About commercetools

Real innovation starts with a strong foundation, and at commercetools, that comes from the perfect balance of our product and our people. Behind every leap forward is a collective of builders, explorers, doers, makers, and problem-solvers. The kind of people who not only pioneered a more flexible approach to commerce architecture but also shaped the culture of experimentation that approach unlocked. Together they are the engine of commerce innovation today. At commercetools, we power the next era of autonomous commerce for our customers. Whether it’s AI-driven solutions that help enterprises make smarter business decisions, bridging digital and physical shopping experiences, or enabling entirely new ways for industries to connect with their customers, we help the world’s most ambitious companies experiment, scale, and grow without limits. Here the best idea wins, not the loudest voice. You will have the tools, trust, and space to not only build the future of commerce, but to build your own.

Your Impact

As the Principal Engineer championing Resiliency, you’ll be the driving force behind how commercetools prepares for, responds to, and learns from operational incidents at scale. Our customers rely on us for mission-critical commerce infrastructure, including during their highest-stakes moments of the year, like Black Friday. You’ll own the discipline of resiliency end-to-end: mature incident management, strong operational visibility, data-driven process improvement, and organization-wide readiness for peak-traffic events.

• Standardize Incident Management: Build and champion intuitive, end-to-end processes for incident detection, response, communication, and postmortems across the company.
• Enhance System Visibility: Develop clear, real-time metrics, dashboards, and signals to track system health and incident trends.
• Drive Data-Backed Improvements: Use operational data to find process gaps, partnering with product engineering teams to fix them.
• Own Peak-Event Readiness: Scale and lead the organization-wide readiness program for massive traffic spikes like Black Friday.
• Lead Cross-Team Initiatives: Identify resilience gaps, collaborate with infrastructure/product teams on solutions, and turn ideas into concrete technical outcomes.
• Cross-Functional Collaboration: Partner closely with engineering leadership, Staff Engineers, and domain-specific Principal Engineers (Cloud, Security, API, Architecture, Performance).
• Foster Knowledge Sharing: Drive organizational communication, documentation, and training around resiliency and operational excellence.

This role is hybrid, with three days a week spent in our Berlin, London, Munich or Valencia office.
