About Zowie:

At Zowie, we’re all about pushing boundaries in customer experience. Our AI solutions are designed to help businesses connect faster, personalize better, and solve smarter. Top online brands (True Classic, Modivo, MediaMarkt, et al.) trust Zowie’s AI agents to be on the front-line of their customer care efforts (>1.2M conversations monthly) - to give their customers rapid support, speak their brands’ voice, drive customer loyalty, and boost their revenue. With just 1 out of every 1,000 website visitors talking to customer service globally, we believe that a well thought-out AI can tap into this gap and unlock tremendous value by bringing speed and empathy to customer interactions.

We’re a team of over 100 very ambitious individuals on a mission to do just that.

What you'll do:

As the next Java engineer, you'll play a crucial role by joining one of the quickly expanding Product Engineering teams. Despite being compact, we efficiently manage and enhance a sophisticated system comprising over 100 microservices, predominantly coded in Scala and Java. These microservices communicate synchronously through gRPC, handle asynchronous calls via Kafka, expose GraphQL to the frontend, and leverage databases like PostgreSQL, Mongo, ElasticSearch, or Redis.

At Zowie, our engineering ethos is centered around the tangible impact our work has on our users. It's not just about meeting predefined requirements. It's about having a substantial influence on the overall solution. We believe in the empowerment of our engineers to contribute not only to code but also to the strategic decisions that shape our product. This requires a holistic understanding of the business, the product, and the technology at play. Your expertise will enable you to connect the dots and provide valuable insights to guide the best course of action.

Autonomy and meritocracy are at the core of our values. We champion the idea that sound arguments should prevail. As part of the team, you'll be instrumental in shaping end-to-end solutions, influencing architecture decisions, and proposing crucial enhancements to our engineering practices.

Our daily routine aligns with industry standards, including regular planning sessions, standups, timely code reviews, and close collaboration with fellow engineers.

Think of our teams as startups in a startup. We value efficiency and therefore the only constant you should expect is Retrospective. Everything else is being constantly adjusted to fit the changing needs.
