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 Product. - You support growth programmes such as referrals — from design through CRM execution. ## What You Bring - You've owned CRM, lifecycle, retention or growth programmes and can show the commercial impact they created — ideally in B2B SaaS or a two-sided business model. - You've directly influenced conversion, activation or retention metrics and are confident with data and experimentation. - You're genuinely AI-native: proven experience building AI-driven automation or agentic CRM systems, not just using AI to write copy faster. - You write and run SQL queries independently. - You go from data → insight → idea → implementation → result without needing someone else to define every step, and you like solving ambiguous problems and building from scratch. - You work effectively across Product, Sales, Customer Success and Engineering, and care more about measurable business impact than campaign output. - A plus: hands-on experience with ActiveCampaign and Salesforce (or comparable CRM tools). - Fluent in written and spoken German and English. ## Your Benefits - Room to shape and grow: One of the first marketing hires — real ownership of lifecycle and CRM, with plenty of space to make an impact. - AI at the core: Our product uses AI to analyze millions of price data points and help construction companies bid better — and we invest in it just as much internally. You'll build with the latest tools and move fast, not wait for approval. - Competitive compensation: Salary above market average, permanent contract in a stable, well-funded company. - Work-life balance: Fully remote or from our office in Berlin Kreuzberg, flexible hours. - Top-notch equipment: A new MacBook Pro. - A great team: Open, international, with regular off-sites and team events. - Growth & feedback: Open feedback culture with regular 1:1s and development conversations. ## About us Cosuno – Revolutionizing construction through technology.
