  • Model Deployment: Experience deploying ML models via APIs, containers (Docker, Kubernetes), or cloud endpoints.
  • Version Control & CI/CD: Git, Jenkins, or GitHub Actions.
  • Bonus: Exposure to Deep Learning, NLP, or Computer Vision frameworks.

Soft Skills

  • Strong problem-solving and analytical skills.
  • Excellent communication and collaboration with both technical and business stakeholders.
  • Proactive and curious mindset, with the ability to learn and adapt quickly.
  • Strong documentation and presentation abilities.

Minimum Qualifications

  • Bachelor's or Master's degree in Computer Science, Data Science, Statistics, Applied Mathematics, or a related field.
