Build with us
Since 2004, we've had one clear goal: to make payments and money management effortless for every business in Europe.
Today, more than 250,000 companies use Mollie to get paid, manage money and grow – with products designed to be simple, scalable, and dependable.
With 950+ Mollies across 14+ locations, we care deeply about autonomy and craft. So we work in small teams, with real ownership, and we trust you to make the right decisions.
We're building for the long term, so we provide the tools you need, processes you can rely on, and a balanced work environment to help you do work you're proud of.
Sound like your kind of place? Let's build together.
Your Impact
You'll own the post-sales integration phase for Mollie's largest and most complex deals, taking full responsibility from contract signature through go-live and the handover that follows. That means acting as the central point of contact for the merchant and every internal Mollie team involved, setting out the activities, owners, and timelines needed to get each implementation live.
You'll coordinate closely with sales, sales engineering, onboarding, compliance, product, and other teams to resolve issues as they come up, using your technical understanding to assess merchant problems, work through documentation, and route issues to the right place. You'll keep merchants, digital agencies, and internal stakeholders informed with regular updates, and you'll monitor progress against the agreed go-live date so you can act early when timelines are at risk.
This is a newly formed function that's now expanding into new markets. That means you'll have genuine influence over how the role and its processes take shape, working closely with a flat, collaborative team where good practice is shared regardless of hierarchy.
Responsibilities
- Own the post-sales integration phase for Mollie's largest and most complex deals, from handover through testing to go live

- Organize and track testing, raising issues and feedback as they surface
- Coordinate across sales, product, and engineering colleagues, as well as with merchants directly, to keep everyone aligned
- Keep agreed go-live dates on track, since delays mean missed revenue
- Maintain documentation and playbooks that make delivery predictable and scalable
Requirements
- At least 3 years of relevant experience in implementation, project management, onboarding, delivery, or a similar customer-facing role.
- Experience in payments, fintech, e-commerce is a plus
- Proven experience managing complex implementations from contract signature through go-live and handover.
- Solid understanding of APIs, integrations, and technical documentation, with the ability to investigate implementation issues and work with technical teams.
- Strong project and stakeholder management skills, including managing timelines, blockers, dependencies, and multiple internal and external stakeholders.
- Structured, proactive, and pragmatic approach, with strong ownership and the confidence to challenge when needed.
- Excellent communication skills in English
