Migration Manager – SaaS B2B | Onboarding & Migration Client

As a Migration Manager, you will be the single thread running through every customer migration: from the very first conversation to post go-live stabilisation, you will be the customer's named point of contact and the internal orchestrator. This role goes well beyond a standard onboarding profile. You will drive the full migration cycle, coordinate Solution Engineers and the Onboarding team, and deliver onboarding directly on standard accounts. Your mission is to own the end-to-end migration of IDnow customers onto the TrustPlatform, managing customer relationships, internal teams, and risks, with rigour and autonomy.

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 processes

Requirements

• 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

• Access to mental health platform nilo including 1on1 sessions
• Access to Udemy training platform with unlimited content and certification
