Staff / Principal Software Engineer, Security

TL;DR:We're looking for an exceptional senior engineer and technical leader for the security team to help make Lovable the most secure AI-powered software creation platform on the planet. 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 - 10+ years of engineering experience shipping production-grade products at high velocity, with a track record operating at senior engineering levels. - Deep, fluent command of React/TypeScript on the frontend and Golang on the backend. - Experience in one or more of: product security features (audit flows, compliance tooling, scanner interfaces), or code security and static analysis (SAST, linters, vulnerability scanners, or similar). - Solid understanding of systems design, performance tradeoffs, and scalable architecture. - Strong product sense - you can take something complex and make it feel simple and actionable for the user. - Familiarity with AI/LLM-powered tooling, or a background that involved dense algorithmic or systems work. - You're comfortable navigating ambiguity and driving clarity at an organisational level, not just technically. - 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:Build the security features and systems that make Lovable the most trusted AI software creation platform in the world. - Build security product features end-to-end - audit flows, security scanner UI, compliance tooling, design and implement static analysis and more. - Integrate AI/LLM capabilities into security workflows to detect, explain, and remediate vulnerabilities. - Ship across the full stack as part of a small, self-sufficient team, owning your work from the first commit to production. - Advocate for secure coding practices, conduct security-focused code reviews, and raise the bar across the engineering org. - Influence our technical direction and product strategy with a security-first mindset. OUR TECH STACK - Frontend:React and Typescript. - Backend:Golang and Rust. - Cloud:Cloudflare, GCP, AWS, multiple LLM providers. - DevOps & Tooling:GitHub Actions, Grafana, OTEL, infra-as-code (Terraform). - Data:Clickhouse, Firestore, Spanner, BigQuery.
