Senior Software Engineer

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, you will dive deep into complex fintech projects, writing efficient, maintainable code, and solving challenging problems. You won't just be closing tickets; you will be thinking about how your code impacts a merchant's cash flow or a consumer's checkout experience.
