The AI Integration Engineer roadmap
Each topic below carries a study note, real reading, and practice questions in the app. A topic unlocks when you pass the one before it, so the order is the path, so you are never guessing what to learn next.
Phase 1AI integration foundations
APIs and SDKs
APIs are the contract; SDKs are maintained clients over them.
Authentication and rate limits
Credentials must live in a secrets manager, be rotated, and never enter source control.
Error handling and retries
Distinguish transient failures (5xx, timeouts) from deterministic ones (4xx).
Phase 2AI integration lLM
Model APIs
Chat/completion APIs use structured message roles (system, user, assistant) plus parameters like model and max tokens.
Streaming responses
Streaming delivers tokens incrementally over SSE so users see output immediately instead of waiting for the full completion.
Structured output and parsing
When downstream code consumes model output, constrain generation to a JSON schema via the provider's structured-output or tool feature, then validate the parsed object before use.
Phase 3Tools and MCP
Tool and function calling
Tool use lets a model invoke your functions via a name, description, and JSON-schema parameters.
Model Context Protocol (MCP)
MCP is an open standard for exposing tools and resources to LLM clients over a common protocol.
Tool granularity and design
Map one tool to one clear intent with typed parameters and a good name.
Phase 4AI integration orchestration
Multi-step workflows
Decompose dependent work into discrete steps with persisted state between them.
Idempotency and retries
Side-effecting calls (charges, record creation) need idempotency so retries do not duplicate effects.
Async and queues
For slow or spiky work, accept the request fast, enqueue a job, and process it with rate-controlled workers.
Phase 5AI integration in production
Observability
Instrument LLM integrations with structured, correlated traces per request: model, redacted prompt/response, tool calls, latency, token usage, and error type.
Cost and latency
Route requests to right-sized models, cache repeated identical calls, and trim prompt/context size, validating quality on each change.
Versioning and rollout
Pin explicit model versions instead of a floating 'latest' alias.

Coming from another job?
Most people on this path arrived from somewhere else: engineering, analysis, testing, product, support, compliance, design. Onboarding asks what you do today and builds a short starter run out of the gaps, so you begin from what you already know rather than from chapter one. See how it works.
