job career

**Job** Career paths in AI span research, engineering, and emerging specialized roles, each requiring distinct skill sets and offering different opportunities to contribute to the field. Research roles (Research Scientist, Research Engineer): focus on advancing fundamental capabilities; require strong publication track record, deep ML theory, and PhD often preferred; industry labs (Google DeepMind, Meta FAIR, OpenAI) and academia. ML Engineer: builds production systems using ML; requires software engineering skills, MLOps knowledge, and ability to deploy and maintain models at scale; most numerous AI role. Applied Scientist: bridges research and engineering; applies latest techniques to business problems. Prompt Engineer: emerging role focused on designing effective prompts and instruction tuning; requires understanding of LLM behavior and systematic evaluation. AI Safety: focuses on alignment, interpretability, and ensuring AI systems work as intended; growing rapidly in importance. Building your profile: contribute to open source (shows real skills), build portfolio projects (end-to-end demonstrations), write technical content (demonstrates communication), and engage with community. Interview prep: coding (LeetCode-style), ML fundamentals, system design, and domain-specific knowledge. The field evolves rapidly—continuous learning is essential.
