Do you want to work for an International Service Delivery Center in Spain as a

Senior

React Developer ?

You will be part of a cross-functional agile team building a next-generation data management platform within a highly regulated environment. The system is designed using a distributed, event-driven microservices architecture, handling complex workflows, real-time data processing, and integrations with external systems.

The platform emphasizes scalability, resilience, traceability, and high reliability, leveraging modern technologies such as Rust, container orchestration, and event sourcing patterns. The team operates within an agile framework, focusing on continuous delivery, built-in quality, and strong engineering practices.

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

Bachelor’s degree in Software/Engineering or a related field.

Strong experience with React.js and its ecosystem.
