## Description

Your Mission 
 Cosuno is a B2B marketplace connecting general contractors and subcontractors across the construction industry. As our Senior Lifecycle & Retention Manager, you'll build the growth engine that turns new users into active, paying and retained customers — and move us toward an AI-native, signal-driven system that decides what happens next on its own. You'll be one of the first to join the marketing lead in a lean marketing team: you'll shape how it operates as it scales, not just execute inside a fixed setup.
 What you’ll do 
 • You build the CRM programmes and lifecycle journeys that drive adoption and conversion — from first tender discovery to paid conversion for subcontractors, and early product adoption to repeat tendering for construction companies.
• Together with the Marketing Lead, you build an agentic, signal-driven system that turns behavioural data, call insights and enrichment signals into personalised next-best-action triggers — replacing static journeys with ones that decide what happens next on their own.
• You experiment and measure with A/B tests and holdout groups, so decisions are based on incremental impact, not campaign output.
• You scale what works into a repeatable system, not one-off campaigns.
• You connect journeys with Sales and Customer Success, handing off to a human touch when that's more effective than automation.
• You use CRM as a lever for marketplace liquidity — getting the right subcontractors onto the right tenders — and orchestrate email, in-app, transactional comms and marketplace recommendations as one journey with Prod
