We are looking for a highly motivated and high-potential Senior Staff Site Reliability Engineer (SRE) to join our team as a senior technical leader, driving transformational change and delivering significant business impact across WEX's platform ecosystem. This is a truly exciting moment to be part of the SRE organization at WEX. Our sophisticated platforms support a broad spectrum of customer businesses and generate vast, complex telemetry and operational data. Reliability, scalability, and efficiency are critical to unlocking the full potential of our services and enabling business and customer value at scale. As a Senior Staff SRE, you'll be at the forefront of defining and executing WEX's reliability engineering vision. You'll lead complex, cross-functional initiatives that elevate our observability, incident and problem management, automation, performance optimization, and capacity planning capabilities. You'll architect resilient systems, design proactive reliability strategies, and build the frameworks and tooling that power operational excellence across the company. Beyond hands-on technical contributions, you'll serve as a strategic thought partner to engineering, product, and platform leadership—setting direction, influencing architecture, and embedding SRE principles across our development lifecycle. You'll mentor engineers across levels, scale best practices, and act as a catalyst for a culture of reliability, continuous improvement, and innovation. We work with modern technologies, leverage AI and automation to drive smarter operations, and operate within an agile, product-centric engineering model. If you're a visionary technical leader passionate about building reliable, scalable systems—and you're excited to make a lasting impact while growing your career—this is a rare and powerful opportunity.
