You will be responsible for building, operating and evolving software within a cloud-based Data & Analytics Platform team.

You will navigate ambiguity and changing priorities, share knowledge and contribute to continuous improvements in products, processes and engineering practices

## Description

Join our expert team to work on a cloud-based Data & Analytics Platform, contributing to the development and evolution of enterprise software solutions.
You will apply your knowledge of AWS and Python, alongside SQL and Java, to build and operate software using modern distributed architectures.

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.
