What we're looking for: We are looking for a Senior Platform Engineer to join a team focused on the core foundations of our platform. In this role, you won't just be building features, you'll design and evolve the high-scale systems, shared frameworks, and architectural abstractions that enable our entire engineering organization to scale securely and efficiently. This is a "multiplier" role: your work will directly impact the performance, reliability, and velocity of every developer at Linx. This is a hands-on software engineering role focused on application and platform infrastructure. You'll spend your time designing and building backend services, developer-facing frameworks, shared libraries, SDKs, and core platform capabilities that other engineers build upon. While you'll work on foundational systems, this is not a DevOps, SRE, or cloud infrastructure role. The primary focus is software design and development, not operating infrastructure, managing CI/CD pipelines, or administering Kubernetes clusters.
