About The Position ? Ready to shape the future of conversational analytics in clinical operations? ? Join our expert team to work on a clinical-operations data platform , contributing to the development of an enterprise-grade conversational analytics agent. You will apply your knowledge of Python, LLMs, Snowflake and AI Agents to build reliable, explainable and governed solutions that allow users to interact with data through natural language.

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.
