Senior Full Stack Developer

We are looking for a 10x, next-level full stack developer to build Python/FastAPI services and React interfaces on a fast-paced team — AI-led, spec-driven development. Registix operates in reverse logistics and liquidation, helping move returned and excess inventory back into the market. We are building technology that connects inventory, purchasing, sales, and operations, making complex workflows easier for our teams and customers. This is not a maintenance job. We are looking for a 10x developer — someone genuinely next level, who ships more in a week than most teams ship in a month, and who wants to keep leveling up. If you are looking to accelerate your career, take real ownership, and see your work in production fast, this is the seat. We are looking for a product-minded full stack developer who can take a business problem from an initial conversation to a reliable, usable product. You will build across Python/FastAPI services and React interfaces, working closely with technology leadership and business teams to shape what we build and how it works. The pace here is fast and the bar is high. You should be comfortable working from high-level direction and incomplete requirements: asking thoughtful questions, making practical recommendations, and creating clear specifications before implementation. We embrace AI-led development and expect you to use AI coding tools and agents aggressively while owning the quality of everything you ship. Base pay range is $140,000–$185,000, plus a bonus based on revenue targets and achievement. Along with your resume, share an example of a product or feature you helped take from idea to production. Tell us what you owned, how you clarified the requirements, and how you use specifications and AI tools in your development process.
