TL;DR: We’re looking for an exceptional software engineer with a systems mindset to build and evolve the core infrastructure that can support the massive scale of the AI-native future. You will design, ship, and own critical and bespoke services and systems that power Lovable and making sure they're fast, reliable, and ready for whatever scale throws at them. WHY LOVABLE? Lovable is the software creation platform that gives people the power to act on the problems closest to them. For decades, turning an idea into software required so much capital, technical fluency, and time that many ideas never came to life. Lovable is the counterargument: a platform for all people with ideas, ambition, and problems worth solving. From solopreneurs to small business owners to teams at companies like Adidas and Zendesk, people have built over 60 million projects on Lovable since its launch in November 2024. And we’re just getting started. 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. We look for people who care deeply, ship fast, and are eager to make a dent in the world. Lovable is one of TIME’s 100 Most Influential Companies and has been recognized on the Forbes AI 50 and CNBC Disruptor 50, reflecting our momentum as one of Europe’s fastest-growing AI companies and one of the most ambitious places to build in this next era of software. 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: - Firecracker-based runtime environment for running agentic workloads. - Block-level storage systems for checkpointing and resumption of Sandboxes. - 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: - Backend: Golang and Rust. - Cloud: Cloudflare, GCP, AWS. - Data: Clickhouse, Firestore, Spanner, FoundationDB. - DevOps & Tooling: CI/CD pipelines, OTEL, Kubernetes, Terraform. And always on the lookout for what's next!
