 3+ years of experience in high-performance computing, ML infra, or systems-level optimization.

O podjetju

Soniox is building the world's most advanced real-time conversational AI platform: designed to understand every conversation, in every language, anywhere. Our technology goes beyond speech-to-text: we deliver low-latency transcription, translation, and reasoning across 60+ languages, enabling businesses and developers to build next-generation products powered by voice.

We are innovating across the full stack of foundational AI for speech: from large-scale data acquisition and unsupervised dataset generation, to novel model architectures, training methodologies, and optimized inference engines. This holistic approach gives Soniox unmatched accuracy and efficiency compared to Google, OpenAI Whisper, AWS, and others.

Our API powers a wide range of applications: from live translation and meeting assistants to healthcare, call centers, enterprise productivity, and accessibility solutions.

Soniox is a fast-growing startup backed by global enterprise partners. Our engineering and product development hub is in Ljubljana, Slovenia, and we are expanding internationally. Our mission is simple but ambitious: make voice AI work for 8 billion people.
