Role
Who you are
- As our next Fullstack Engineer you should have 5+ years of generalist software development plus:
- Bachelor’s degree in Computer Science, a related field, or equivalent work experience
- Full-stack proficiency: You are comfortable working across the entire stack, from mobile (iOS/Android) and web to backend systems
- Web development experience with React, using GraphQL for API development, and modern frontend applications (exposure to Next.js framework is not required but preferred)
- Backend Expertise: Proven track record of building end-to-end high-scale product experiences as a full-stack engineer. Experience with Python on backend, and/or Postgres databases is a plus
- Excellent product instincts- you first think about users rather than the best technical solution
- You can mentor others, and prioritize building inclusive, supportive teams
- Project owner- you’ve strong ownership instincts and can own projects from inception to production and beyond
- You are known for shipping products and features lightning-fast
- You’re an excellent problem solver and can operate autonomously
- Ability to pick up on new technologies very quickly
- Proven track record of delivering features
What the job involves
- Ads at Whatnot are both a growth lever for sellers and a revenue lever for Whatnot; When ads work, they earn seller trust by delivering real, incremental value - new buyers, new-to-category reach, and viewership that compounds
- The team owns the end-to-end ads system: backend foundations, retrieval and ranking, UI and dashboards, logging, measurement, and more
- The team is small- we expect engineers to be ready to own and lead major pieces of functionality independently
- We work closely across the rest of the engineering org, including Discovery, Seller Growth, Data Platform, Machine Learning Platform, and Payments
- We're hiring across the full ads stack — from engineers who go deep on backend systems and data to engineers who move fluidly across the stack into client and seller-facing surfaces
- In either case, you'll own problems end to end and grow into new areas as the team scales
- People who do well at Whatnot tend to be comfortable figuring things out as they go, biased toward action, and genuinely curious about what they're building
- They care more about outcomes than credit and stay close to the product and the people using it
Our take
Live shopping is changing the way people engage with eCommerce and Whatnot is one of the key platforms driving this shift. The company operates across the US, UK, and Europe, where millions of people connect each day to buy, sell, and build communities around shared interests.
Founded in 2019, Whatnot allows real-time auctions where buyers can watch sellers showcase products and share their expertise, creating a more interactive and personal shopper experience. Sellers include individual creators and small businesses who use live shows to reach audiences and grow their online presence.
As of 2025, the company reports over $6B in sales, with sellers earning significantly more on average than other major marketplaces. And with a range of investor support, Whatnot is committed to developing new ways to make online shopping more social and community-driven.
