Poland · Full-time · Not Applicable
Fetcherr experts in deep learning, algo-trading, e-commerce, and digitization, Fetcherr disrupts traditional systems with its cutting-edge AI technology. At its core is the Large Market Model (LMM), an adaptable AI engine that forecasts demand and market trends with precision, empowering real-time decision-making. Specializing initially in the airline industry, Fetcherr aims to revolutionize industries with dynamic AI-driven solutions.

While our initial focus has been the airline industry, Fetcherr is rapidly expanding its impact across a variety of sectors with scalable, AI-powered solutions that drive efficiency and profitability.

We are seeking a detail-oriented and collaborative ML Engineer to help support and maintain our machine learning capabilities. This role is ideal for someone who enjoys working closely with production systems, ensuring reliability, scalability, and explainability of models while enabling research teams to deliver impact faster.

Responsibilities

  • Collaborate with cross-functional teams to ensure ML systems remain robust, explainable, and aligned with business needs.
  • Monitor and report on ML model performance, reliability, and explainability metrics.
  • Extend and scale monitoring pipelines, including support for new features in development.
  • Investigate, troubleshoot, and resolve issues in production ML workflows (tiered support from initial triage to root-cause analysis with model owners).
  • Develop and maintain repositories for feature engineering, inference monitoring pipelines, and artifact monitoring tools.
  • Perform exploratory data analysis (EDA) on historical datasets to identify quality issues and maintain data health.
  • Implement and oversee production based adjusters across customer deployments.
  • Evaluate and track critical ML artifacts such as explainability files, coverage metrics, and alignment of features.
  • Support development and maintenance of internal tools (e.g., interfaces, registries, and feature monitoring frameworks).
  • Build and maintain static and temporal features, including seasonality, event-based, and price-related features.

Requirements:

You’ll be a great fit if you have:

  • 3+ years of hands-on experience in data science, ML operations, or applied ML support.
  • Proficiency in Python and standard data/ML libraries (Pandas, NumPy, Scikit-learn, SQL; experience with PyTorch or TensorFlow).
  • Strong data visualization and exploratory data analysis skills for monitoring and debugging pipelines.
  • Experience with time-series data and feature engineering.
  • Familiarity with explainability tools and model monitoring best practices.
  • Strong problem-solving skills with the ability to troubleshoot across data, code, and model workflows.
  • Excellent communication skills to summarize findings for both technical and non-technical audiences.
  • Experience with cloud-based ML platforms (GCP; experience with Vertex AI and/or PubSub is a plus).
  • Familiarity with containerization (Docker), CI/CD workflows, or ML observability tools.
  • Prior exposure to demand forecasting, pricing, or revenue management.
  • Bachelor's or Master's in Computer Science, Machine Learning, Statistics, Engineering or a relevant field.

If you’re excited about ensuring that machine learning systems are reliable, explainable, and production-ready in a fast-moving environment, we’d love to hear from you.
