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.

• Implement complex workflow orchestration using Temporal.io for business processes like asset authentication, trading, and payment processing.
• Build integrations with external services including payment processors (crypto and traditional), authentication providers, and third-party APIs.
• Create responsive mobile and web interfaces with pixel-perfect implementation and smooth user interactions for trading platforms.
• Collaborate with cross-functional teams including Product, Business Development, and Design to translate requirements into technical solutions and deliver features rapidly.
• Maintain high code quality standards through comprehensive testing, code reviews, and adherence to clean architecture principles.

• Security-first mindset for handling financial transactions, user assets, and blockchain interactions.
• Experience with workflow engines such as Temporal or similar.
• Autonomous self-starter with ability to work independently across time zones and deliver in fast-paced startup environments.
