Customer Success Manager

Czech / Prague, Brno

B2B Contractor

TL;DR

We’re making HR superhuman with AI – need a customer success champion who turns clients into revenue-generating advocates, not just happy users.

The Mission: Own the long-term commercial success of your client portfolio. Act as a Strategic Partner to HR leaders and executives, drive measurable business value, maximize product adoption across all modules, and turn existing accounts into expansion revenue engines. This is a growth and revenue role — not support.
The Package: €3,200–3,600/month on contract + performance bonus, all the tools/hardware you need
The Challenge: Scale a high-performing, growth-driven Customer Success engine across multiple markets while consistently achieving 100%+ Net Revenue Retention through proactive retention, expansion, and executive-level relationship management.
The Fit: Smart and proven customer success professional with B2B SaaS experience who understands that customer success = revenue success

Drive portfolio growth (45% of your role). Identify expansion opportunities — new countries, module upgrades, plan transitions — and manage them through your own pipeline in CRM. You’ll run value-based conversations with clients, connect Sloneek features to their emerging HR challenges, and close upsells without waiting for Sales to initiate. You own the deal from discovery to close.

Own retention and strategic account management (30%). Lead QBRs and EBRs with C-suite contacts. Maintain documented Success Plans for top accounts. Forecast renewal risk 60–90 days in advance and execute mitigation plays before risk becomes churn.

Maximize adoption and build advocacy (15%). Act as a change management consultant when clients grow, merge, or restructure. Systematically turn happy clients into case studies, referrals, and G2 reviews.

Be the Voice of Customer internally (10%). Translate “I wish it did this” into prioritized business cases for Product. Maintain accurate Health Scores across your portfolio. Ensure no internal stakeholder is ever surprised by an account’s health or renewal outcome.

✅ 3+ years B2B SaaS CSM (Or in a similar role like Key Account Manager) with documented commercial ownership — NRR, GRR, expansion revenue, not just account management

✅ Proven upsell/expansion track record — you can walk us through specific deals you personally drove

✅ Executive-level experience — you’ve led QBRs or EBRs with CHROs or CEOs and owned the agenda

✅ Data-driven — you open your usage dashboard proactively, not when something breaks

✅ Assertive communicator — you push back when clients need a better solution, and you deliver hard news when necessary

✅ Fluent Polish + Czech/Slovak. English at B2/C1.

This Role Is NOT For You If…

You think CS is fundamentally a support function
You can’t give specific numbers when asked about your portfolio (ARR, NRR, account count)
Your renewals are handled 30 days before the date — not 60-90
You agree with everything clients say without product advocacy
You’ve never owned an executive-level business review end-to-end
You need Sales to initiate every expansion conversation

Cooperation: B2B contract

Fix: €3,200–3,600/month (based on experience and track record)

Provisions: €800/month, no cap

Benefits:

MacBook
professional development support
Co-working space allowance (Prague, Brno, Bratislava — and we’ll sort other cities too)
Mental health support

Culture: No bullshit. Remote-first. High autonomy grounded in real accountability. A team that moves fast and genuinely believes in what it’s building.

Still here? Good. Send us your CV and one short example of an expansion or upsell you personally drove — what happened, what you did, what the outcome was. Three to five sentences is enough. No cover letter needed. Show us the work, not the pitch.
