Data Scientist - LLMs & Conversational AI

Connexai; Manchester; In loco; GBP 60.000 - 95.000; Tempo pieno

Descrizione del lavoro

Connexai is searching for a Data Scientist to contribute to production conversational AI systems powered by large language models and speech AI. You will work with researchers and engineers to define, evaluate, and improve prompts, pipelines, and models, driving measurable AI outcomes in production.

The role emphasizes rigorous experimentation, data-driven decision making, and collaboration within a research-driven team advancing LLM-powered workflows and evaluation.

Competenze

• Degree, MSc, or PhD in Mathematics, Physics, Statistics, Computer Science, or a similarly quantitative field.
• Strong Python skills with experience using tools such as pandas, NumPy, and scikit-learn.
• Experience working with data science, experimentation, statistical analysis, or machine learning systems.

Mansioni

• Design and use datasets, experiments and evaluation methods to gain detailed and intimate knowledge of our conversational AI solutions.
• Identify opportunities to improve quality, reliability, and performance through research and experimentation.
• Statistically investigate how changes to prompts, pipelines, models, or system logic impact real-world outcomes.
• Think creatively about edge cases that might expose flaws in a system, and devise and test different ideas about how to handle those cases without harming global performance.
• Develop tests and metrics that capture the many nuances of user requirements, rather than uncritically relying on industry-standard proxies that might obscure underlying issues.
• Advance the building blocks behind LLM-powered systems, including classification, ranking, retrieval, scoring, and conversational workflows.
• Collaborate with engineering and evaluation teams to turn product problems into measurable AI problems.
• Stay up to date with the latest research and critically apply new ideas to production AI systems, separating out strong, flexible approaches from fragile hype.
