Expert(e) Adyen Freelance

This freelance role offers the opportunity to make a measurable impact on payment performance across a portfolio of international SaaS products. You will take ownership of auditing, stabilizing, and optimizing Adyen integrations, with a strong focus on recurring and subscription-based payments. Working closely with payment, technology, and product teams, you will help improve authorization and renewal rates while strengthening fraud, risk, and dispute management. The mission combines technical expertise with strategic recommendations and hands-on implementation. You will operate with significant autonomy in a remote, multi-product environment where results are closely tracked. The assignment is designed for an experienced specialist who can become operational quickly and deliver tangible improvements from the first weeks.

• 5+ years of professional experience in payment-related roles, with confirmed to senior-level expertise.
• Strong hands-on experience integrating and optimizing Adyen in production environments, specifically for recurring or subscription-based payments; experience limited to one-off e-commerce transactions is not sufficient for this role.
• Advanced knowledge of Adyen APIs, Customer Area, and risk-management tools.
• Strong understanding of 3DS2/SCA, authorization-rate optimization, payment retries, account updater processes, and chargeback management.
• Experience with a billing orchestrator is highly valued, while knowledge of other payment service providers is a plus.
• Previous experience working with Adyen directly, as a solution or implementation engineer, or within a B2C SaaS subscription or marketplace environment is advantageous.
• Strong autonomy and ownership, with the ability to audit, prioritize, and deliver independently without extensive supervision.
• Excellent communication and teaching skills, with the ability to make complex payment topics accessible to product and technology teams.
• Strong analytical rigor and a results-oriented mindset focused on measurable business outcomes.
• Fluent French, as it is the primary working language.
• Professional fluency in English, which is the secondary working language and will be assessed during the recruitment process.
