The Role
We're hiring several AI/ML Engineers for the Synthetic Data Platform team. This is a greenfield project, an exciting new market and a key part of Cint’s 2026 product strategy.
You will build models with a deep understanding of how respondents answer surveys. These will underpin new products which will be best-in-class for the industry, including:
Survey Augmentation: filling missing responses to surveys
Audience Profiling: predicting respondent characteristics from signals we have
Agentic Insights: answering a client’s research questions using insights from existing data
The Team
You'll join our AI/ML team in Prague, working alongside engineers on augmentation and profile modelling, the data science team, and a product manager who owns the Synthetic Data roadmap. Customer pilots are already running, and feedback from those pilots shapes the roadmap.
What You'll Do:
Build production augmentation and profile models: Design, train, evaluate, and deploy models against real survey data, owning the full path from experiment to production.
Innovate on solutions: We aim to build the best simulation of survey responses in the industry. You'll design the experiments, baselines, and models to get us there.
Use the latest technology: Build on the best open-weights LLMs with fine-tuning, build new ones from scratch with custom architectures or use third party models through an API; whatever gets us the best result.
Partner with Data Science: Work with the data science team to ensure integrity of our statistical testing and experiment framework.
Leverage AI tooling: Use Claude Code and agentic programming tools where appropriate.
What You Bring:
Strong knowledge of maths, probability, statistics and algorithms
Programming skills and be proficient in Python. Knowledge of Java is a plus.
Knowledge of traditional machine learning tools and techniques (support vector machines, gradient boosting)
An understanding of LLMs and their architecture, ideally with experience in fine-tuning, e.g. LoRA, distillation
Familiarity in SQL, knowledge of Databricks is a plus
Outstanding problem-solving and analytical skills
You like to push the limits of your knowledge every day
You own your conclusions and are comfortable presenting them and shaping outcomes
