Python Inference Engineer

Job Description

What You’ll Do

• Build and improve the inference layer of the Gcore Inference platform.
• Integrate and operate inference frameworks such as vLLM, SGLang, NVIDIA Dynamo, and TensorRT-LLM.
• Bring new language and multimodal models into production.
• Improve inference latency, throughput, memory use, GPU utilization, and cost efficiency.
• Debug performance and reliability issues across model code, inference frameworks, GPU execution, networking, and Kubernetes.
• Work with platform, infrastructure, product, and customer-facing teams to turn inference improvements into reliable product features.
• Contribute improvements to open-source inference projects when appropriate.

Qualifications

What We’re Looking For

• 5+ years of experience writing reliable, well-tested production code.
• Strong Python skills and experience designing production systems.
• Hands-on experience with PyTorch and deploying machine learning models.
• Experience with Linux, Docker, and Kubernetes.
• Experience in at least one relevant area: distributed systems, GPU computing, ML runtimes, model optimization, or cluster scheduling.
• Ability to debug complex problems across software, infrastructure, and hardware.
• Strong sense of developer experience: you think about how systems are used, not just how they work.
• Genuine interest in inference engineering. You do not need direct experience with inference engines, but you should be motivated to learn.
• Good communication and collaboration skills.

Nice to Have

• Experience with vLLM, SGLang, NVIDIA Dynamo, TensorRT-LLM, or a similar inference framework.
• Experience running GPU workloads in production.
• Knowledge of inference techniques such as quantization, continuous batching, speculative decoding, prefix caching, chunked prefill, or LoRA serving.
• Experience with CUDA, Triton, TensorRT, or other GPU programming tools.
• Experience profiling and improving model latency, throughput, memory use, or GPU utilization.
• Experience with distributed inference, multi-GPU systems, scheduling, or autoscaling.
• Contributions to open-source ML, inference, or infrastructure projects.
