Senior Engineer - Testing - Microservices

Can you imagine helping teams prevent breaking changes across microservices through automated contract testing?

Join our expert team to work on a modern software quality initiative, contributing to the implementation of a contract testing framework for microservices integration. You will apply your knowledge of Pact
, Git Hub Actions
, CI/CD practices and automated testing to ensure service compatibility, contract validation and reliable deployments across multiple technology stacks.

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.

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  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.

• Strong experience with contract testing frameworks such as Pact or similar solutions.
• Proficiency implementing CI/CD pipelines with Git Hub 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 strategies, implement pull request quality gates, support multiple technology stacks and create onboarding documentation to ensure framework adoption across development teams.

We work on a wide variety of projects, technologies, and sectors, allowing you to keep growing in different environments. If a project ends or you feel ready for a new challenge, we will find another one that aligns with your professional development.

We ask you to be available for key meetings. Need to leave for a doctor’s appointment or to pick up your child from school? No problem. We trust you to deliver quality work within your 40-hour workweek.

Our model is hybrid: we usually go to the office 2 days a week, though this depends on the project and team, but we love seeing each other’s faces; the best stories always happen in the office!

• Hybrid working schedule.
• Supportive onboarding and mentoring.
• Opportunities to work with diverse projects and technologies.
• Autonomous working environment and technical influence.
• Focus on technical excellence and knowledge sharing.

We will discuss it during the first call. If it is important to you, feel free to ask!
