- Architect relational and non-relational data-storage strategies, including schema design and query optimization.
- Design event-driven and asynchronous flows using message brokers.
- Anticipate scalability and reliability risks and design for load, failure modes, and observability.
- Produce architecture decision records, technical specifications, diagrams, and other documentation.
- Guide and mentor development teams on best practices, code quality, and Go idioms without formally managing them.
- Communicate technical decisions and trade-offs to Product Owners, Solution Architects, engineers, and business stakeholders.
- Evaluate technologies, tools, and frameworks for the technical roadmap.
- Balance hands-on Go coding with architectural oversight.

- Experience with Kafka, RabbitMQ, or NATS and event-driven architecture.
- Strong knowledge of Docker, Kubernetes, CI/CD pipelines, and modern DevOps practices.
- Understanding of scalability, fault tolerance, security, observability, metrics, logging, and tracing.
- Experience with architecture reviews and design documentation such as ADRs and technical specifications.
- Strong communication skills for explaining architectural decisions to technical and business stakeholders.
- Readiness to work from 9:00 to 18:00 CEST.
- Readiness to complete a live Go coding task during the client interview.
- Preferred experience includes MongoDB, Cassandra, ClickHouse, Redis, AWS, GCP, Azure, DDD, SRE practices, AI/LLM production integration, open-source Go contributions, additional programming languages, and relevant cloud architecture certifications.
