Senior / Lead AI Research Engineer (Agents Team)

Join Aily, a cutting-edge AI company, as a Senior/Lead AI Research Engineer. In this role, you will work on high-impact projects that directly influence our end product, focusing on Language Models and Agentic AI. You will have the opportunity to dive deep into model architectures, debug complex algorithmic behaviors, fine-tune state-of-the-art models, and translate your findings into deployable product enhancements. You will also have the chance to publish your findings in top-tier AI conferences.

• Design, set up, and execute experiments focusing on LLMs, Agentic AI, model fine-tuning, and broader ML systems.
• Deliver projects with a high degree of autonomy, present results clearly, explain the AI behind your findings, and align experiments with team priorities.
• Supervise and mentor team members, delegate tasks effectively, and drive the adoption of impactful research innovations across broader engineering teams.
• The Communicator: You can present complex research results clearly to both highly technical peers and non-technical business stakeholders
• The Tech Stack & Tools: You have extensive, highly proficient experience with Python and SQL. You possess a strong track record working with Language Models, Agentic AI workflows, and deep expertise in model fine-tuning (experience with Knowledge Graphs is a plus)
• The Academic Background: A Master's degree (required) in a highly technical and quantitative field such as Mathematics, Physics, Engineering, Computer Science, or a rigorous double degree
• The Foundations (All of ML): You have zero gaps in your machine learning fundamentals. While you will work extensively with LLMs, you have a deep, mathematical intuition for classical ML, deep learning, and how models learn (and fail) across the board
• Applicants must already have the legal right to work in Spain
• MLOps: You are not just a researcher; you are highly capable of deploying solutions into production environments using tools like Docker and other containerization technologies
• The Mindset (Autonomous & Sharp): You are exceptionally smart, highly autonomous, and thrive in ambiguity. You don't just wait for instructions; you proactively identify problems and rigorously test solutions. You keep up to date with the latest SOTA technology and research breakthroughs
• A Ph.D. in a relevant technical field is a strong plus
• Publication record at top-tier AI/ML conferences/journals
• Previous experience in academic or industrial AI research labs
