Weāre looking for hands-on buildersāintellectually curious, deeply technical leaders eager to shape the future of AI and ML at Whatnot. Youāll lead the development and scaling of the core infrastructure that powers machine learning and self-hosted large language model applications across the company, working side by side with machine learning scientists to bring cutting-edge models powered by near-realtime features into production and unlock entirely new product experiences. This means building systems that make advanced ML dependable and fast at scaleāfrom low-latency deep learning model serving and streaming feature ingestion to distributed training and high-throughput GPU inference. This is a role that requires strong technical depthāpotential candidates should be excited about getting and staying in the weeds. You will be expected to up-level architectural discussion, provide technical feedback, and code at least a day a week.
Own the infrastructure powering AI and ML models across critical business surfacesāsupporting 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 Whatnotās ecosystem.
US Based: We offer flexibility to work from home or from one of our global office hubs, and we value in-person time for planning, problem-solving, and connection. Team members in this role must live within commuting distance of our New York, Seattle, Los Angeles, and San Francisco hubs.
Curious about who thrives at Whatnot? Weāve found that low ego, a growth mindset, and leaning into action and high impact goes a long way here.
