ML engineers command higher salaries because they require strong software engineering skills on top of ML knowledge. They own the full pipeline from training to production deployment, requiring systems thinking, performance optimization, and production reliability expertise that data scientists typically don't need.
If you enjoy coding, system design, and building production systems — go ML engineer. The pay ceiling is higher. If you prefer analysis, statistics, and business storytelling — data science may suit you better. Data scientists often transition to ML engineering roles after developing engineering skills.
Very common. Many ML engineers started as data scientists and upskilled in software engineering, distributed systems, and MLOps. The transition typically takes 1-2 years and comes with an immediate 15-25% salary bump.
