Project tasks:

• Assess and challenge the existing microservices architecture (service boundaries, APIs, data ownership)
• Identify architectural risks, bottlenecks, and anti-patterns and define improvement measures
• Review and optimize Java-based APIs with a focus on scalability, resilience, and quality
• Evaluate event-driven data flows and system integrations (latency, idempotency, reliability)
• Support and validate the decoupling of legacy Oracle/JDBC dependencies
• Create, refine, and maintain architecture documentation (e.g., Arc42, DACI)
• Act as a technical authority and sparring partner for architects and engineering teams
• Conduct code and solution reviews and provide clear technical guidance
• Advise developers and enforce best practices and quality standards

Qualifications:

• Senior Backend Engineer and/or Solution Architect with a strong architectural mindset
• Deep expertise in Java and Spring Boot within microservices environments
• Proven experience in architecture review, validation, and optimization
• Strong full-stack understanding without active day-to-day coding
• Experience in code reviews, technical leadership, and guiding engineering teams
• Solid knowledge of relational databases (Oracle, PostgreSQL)
• Experience with event-driven architectures (e.g., Kafka, outbox pattern)
• Familiarity with cloud-native environments and Kubernetes
• Strong analytical skills with the ability to challenge and improve existing solutions
• Familiarity with GIS / spatial systems is a plus
• Experience with geospatial APIs (e.g., routing, geocoding) is a plus
