Portugal · Contract · Mid-Senior
We are looking for a Senior Software Engineer (Java) to join a project with our client. The client has been established for over 10 years, is part of an international group, and develops its own product focused on the financial sector.

You will work on an internal product (invoicing solution), enhancing its digital capabilities and integrating it with different standards.

This role involves full-stack development with end-to-end ownership — from product design and customer needs to cloud infrastructure and production operations — in a fast-paced, agile environment.

Key Responsibilities:

  • Design and build scalable, high-performance, and maintainable software solutions.
  • Contribute to backend development, infrastructure automation (IaC), and CI/CD pipelines.
  • Ensure code quality and reliability through testing, refactoring, and continuous improvement.
  • Collaborate with stakeholders, product managers, designers, and engineers to define and deliver new features.
  • Translate business requirements into effective technical solutions.
  • Participate actively in agile planning and Scrum ceremonies.
  • Mentor and support other developers, promoting best practices and technical excellence

Requirements

  • Strong experience in Java development, using modern frameworks such as Spring Boot; familiarity with older Java frameworks is a plus.
  • Deep understanding of API design (REST, OpenAPI, GraphQL) and microservices architecture.
  • Hands-on experience with message queuing systems such as AWS SQS/SNS and GCP Pub/Sub.
  • Skilled in working with databases, including SQL (Oracle, PostgreSQL) and NoSQL solutions.
  • Experience building and maintaining CI/CD pipelines using tools like GitLab, Jenkins, and bash scripting.
  • Proficient with common development tools — Git, Maven, and IntelliJ IDEA.
  • Practical knowledge of cloud platforms (AWS, GCP), Kubernetes, and serverless architectures.
  • Strong experience with Infrastructure as Code tools such as Terraform, AWS CDK, Pulumi, Ansible, and Helm.
  • Comfortable working in Agile environments with a DevOps mindset
  • Excellent communication and collaboration skills, with fluency in English

Benefits

  • Employment Contract;
  • Health Insurance;
  • Meal Card;
  • Gym Ticket;
  • Hybrid Work (Porto - Portugal)
