Job summary

Elorian AI in Palo Alto, CA, seeks an infrastructure engineer to design, optimize, and scale systems that serve large multimodal models. You will drive faster, cheaper, and more reliable inference, enabling researchers to push model capabilities while reducing bottlenecks.

You will own infra for deployment and evaluation at scale, collaborating with researchers to enable high-performance inference across architectures, focusing on low latency, high throughput, and robust observability.

Qualifications

• 3+ years building low-latency inference serving systems for large models.
• Knowledge of quantization, batching, speculative decoding, KV cache management.
• Experience with serving frameworks such as vLLM, TensorRT-LLM, Triton, or SGLang.
• Experience with multi-GPU/multi-node model parallelism for serving (tensor or pipeline).
• Experience with autoscaling and load balancing for production ML services.
• Track record of GPU cost optimization at scale.

Responsibilities

• Build low-latency, high-throughput inference serving systems for large multimodal models.
• Design latency, throughput, and efficiency improvements (quantization, batching, speculative decoding, KV cache).
• Optimize codebase and GPU fleet to maximize FLOPs, bandwidth, and memory usage.
• Implement multi-GPU and multi-node model parallelism for serving (tensor or pipeline).
• Build autoscaling and load balancing for production ML services.
• Establish reliability, observability, and reproducibility across the inference stack.
• Collaborate with researchers to enable high-performance inference for novel architectures.

Job description

We are a well-funded, early-stage AI lab focused on building the next generation of frontier multimodal AI models. Founded by former DeepMind researchers, including Andrew Dai, who was previously a leader on Gemini. Our team currently consists of 20 world-class scientists and engineers. We recently raised $55M in seed funding from Striker Ventures, Menlo Ventures, Altimeter Capital, and NVIDIA. We are tackling some of the hardest problems in artificial intelligence, and we are growing fast.

About the Role

We're looking for an infrastructure engineer to design, optimize, and scale the systems that serve our large multimodal models. Your work will make inference faster, more cost-effective, and more reliable, so our teams can focus on advancing model capabilities rather than managing bottlenecks.

Our focus is on performant, efficient inference, both to power real-world applications and to accelerate research. This role owns the infrastructure that ensures every deployment and evaluation runs smoothly at scale for our visual foundation models.

What You Will Do

• Build low-latency, high-throughput inference serving systems for our large multimodal models
• Design and implement techniques that improve latency, throughput, and efficiency, including quantization, batching, speculative decoding, and KV cache management
• Optimize our codebase and GPU fleet to fully utilize hardware FLOPs, bandwidth, and memory
• Implement multi-GPU and multi-node model parallelism for serving (tensor or pipeline parallel)
• Build autoscaling and load balancing for production ML services
• Establish standards for reliability, observability, and reproducibility across the inference stack
• Collaborate with researchers to enable high-performance inference for novel architectures

Skills and Qualifications

• 3+ years of experience building low-latency, high-throughput inference serving systems for large models
• Strong knowledge of inference optimization techniques (quantization, batching, speculative decoding, KV cache management)
• Hands-on experience with serving frameworks such as vLLM, TensorRT-LLM, Triton, or SGLang
• Experience with multi-GPU/multi-node model parallelism for serving (tensor or pipeline parallel)
• Experience with autoscaling and load balancing for production ML services
• A track record of GPU cost optimization at scale

Preferred qualifications (strong candidates may have some, not all):

• Experience serving multimodal (vision + language) models
• Contributions to open-source ML or systems infrastructure projects (e.g., vLLM, SGLang, TensorRT-LLM, Triton)
• A bias for action and comfort working across stacks and teams in an early-stage environment

Logistics

• Location: This role is based on-site in Palo Alto, California.
• Compensation: Depending on background, skills, and experience, the expected annual base salary range for this position is $200,000 - $400,000 USD, plus equity and benefits.
• Visa sponsorship: We sponsor visas. While we can't guarantee success for every candidate or role, if you're the right fit, we're committed to working through the visa process together.
• Benefits: We offer health, dental, and vision benefits, unlimited PTO, paid parental leave, and relocation support as needed.

Elorian AI is an equal opportunity employer. We are committed to building a diverse team and inclusive environment.
