Job description

TL;DR: We're seeking exceptional senior engineers and technical leaders for our Product team to help build the future of AI software creation. You will work across our entire stack to build features that will empower the next generation of creators and builders.

What we’re looking for

• 10+ years of experience designing, building, and shipping production products, with a track record operating at senior engineering levels.
• Deep experience across the full stack, or strong backend depth - fluent in modern frontend (React/TypeScript) and/or backend (Golang, Rust) development.
• Solid understanding of systems design, performance tradeoffs, and scalable architecture for products serving millions of users.
• Strong product sense and the ability to make well‑reasoned technical decisions - knowing when to prioritise speed and when to invest in foundational work.
• You own systems end‑to‑end: architecture, implementation, deployment, monitoring, and iteration.
• 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

• Build and scale the systems that power Lovable products, ensuring they're fast, reliable, and ready to support millions of users.
• Implement and maintain features across the stack - frontend, backend, and infrastructure - owning them from architecture through to production.
• Design, implement, and maintain backend services, APIs, and infrastructure components built for scale.
• Collaborate closely with ML, design, and product teams to translate capabilities into intuitive, mind‑blowing user experiences.
• Drive the full development lifecycle, from technical planning to production launch and post‑release iteration.
• Contribute to shaping our technical direction, engineering culture, and product strategy.

Our tech stack

We're building with tools that both humans and AI love:

• Frontend: React
• Backend: Golang and Rust
• Cloud: Cloudflare, GCP, AWS, Many LLM providers
• DevOps & Tooling: Github Actions, Grafana, OTEL, infra-as-code (Terraform)
