As an Customer Implementation Manager – SaaS B2B Migration Specialist (f/m/d) , you are the single thread running through every customer migration: from the very first conversation to post go-live stabilisation, you are the customer's named point of contact and the internal orchestrator.

This role goes well beyond a standard onboarding profile. You drive the full migration cycle, coordinate Solution Engineers and the Onboarding team, and deliver onboarding directly on standard accounts.

Key Responsibilities

• Own each migration end-to-end : project plan, milestones, risk management, weekly status reporting
• Act as the single named contact for the customer, from kick-off through to CSM handover
• Coordinate internal teams (Solution Engineers, Onboarding) on complex migrations: multi-product, multi-country, regulatory constraints
• Deliver onboarding autonomously on standard accounts: integration guidance, testing, go-live validation, hypercare
• Anticipate and escalate blockers before they impact the customer or the timeline
• Build migration playbooks to continuously improve our processes

Preferred Experience

• 3 to 5+ years of experience in a Post-Sales role in a B2B SaaS environment: Customer Success Manager, Implementation Manager, Technical Account Manager, Onboarding Project Manager, or equivalent
• Proven track record managing complex migration or implementation projects involving multiple internal teams
• Comfortable working with clients in regulated industries : Banking, FinTech, Insurance, Telco
• Sufficient technical understanding to read an architecture, challenge a solution design, and spot integration risks — without being a developer
• Transversal leadership : ability to mobilise teams without hierarchical authority
• French — fluent, required · English — professional level, required

Nice to Have

• Exposure to digital identity, KYC/AML, or eIDAS
• Familiarity with REST API integration environments
