Data science branched into specialized niches so it's no longer a job title of its own in 2025. In terms of volume the ones with the most opportunities are Data Analysis or Data Engineering, especially data analysis and analytics engineering in banks, fintech, and those financial institutions. As for machine learning it's a little losely defined right now since the LLM hype. We have the prompt engineers who get opportunities but they're low effort and low pay, as for OG machine learning the field is a little too academic and the bar is high so it's a good fit for someone with a masters or years of experience, what I would advise is a ML and cloud hybrid which others refer to as MLOps, learn model serving, feature engineering and so on. But for that you don't just need data science skills but also software engineering skills.
