class=\"wp-block-list\">\n<li><strong>Misaligned expectations:<\/strong> stakeholders expect \u201cAI magic\u201d without data readiness or product changes.<\/li>\n<li><strong>Data quality and lineage gaps:<\/strong> models degrade silently due to upstream changes and weak contracts.<\/li>\n<li><strong>Tool sprawl:<\/strong> multiple experiment trackers, registries, and pipelines causing duplication and friction.<\/li>\n<li><strong>Unclear ownership:<\/strong> \u201cwho owns the model in production?\u201d leads to poor operations and slow fixes.<\/li>\n<li><strong>Latency\/cost constraints:<\/strong> models that look great offline fail in real-time performance or cost budgets.<\/li>\n<li><strong>Governance vs speed tension:<\/strong> too much bureaucracy slows delivery; too little increases risk.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Bottlenecks<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Limited access to high-quality labeled data or feedback loops<\/li>\n<li>Lack of MLOps maturity causing manual deployments and inconsistent reproducibility<\/li>\n<li>Under-instrumented product experiences (no reliable online

class=\"wp-block-heading\">Anti-patterns<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Shipping models without monitoring, rollback strategy, or retraining triggers<\/li>\n<li>Treating ML as a separate \u201cresearch org\u201d disconnected from product delivery<\/li>\n<li>Measuring only offline metrics without online validation<\/li>\n<li>Over-optimizing for novelty (new architectures) instead of outcomes and reliability<\/li>\n<li>Central team becomes a ticket queue; no platform reuse; excessive handoffs<\/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>Weak prioritization and inability to say \u201cno\u201d to low-value projects<\/li>\n<li>Lack of production experience leading to fragile systems<\/li>\n<li>Poor cross-functional influence; constant conflict with Product\/Data\/Security<\/li>\n<li>Failure to build a talent bench (hiring too slow, misleveling, no growth paths)<\/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>Revenue loss from degraded

class=\"wp-block-list\">\n<li><strong>Startup \/ small scale:<\/strong> <\/li>\n<li>More hands-on: the Head of ML may still code, build prototypes, and directly implement MLOps.  <\/li>\n<li>Governance is lightweight; focus is on shipping and finding product-market fit with ML features.<\/li>\n<li><strong>Mid-size software company:<\/strong> <\/li>\n<li>Balanced scope: manages multiple teams, builds platform capabilities, and partners deeply with Product.  <\/li>\n<li>Strong emphasis on measurable outcomes and standardization.<\/li>\n<li><strong>Large enterprise \/ multi-product:<\/strong> <\/li>\n<li>Portfolio complexity and governance increase substantially.  <\/li>\n<li>More time on operating model, compliance, vendor management, and executive alignment; less hands-on.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">By industry (kept software\/IT oriented)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>B2B SaaS:<\/strong> focus on personalization, workflow automation, forecasting, and enterprise trust requirements.<\/li>\n<li><strong>Consumer software:<\/strong> stronger emphasis on large-scale ranking\/recommendation, real-time experimentation, and low-latency serving.<\/li>\n<li><strong>IT \/ internal platforms:<\/strong> focus on operational analytics, anomaly detection, capacity forecasting, and automation for internal efficiency.<\/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>Core expectations are global; variations appear in:<\/li>\n<li>Data residency requirements<\/li>\n<li>Vendor availability and contractual constraints<\/li>\n<li>Hiring market competitiveness and team distribution (follow-the-sun operations)<\/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> ML integrated into product roadmap; strong A\/B testing and UX partnership; emphasis on user outcomes.<\/li>\n<li><strong>Service-led \/ IT services:<\/strong> ML often delivered as projects; more emphasis on solution architecture, repeatable templates, client governance, and delivery assurance.<\/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> prioritize speed and experimentation; minimal viable governance; build vs buy tradeoffs favor managed services.<\/li>\n<li><strong>Enterprise:<\/strong> formal lifecycle, approvals, auditability, change management; more focus on platform reuse and risk controls.<\/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>Regulated\/high-risk:<\/strong> formal model risk management, documentation, fairness testing, approvals, and audit trails become core deliverables.<\/li>\n<li><strong>Non-regulated:<\/strong> lighter controls, but still needs operational monitoring, privacy compliance, and customer trust practices.<\/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

evaluation and regression testing:<\/strong> standardized metric computation, dataset versioning checks, and threshold gates.<\/li>\n<li><strong>Operational triage support:<\/strong> AI-assisted incident summarization, anomaly detection on logs\/metrics, suggested runbooks.<\/li>\n<li><strong>Documentation drafts:<\/strong> automated generation of model cards, change logs, and architecture summaries (still requires human validation).<\/li>\n<li><strong>Code review assistance:<\/strong> static analysis, security checks, and style conformance for ML codebases.<\/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><strong>Strategy and prioritization:<\/strong> deciding what to build, why, and what to stop.<\/li>\n<li><strong>Risk judgment:<\/strong> responsible AI tradeoffs, privacy constraints interpretation, and ethical decisions.<\/li>\n<li><strong>Cross-functional leadership:<\/strong> negotiation, alignment, and executive narrative building.<\/li>\n<li><strong>Accountability for outcomes:<\/strong> interpreting ambiguous results, making rollout decisions, and owning consequences.<\/li>\n<li><strong>Org design and talent development:<\/strong> coaching, performance management, and culture building.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">How AI changes the role over the next 2\u20135 years (current-to-near future, realistic)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Shift from \u201cbuild models\u201d to \u201cbuild AI systems\u201d:<\/strong> multi-model orchestration, retrieval + generation patterns, and agent-like workflows become more common.<\/li>\n<li><strong>Higher governance expectations:<\/strong> model lineage, evaluation, and safety will be expected even for LLM-based features; enterprises will standardize controls.<\/li>\n<li><strong>Greater emphasis on cost management:<\/strong> inference spend can scale rapidly; leaders will be measured on unit economics and performance engineering.<\/li>\n<li><strong>Evaluation becomes a competitive advantage:<\/strong> organizations that can reliably measure quality (including LLM outputs) will ship faster and safer.<\/li>\n<li><strong>Platform consolidation:<\/strong> standard toolchains and internal platforms reduce sprawl; the Head of ML will drive rationalization.<\/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 third-party foundation models\/vendors with disciplined benchmarks and risk controls<\/li>\n<li>Stronger security posture against AI-specific threats (prompt injection, data leakage, supply chain issues)<\/li>\n<li>Faster iteration cycles without compromising reliability (automated gates + strong monitoring)<\/li>\n<li>Operational maturity for AI features: fallbacks, safe defaults, and observable behavior in production<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">19) Hiring Evaluation Criteria<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">What to assess in
