About Whatnot

Whatnot is a community marketplace where you can safely buy, sell, go live and build a community with other like-minded people.

We got our start offering a buying and selling experience to collectors of Funko Pops and Pokemon cards. We became the leading marketplace for those communities and have found success launching into categories like sports cards, NFTs, and vintage fashion.

In July of 2022, we raised $260 million in a Series D funding round bringing our valuation to $3.7 billion, a 2.5x increase since our $1.5 billion valuation in September of 2021.

Our mission is to enable anyone to turn their passion into a business and bring people together through commerce. We enable anyone to connect, transact and build a business in one place -- Whatnot is bringing the in-person retail experience online.

About the role
Skills: Python

🚀 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. Whatnot has been the fastest growing marketplace in the US over the past two years and we’re hiring forward-thinking problem solvers across all functional areas.

💻 Role

  • The Commerce teams work on different aspects of buying and selling on Whatnot. From our auctions and product experience to our seller experience and fulfillment processes, these teams are deeply connected with the foundations of our business and unlock tremendous growth while creating exciting new ways for our users to transact.
  • We are fullstack teams and work across a wide surface of our product to create full-featured end to end user experiences. We rely on all of our team members to have a strong product sense and to deeply understand our users in the work they do.
  • We’re looking for backend engineers with both a strong systems background and the ability to ship high quality code quickly. You should excel at making the right tradeoffs between building it fast and building it right. We’ll often prototype new ideas quickly and then need to build them for extreme scale while coordinating closely with other teams - the ideal person for this role is an expert at both of these approaches.

👋 You

Curious about who thrives at Whatnot? We’ve found that low ego, a growth mindset, and leaning into action and high impact goes a long way here.

As our next backend engineer, you should have 5+ years of full-time software engineering experience in high growth startups, plus:

  • Bachelor’s degree in Computer Science, a related field, or equivalent work experience.
  • Expert at designing and building scalable and maintainable backend systems.
  • Knowledge of multiple programming languages (we primarily use Python, Elixir, JavaScript - knowledge of these in particular not required).
  • Ability to pick up on new technologies very quickly.
  • Excellent product instincts. You first think about users rather than the best technical solution.
  • You are known for shipping products and features lightning-fast.
  • You’re an excellent problem solver and don’t need to be told exactly what to do.
  • You can mentor others and prioritize building inclusive, supportive teams.
  • Project owner - you have strong ownership instincts and can own projects from inception to production and beyond.
