Our thesis is simple: acquire great firms, then make them materially better through shared technology and scale. The first part is working. The second part needs dedicated owners. This role is the 10x multiplier for our tech pods in each vertical. PX sits between our portfolio companies and our product engineering team, owning the full product lifecycle from onboarding through ongoing adoption. You'd turn our application capabilities into real, working workflows inside each firm - leveraging AI, automation, and vibe-coded utilities to build repeatable playbooks that scale across the portfolio without sacrificing quality. This is not a support role. It's a strategic operator role for someone who speaks professional services and product, and is excited about being accountable for making our portfolio companies genuinely successful with our products. What you'll own Your work breaks into two stages of the firm lifecycle: Stage 1: New firm onboarding Goal: Accelerate product onboarding time from months to weeks You drive and project manage the end-to-end product onboarding for each new portfolio company: - Product solutioning — map out firm workflows, identify bottlenecks, design + implement new workflows leveraging internal and 3rd party tools to help improve firm productivity. This might involve building new automations independently or working with the engineering teams to develop new application capabilities. - Data migration — scope what data needs to be migrated, work with engineers to execute, and validate clean data transfer from legacy systems to our application - Tooling consolidation — work with Corporate IT to setup firm Microsoft/Google instances, evaluate the existing firm's tech stack, and decide what tools to keep vs consolidate - Billing setup — configure billing infrastructure so firms can operate from day one - Initial product training — upskill the firm's employees from 0 to 1 to enable value-creation via our platform Goal: Measurement infrastructure live within 30 days of firm close You set up the measurement infrastructure from day one: - Define and instrument baseline product and business metrics (time per workflow, time in Multiplier vs. client court, etc.) - Build and manage reports and dashboards that track performance improvement over time - Create the data layer that helps articulate our platform is actually making firms more efficient (higher throughput, higher FCF) Stage 2: Ongoing engagement Once a firm is onboarded, you own the ongoing relationship and product experience: - Firm product cadence (goal: product adoption + alignment) — lead regular roadmap review sessions and product demo walkthroughs with firm operators and staff, keeping them informed on what's shipping, gathering live feedback, and building buy-in for new capabilities before they land - Product operations (goal: resolution speed + CSAT) — triage incoming requests and issues, prioritize ruthlessly, and manage the pipeline for tech pod consumption. You help ensure the engineering teams work on the right things. - Last-mile p
