Senior Backend Engineer-Cloud Modernization Role summary Israel Hybrid Full-time The Modernization Team mandate is to identify and solve the deepest, most systemic architectural challenges in the platform problems that are too strategic and cross-cutting for any single product team to own, yet too impactful to leave unresolved. We are not a feature team. We do not own a single service or product surface. Instead, we operate as a platform-level force multiplier: we take on the hardest problems, build shared solutions and tooling, and enable every product team at Payoneer to move faster and more safely. This is a brand-new team being built from the ground up. You will have an outsized opportunity to shape how we work, what we prioritize, and the engineering culture we create together. What you’ll do As a Senior Software Engineer on the Modernization Team, you will tackle the deepest, most systemic architectural challenges in Payoneer’s platform owning end-to-end migrations, building shared infrastructure, and creating the tooling that enables every product team to move faster and more safely. The Modernization Team operates with a native agentic mindset this is not an add-on or an experiment; it is core to how we build. We apply AI-assisted development across every phase of our work: automated code generation, AI-driven migration scripts, intelligent test generation, code review, and documentation. Our goal is not just to write code faster it is to build tooling that multiplies the output of every engineer working on modernization challenges.
