Senior/Staff AI Engineer

Department: Top Level - By Department

Location: Remote - California

Employment Type: FullTime

What you’ll do

• Build and optimize LLM serving and inference systems for production environments

• Improve performance across GPU and CPU pathways

• Work on KV cache, memory, storage, and throughput bottlenecks

• Design and scale systems that support RAG and retrieval-heavy AI workloads

• Contribute to infrastructure where storage architecture and systems efficiency materially affect AI performance

• Solve engineering problems at the intersection of AI, high-performance systems, and distributed infrastructure

What we’re looking for

• An engineer who has spent meaningful time building or optimizing production AI systems, not just experimenting with models

• Someone who understands how inference performance is shaped by the interaction between compute, memory, storage, and serving architecture

• Deep hands-on experience working close to the systems layer — for example, improving how workloads run across GPU and CPU resources, reducing bottlenecks, or tuning infrastructure for better throughput and latency

• Evidence of real ownership in areas like model serving, retrieval, caching, storage, or distributed performance, rather than purely application-layer AI work

• The ability to move comfortably between architecture decisions and hands-on implementation, especially in environments where efficiency and scale matter

• A background that suggests you can operate in technically demanding environments, whether that comes from AI infrastructure, high-performance systems, storage platforms, or adjacent distributed systems work

• PhD preferred, but far less important than having built serious systems in the real world

Why this role is compelling

• This is not a “prompt engineering” job.

• This is not an “AI wrapper” job.

• This is not a generic backend role with AI sprinkled on top.

• This is a chance to work on the infrastructure that determines whether modern AI systems are fast, scalable, efficient, and commercially viable.

• If you want to work on the real mechanics of AI performance — serving, retrieval, compute efficiency, memory behavior, storage architecture, and inference at scale — this is where that work happens.

Who will love this role

• Engineers who enjoy deep systems problems

• Builders who care about performance, scale, and architecture

• People who want to work where AI meets infrastructure

• Candidates who would rather solve hard technical bottlenecks than ship surface-level AI features

Who should not apply

This role is not for:

• Purely academic researchers without meaningful production ownership

• Generic software engineers without clear AI systems or inference depth

• Candidates focused mainly on prompt engineering or lightweight application integrations

• MLOps generalists who have not worked deeply on serving, storage, or performance-critical AI systems
