Fullstack Engineer, Customer Experience at whatnot

This role is ideal for a Senior-level Fullstack Engineer with at least 5 years of experience, particularly within high-growth startup environments. You should be comfortable navigating both the frontend (Next.js) and backend (Python/Postgres) to build scalable internal tools and customer-facing features that handle thousands of transactions per hour. The position offers a competitive salary range of $170k – $190k and a robust benefits package, including a 4% 401k match and generous allowances for wellness, childcare, and "dogfooding" the app. While the company is remote-friendly, this specific role requires you to live within commuting distance of their hubs in SF, LA, NYC, or Seattle for in-person collaboration. **You might be a good fit if you...** * Have a track record of shipping high-quality products "lightning-fast" in ambiguous environments. * Proficiency in Next.js for web or native mobile development. * Enjoy "owning" a product end-to-end, from initial discovery to production monitoring. * Want to work on complex logistics, purchasing, and automation challenges for a massive live marketplace.
