Job description

Can you imagine bringing AI solutions into production and transforming real business processes in the insurance sector?

Join our expert team to work on a project in the Insurance Sector, contributing to the development and deployment of scalable, production-ready AI solutions that improve business processes. You will apply your knowledge of Python, LLMs, AI Agents and cloud-native technologies to build reliable services, integrations and intelligent applications.

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 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 software engineering experience delivering production-ready solutions across backend, frontend, data and operations.

Hands‑on knowledge of Python, APIs, LLM integrations, AI agents and modern AI technologies.

Experience with cloud-native environments, CI/CD pipelines, containers, Kubernetes and secure coding practices.

Ability to work across unfamiliar codebases, design integrations and ensure testing, observability and reliability in regulated environments.

Strong communication skills, fluent English and a degree in Computer Science, Engineering or equivalent professional experience.

You will be responsible for collaborating with technical and business experts to translate complex challenges into production-ready AI solutions. Designing and extending reusable AI components while developing custom services, integrations and intelligent agents. Taking ownership of the development and deployment lifecycle across different technology stacks. Ensuring security, reliability and documentation while contributing to scalable engineering practices.

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!
