Job description

GoCardless, a Mollie company, is a global leader in bank payments. Over 100,000 businesses, from start-ups to household names, use GoCardless to collect, manage and send bank payments through Direct Debit, real-time payments and open banking. With US$130bn+ processed annually across 30+ countries, we handle recurring and one-off payments without the chasing, stress, or expensive fees. Our end-to-end payment platform also features AI-powered solutions to improve payment success and reduce fraud, alongside connections to over 350 platforms businesses use everyday. We are headquartered in the UK, with teams and operations spanning North America, Europe and Asia-Pacific. For more information, please visit www.gocardless.com and follow us on LinkedIn @GoCardless. Mollie is the leading payments and financial services partner for business, rooted in Europe, with global reach.

The role

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.

Day-to-day will focus on:

• 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

What you’ll bring

• 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

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
