Anaplan Architect – Senior Model Builder

Role Overview

• Establish Anaplan as the single source of truth for headcount across FP&A, Workforce Planning, and operations teams.
• Enable scalable, repeatable headcount planning, forecasting, and in-year management processes.
• Define and champion reusable Anaplan standards (model design patterns, list structures, naming conventions, UX patterns) that can be applied across HubSpot’s Anaplan landscape to drive consistency and scale.
• Consolidate and streamline Anaplan data hubs and planning processes so HubSpot’s Anaplan environment operates as a unified, connected planning platform rather than a set of isolated models.
• Own the end-to-end architecture, design and ongoing optimization of the central Anaplan headcount model and related workforce planning use cases (annual planning, in-year forecasting, hiring plans, position management, and outlook reporting), using best-practice Anaplan design principles to keep the live model scalable, performant, and easy to use.
• Establish and maintain a single system of truth for headcount by centralizing headcount and position data in Anaplan and connecting it to downstream planning and reporting models (FP&A, Sales Ops, Customer Success, Talent Acquisition Management, etc).
• Design, build and manage integrations between Anaplan and core systems (e.g., Workday, Greenhouse, NetSuite, existing Anaplan models, and other data sources, partnering with Finance Transformation, Anaplan model builders, and tech teams to ensure robust, well-documented data flows.
• Partner with Strategic Workforce Planning, FP&A, and People teams to understand end-to-end headcount processes (plan-to-hire), define ideal-state workflows, and translate business requirements into intuitive Anaplan UX pages, modules, and processes.
• Implement strong data quality, control, and reconciliation practices for headcount and cost data flowing through Anaplan, in partnership with data and integration owners (e.g., ensuring clear ownership, validation checks, and error-handling SLAs across data pipelines).
• Define and contribute to Anaplan-wide standards, including model design patterns, list structures, naming conventions, performance tuning, access/security configuration, and documentation; coach more junior model builders and functional partners on best practices.
• Participate in roadmap buildout for company-wide goals and model-specific enhancements.
• Identify opportunities beyond headcount to expand connected planning capabilities proactively assessing adjacent planning domains (e.g., NNARR planning, capacity planning, productivity, scenario modeling, or other cross-functional use cases).

Requirements

• 4+ years of hands-on experience building and maintaining complex Anaplan models in production environments.
• Demonstrated experience acting as a lead or architect for Anaplan solutions, including schema design, module architecture, and UX configuration.
• Strong understanding of workforce planning processes (annual planning, in-year forecasting, position management, hiring plans) and their connection to financial planning and reporting.
• Experience designing and consolidating Anaplan models into a cohesive connected planning ecosystem.
• Proven ability to translate ambiguous business requirements into scalable technical designs, user stories, and documentation.
• Experience designing integrations between Anaplan and HRIS, ATS, ERP, or data platforms (e.g., Workday, Greenhouse, NetSuite), including source-to-target mapping and reconciliation.
• Strong analytical and problem-solving skills, with attention to detail and a focus on process simplification and automation.
• Excellent communication and collaboration skills, with experience facilitating working sessions across Finance, People, and Operations teams.
