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. 

    Who You Are 

    • 6+ years of experience in backend engineering in Node.js with strong fundamentals and production experience. 
    • Solid experience and understanding of distributed systems: messaging, caching, microservice communication patterns, and failure modes. 
    • Experience with AWS cloud infrastructure comfortable with the ecosystem even if not expert level in every service. 
    • Ability to own complex technical work end to end, from design through production. 
    • Hands-on experience with AI-assisted development tools (GitHub Copilot, Claude, Cursor, or equivalent) as a day-to-day engineering practice not a nice-to-have. 
    • Proven track record of driving architectural decisions with cross-team impact you have moved systems forward, not just improved them incrementally. 
    • Experience with large-scale migration programs: decomposing monoliths, rearchitecting data layers, or migrating messaging infrastructure in production environments. 
    • Strong communication skills; comfortable working across team boundaries. 

    Nice to have: 

    • .NET background, especially if you have migrated services from .NET to a modern stack. 
    • Experience building or operating shared platform infrastructure consumed by multiple teams. 
    • Familiarity with event-driven architecture patterns: outbox pattern, saga pattern.
