Senior Kafka Engineer (Freelance)
### About Brainsquare \& this opportunity
At Brainsquare, we help organizations design, build and manage business-critical application landscapes. We focus on long-term partnerships where technology ownership, engineering expertise and operational excellence come together.
For a strategic data integration initiative within a large-scale industrial environment, we are building a new event-driven integration platform that will become the foundation for future digital transformation.
This is not a short-term implementation assignment. The goal is to create a scalable, reliable and future-proof integration capability based on Apache Kafka, enabling real-time communication between different operational systems, applications and data platforms.
We are looking for a **Senior Kafka Engineer** who can help us build the foundation, bring Kafka expertise into the team and support the transition towards long-term platform ownership.
The assignment is based in Belgium with a hybrid working model, combining remote work with regular on-site collaboration moments in the Antwerp region.
### Your role
As Senior Kafka Engineer, you will play a key role in designing, implementing and preparing a production-grade Kafka platform.
You will work together with solution architects, software engineers and operational teams to define how event streaming should be implemented, governed and maintained.
Your responsibilities include:
* Design and set up Kafka-based event streaming solutions
* Define Kafka platform standards and best practices
* Configure and optimize topics, partitions, replication, retention and consumer patterns
* Support schema governance and event contract design
* Implement Kafka Connect integrations and data flows
* Contribute to security, access control and platform hardening
* Set up monitoring, observability and operational processes
* Troubleshoot and optimize Kafka performance and reliability
* Transfer knowledge towards engineering and operations teams
You are not only implementing Kafka: you help create a sustainable platform model.
### Ideal backgrounds
This role is typically a strong match for experienced engineers who have evolved from integration, middleware, platform engineering or event-driven architecture backgrounds and who enjoy taking technical ownership.
Relevant previous roles could include:
* Kafka Platform Engineer
* Event Streaming Engineer
* Senior Integration Engineer
* Middleware Engineer
* Platform Engineer with Kafka expertise
* Hands-on Solution Architect with strong Kafka implementation experience
You will feel at home in this role if you have worked in environments where availability, scalability and operational reliability are essential, such as:
* logistics \& supply chain
* manufacturing
* industrial environments
* utilities
* telecom
* financial services
* other 24/7 enterprise environments
