Member of Technical Staff; ML Platform Job Los Angeles area,California USA,Software Development

Position: Member of Technical Staff (ML Platform)

We’re looking for an ML infrastructure engineer to own model evaluation at Runway, end to end. Every decision we make about a model – which checkpoint to keep training, what to ship to millions of users, which datamix and architecture shows the most promise – rests on evals. Today that work is spread across the organization. You’ll turn it into one platform
Your job will be to design and build the systems that generate samples at scale, score them with automated metrics and human annotations, track results across checkpoints and releases, and put the answers in front of researchers in minutes rather than days. You’ll define what “better” means operationally – how we measure it, how confident we are, and how a result becomes a ship/no-ship decision
You’ll be embedded within research teams as a member of ML Platform, and you’ll set the technical direction for evals across the company. This is an extremely high-leverage role: the quality of our models is bounded by how well we can measure them
Our inference and training code is written in Python (PyTorch) and is cloud-native. We leverage multiple clouds and use a combination of Kubernetes native and home-grown tooling for efficient job orchestration
We’re big users of agentic development and operations. We have a robust internal platform and provide broad access to the latest models and harnesses
You’ll have access to best-in-class models, agents, GPUs, storage and cloud services you need to drive a world class evaluation pipeline that helps us deliver frontier models
Own the evaluation platform end to end: the tooling and systems required to generate, annotate, review and adapt at frontier scale
Define the CLIs, APIs, GUIs and storage layers required to make this process seamless, fast, sophisticated and collaborative
Work directly with research teams on video, image, audio, agents, and robotics to understand what they need to measure and build it, then generalize the result into the platform
Help set the standards for how we evaluate models at Runway: reproducibility, metric definitions, reporting formats, and when a result is trustworthy enough to act on
Support broad adoption of the platform and its integration throughout Runway’s research efforts across training, production model serving and more
Contribute broadly as a member of the ML Platform team to tools and systems that help Runway train and serve frontier models
