Mollie is the leading payments and financial services partner for business, rooted in Europe, with global reach.

A large share of our reach comes through partners: payment service providers, software platforms and ecosystems that offer bank payments to their own customers. As Partner Solutions Engineer, you’ll be the technical lead on those relationships, from the first conversation through to a live integration and beyond.

You’ll work alongside our Partnerships team to qualify opportunities, run technical discovery, design the integration and get the partner live. You’ll be the person a partner’s engineers trust when something misbehaves in the sandbox, and the person who can explain to their commercial team why a design choice matters.

• Lead technical discovery with prospective and existing partners and turn it into a clear solution design using our various partner APIs such as Embed & Connect
• Build and deliver demos and proofs of concept that show how bank payments work inside the partner’s product
• Guide partners through integration, testing and launch, including webhooks, failure handling and go-live readiness
• Work with Partnerships to qualify, shape and close partner opportunities
• Build the assets that make the next integration faster, e.g. guides, sample code, Postman collections and integration checklists
• Keep us ahead of how partners use our APIs with newer tooling, including MCP and agentic commerce

Essential:

• Experience as a pre-sales, post-sales or implementation engineer working directly with customers or partners
• Hands-on API experience: you’re comfortable in Postman, reading logs and debugging a failing request
• Working knowledge of OAuth, webhooks and common integration patterns
• Programming skills in at least one common language
• A solid understanding of how APIs and MCP servers work

A Real Advantage:

• Experience building integrations with payment service providers or platforms
• Knowledge of payments, eg. Direct Debit, open banking, cards and alternative payment methods
• Experience working with platforms or multi-tenant models
• Day-to-day use of AI tools in your own engineering work

• You’re a problem solver who likes getting stuck into the detail
• You’re curious and learn new systems quickly
• You like being consultative, asking good questions before proposing answers
• You get a kick out of helping partners grow and build something new
