Whatnot is the largest live shopping platform in North America and Europe to buy, sell, and discover the things you love. Whether it's trading cards, fashion, electronics, or live plants, our sellers are building real businesses across hundreds of categories. We're building live commerce at a scale that's never been done in the West, and there's no playbook to copy. The people here are shaping how an entirely new industry develops.
As a remote co-located team, we're inspired by our values and anchored in hubs across the US, UK, Ireland, Poland, Germany, and Australia. We move fast, stay close to our users, and focus on the work that drives the most impact.
We're one of the fastest growing marketplaces and were recently named the #1 Best Startup Employer in America by Forbes. Check out the latest Whatnot updates on our news and engineering blogs and join us as we enable anyone to turn their passion into a business and bring people together through commerce.
The Seller Insights team empowers sellers to scale their businesses by delivering critical data and actionable intelligence. As we redefine live commerce, we need to equip sellers—ranging from hobbyists to high-volume entrepreneurs—with the clear, data-driven insights necessary to optimize their strategy, inventory, and sales performance.
As a Fullstack Software Engineer on the Seller Insights team, you will be pivotal in shaping the platform that translates complex data into intuitive, high-impact user experiences. You will own the end-to-end development of features that help our community thrive.
Key Responsibilities:
Architect and develop sophisticated data visualizations and UI components that turn complex analytics into clear, actionable seller strategies.
Collaborate cross-functionally with product managers and fellow engineers to identify seller pain points and translate them into scalable, high-performance features.
Navigate the full technical stack, from backend data pipelines to frontend interfaces, ensuring a seamless and performant analytics experience.
Iterate rapidly on new insights and tools, directly influencing how sellers grow their businesses on Whatnot.
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 hub.
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.
As our next fullstack engineer you should have (e.g. 4+ years of generalist software development experience in high growth startups), plus:
Bachelor’s degree in Computer Science, a related field, or equivalent practical experience.
Full-stack proficiency: You are comfortable working across the entire stack, from mobile (iOS/Android) and web to backend systems.
Strong product intuition and user empathy: You are eager to engage directly with sellers to deeply understand their needs and challenges.
Data-driven mindset: You have a solid grasp of data concepts and visualization, and can translate complex analytics into clear, actionable insights for our sellers.
Bias for action: You thrive in fast-paced environments, staying laser-focused on solving core user problems and delivering impact.
