About the Company

Cosuno - Revolutionizing construction through technology.

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.
