  • Take ownership of both the Android (Frontend) components, including user-facing predictive diagnostics and actionable insights, and the Backend infrastructure (Microservices) necessary for large-scale data ingestion, model serving, and continuous learning.
  • Clean and manage large datasets for model training.
  • Version, track, package, and deploy models into a production environment, treating ML models as first-class citizens in a CI/CD pipeline.
  • Unit and integration testing code for robustness, including edge cases, usability, and general reliability.
  • Bug fixing and improving application performance.
  • Collaborating with cross-functional teams to define, design, and ship new features.

  • Theoretical and practical knowledge of Machine Learning algorithms, Deep Learning concepts, and Neural Network Architectures.
  • Familiarity with major AI/ML Frameworks like TensorFlow and PyTorch.
  • Experience with Large Language Models (LLMs), including using and integrating APIs, and applying techniques like Retrieval-Augmented Generation (RAG)
  • You have experience/knowledge with working in an agile environment.
  • You have experience/knowledge working with software development tools such as Git, Gerrit, Gitlab and Jenkins.
  • Excellent debugging skills to solve challenging problems.
  • Experience working with remote data via REST, JSON and XML.

  • You will join Fairphone’s collective pension scheme, and we will contribute to building your pension.
  • You will receive a MacBook, Fairbuds, and a Fairphone as working devices.
