Own the infrastructure powering AI and ML models across critical business surfaces–supporting growth, recommendations, trust and safety, fraud, seller tooling, and more.
Guide the prototyping, deployment, and productionization of novel ML architectures that directly shape user experience and marketplace dynamics.
Help design and scale inference infrastructure capable of serving large models with low latency and high throughput.
Oversee and evolve real-time feature pipelines that feed both our online and offline stores, ensuring single-second feedback from behavioral signals, high reliability, and model training fidelity.
Drive feature platform improvements and expand scope to cover non-ML use cases such as fraud rules where point-in-time backtesting is also critical.
Lead the development of distributed training and inference pipelines leveraging GPUs and both model and data parallelism.
Optimize system performance by managing resource utilization and developing intelligent feature caching strategies.
Empower scientists to iterate faster by building abstractions, APIs, and developer tools that simplify the development of near-realtime features and model iteration.
Roll out ever-better ergonomics around model training and deployment.
Stretch beyond your comfort zone to take on new technical challenges as we scale AI across Whatnot’s ecosystem.
