About Groupon

Groupon is a marketplace where customers discover new experiences and services everyday and local businesses thrive. To date we have worked with over a million merchant partners worldwide, connecting over 16 million customers with deals across various categories. In a world often dominated by e-commerce giants, we stand out as one of the few platforms uniquely committed to helping local businesses succeed on a performance basis.

Groupon is on a radical journey to transform our business with relentless pursuit of results. Even with thousands of employees spread across multiple continents, we still maintain a culture that inspires innovation, rewards risk-taking and celebrates success. The impact here can be immediate due to our scale and the speed of our transformation. We're a "best of both worlds" kind of company. We're big enough to have the resources and scale, but small enough that a single person has a surprising amount of autonomy and can make a meaningful impact.

About the Role

Groupon is modernizing its global platform — and reliability is at the center of that transformation. We’re looking for a Principal Site Reliability Engineer to lead the evolution from reactive maintenance to predictive, AI-driven resilience. You’ll design intelligent, self-healing systems that prevent incidents before they happen, ensuring our customers enjoy fast, secure, and reliable experiences across millions of daily interactions.

• Build AIOps-based observability and auto-remediation pipelines.
• Apply predictive modeling to forecast failures before they impact users.
• Lead chaos, performance, and resilience testing programs.
• Map platform and service behavior to revenue impact and drive improved revenue resilience through better infrastructure performance.
• Mentor engineers and drive reliability standards across teams.
• Partner with platform, data, and product teams to ensure stability aligns with business goals.
• Support major incident response, incident review, and participate in on-call rotations.

What Success Looks Like

• 99.9%+ uptime sustained through predictive rather than reactive responses.
• Faster MTTR via automated detection and auto-remediation.
• Reliability insights used in leadership decisions.
