Software Engineer, Seller Growth at whatnot

This role is ideal for a mid-tier Backend or Full-stack Engineer with at least 5 years of experience who enjoys working at the intersection of marketplace growth and platform integrity. You should be comfortable with high-scale systems and have a product-first mindset—meaning you care more about the user experience than just the technical implementation. Experience with Python, Elixir, or JavaScript is preferred, along with a background in building data pipelines or fraud prevention systems. The compensation is highly competitive, ranging from **$195,000 to $290,000**, plus a generous benefits package that includes a 4% 401k match and family planning allowances. While the role is remote-friendly, you must live within commuting distance of their Los Angeles, New York, San Francisco, or Seattle hubs for periodic in-person collaboration. **You might be a good fit if you:** * Have a track record of shipping products "lightning-fast" in high-growth environments. * Enjoy solving complex problems like identity verification (IDV) and automated risk reviews. * Can navigate ambiguous projects across the stack, from backend infrastructure to frontend features. * Want to work for a fast-growing marketplace where you’re encouraged to "dogfood" the app with a monthly budget.
