What you'll do

  • Own business-critical go-to-market projects across Enterprise Sales, Revenue Operations and Customer Success.
  • Identify inefficiencies in funnels, develop data-driven solutions and scale the revenue engine (pricing strategies, new market segments, sales cycle optimization).
  • Act as the link between commercial teams and Product/Tech, breaking down silos so everyone pulls together to exceed OKRs.
  • Relieve the founding team and CRO of day-to-day operations, prepare board meetings and independently make preliminary C-level decisions.

What we're looking for

  • 2-3+ years of experience from a leading strategy consultancy, or comparable strategic role in a high-growth B2B SaaS environment.
  • Strong affinity for B2B software metrics (ARR, CAC, LTV, Churn).
  • Data-driven decision making and mastery of financial/commercial modeling.
  • Precise communication and confidence at C-level and in board contexts.
  • Business-fluent German (native level) and excellent English.

Nice to have

  • Ideally already accompanied projects in GTM strategy, sales excellence or pricing.

Benefits

  • Direct, measurable influence on the company's success and valuation.
  • The CoS role is designed as a springboard to senior leadership roles (e.g. VP, Head of) within Cosuno.
  • Work from the modern office in Berlin-Friedrichshain or use the hybrid model.
  • Permanent contract, state-of-the-art equipment and regular team events.
  • Base salary €90K – €120K, plus equity and bonus.
