Senior Product Manager

Turn new revenue opportunities into products construction companies pay for.

Your mission

Cosuno is the marketplace where construction companies run their tenders: general contractors invite subcontractors to bid, and subcontractors find and win new projects. More than €100 billion in bid volume has already been tendered on our platform.

We see several ways to grow from here, such as new modules for existing customers or customer segments we don't serve yet. As our Senior PM for Growth, you'll own one of these opportunities and you'll help choose the next. Next to that, you'll take care of the day-to-day product work in your area.

What you'll do

• Find the real problem. Talk to customers, many of whom aren't tech-savvy, dig into our data and work out who has the problem, how much it matters and what we need to build.
• Put AI to work. Construction still runs on a lot of manual work. You'll find where AI can replace it and turn that into products customers love.
• Test before you build. Prototype and run small experiments with real customers before Engineering commits, then ship with Design and Engineering.
• Bring it to market. Launch with Sales, Marketing and Customer Success, from positioning and pricing to enablement, and measure what it brings in.

After one year, you've taken your first opportunity to real customers, you're working on your second, and the new offerings bring in measurable revenue.

How we work

• Full ownership. You own your growth opportunity end to end, from the first customer conversation to the revenue it brings in. Design and Engineering build with you.
• Close to the customer. You'll talk to customers constantly.
• Fast and data-driven. We ship every two weeks, test ideas before we build them and judge every launch by its numbers.
• AI-first. We're an AI-first company. AI is at the core of our product, and we work with Claude Code and other AI tools every day. For every opportunity, your first question is: where can AI take manual work off our customers' hands?

What you bring

• 3–5 years as a product manager in B2B SaaS, and you want to stay hands-on
• You've taken a new revenue opportunity (a module, upsell, segment or market) from idea to a product customers pay for
• You've shipped AI features that customers actually use, and you use AI tools every day in your own work
• You work with numbers and experiments, and you change course when the data says so
• You explain complex things simply, to a site manager as well as to management
• German at C2 level and fluent English: our customers work in German, our engineering team in English
• Experience with two-sided marketplaces, or with construction or another industry that is just going digital.

Why us?

• Real impact: You own a growth opportunity, with short decision paths to our Head of Product, and you see the result in our numbers.
• A head start: Your first opportunity is prepared for you, so you can get going from day one.
• Competitive compensation: A salary above the market average.
• Work-life balance: Work fully remotely from anywhere in Europe, or from our office in Berlin Kreuzberg.
• Top-notch equipment: A new MacBook Pro.
• A great team: Regular company off-sites and team events.
• Job security: A permanent contract in a stable, well-funded company.
• Growth & feedback: An open feedback culture with regular 1:1s and development conversations.
