We enable consumers to exchange funds more safely with merchants using a variety of funding sources, which may include a bank account, a PayPal or Venmo account balance, PayPal and Venmo branded credit products, a credit card, a debit card, certain cryptocurrencies, or other stored value products such as gift cards, and eligible credit card rewards. Our PayPal, 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, as well as instant access to funds and payouts. We also help merchants connect with their 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 the complexity and friction involved in enabling cross-border trade. Our beliefs are the foundation for how we conduct business every day. We live each day guided by our core values of Inclusion, Innovation, Collaboration, and Wellness.

You will define and drive the technical architecture strategy across PayPal’s Promotions Platform ensuring engineering teams build a cohesive, scalable, and resilient platform vision. Meet our team: PayPal’s Promotions Platform powers rewards and incentive experiences across the company’s three-sided network—connecting merchants, consumers, and PayPal's commerce ecosystem through offers, incentives, loyalty programs, and targeted campaigns. Our platform serves as foundational infrastructure for products including PayPal+, Venmo Rewards, merchant-funded offers, and large-scale promotional campaigns. We operate at the intersection of consumer experience, financial services, and distributed systems—processing millions of transactions, campaign evaluations, and reward events daily across global markets. Your Way to Impact: As Principal Engineer, you will be the technical authority for the Promotions Platform, defining the long-term architectural strategy and ensuring that our engineering teams are aligned on shared standards, domain boundaries, and platform evolution. You will translate business direction into durable technical decisions, reduce systemic risk through proactive platform governance, and elevate engineering quality across the organization. You will partner closely with stakeholders across roles and organizations to understand the business requirements and ensure the platform is built with intention, while maintaining its reliability and compliance required by a leading financial services company. Your work will directly accelerate PayPal's ability to launch new markets, onboard new reward partners, and deliver differentiated consumer loyalty experiences. Expectations: • Define and own the platform architecture roadmap: Establish and maintain the technical vision for the Promotions Platform, domain boundaries, ownership models, integration contracts, and API design. • Lead cross-team architectural governance: Drive architectural decision-making across five engineering teams, facilitating alignment on shared infrastructure, preventing domain boundary drift, and establishing clear patterns for campaign lifecycle. • Partner on platform-as-product strategy: Work alongside Technical Directors and Product leadership to define platform capabilities, engagement models, and intake processes that position the Promotions Platform as a scalable internal product serving multiple business lines. • Establish engineering standards and resilience frameworks: Define and enforce standards for observability, campaign governance, testing, and incident prevention—translating lessons from past operational incidents into durable systemic improvements. • Influence cross-organizational technical strategy: Represent the Promotions Platform in company-wide architectural forums, advocating for platform needs while ensuring alignment with PayPal's broader technical ecosystem including risk, compliance, and developer productivity platforms. • Drive architecture remediation and modernization: Define and execute a cohesive architecture remediation strategy that systematically decouples legacy systems, reduces fragmentation across heterogeneous infrastructure stacks, and moves the platform toward a unified, interoperable technology landscape. • Reduce friction in platform adoption: Lower the barrier to entry for engineering teams and partners consuming Promotions Platform capabilities by improving developer experience, standardizing integration patterns, and providing clear self-service tooling, documentation, and engagement models. Measure and continuously improve the time-to-integrate for new consumers of the platform, ensuring adoption is driven by the quality of the platform rather than heroic tribal knowledge. • Mentor and grow technical talent: Serve as a technical role model and coach for staff and senior engineers across the organization, elevating the overall architectural thinking and system design capabilities of the team.
