🚀 Whatnot

Whatnot is a livestream shopping platform and marketplace backed by Andreessen Horowitz, Y Combinator, and CapitalG. We’re building the future of ecommerce, bringing together community, shopping and entertainment. We are committed to our values, and as a remote-first team, we operate out of hubs within the US, Canada, UK, Ireland, and Germany today.

We’re innovating in the fast-paced world of live auctions in categories including sports, fashion, video games, and streetwear. The platform couples rigorous seller vetting with a focus on community to create a welcoming space for buyers and sellers to share their passions with others.

And, we’re growing–fast. Whatnot has been the fastest growing marketplace in the US over the past two years and has been named Glassdoor's best place to work in the small and medium business category. We’re hiring forward-thinking problem solvers across all functional areas.

💻 Role

We are looking for intellectually curious, entrepreneurial individuals to become foundational members of our Core Machine Learning team. Bringing to bear a mixture of model development and software engineering skills, you will design, develop, and deploy modes and scaled solutions to solve 0 to 1 problems across a wide variety of product surfaces. The Core Machine Learning team architects design patterns while actively contributing to initiatives spanning search, recommendation, growth, trust and safety, and fraud, to name a few. The ideal candidate is excited by the prospect of end to end execution of projects and is willing and able to wear multiple hats–no two days are exactly the same at a fast growing startup!

What you'll do:

  • Develop and deploy new production machine learning algorithms and systems that enrich the buyer and seller experience.
  • Build and help set direction across the entire machine learning development process to implement production algorithms, including exploratory data analysis, data modeling, feature engineering, model training, testing, deployment, and monitoring.
  • Contribute across the data science and machine learning development stack: ideation, opportunity sizing, prototyping, load testing, deployment, and monitoring.
  • Drive initiatives across multiple product areas and communicate findings with leadership and product teams using dashboards, notebooks, and/or documents where appropriate.
  • Design and implement end-to-end data pipelines and systems that support MLOps and critical business processes.
  • Deep dive into mission-critical problems unique to Whatnot’s livestream auction ecosystem and design bespoke algorithmic solutions.
