What the work actually involves
An AI Engineer may spend one day improving retrieval evidence, another debugging a failed tool call, and another building an evaluation set with a domain expert. The role sits between software engineering, data, product and risk. The job is not to make every task agentic; it is to choose the simplest reliable design and prove that it works.
APIs, retrieval, tools, workflows and model integrations.
Datasets, rubrics, regression checks and error analysis.
Tracing, latency, cost, reliability and incident response.
Permissions, approvals, data boundaries and safe failure.
Competency progression
| Area | Entry | Working | Advanced |
|---|---|---|---|
| Software | Python, HTTP, Git, SQL | Async APIs, testing, containers | Distributed reliability and platform patterns |
| AI systems | Prompting and structured output | Retrieval, tools, orchestration | Architecture across multiple agents and services |
| Evaluation | Manual test cases | Dataset and rubric-based regression | Online evaluation, experiment design and governance |
| Safety | Input validation and secrets | Least privilege, approvals, threat models | Cross-system controls and incident leadership |
| Product judgment | Explain a user story | Define success and trade-offs | Shape strategy with evidence and risk |
Portfolio projects that prove readiness
- Grounded support agent: evidence-linked answers, permissions, ticket tool and human escalation.
- Evaluation harness: representative dataset, tool assertions, rubric scoring and regression report.
- MCP integration: a narrow server with authorization, input validation, audit logs and threat model.
For each project, publish the problem, architecture, rejected alternatives, test results, known limitations and operating plan. Employers need evidence of judgment, not a list of frameworks.
Typical interview loop
Loops vary by employer. Expect questions about software fundamentals, retrieval and tool use, evaluation, system trade-offs, safety and how you investigated a failure.
