class=\"wp-block-list\">\n<li><strong>Ambiguous ownership boundaries<\/strong> between ML teams, platform, data, and SRE causing gaps in incident response.<\/li>\n<li><strong>High variance in ML workflows<\/strong> (different frameworks, data patterns, deployment targets) making standardization difficult.<\/li>\n<li><strong>Data instability<\/strong> (schema changes, freshness issues,

class=\"wp-block-list\">\n<li>Manual model promotion approvals without clear criteria or automation.<\/li>\n<li>Lack of reproducibility due to weak dataset\/version capture.<\/li>\n<li>Limited observability: inability to tie model behavior changes to business outcomes.<\/li>\n<li>Dependence on a few experts to maintain bespoke pipelines (\u201chero culture\u201d).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Anti-patterns<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Treating ML models as \u201cspecial artifacts\u201d that bypass normal software release rigor.<\/li>\n<li>Shipping models without rollback strategies or canarying for high-impact services.<\/li>\n<li>Monitoring only infra metrics (CPU\/memory) while ignoring model\/data behavior (drift, input anomalies).<\/li>\n<li>Allowing feature generation to be duplicated and inconsistent across online\/offline contexts.<\/li>\n<li>Overbuilding a platform without adoption focus (platform \u201civory tower\u201d).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Common reasons for underperformance<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Focus on tooling rather than outcomes (adoption, reliability, lead time).<\/li>\n<li>Insufficient stakeholder alignment leading to \u201cstandards no one uses.\u201d<\/li>\n<li>Weak incident leadership and inability to drive root-cause remediation.<\/li>\n<li>Over-optimization for one team\u2019s workflow at the expense of broader scalability.<\/li>\n<li>Lack of documentation and enablement, resulting in low platform leverage.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Business risks if this role is ineffective<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Increased customer-impacting incidents and

but varies in scope and emphasis.<\/p>\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>Small company (startup):<\/strong><\/li>\n<li>More hands-on \u201cfull-stack\u201d MLOps: building pipelines, serving, infra, and monitoring with minimal specialization.<\/li>\n<li>Faster decisions; fewer formal governance steps.<\/li>\n<li>Higher tradeoff pressure between \u201cship now\u201d and \u201cbuild right.\u201d<\/li>\n<li><strong>Mid-size scale-up:<\/strong><\/li>\n<li>Standardization and platform adoption become the dominant

auditability, and change management.<\/li>\n<li>Multi-tenant platform design, access controls, and integration with enterprise systems (ITSM, CMDB) become important.<\/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>General software\/SaaS (default):<\/strong> focus on reliability, velocity, cost, and customer experience.<\/li>\n<li><strong>Financial services\/healthcare (regulated):<\/strong> heavier governance, audit readiness, stricter data access, model risk tiering (context-specific).<\/li>\n<li><strong>Adtech\/marketplaces:<\/strong> high-throughput, low-latency serving; advanced experimentation and real-time monitoring.<\/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>Role is broadly global; variations arise mainly from:<\/li>\n<li>Data residency requirements (certain regions)<\/li>\n<li>On-call coverage models (distributed teams)<\/li>\n<li>Vendor\/tool availability and procurement practices<\/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> emphasis on platform as internal product with adoption metrics, SLAs, and roadmap management.<\/li>\n<li><strong>Service-led \/ consulting-heavy IT org:<\/strong> more bespoke deployments per client, stronger emphasis on portability, repeatable delivery kits, and multi-environment deployment automation.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Startup vs enterprise<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Startup:<\/strong> speed and pragmatism; fewer formal approvals; principal may act like a platform founder.<\/li>\n<li><strong>Enterprise:<\/strong> governance and scale; principal may spend more time on standards, architecture reviews, and

on reliability\/velocity; governance is lighter and more pragmatic.<\/li>\n<li><strong>Regulated:<\/strong> formal model documentation, approvals, audit logs, access reviews, retention policies, and potentially explainability monitoring.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">18) AI \/ Automation Impact on the Role<\/h2>\n\n\n\n<h3

(multi-tenancy, isolation, governance design).<\/li>\n<li>Risk-based judgment and tradeoff decisions (speed vs safety; controls vs friction).<\/li>\n<li>Cross-functional alignment and influencing adoption across teams.<\/li>\n<li>Incident command decisions during ambiguous outages (data vs model vs infra) and business-impact triage.<\/li>\n<li>Designing governance that is auditable and realistic for engineering teams to follow.<\/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>From building pipelines to governing systems of pipelines:<\/strong> more automation will generate and maintain \u201cstandard\u201d components, shifting focus to platform design, controls, and reliability engineering.<\/li>\n<li><strong>Increased evaluation sophistication:<\/strong> organizations will require continuous offline\/online evaluation, automated red-teaming (where relevant), and safety\/quality gates.<\/li>\n<li><strong>LLM\/agent operations become mainstream:<\/strong> prompt\/versioning, tool-use observability, and safety monitors expand the MLOps scope beyond classical models.<\/li>\n<li><strong>More policy-as-code:<\/strong> governance requirements will increasingly be enforced automatically in CI\/CD, reducing manual approvals but increasing the need for careful rule design.<\/li>\n<li><strong>Greater emphasis on supply chain security:<\/strong> provenance, attestations, and dependency integrity will become standard expectations for ML artifacts and containers.<\/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 design standardized evaluation harnesses and interpret their results for release decisions.<\/li>\n<li>Stronger expertise in operating distributed, compute-intensive workloads cost-effectively.<\/li>\n<li>Broader collaboration with security and governance stakeholders as AI risk management matures.<\/li>\n<li>Managing platform usability so that automation reduces toil rather than creating opaque, hard-to-debug systems.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">19) Hiring Evaluation
