we are looking for a Team Lead R&D, Modernization, AI.
What youll do:
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.
It is not a feature team. You do not own a single service or product surface. Instead, the team operates as a platform-level force multiplier: it takes on the hardest problems, build shared solutions and tooling, and enable every product team at Payoneer to move faster and more safely. You will lead the full cycle from the discovery, design, building, and validating solutions, unblocking critical initiatives, and setting technical direction that other teams can confidently adopt.
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.

we are looking for a Team Lead R&D, Pricing & Packaging.
As an R&D Team Leader in the Pricing & Packaging R&D crew, youll be a key contributor to designing and building our monetization platform - pricing and packaging engines that drive the core business model of our payments platform. Youll own complex features end to end, influence architecture and standards, mentor your team members, and help shape how we design, build, deploy, and operate services in AWS. This is a hands-on senior role with significant impact and room to lead technical changes.
What youll do:
Collaborate closely with Product, Design/UX, DevOps, and other R&D teams
Lead an autonomous team of software engineers who are working closely with product management for achieving business goals
Put special focus on developing the team
Provide technical authority to your team by demonstrating a hands-on leadership style
Be responsible for the overall design, development, architecture, code quality, and production environment deployment of your team

we are looking for a Team Manager - Chargebacks & Payment Disputes.
What You'll Do:

Oversee team capacity, priorities, and service delivery to ensure execution aligns with business objectives.
Maintain and improve dispute management processes, policies, and controls across card payments, ACH debit, and other payment methods.
Manage relationships with banks, payment providers, customers, and external vendors, including their operational and risk teams.
Partner with Risk, Compliance, Reconciliation, Business, Product, and Customer Care on investigations and dispute resolution.
Lead process improvement, automation, and optimization initiatives to boost efficiency and reduce risk.
Own team performance across quantitative metrics (productivity, recovery rates, backlog, SLAs) and qualitative metrics (accuracy, compliance, audit readiness).
Use operational reports and data analysis to identify trends, risks, and opportunities for improvement.
