Salary: $170,000 – $290,000/yr
Type: Full-time
This role is ideal for a seasoned back-end or full-stack engineer with at least 7 years of experience who thrives in high-growth startup environments. You should have a proven track record of designing distributed systems that handle millions of users. While the team primarily uses Python, Elixir, and JavaScript, they value "language agnostic" problem solvers who prioritize product impact and user experience over specific syntax. The compensation is highly competitive, topping out at $290,000, complemented by a robust benefits package including a 4% 401k match, child care allowances, and "dogfooding" credits to shop on the platform. Although the team is "remote co-located," you must live within commuting distance of their hubs in NYC, Seattle, SF, or LA for occasional in-person collaboration. **You might be a good fit if you:** * Have navigated the complexities of payment systems, international commerce, or treasury infrastructure. * Enjoy "owning" a project from the initial architecture stage through to long-term production maintenance. * Are comfortable jumping into the frontend when necessary to push a feature across the finish line. * Want to build the financial backbone of a live-streaming marketplace experiencing massive scale.
