Coffee Bar Lead Barista

Lead Barista — Job Description hacco is seeking an experienced, curious, and highly motivated Lead Barista to join our opening team in Williamsburg, Brooklyn.

hacco is a new bakery café concept centered around koji — the fermentation culture at the heart of Japanese food traditions. Through coffee, beverages, bread, pastry, sandwiches, and culinary creations, we are exploring how koji can bring new depth, flavor, texture, and possibility to contemporary food.

As Lead Barista, you will play an important role in helping establish hacco’s beverage program from the beginning. Working closely with our Beverage Manager and front-of-house team, you will help build the standards, workflows, training practices, and service culture that define the daily beverage experience at hacco.

This is a hands-on leadership role. You will work behind the bar alongside the team while helping maintain high standards for espresso, milk preparation, beverage consistency, speed, cleanliness, and hospitality.

Our beverage program will also explore applications of koji and fermentation, including our koji-based barista beverage. Prior experience with koji is not required — curiosity and a willingness to learn are.

We want to create an environment where talented people can contribute ideas, experiment, continue developing their craft, and learn from people working across coffee, baking, pastry, and culinary disciplines.
