Machine Learning, Platform Engineer

Together AI
San Francisco / San Francisco, San Francisco, California, United States2025-08-22

About the job

Our team focuses on enabling custom models and dedicated inference on Together. We are responsible for building a container platform, optimizing autoscaling, minimizing cold starts, achieving the best end-to-end model performance, and providing a best-in-class developer experience with great tooling. We often focus on video or audio generation across the stack: CUDA kernels, pytorch optimization, inference engines, container orchestration, queueing theory, etc. An ideal candidate will be great at profiling/optimization but know the word kubernetes, or be intimately familiar with multi-cluster scheduling and have some sense of ML bottlenecks.

Responsibilities

New hires may work on multi-cluster orchestration, portfolio optimization, predictive autoscaling, control panes, model bring-up, model optimization, APIs for managing deployments, inference worker SDKs, and CLI tools.

Analyze and improve the robustness and scalability of existing distributed systems, APIs, databases, and infrastructure

Partner with product teams to understand functional requirements and deliver solutions that meet business needs

Write clear, well-tested, and maintainable software and IaC for both new and existing systems

Conduct design and code reviews, create developer documentation, and develop testing strategies for robustness and fault tolerance

Qualifications

Minimum

5+ years of demonstrated experience in building large scale, fault tolerant, distributed systems.

Excellent understanding of low level operating systems concepts including concurrency, networking and storage, performance and scale

Expert-level programmer in one or more of Python, Golang, Rust, C++, or Haskell

Proficiency in writing and maintaining Infrastructure as Code (IaC) using tools like Terraform

Experience with Kubernetes internals or other container orchestration systems

Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related technical field, or equivalent practical experience

Preferred

Experience running serverless inference platforms, doing model bring-up on short notice, being on call, or running a cloud provider is a very big plus

Good taste and ability to thoughtfully discuss how what you’ve built has failed over time

Experience designing, analyzing and improving efficiency, scalability, and stability of various system resources

Sound judgement for when to use and when to not use LLMs for code

Writing-heavy roles or companies are a plus
