About the Company
Cosuno - Revolutionizing construction through technology. We are Cosuno - a fast-growing tech startup that is making the construction industry more efficient and transparent with our digital platform for tenders and procurement processes. Our goal: to solve the most complex challenges in the industry with innovation and simplicity. Join us - Build the future of construction.
Responsibilities
- ● 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.
