Do you fit?
2–5 years in Customer Success, Account Management, Forward Deployment Engineer or a technical client-facing SaaS/B2B role
Ideally a strong technical understanding — comfortable understanding API documentation and error logs to troubleshoot customer setup issues independently
Experience with tools like n8n, make.com, codex or similar
An affinity for tech / AI products is a real plus
Native or C2 Polish, strong English skills
Structured, autonomous, and results-driven
You build trust with customers easily — by phone, video, and in person
You take initiative, test, iterate — and you don't wait to be told what to do
Comfortable with a CRM (ideally HubSpot) and a data-driven approach to customer success
What you'll own
Own a portfolio of Polish SMB customers across their entire lifecycle with fonio
Spend most of your time in calls and meetings with customers — building relationships, surfacing value, and keeping them engaged
Run regular check-ins and trigger proactive calls based on usage signals (low engagement, expansion opportunities, setup friction, etc.)
Work with a ready-made pipeline and clear playbooks — with room to test your own initiatives and ideas to make them better
Maximize the value generated from each customer in your portfolio
Support customers in setting up their AI assistant and coordinate appointments with our developers for more complex setups
Own the churn within your cohort — spot risks early and act on them
Work autonomously in HubSpot to manage your activity
