- We are looking for exceptionally smart and driven AI Research Engineers to join a small, highly technical, and specialized research team at Aily

- This team operates at the bleeding edge of AI, focusing on high-impact, moderately higher-risk projects that directly influence our end product. While your day-to-day work will heavily involve Language Models and Agentic AI, we expect you to be deeply versed in all of Machine Learning

- You will have the runway 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

- While our ultimate goal is delivering business value, we maintain a strong culture of scientific rigor. If an experiment yields novel, high-quality results, you will have the opportunity and support to publish your findings in top-tier AI conferences (e.g., NeurIPS, ICLR, ACL)

- Experiment &
- Build: Design, set up, and execute experiments focusing on LLMs, Agentic AI, model fine-tuning, and broader ML systems. Manage reproducible research pipelines, version code, and data, and select the right frameworks for prototyping

- Algorithmic Debugging: Actively investigate why a model isn’t converging, why outputs are inconsistent, or why results are unreliable across different ML architectures

- Code Quality: Write clean, modular code (effective use of classes, functions, and documentation) following strict software engineering best practices

- Autonomous Delivery: Deliver projects with a high degree of autonomy. Present results clearly, explain the AI behind your findings, and align experiments with team priorities

- End-to-End Ownership &

- Strategy: Deliver clean, extendable research pipelines end-to-end. Set and drive the overall research strategy based on expected business leverage, identifying domain-wide opportunities

- Bridge Research &

- Product: Translate experimental findings and research breakthroughs into clear, actionable, and deployable directions for the Data Science, MLE, and Product teams

- Mentorship &





- Leadership: Supervise and mentor team members, delegate tasks effectively, and drive the adoption of impactful research innovations across broader engineering teams

- Advanced Systems &

- MLOps: Utilize advanced knowledge of MLOps to define and develop robust E2E code pipelines for cutting-edge models

- External Presence: Act as a representative of Aily’s research efforts, build university relationships, and spearhead efforts to publish papers at top conferences

Benefits

- Integral company and culture

- Hybrid working model
- Fast growth path- 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
