Software Engineer (ML Infrastructure)
Posted Updated
- We’re hiring a Machine Learning Infrastructure Engineer to help build the backbone that trains, serves, and monitors the models behind our Ads and Recommendations products
- You’ll join a small, high-ownership team that ships platform improvements end-to-end—partnering with product and data teams, reducing latency and cost, and shortening the path from an idea to a safely launched model
- You’ll work across the ML lifecycle: making training faster and more reliable, improving model serving performance, and strengthening our feature/embedding platform so models stay fresh and consistent between offline and online use
- Design and develop machine learning infrastructure
- Own and enhance core components of the ML infrastructure, including systems for offline and online model training, model pipeline health monitoring, model serving, feature authoring, and feature serving
- Proactively address ML infrastructure issues that may impact production
- Collaborate with ML engineers to build robust model pipelines utilizing the ML infrastructure
- Scope & impact: small team, big surface area—your work lands directly in production
- Ownership: from design to rollout to post-launch learnings; real autonomy with support
- Growth: visibility across the stack and a clear path to lead projects and mentor others
- Pragmatic culture: we optimize for outcomes over buzzwords, and we value clear thinking, and follow-through
