- Develop adapters, facades, and BFF layers to support incremental migration from legacy systems.
- Optimize critical business endpoints related to key operational journeys, ensuring reliability and responsiveness.
- Define and enforce API standards, including versioning, pagination, filtering, caching strategies, and contract consistency.

- Ensure full observability through logs, metrics, distributed tracing, and monitoring of system health and latency.
- Document technical decisions, API contracts, and architectural standards to ensure governance and team alignment.
- Solid experience in backend development with Java 21.
- Strong expertise with Spring Boot for building microservices and APIs.
- Experience with event-driven architectures and Pub/Sub messaging systems.
- Background in system integration, legacy modernization, and transitional architecture design.
- Deep understanding of REST API design best practices (versioning, pagination, filtering, contracts).
- Experience with distributed systems focusing on resilience, scalability, and performance optimization.
- Knowledge of observability tools and practices (logging, metrics, tracing, monitoring).
- Ability to work in high-criticality environments with strong operational responsibility.
- Strong communication skills for technical documentation and cross-team collaboration.
- Analytical thinking, ownership mindset, and ability to propose scalable solutions.
- Remote work model with flexibility.
