Job Description

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.

Job Responsibility

  • 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

Requirements

  • 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.

Nice to have

  • 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)

  • Cross-Platform Systems Mastery: Proven track record of architecting and shipping production-quality software for multiple operating systems (Windows, macOS, Linux) with a deep understanding of OS internals, networking stacks (L3-L7), and system performance tuning. Expertise in C/C++, Rust, or Go (Golang) for high-performance client development is required
  • Endpoint Security & Resilience: Deep authoritative knowledge of endpoint security mechanisms (e.g., integrity checks, sandboxing, driver development) and the ability to design agents that are resilient to tampering while maintaining a minimal security posture
  • Data Acquisition Pipeline Innovation: Experience building robust, secure, and resource-efficient data collection and buffering mechanisms within an agent, utilizing technologies for local data persistence and secure transfer
  • Security & Networking Visionary: Deep understanding of Zero Trust architecture principles applied at the endpoint, L3-L7 networking interception, and advanced encryption standards to ensure the ADEM Agent remains the most secure platform in the industry
  • Open Source & Community: A history of contributing to open-source projects (e.g., related to system monitoring, networking drivers) or speaking at industry conferences is highly desirable
  • Education: BS/MS/PhD in Computer Science or a related technical field, or equivalent high-level professional experience
