Software Engineer, Platform (Infrastructure)

TL;DR We’re looking for an exceptional software engineer with a systems mindset to build and evolve the core software behind the future of AI software engineering. You will design, ship, and own critical services and systems that power Lovable - making sure they're fast, reliable, and ready for whatever scale throws at them. WHY LOVABLE? Lovable lets anyone and everyone build software with any language. From solopreneurs to Fortune 100 teams, millions of people use Lovable to transform raw ideas into real products - fast. We are at the forefront of a foundational shift in software creation, which means you have an unprecedented opportunity to change the way the digital world works. Lovable-built applications and websites are visited hundreds of millions of times a month, and our enterprise footprint is compounding fast. And we’re just getting started. We’re a small, talent-dense team building a generation-defining company from Stockholm. We value extreme ownership, high velocity, and low-ego collaboration. We seek out people who care deeply, ship fast, and are eager to make a dent in the world. WHAT WE’RE LOOKING FOR - Deep experience building and operating production infrastructure as a Software Engineer, Systems Engineer, Site Reliability Engineer or similar. - You write clean, performant code and understand what happens all the way down - from the API layer to the runtime. - Familiarity with container orchestration and sandboxing at a level deeper than configuration. You understand how schedulers, runtimes, and isolation boundaries actually work, not just how to deploy on top of them. - Strong proficiency in at least one systems-oriented language (Go, Rust, C++, or similar) - You have a track record of designing services that handle high throughput and unpredictable load at a global tech company or scale-up. - You’re comfortable navigating ambiguity and solving problems as they arise. - You care about security, stability, and speed and know when to make trade-offs between them. - You’re based in Stockholm or ready to relocate - this is an on-site, 5-days-a-week role. WHAT YOU’LL DO In one sentence: Design, build and own the systems that makes AI engineering work for everyone. - Design, build and maintain the systems that enable our AI product, such as: - Gvisor-based runtime environment for running agentic workloads. - A high-throughput sandbox scheduler across multiple cloud providers, built on deep understanding of the orchestration layer rather than off-the-shelf abstractions. - Harden our infrastructure against failures, downtime, and slowdowns. - Support our growth by making sure that our infrastructure never becomes a bottleneck. - Plan and implement our network infrastructure and cloud strategy. - Identify and drive reliability improvement efforts across all engineering teams. OUR TECH STACK We're building with tools that both humans and AI love. Lovable software engineers are capable of working across the whole stack. Examples of tech in our stack include: - Frontend: React and Typescript. - Backend: Golang and Rust. - Cloud: Cloudflare, GCP, AWS, Modal. - Data: Clickhouse, Firestore, Spanner, BigQuery. - DevOps & Tooling: CI/CD pipelines, OTEL, Kubernetes, Terraform. And always on the lookout for what's next!
