Senior Backend Engineer (Product)

At Exacaster we impact the lives of over 40 million consumers on a daily basis by working with clients in the Baltics, USA, Central and South America and the Caribbean. We operate one of the largest big-data environments in the Baltics, and we run some of the most challenging analytical workloads on top of one of the most diverse customer-data sets you’ll find anywhere. Exacaster’s team is looking for a Senior Backend Engineer to join our CVM Platform team.

About the role

You would be joining our Product team (Kittyhawk) as a Senior Backend Engineer. Our CVM Platform helps telcos grow customer value through next best offer recommendations, churn prediction and omnichannel campaigns. It is becoming an agentic platform, and we build it the same way: our engineers spend less time typing code and more time specifying, steering and checking the work of coding agents.

This is not a slide-deck ambition. We built Automaton, our in-house software factory. Give it a ticket and it sets up its own environment, mocks the dependencies, writes and runs the tests, and returns a merge request with a report. It is already connected to our product analytics, so a problem spotted in production becomes a ticket and a merge request in a few clicks. You’ll help make the factory itself better.

• The platform runs on Kubernetes, in the cloud for some clients and on-premise for others. It is a set of microservices: Java and Python services behind REST APIs, Kafka, Spark jobs, PostgreSQL, MongoDB and a React frontend.

Who should apply

You’re a backend engineer at heart: the JVM, distributed systems, data at volume. And you think in software factories: agents write, test and review, while you set the spec, the guard-rails and the quality bar. Maybe you already run one. Maybe you’re still figuring out how, and can’t stop trying. Either way, you’d rather build the machine that ships the feature than ship it by hand.

• Depth is where you start, not a wall you stay behind: if a feature needs a frontend change, you and your agents make it.

This role is probably not for you if

• You see AI coding tools as mostly hype, or you’d rather write every line yourself. We respect that craft, but this team is built on the opposite bet.
• You prefer tasks that come with the technical approach and step-by-step instructions already set. Here you shape the solution yourself.

How we hire

• Conversations, not exams. There is no take-home assignment and no live-coding test. We’ll ask you to walk us through something you built.
