About Peano AI
Peano AI is building the infrastructure and application stack for the next generation of agentic AI systems .
We believe token usage will grow exponentially over the coming years, but routing all inference through closed model providers will remain too expensive for many users and enterprises. Our thesis is that agentic applications require a vertically integrated stack: high-throughput, cost-efficient serving infrastructure paired with an application layer designed for long-running, agentic workloads.
Peano AI is building the Agent Cloud, a serving and training infrastructure platform purpose-built for agentic workloads, long-context inference, and large-scale open-source model deployment. By combining infrastructure and application design, we aim to make open-source models significantly more performant, practical, and competitive.
About This Role
We are looking for an ML Systems Engineer to help build and optimize the core serving infrastructure behind Agent Cloud. This role focuses on high-performance inference across different accelerators.
You will work on model serving performance, accelerator utilization, long-context inference, batching, scheduling, KV cache management, runtime efficiency, and cost reduction. This is a deeply technical role at the intersection of ML systems, infrastructure, and product.
Direct TPU experience is a strong plus, but not required. We care most about strong ML systems fundamentals, performance intuition, and the ability to ship reliable systems quickly.
##
What You'll Do
- Optimize large-scale LLM inference and serving systems.
- Improve total tokens per second, decode tokens per second, latency, throughput, and cost efficiency.
- Work on serving infrastructure for open-source models across different types of accelerators.
- Improve batching, scheduling, KV cache management, memory usage, and accelerator utilization.
- Support long-context inference, including workloads targeting up to 1M context.
- Debug performance bottlenecks across model execution, runtime, networking, and infrastructure.
- Work with frameworks such as JAX/XLA, PyTorch, vLLM, SGLang, TensorRT-LLM, or related systems.
- Collaborate closely with the application team to ensure infrastructure is optimized for agentic workloads, not just generic chatbot inference.
