Research Engineer, Infrastructure, Inference

Job summary

Responsibilities

We’re looking for an infrastructure research engineer to design, optimize, and scale the systems that power large AI models. Your work will make inference faster, more cost-effective, more reliable, and more reproducible to enable our teams to focus on advancing model capabilities rather than…

• Work alongside researchers and engineers to bring cutting-edge AI models into production.
• Collaborate with research teams to enable high-performance inference for novel architectures.
• Design and implement new techniques, tools, and architectures that improve performance, latency, throughput, and efficiency.
• Optimize our codebase and compute fleet (e.g., GPUs) to fully utilize hardware FLOPs, bandwidth, and memory.
• Extend orchestration frameworks (e.g., Kubernetes, Ray, SLURM) for distributed inference, evaluation, and large-batch serving.

What they're looking for

• Bachelor’s degree or equivalent experience in computer science, engineering, or similar.
• Understanding of deep learning frameworks (e.g., PyTorch, JAX) and their underlying system architectures.
• Experience with inference serving systems optimized for throughput and latency (e.g., SGLang, vLLM).
• Thrive in a highly collaborative environment involving many, different cross-functional partners and subject matter experts.
• A bias for action with a mindset to take initiative to work across different stacks and different teams where you spot the opportunity to make sure something ships.
