• Build and maintain a repeatable integration playbook.
• Conduct rapid business diagnostics of acquired companies (people, processes, tools, performance).
• Coordinate cross‑functional workstreams across Operations, Revenue Management, Tech, Finance, and People.
• Identify improvement levers and synergy opportunities, and drive them to execution.
• Plug into acquired companies’ PMS and operational systems; design and execute data migrations into Arbio’s stack.
• Partner with Engineering to scope and prioritize technical integration work, owning the non‑engineering side end‑to‑end.
• Manage migration and harmonization of tools, systems, and processes into Arbio’s stack.
• Lead change management and integration of acquired teams into Arbio’s culture and ways of working.
• Track integration KPIs and report progress to the COO and leadership.
