Level Data Scientist Greece

Satalia; United States; Remote; USD 51,000 - 73,000; Full time

Job summary

Satalia, fully remote in Greece, seeks a Data Scientist to design and deploy ML/AI models in production, including LLM-powered systems. The role emphasizes end-to-end ownership—from data handling to evaluation—collaborating with engineers and stakeholders across the organisation.

The ideal candidate has 2–5 years of production ML experience, strong modelling skills, and solid software engineering habits. Expect impactful projects and continuous learning in a global, research-driven environment.

Qualifications

• 2–5 years building ML/AI models in production.
• Strong modelling skills for both structured and unstructured data.
• Hands-on experience building LLM-powered systems.
• Good software engineering habits: Python, version control, testing, code review.
• Clear communication with both technical and non-technical stakeholders.
• Experience with temporal and geospatial data.
• Experience building and testing agents.

Responsibilities

• Own well-defined components of a project, from data and modelling to evaluation.
• Develop models, agents, and the evaluation harnesses that keep them safe and reliable.

Job description

Data Scientist, Greece Role type: Full time | Location: Greece (fully remote) | Preferred start date: ASAP Satalia builds enterprise-grade AI systems for WPP and its FTSE 100 client base. Led by WPP Chief AI Officer Daniel Hulme, we run as a decentralised organisation where engineers and scientists own their domains end to end. Our data scientists are also at the core of WPP Research, conducting frontier research and developing prototypes that evolve into tools used in production across WPP.

Our current work includes:

• Agentic systems. Developing long-horizon agents that plan, use tools, and collaborate.
• Federated and privacy-preserving learning. Training shared models when the data cannot move: federated LLM fine-tuning across independent data owners, and aggregation strategies that hold up under heterogeneous datasets.
• Identity intelligence. Predictive and probabilistic modelling on large behavioural datasets: propensity and similarity models, and probabilistic record linkage across data sources.
• Geospatial intelligence. Spatial statistics, geospatial feature engineering, and forecasting and optimisation over location data, plus computer vision on imagery.
• Synthetic data. Generating realistic synthetic data with known ground truth to stress-test models and agents under controlled adversarial conditions.
