How to Become a AI Engineer

AI engineers build LLM-powered features: retrieval pipelines, tool calling, evaluation harnesses and cost/latency tuning. The fastest-growing STEM title in the US market. Day to day, the work splits between building new capability and keeping existing systems trustworthy — the ratio shifts toward the latter as a company matures.

Interviews for these roles are usually four to six stages: recruiter screen, a technical screen on LLMs or RAG, a deeper practical or design round, and a hiring-manager conversation about scope and ownership.

Months 1–4: get fluent in LLMs and RAG. Build two projects that you could explain end to end in an interview, including what you'd change under load.

Months 5–8: add Python and Vector Databases. Start reading real job descriptions weekly and note the vocabulary gaps between them and your resume.

Months 9–12: apply in volume within the first 72 hours of a posting going live, tailor each resume to the posting's exact terms, and run every version through an ATS check before submitting.
