About the Company
Lovable is the software creation platform that empowers people to act on the problems closest to them. Since its launch in November 2024, over 60 million projects have been built on Lovable by solopreneurs, small business owners, and teams at companies like Adidas and Zendesk. We're building a generational company from Stockholm, with growing teams in London, Boston, New York, and San Francisco. Our team is small, talent-dense, and moving quickly, with a culture rooted in extreme ownership, high velocity, and low-ego collaboration.
TL;DR
We're seeking exceptional senior engineers and technical leaders for our Platform team, who own the infrastructure that powers Lovable's AI product and the developer experience that lets our engineering teams move at maximum velocity.
Responsibilities
- 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.
- Bring order and structure to our codebase; integrate or build application frameworks to support a growing engineering organization.
- Own and develop our observability stack, from code instrumentation through ingestion to presentation.
- Harden our infrastructure against failures, downtime, and slowdowns - ensuring it never becomes a bottleneck to growth.
- Plan and implement our network infrastructure and cloud strategy.
- Integrate tools for AI-driven development across the engineering organization.
- Identify and drive reliability improvement efforts across all engineering teams.
Requirements
- 10+ years in platform, infrastructure, or developer experience engineering, with a track record operating at senior engineering levels.
- Deep experience building and operating in one or more of: production infrastructure, platform engineering, or developer experience (observability, CI/CD, application frameworks, productivity tooling).
- Strong proficiency in at least one systems-oriented language (Go, Rust, C++, or similar), with a track record of designing high-throughput services at scale - and/or experience writing code and tools to support growing engineering orgs in scale-ups.
- Solid working knowledge of Docker, Kubernetes, and modern infrastructure practices; ideally with understanding that goes deeper than configuration - how schedulers, runtimes, and isolation boundaries actually work.
- You ship high-leverage systems fast and know when to make trade-offs between security, stability, and speed.
- You're comfortable navigating ambiguity and driving clarity at an organizational level, not just technically.
- You're based in Stockholm or ready to relocate - this is an on-site, 5-days-a-week role.
