Senior Software Engineer - Python - Knowledge Graphs Pharma

We will discuss it during the first call. If it is important to you, feel free to ask! 💬

Can you imagine connecting enterprise knowledge with AI to deliver trusted answers in natural language? 🧠🔗

Join our expert team to work on a pharmaceutical-sector platform, contributing to the development of a semantic backend connecting enterprise knowledge graphs, AI agents and cloud data platforms.
You will apply your knowledge of Python and RDF/SPARQL to build reliable services that enable governed conversational analytics.

You will be responsible for owning the architecture and operational reliability of a semantic-layer MCP backend connecting knowledge graphs with AI agents and cloud data platforms. Optimizing SPARQL queries and caching for sub-second responses while extending a compiler that turns ontologies and business rules into semantic models and Text-to-SQL instructions. Ensuring security, observability and automated testing across OpenShift environments while supporting lifecycle documentation and releases

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 🤝

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.

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!
