Java Tech Lead (Alfragide - Hybrid)

We're fast learners, hard workers, natural collaborators... and we Make Modern Happen! Our ambition is to unlock the potential of our digital world so that organisations everywhere can innovate and thrive securely. We aim to achieve this goal by bringing together the world’s most talented people and the most powerful technologies, combining them to address our customers' challenges and to build something stronger together. If you share our vision, join us! Right now, we are looking for a Java Tech Lead for a client on our Talent Team. Your responsibilities include:

• Act as the technical focal point of the project.
• Maintain and evolve the solution’s cloud-native architecture, based on microservices, APIs, and event-driven patterns, ensuring cloud-agnosticism and support for Active-Active topologies, with a critical and constructive mindset.
• Ensure that developments are aligned with the defined architecture, from solution design through to production deployment.
• Perform regular code reviews, promoting engineering best practices, clean code, and automated testing as guarantees of solution quality.
• Define and manage technical debt, prioritizing critical fixes and refactors.
• Ensure non-functional quality attributes: performance, resilience, security, observability, and platform scalability.
• Support the design of high-availability (active-active) strategies, data consistency, and disaster recovery.
• Promote technical documentation (architecture, decisions, standards, development guides) and ensure its continuous update. You must have:
• Java expertise: deep knowledge of Java (recent versions) and solid experience with Spring Boot (ideally also Spring Cloud).
• Cloud-Native Architect: proven experience in designing distributed systems, microservices patterns, event-driven architectures, containers, and container orchestration.
• Strong knowledge of microservices management and patterns (circuit breaker, saga, retries, API gateway, service discovery, observability patterns, service mesh, REST, gRPC, etc.).
• Hands-on experience with event-driven architectures and messaging/streaming (Pulsar, Kafka, RabbitMQ, or similar technologies for asynchronous processing).
• Knowledge of active-active topologies, geo-distribution, fault tolerance, and high-availability design.
• Experience with distributed databases and database engines (SQL and/or NoSQL), as well as data consistency models (eventual, strong, compensation patterns).
• Solid understanding of application and API security (authentication/authorization, OAuth2/OpenID Connect, secrets management, hardening).
• Experience with continuous integration/continuous delivery (CI/CD) tools and DevOps practices. Nice to have:
• Experience in legacy-to-cloud-native system migration projects.
• Experience with observability (centralized logging, metrics, distributed tracing) and SRE.
• Previous experience in payment solutions, instant payments, or mission-critical financial systems.
• Knowledge of standards and formats in the payments domain (e.g., ISO 20022, SEPA Inst).
• Cloud and/or Cloud Architecture and/or Kubernetes certifications. We offer:
• Integration into a dynamic and motivated team for the performance of the role.
• Additional training.
• Salary package according to the role performed.

• Professional development. Workplace: Lisbon - Hybrid Claranet, Make modern happen!
