Fullstack Product Engineer
Lovable Labs Sweden AB · Stockholm · Tills vidare · Deadline 2026-10-30
Lovable Labs Sweden AB is seeking a **Fullstack Product Engineer** based in Stockholm to build software that allows users to create products using plain English. Working across the company’s entire stack, the engineer will implement and maintain features across the frontend, backend, and infrastructure. Responsibilities include owning systems end-to-end—covering architecture, implementation, deployment, and post-release improvements—while collaborating with machine learning, design, and product teams. The tech stack centers on React and TypeScript for frontend development, Golang and Rust on the backend, multi-cloud services including AWS, GCP, Cloudflare, and various LLM providers, alongside DevOps tools like Terraform and GitHub Actions. Applicants must possess at least **5+ years of experience** building and shipping full-stack products, with fluency in modern frontend development using React and TypeScript alongside backend engineering. Candidates need a solid grounding in systems design, performance trade-offs, and scalable architecture, paired with strong product judgment to balance velocity with foundational engineering investments. Because English is the company's working language, **proficiency in English** is required. The selection process involves a recruiter call, a live coding exercise, multiple technical interviews, and a presentation of a previous project.
