About the Role
We are looking for a Confirmed Data Scientist to join our Delivery Optimization team, a core unit within Ogury’s AI organization. This team builds and improves the machine learning models that directly impact our performance and revenue: predicting clicks, video completions, auction wins, and forecasting for our media planning tools.
With a team of only 4 Data Scientists and MLOps currently handling a broad scope — from throttling and bid shading to pacing, deal optimization, and forecasting — we’re seeking a motivated Data Scientist to expand our capacity and accelerate innovation.
This role is ideal for someone with 1–3 years of experience in machine learning, who is eager to grow, thrives on modelization work, and wants to see their contributions deliver immediate, measurable business impact.
Why you will love this role
- Direct impact: your models will improve campaign performance, revenue, and profitability.
- Growth potential: we value promising junior/confirmed talent who want to evolve their skills and career.
- Collaboration: work alongside experienced data scientists, engineers, and product experts in Paris, Singapore, and beyond.
- Innovative environment: contribute to the modernization of our predictive AI stack and shape the next generation of Ogury’s AdTech platform.
- Work with very large datasets and high-scale in general (tens of Billions of daily predictions)
What you will be doing
- Develop and optimize predictive models (e.g., click-through rate, video completion, auction outcomes, media planning forecasts, …).
- Collaborate with engineers and data scientists to modernize Ogury’s predictive stack with state-of-the-art algorithms.
- Train, test, and refine models using tabular and categorical data.
- Maintain model registry and promotion pipelines through MLFlow.
- Contribute to real-time algorithmic decisioning systems (campaign pacing, bid shading, throttling, etc.).
- Work cross-functionally with stakeholders (AdOps, Product, Engineering) to ensure data science outputs are scalable and impactful.
What you will bring to Ogury
- 1–3 years of hands-on experience as a Data Scientist (early career experience welcome if strong fundamentals).
- Solid knowledge of machine learning modeling (mostly supervised, on tabular + categorical data).
- Proficiency in Python (mandatory).
- Experience with TensorFlow, Scikit-learn, and MLFlow.
- Strong analytical mindset, with the ability to manipulate data and train models effectively.
- Industry exposure to real-time backend systems (AdTech or similar high-scale environment) is a plus.
- Familiarity with Go, Scala, C, or C++ is a plus (not required).
- Growth mindset – eager to learn, adapt, and take ownership in a fast-paced scale-up environment.
Technical Stack
- Languages: Python (primary), Go/Scala/C/C++ (nice-to-have)
- Frameworks: TensorFlow, Scikit-learn, MLFlow, Airflow
- Focus Areas: Predictive modeling, algorithmic decisioning, optimization, real-time systems
