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.

• Experience designing, developing, and implementing AI Engineering solutions (APIs, cloud, LLMs, Agents, ML models).

• Experience in Context/Prompt Engineering, LLM Monitoring and Observability, RAG systems

• Solid programming skills in Python and Backend/API development, Data Science and/or Cloud platforms (AWS or Azure).

• Proactive mindset and strong drive for continuous learning.

• Strong communication skills in client facing contexts.

• Experience designing and deploying AI solutions in production.

You will responsible for designing and delivering production-ready AI solutions for clients, defining scalable architectures and ensuring engineering excellence.
