Mission

In an initial phase, design, develop, and maintain scalable and robust backend services in Java within a microservices architecture, ensuring quality, security, and performance.
In a second phase, evolve into a fullstack role, contributing to both backend and frontend development using modern technologies.

Responsibilities

Phase 1 – Backend Focus

• Design and implement backend services using Java (Spring / Spring Boot) within a microservices architecture

• Develop and maintain RESTful APIs for integration with internal and external systems

• Design, implement, and optimize relational and non-relational data models (PostgreSQL, MongoDB, SQL Server), including complex queries and basic performance tuning

Phase 2 – Fullstack Evolution

• Develop and maintain end-to-end web applications

• Build modern, responsive user interfaces using React

• Develop backend services and APIs using Node.js

Cross-Phase Responsibilities

• Create and maintain Dockerfiles and configurations for containerized services

• Follow best practices in version control, CI/CD, and deployments using Git and existing pipelines

• Implement unit and integration tests, supporting quality across SIT, UAT, and production environments

• Monitor, analyze, and resolve production incidents, ensuring system stability and observability

• Collaborate with frontend teams, core system teams (Banka), and functional analysts to translate business requirements into technical solutions

• Participate in code reviews and contribute to continuous improvement of codebase and architecture

• Document services, APIs, data flows, and architectural decisions using tools such as Jira and Confluence

Technical Requirements

Phase 1

• Strong experience in backend development with Java (Java 8+), preferably with Spring / Spring Boot

• Practical experience with microservices architectures (REST communication, event-driven systems where applicable)

• Solid understanding of REST API design (best practices, versioning, documentation)

• Knowledge of backend security (authentication, authorization, handling sensitive data)

• Nice to have: experience with messaging/event systems (Kafka, NATS, ActiveMQ), monitoring/logging, Kubernetes or container orchestration

Phase 2

• Proven experience in fullstack development

• Strong knowledge of React (hooks, state management, component lifecycle)

• Experience with Node.js (Express or similar frameworks)

• Experience working with REST APIs

• Knowledge of SQL and/or NoSQL databases

Soft Skills

• Ability to work in multidisciplinary teams and communicate effectively with both technical and functional stakeholders

• Strong problem-solving skills with a sense of ownership

• Focus on quality, performance, and maintainability (clean, testable, well-structured code)

• Openness to continuous improvement, knowledge sharing, and active participation in technical decisions

Requirements Summary

• Seniority: ~5 years of experience in software development

• Hybrid model: 2–3 days per week on-site in Lisbon
