ABOUT THE ROLE We're looking for a Senior Software Engineer (Backend/Infrastructure) for the VTEX Network team ,the core connective tissue of our cloud platform: CDN, Cloud Connectivity, Ingress, DNS, and Service Mesh. You'll take on one of our hardest engineering challenges: evolving our Service Mesh. Today VTEX runs a custom, highly performant router (built in .NET) that acts as our service mesh, processing millions of requests per second as the backbone for every VTEX application. Your mission is to help evolve this mission-critical infrastructure toward a market-standard stack (like Istio) with zero downtime and the reliability thousands of stores depend on. This sits at the deep intersection of software engineering and scalable infrastructure, and it rewards real care for performance, resilience, and system architecture. ABOUT THE TEAM The Cloud Network team ensures the reliability, scalability, and performance of the platform that powers thousands of stores worldwide. As part of a recent transformation, we're building a new generation of infrastructure systems: Service Mesh, networking, and compute layers. Our goal is a platform where infrastructure complexity is abstracted away, so engineers move faster without trading off reliability or performance. WHAT YOU WILL DO • Drive the architectural evolution from our custom routing layer to a modern, market-standard Service Mesh (e.g., Istio); • Design, build, and maintain network components that sustain millions of requests per second at very low latency; • Keep VTEX's core network services (Ingress, DNS, Service Mesh, CDN) continuously available and resilient for thousands of stores globally; • Apply deep service-design principles to build scalable, robust, maintainable backend services and infrastructure tooling; • Use AI as a daily multiplier (for development, refactoring legacy internals, testing, and documentation) while exercising judgment about where it does and doesn't belong in critical infrastructure; • Raise the team's bar: mentor other engineers, document for both technical and non-technical audiences, and take an active part in hiring.
