About the position:
Can you imagine helping teams prevent breaking changes across microservices through automated contract testing?

At ERNI, you are never just a number. Even if you work on an external project, you will feel part of the team and always supported.

How do we make this happen?

With people. Besides your team and manager, you will have several support figures like a godparent, who will help you with the practical and administrative aspects of daily life during your first 6 months.

And the second most important person after you, your mentor, who will guide you through your entire onboarding and career at ERNI. You will have regular 1:1 meetings with them, and recurrently, you will work on your development plan to define your short-, medium-, and long-term goals.

At ERNI, we highly value experience and technical knowledge. As a senior profile, you will have the space to continue growing, whether by deepening your technical skills or having greater influence on project decisions, with autonomy and the opportunity to share knowledge with other experts.




- And if you are interested in mentoring, there is also space for that: supporting other ERNIans while still focusing on the technical excellence that sets us apart.

What you will bring
- Strong experience with contract testing frameworks such as Pact or similar solutions.
- Proficiency implementing CI/CD pipelines with GitHub Actions and automated testing processes.
- Solid experience working with at least two technology stacks among Node.js and Java Spring Boot.
- Strong understanding of microservices architecture, service integration and mock server implementations.
- Ability to work autonomously while producing high quality technical documentation.

You will be responsible for design and implement a contract testing framework architecture together with the Tech Lead, integrating Pact Broker, consumer and provider testing, automated validation and CI/CD workflows. You will establish regression testing
