Software Engineer - Content Management System

About EveryPay EveryPay is the digital financial infrastructure powering the Skroutz Group. We don't just process transactions, we build the product experiences that enable millions of consumers to pay how they want and thousands of merchants to manage their wealth. As the fintech arm of Greece's largest marketplace, we bridge the gap between complex global banking rails (Visa, Mastercard, AMEX) and seamless user experiences. The Role & Our Mission At EveryPay, we are currently looking for a Software Engineer to join our team. Our engineering team's mission is to ensure EveryPay's backend systems are robust, secure, and scalable. We focus on building the product experiences that define modern e-commerce, from supporting consumer and merchant wallets to integrating Alternative Payment Methods (APMs) and solving the complex orchestration of multi-vendor marketplace checkouts. We are dedicated to maintaining a healthy codebase. Our team actively works to minimize technical debt and adopt modern tools that make developers' lives easier. Beyond standard upgrades, we are also incorporating practical AI solutions to speed up internal workflows, tune system performance, and keep our platform ahead of the curve. You won't be closing tickets in a queue. You'll be thinking about how your code impacts a merchant's cash flow, a consumer's checkout, or the integrity of a financial reconciliation. This is a role for engineers who are comfortable with ambiguity, care about correctness, and want to grow into a broader technical voice within the team. What You Will Do As a Software Engineer at EveryPay, you will focus on building and evolving the plugins and integrations that connect our payment platform with the ecommerce systems merchants rely on every day.

You will not just be developing plugin features or fixing integration issues. You will be thinking about how EveryPay fits into a merchant’s checkout flow, how payment states are handled across different platforms, and how your code impacts a consumer’s payment experience from checkout to confirmation.. In this role, you will: Design, build, and maintain CMS payment plugins and integrations for platforms such as WooCommerce, Magento, PrestaShop, OpenCart, or similar ecosystems Write modern PHP using strict types, typed properties, OOP principles, and PSR standards Work on merchant-facing payment flows, including checkout, redirects, callbacks, webhooks, refunds, transaction status updates, and error handling Ensure plugins and integrations are secure, maintainable, well-documented, and easy for merchants or partners to install and operate Identify opportunities to improve code quality, architecture, performance, observability, and developer experience Troubleshoot production issues related to merchant integrations, CMS environments,…
