Which "AI engineer" are you becoming?
Two career paths share the keyword. The ML track — model building, PyTorch, frequently a master's — is the longer road with the research-role ceiling; for that route, aitexas.org's step-by-step guide covers foundations, credentials, and specialization well. The automation track below gets you paid for orchestrating models in production — a different, shorter on-ramp that values operational judgment over research math. The stages that follow are the automation track; the fit check applies to both.
Before week 1 — an honest fit check
This roadmap assumes you can already use a computer fluently and are comfortable reading documentation that was not written for beginners. The sixteen-week figure assumes roughly ten focused hours a week; double the calendar if you have five. What it does not assume is a CS degree — the hiring signal in this field is a working system with error handling, not a credential. If you finish stage 2 and find you dislike debugging other people's APIs, stop there: that activity is most of the job.
Stage 1 — foundations (weeks 1–4)
- Learn HTTP basics: GET/POST, headers, JSON, status codes.
- Build a 3-step workflow: form → spreadsheet → email notification.
- Write a short Python or TypeScript script that calls a public API.
Stage 2 — integrations (weeks 5–10)
- Connect a CRM or support tool via OAuth or API key.
- Add branching, filters, and scheduled triggers.
- Implement retries and dead-letter handling for failed runs.
Stage 3 — LLM workflows (weeks 11–16)
- Call an LLM API with structured output (JSON schema or tool use).
- Build a human-in-the-loop review step for high-stakes outputs.
- Track token cost and latency per workflow run.
Stage 4 — production (ongoing)
- Store secrets in a vault or env manager—not in workflow UI fields.
- Ship runbooks: what breaks, who gets paged, how to replay.
- Document data flows for security and compliance questions.
Portfolio projects that interview well
Inbound lead enricher (clear business metric), support ticket classifier with escalation rules, or document intake pipeline with extraction plus human QA. Each should show diagrams, sample logs, and what you would improve next.
What to build as your portfolio piece
One system, boringly reliable, beats five demos. The strongest cheap signal is an automation that has run unattended for weeks and failed gracefully at least once: a lead-intake flow that survived a CRM outage and queued its retries, with a README that names the failure and the fix. Hiring managers in this niche read post-mortems the way designers read portfolios — the incident narrative is the credential. Keep run logs; they are your proof the thing actually ran.
