• Demonstrable experience with messaging tools such as RabbitMQ and Azure Service Bus.
• In-depth, operational maturity with the Azure ecosystem, including Azure Service Bus, Key Vault, App Registrations, and Azure DevOps.
• Experience with containerization technologies (Docker/Kubernetes) and a strong commitment to code quality, unit, integration, and automated functional testing.
• Fluent Portuguese and very good English are mandatory, along with excellent soft skills, a collaborative mindset, and a desire for continuous learning in complex environments.
• Alignment with our corporate culture and a commitment to integrity and ethics are highly valued.
• Strong customer focus, teamwork, task prioritisation, and daily commitment are highly appreciated.

What can we offer?

At Aubay, we invest in your development and well-being:

• Continuous growth through our Training Academy, with technical and soft skills training, mentoring, tech communities, workshops and in-person meetups;
• Close support with regular feedback and a structured career advancement model;
