The ideal candidate is a problem-solver who thrives at the frontier of markets and tokenization, with expertise in full-stack development and blockchain integration.

We are headquartered in New York City, with flexible remote work options. Candidates open to relocating to NYC are preferred.

Why Join Us

At BAXUS, we’re building the future of how wine and spirits are bought, sold, collected, valued, and traded—and we’re doing it with experience and intent. We sit at the crossroads of booze and blockchain, solving big problems for both the drinks and crypto worlds. Whether it’s bringing transparency to rare bottle trading or turning a wishlist into a live market, everything we’re building delivers real value to real people.

This is a startup—so it’s fast, intense, and full of challenges - but it’s also spirits. Which means it’s fun, fast-moving, and full of people who care deeply about the craft, the culture, the history, the stories, and the magic of making a liquid that people love.

We’ve got big ambitions and a high-performing team that moves quickly, thinks strategically, and takes pride in building products that people actually use and love. If you’re someone who thrives on ownership, enjoys being hands-on, and wants to help shape a category-defining company, you’ll fit right in.
