Senior Backend Engineer (Scala) @ Zowie

About Zowie :

At Zowie, we’re revolutionizing how businesses interact with their customers. We’re creating a future where AI Agents handle 100% of customer interactions—delivering instant, personalized, and exceptional experiences.

We believe AI Agents represent the next major technological shift, and Zowie is positioned to lead the charge. Leading consumer brands like GetYourGuide, DocMorris, Monos, Monica Vinader, Decathlon, InPost already trust our AI Agents to be on the front line of their customer care efforts, handling millions of conversations monthly.

About the role :

With great enterprises already deploying our GenAI-powered platform in many mission-critical use cases and unlocking huge wins, we’re investing in the next wave - more impact, smoother integrations, faster time-to-value. This is why we’re now growing our engineering team and hiring thoughtful Scala engineers who want to work very closely to the GenAI frontier and help build the next truly impactful product. Here, you’ll build the foundations that power our AI Agents at scale, designing systems for reliability, performance, and change.

One important thing though... We are an AI‑native engineering org . This means that you’re expected - not just allowed - to use modern AI tools in your daily work. Software engineering is changing fast with new AI tooling - and we’re not sitting on the sidelines. Here, you’ll actively push that frontier : using AI to explore designs, scaffold code, generate tests, and document decisions, while holding the line on solid engineering - clear contracts, readable code, strong test suites, observability, and maintainable architectures. This isn’t YOLO vibe-coding; it’s disciplined engineering, accelerated.

If all this sounds exciting and you're already actively using AI while coding and adapting your work style to these tools, let's talk.

Engineering @ Zowie

Despite being a compact team, 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. We believe in automatic tests, and use of Ports and Adapters practices in our services.

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. We value efficiency and therefore the only constant you should expect is Retrospective. Everything else is being constantly adjusted to fit the changing needs.

We are :

• Ambitious and innovative. We never settle. We always look for better ways of doing things.
• Like a sports team. We take ownership of our work and believe in personal accountability. At the same time, we work together, support each other, and focus on winning as a team.
• Unafraid of change. The market we're in is changing rapidly and we thrive in this ever-evolving environment.
• Growing fast. You’ll have a lot of autonomy and impact as we grow.

Ideally, you'll bring with you :

It will be awesome if you have :
