Sr Software Engineer, Ruby on Rails

Company

Pay Pal has been revolutionizing commerce globally for more than 25 years. Creating innovative experiences that make moving money, selling, and shopping simple, personalized, and secure, Pay Pal empowers consumers and businesses in approximately 200 markets to join and thrive in the global economy.

We operate a global, two-sided network at scale that connects hundreds of millions of merchants and consumers. We help merchants and consumers connect, transact, and complete payments, whether online or in person. Pay Pal is more than a connection to third‑party payment networks. We provide proprietary payment solutions accepted by merchants that enable the completion of payments on our platform on behalf of our customers.

We offer our customers the flexibility to use their accounts to purchase and receive payments for goods and services, as well as the ability to transfer and withdraw funds. We enable consumers to exchange funds safely with merchants using a variety of funding sources, including bank accounts, Pay Pal or Venmo balances, credit products, debit cards, certain cryptocurrencies, or other stored value products such as gift cards and eligible credit card rewards.

Our Pay Pal, Venmo, and Xoom products also make it safer and simpler for friends and family to transfer funds to each other. We offer merchants an end‑to‑end payments solution that provides authorization and settlement capabilities, instant access to funds, and payouts. We also help merchants connect with customers, process exchanges and returns, and manage risk. We enable consumers to engage in cross‑border shopping and merchants to extend their global reach while reducing complexity.

Our beliefs guide our daily conduct. We live each day guided by our core values of Inclusion, Innovation, Collaboration, and Wellness. Together, we ensure we work as one global team with our customers at the center, and we take care of ourselves, each other, and our communities.
