Athens, Attica, Greece Wonderful Full time €90,000 - €120,000 per year

At Wonderful, we're pioneering the future of Agentic AI – building AI agents that don't just chat, but act. Our platform powers enterprise-grade customer service and outbound sales across niche European languages and markets where no competitor even exists. Backed by $34M pre-seed funding from top-tier investors (Index, Bessemer), we're scaling fast: 80 people today, on track to 200+ across 20 countries. This is your chance to be part of the team writing the playbook for a brand-new category.

Role Overview:

We're looking for a 
Head of Customer Success & Program Delivery
 to own how our AI agents go live with enterprise clients — from idea to production. You'll bridge technical execution with client strategy, making sure every implementation lands on time, on scope, and delivers real business impact.

This role is half operator, half leader: you'll manage hands-on delivery of complex programs while building and scaling a high-performing client-facing team. If you thrive in the space between tech, people, and process — this is where you'll feel at home. You will:

  • Own end-to-end delivery of AI agent implementations for enterprise clients — from translating needs into timelines and deliverables to ensuring every launch happens on time and at quality.
  • Lead large, multi-stakeholder implementations — run cross-functional meetings, own the Gantt (milestones, dependencies, owners), and keep everyone aligned and accountable.
  • Guide clients through the full lifecycle — onboarding, adoption, renewals, and expansion — driving long-term impact, not just initial delivery.
  • Build and nurture strong relationships with enterprise customers — manage expectations, create alignment, and become their trusted partner in AI transformation.
  • Drive both leadership and execution — directly manage programs while establishing and scaling the local Client Success, Implementation, and Program Management functions.
  • Act as the primary point of contact for strategic accounts — ensure collaboration runs smoothly and issues are resolved before they escalate.
  • Take a hands-on role in delivery — oversee configuration, testing, optimization, and integrations to make sure agents perform flawlessly in production.
  • Manage risk, handle escalations, and remove blockers to keep programs on track and clients confident.

Requirements:

  • 5+ years in Program Management, Technical Project Management, or Technical Customer Success within enterprise SaaS, AI, or related tech environments.
  • Proven record of 
    hands-on
     delivery in complex, technical enterprise programs - not just coordination, but execution.
  • 2+ years in leadership roles, with experience hiring, managing, and scaling Program or Customer Success teams.
  • Experience building new functions or operations in growth-stage companies or new markets.
  • Excellent English (written and spoken) plus fluency in at least one local language.
  • Strong technical acumen - you're comfortable around APIs, cloud infrastructure, and enterprise IT integrations.
  • Outstanding communication, stakeholder management, and executive presence - you know how to hold the room.
  • Outcome-driven and highly independent, equally confident rolling up your sleeves or zooming out to shape long-term strategy.

Why Wonderful?:

  • A seat at the table as we build a new AI category from the ground up.
  • The energy of an early-stage scale-up + the stability of world-class investors.
  • Ownership, autonomy, and impact that you just won't find at corporate giants.
  • A team of ambitious builders who balance urgency with a strong sense of vibe.
