The deploy-seam restructure
- Inference & Performance EngineerEngineering
New engineering role for inference, model serving, kernels/CUDA/Triton, GPU/TPU performance, HPC and distributed-training infrastructure. Created because ~145 active jobs across ~50 companies were split between infrastructure_platform_engineer (~60) and ml_engineer (~35) with the rest scattered; the population is coherent and is the fastest-growing engineering specialism at AI infra companies. Populated by title-pattern move from infra/platform, ml_engineer, backend, applied_ai_engineer, database_systems, fullstack, software_engineer, research_engineer and member_of_technical_staff.
- Deployment StrategistSales & GTM
New sales_gtm role for Palantir-style customer-embedded strategists. 70+ active "Deployment Strategist" titles were sitting inside solutions_architect (670 jobs), where they were 19% of the role and structurally different work (outcome ownership, not architecture). Split out by title pattern.
- Applied AI ArchitectSales & GTM
New sales_gtm role for customer-facing applied-AI builders at model vendors. "Applied AI" titles (132 active) were scattered across 8 roles (solutions_architect 44, applied_ai_engineer 25, field_engineering_management 13, solutions_engineer 12, ml_engineer 8, client_partner 6...). Customer-facing population consolidated here; product-side stays in applied_ai_engineer, which was re-scoped to product-only.
- Data Center Program ManagerBusiness Operations
New operations role for data-centre / compute-capacity programme management (site selection, capacity delivery, DC launches, power projects). ~45 active jobs at 11 companies (Anthropic, OpenAI, Nebius, Nscale, CoreWeave, Crusoe, Cerebras...) were 18% of program_project_manager and a distinct population tied to the compute build-out.
- Mechanical & Thermal EngineerPhysical Systems
New physical_systems role. hardware_electrical_engineer (348 active, 157 distinct titles) was two populations: electrical/power (~100) and mechanical/thermal/structural/fluid (~105). Split by title pattern; hardware_electrical_engineer re-scoped to electrical.
- Billing, AR & CollectionsFinance
New finance role for billing operations, accounts receivable, credit and collections (order-to-cash back office). Flagged as a taxonomy gap by the June sweep (Credit & Collections Manager, no_role_fit). ~14 active jobs were split across revenue_accountant, accounts_payable_specialist, other_finance, other_operations and business_operations_manager.
- GTM EngineerSales & GTM
New sales_gtm role for engineers building GTM systems and growth tooling. "GTM Engineer" / "GTM Systems" / "Growth Engineer" titles (~40 active) were spread across revenue_operations, ai_agent_engineer, fullstack/frontend/software_engineer, business_applications_administrator, other_engineering and technical_program_manager. revenue_operations re-scoped to non-engineering.
- Litigation & Disputes CounselLegal & Compliance
New legal_compliance role for litigation, disputes, investigations and e-discovery. Flagged as a taxonomy gap by the June sweep (Litigation Counsel at Waymo, no_role_fit). Small population today (2 active, 9 all-time) but structurally distinct from commercial/general counsel; created so the classifier has a home for it.
- Prompt Engineer (retired)
Deprecated: 2 active jobs in 6 months, 6 ever; the predicted role never materialised as distinct work. Hidden; description marked DEPRECATED so the classifier stops using it. Remaining jobs reclassified individually.
- Content & Knowledge Specialist (retired)
Deprecated: 3 active jobs, all better served by content_and_social_media_manager / customer_enablement_specialist / technical_writer. Hidden; description marked DEPRECATED. Remaining jobs reclassified individually.
- EngineeringfunctionGTM Engineer boundary now points to gtm_engineer; added Inference & Performance Engineer mention.
- Sales & GTMfunctionAdded VERTICAL-PRODUCT GUARDRAIL: the exception must not pull a vertical AI company's in-house Legal/Finance/Marketing/Design/Product/Data/CS roles into Sales & GTM. Motivated by the Sept sweep backlog, where ~60 Harvey, DualEntry, EliseAI, Legora, Giga and Sierra in-house roles sat in other_sales_gtm at confidence 0.15-0.35.
- Engagement ManagerCustomer SupportTitle rule added: every "Engagement Manager/Director/Lead" title at a vendor routes here (customer_support), with named exceptions. Previously the identical title split 22/21 between engagement_manager and client_partner plus 14 more across solutions_architect, other_sales_gtm, other_operations and implementation_specialist.
- Solutions ArchitectSales & GTMRemoved Deployment Strategist and Applied AI Architect populations (→ deployment_strategist, applied_ai_architect); added routing-out notes; example_titles/keywords trimmed accordingly.
- Applied AI EngineerEngineeringRe-scoped to product-side only; customer-facing applied AI → applied_ai_architect; inference → inference_performance_engineer.
- Machine Learning EngineerEngineeringRemoved "Applied AI Engineer" from example_titles/keywords (was a misroute source); added routing to inference_performance_engineer, applied_ai_engineer and member_of_technical_staff.
- Infrastructure & Platform EngineerEngineeringAdded routing to inference_performance_engineer; clarified MTS-titled infra jobs belong here by content.
- Hardware & Electrical EngineerPhysical SystemsRe-scoped to electrical/power/PCB/RF; mechanical/thermal examples and keywords moved to mechanical_thermal_engineer.
- Program & Project ManagerBusiness OperationsAdded routing to data_center_program_manager; removed TPM keyword.
- Technical Program ManagerEngineeringAdded routing of data-centre/capacity TPMs to data_center_program_manager.
- Client PartnerSales & GTMAdded exclusions: Engagement Manager titles → engagement_manager; Applied AI Architect/Engineer → applied_ai_architect.
- Revenue & Sales OperationsSales & GTMRe-scoped to non-engineering; GTM Engineer / GTM Systems examples and keywords moved to gtm_engineer.
- Forward Deployed EngineerEngineeringRemoved GTM Engineer example; added routing to deployment_strategist, gtm_engineer, applied_ai_architect.
- Research EngineerResearch & ScienceAdded routing of kernels/inference infra to inference_performance_engineer and core training to member_of_technical_staff.
- Accounts Payable & Payroll SpecialistFinanceAdded routing of AR/billing/collections to billing_ar_collections.
- Revenue AccountantFinanceAdded routing of operational billing/AR/collections to billing_ar_collections.
- General & Corporate CounselLegal & ComplianceAdded routing of litigation/disputes to litigation_counsel.
- Model Training & Post-Training (MTS)Research & ScienceRedefined from a title bucket to a content role: "Model Training & Post-Training (MTS)". 218 active MTS-titled jobs were being routed by content into 8 roles while 75 sat here by title; the notes now state explicitly that the MTS title is not a signal and this role is for pre-/mid-/post-training, RL and training-data work only. Slug retained to preserve URLs and history.
