Data Scientist

Data Scientist Tam Zamanlı / istanbul

İş Tanımı

At MAC, we believe in the power of data to transform experiences—both in the gym and across our digital platforms. As a Data Scientist, you'll be at the forefront of turning complex datasets into clear, actionable insights that drive growth, retention, and innovation.

Data is not a support function here — it's a core driver of how we make decisions. We move fast from insight to action, and data-driven outputs have a direct line to business decisions across product, growth, and operations. You'll work under the guidance of the Data & Analytics Manager and collaborate closely with the Product, Growth, and Engineering teams. This is not a narrowly defined modeling role — you'll be expected to contribute across the full spectrum of data work: analysis, modeling, reporting, and building analytical solutions that create real business impact. You'll also help bridge data science and growth by using event-level analytics and omni-channel engagement tools to turn insights into measurable outcomes across our app, web, and offline touchpoints.

 

Key Responsibilities


  • Own the end-to-end model development lifecycle — from data collection and preprocessing (including web crawling when necessary) to model training, evaluation, deployment, and ongoing maintenance
  • Build predictive models to support personalization, churn prevention, pricing, and campaign optimization efforts
  • Ensure the quality and longevity of delivered work; we value outputs that are built to last, not revisited repeatedly
  • Design and evaluate A/B tests and other controlled experiments
  • Explore large datasets to uncover patterns and opportunities for growth or efficiency
  • Develop and maintain scalable services and pipelines in alignment with software development best practices
  • Communicate findings clearly to both technical and non-technical stakeholders
  • Apply MLOps principles to ensure models are production-ready, monitored, and maintainable over time
  • Contribute to building a scalable and reusable data science toolkit within MAC

What We're Looking For

 

  • 5+ years of hands-on experience in data science or a closely related field
  • Proven ability to work across the full data lifecycle — from raw data acquisition to analytical reporting and end-to-end solution delivery
  • Strong background in statistics, machine learning, and predictive modeling
  • Hands-on experience with MLOps practices: model versioning, monitoring, retraining pipelines, and deployment workflows
  • Familiarity with recommendation systems, clustering, or time series forecasting
  • Proficiency in Python (Pandas, Scikit-learn, PyTorch, TensorFlow, etc.) and SQL
  • Experience developing and deploying models on cloud platforms (GCP, AWS, or Azure preferred)
  • Familiarity with service development and software delivery cycles — you understand what it means to ship sustainable, maintainable work
  • Detail-oriented with a strong sense of ownership over output quality; you care about getting it right, not just getting it done
  • Curiosity to explore emerging technologies such as generative AI, agentic AI, or LLMs
  • Experience with experimentation and A/B testing
  • A strong product and growth mindset, with hands-on experience using GA4, event-based product analytics, and omni-channel marketing/engagement tools
  • Experience with marketing technology platforms such as Insider is a plus
  • Experience in digital product analytics or subscription-based businesses is a strong plus
  • Fluent in English and Turkish
