Staff / Principal Software Engineer, Platform

Lovable Lovable · Coding AI · Stockholm, Sweden · Engineering

Staff/Principal Software Engineer for an AI Platform team, focusing on infrastructure and developer experience to power AI products and agentic workloads. Responsibilities include designing and building core systems, observability, network infrastructure, and integrating AI development tools. Requires 10+ years of experience in platform/infrastructure engineering with strong systems programming skills.

What you'd actually do

  1. Design, build and maintain the core systems that enable our AI product, including a gVisor-based runtime for agentic workloads and a high-throughput sandbox scheduler across multiple cloud providers.
  2. Bring order and structure to our codebase; integrate or build application frameworks to support a growing engineering organisation.
  3. Own and develop our observability stack, from code instrumentation through ingestion to presentation.
  4. Harden our infrastructure against failures, downtime, and slowdowns — ensuring it never becomes a bottleneck to growth.
  5. Plan and implement our network infrastructure and cloud strategy.
