• Strong proficiency in Python
• 2–4 years of experience in machine learning or backend software development
• Hands‑on experience with ML frameworks (TensorFlow, PyTorch, Scikit‑learn)
• Solid understanding of ML workflows: data cleaning, model development, tuning, evaluation
• Familiarity with model deployment, API development, or real‑world ML product integration
• Experience with Jupyter, Colab, or cloud‑based ML platforms
• Strong analytical, problem‑solving, and communication skills
• Comfortable working remotely and collaborating across time zones

Nice to Have

• Experience with NLP, computer vision, or recommendation systems
• Familiarity with AWS, GCP, or Azure
• Exposure to Docker, Git, or CI/CD pipelines
• Background in high‑growth startups or agile product teams
