legal\/compliance exposure in sensitive AI use cases.<\/li>\n<li>Loss of trust in AI features, reducing adoption and ROI.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">17) Role Variants<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">By company size<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Startup (early AI team):<\/strong><\/li>\n<li>Role may combine evaluation + monitoring + experimentation analytics.<\/li>\n<li>More hands-on building from scratch; fewer formal governance requirements.<\/li>\n<li><strong>Mid-size growth company:<\/strong><\/li>\n<li>Strong emphasis on reusable evaluation frameworks and automation.<\/li>\n<li>Works closely with multiple product teams and a growing MLOps function.<\/li>\n<li><strong>Enterprise-scale org:<\/strong><\/li>\n<li>More formal model risk management, documentation, and auditability.<\/li>\n<li>May operate as part of a centralized \u201cModel Quality\u201d or \u201cAI Trust\u201d function.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">By industry<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>B2B SaaS (common default):<\/strong><\/li>\n<li>Focus on reliability, explainability (customer trust), and measurable business outcomes.<\/li>\n<li><strong>Regulated (finance\/health):<\/strong><\/li>\n<li>Stronger governance, audit trails, fairness, and documentation requirements.<\/li>\n<li>More formal sign-offs and evidence retention.<\/li>\n<li><strong>Consumer internet:<\/strong><\/li>\n<li>Higher scale, strong emphasis on ranking\/recommendation, experimentation velocity, safety for user-generated content.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">By geography<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Generally consistent globally, but variations occur in:<\/li>\n<li>Privacy laws and data retention requirements<\/li>\n<li>Localization needs (language evaluation, region-specific behavior)<\/li>\n<li>Vendor availability for labeling and compliance requirements<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Product-led vs service-led company<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Product-led:<\/strong><\/li>\n<li>Emphasis on scalable frameworks, automation, and repeatability across product lines.<\/li>\n<li><strong>Service-led \/ consulting-heavy:<\/strong><\/li>\n<li>More bespoke evaluation per client; heavier documentation and client-facing reporting.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Startup vs enterprise operating model<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Startup:<\/strong> faster iteration, fewer gates, evaluation must be lightweight and high leverage.<\/li>\n<li><strong>Enterprise:<\/strong> layered controls, portfolio governance, and stronger need for consistent evidence.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Regulated vs non-regulated environment<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Non-regulated:<\/strong> pragmatic guardrails; focus on customer outcomes and operational quality.<\/li>\n<li><strong>Regulated:<\/strong> evaluation artifacts may be required for audits; more formal risk tiers and sign-offs.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">18) AI \/ Automation Impact on the Role<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Tasks that can be automated (increasingly)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Routine metric computation and report generation.<\/li>\n<li>Regression checks and gating in CI\/CD.<\/li>\n<li>Data validation checks (schema drift, missingness, distribution changes).<\/li>\n<li>Synthetic test case generation (especially for NLP\/LLM scenarios) to expand coverage.<\/li>\n<li>Automated triage summaries for incidents (log analysis + clustering).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Tasks that remain human-critical<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Defining what \u201cquality\u201d means in product context and balancing trade-offs.<\/li>\n<li>Designing evaluation strategies that anticipate real-world misuse or edge cases.<\/li>\n<li>Interpreting ambiguous results and deciding what risks are acceptable.<\/li>\n<li>Negotiating metric definitions and thresholds across stakeholders.<\/li>\n<li>Ensuring fairness\/safety evaluations are meaningful and not reduced to checkbox metrics.<\/li>\n<li>Establishing trust: stakeholders need confidence in the evaluator\u2019s judgment and rigor.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How AI changes the role over the next 2\u20135 years<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Evaluation becomes more continuous and policy-driven:<\/strong> tests codify behavioral requirements, not just accuracy metrics.<\/li>\n<li><strong>LLM\/agent evaluation becomes a major component<\/strong> in organizations shipping assistants, copilots, or automated workflows.<\/li>\n<li><strong>Hybrid evaluation stacks emerge:<\/strong> automated judging + targeted human review + production telemetry feedback loops.<\/li>\n<li><strong>Evaluation as a platform:<\/strong> reusable services, dashboards, and test repositories become first-class internal products.<\/li>\n<li><strong>Greater emphasis on adversarial and misuse testing:<\/strong> red teaming becomes integrated with standard evaluation, especially for customer-facing generation.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">New expectations caused by AI, automation, or platform shifts<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ability to evaluate systems with non-determinism (LLMs) using robust sampling strategies and variance handling.<\/li>\n<li>Governance-ready evidence packages for enterprise customers.<\/li>\n<li>Stronger collaboration with security and privacy due to new AI risks.<\/li>\n<li>Evaluation coverage expands beyond model outputs to end-to-end workflows (retrieval, tools, orchestration, UX).<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">19) Hiring Evaluation Criteria<\/h2>\n\n\n\n<h3
