Senior Python Developer - Microservices & Node.js

Have you dreamed of making an impact in a global environment that values curiosity, innovation, and growth? If this sounds like you, welcome, you’re already an ERNIan 🚀.

Can you imagine contributing to a high-impact platform built in the industrial sector? 🚀

Join our expert team to work on a modern, cloud-native platform, contributing to the design and development of scalable microservices and distributed systems. You will apply your knowledge to build secure, reliable and high-performance backend services.

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 building microservices with Python (FastAPI), Node.js (NestJS) or Go.
• Deep understanding of system architecture, security, performance and reliability.
• Experience designing and maintaining REST APIs in production.
• Hands-on experience deploying services on Kubernetes (preferably AKS).
• Proficiency with CI/CD pipelines, ideally GitHub Actions.

You will be responsible for designing and maintaining microservices and REST APIs while deploying services on Kubernetes and Azure. Creating secure Docker images and implementing observability to ensure reliability. Working closely with the Tech Lead to review code, document decisions and drive continuous improvements.

What if the project ends?😅

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.

Our working model 👩‍🔬

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!
