TL;DR - We’re looking for strong engineers (backend, frontend, or full-stack) who are excited about building agents. You’ll help shape how we build, evaluate, orchestrate, and scale LLM-powered agents in production - and define what it means to create truly lovable AI products.

Why Lovable?

Lovable lets anyone and everyone build software with plain English. From solopreneurs to Fortune 100 teams, millions of people use Lovable to transform raw ideas into real products - fast.

We’re a small, talent-dense team building a generation-defining company from Stockholm. We value extreme ownership, high velocity and low-ego collaboration. We seek out people who care deeply, ship fast, and are eager to make a dent in the world.

What we’re looking for

Core requirement: Strong engineering fundamentals. You might be backend, frontend, or full-stack - what matters most is your ability to build high-quality production systems.

Big plus if you:

  • Have built AI agents yourself (side projects count)

  • Are deeply curious about how AI systems behave and improve

  • Have worked with LLMs or AI systems in production

  • Are excited about experimenting with new models and techniques

Experience that stands out:

  • Shipped ML or AI features to real users with uptime requirements

  • Built evaluation systems or ML experimentation pipelines

  • Strong opinions on safety, latency, and helpfulness - but open to testing and learning

What you’ll do

In one sentence: Build, tune, and scale agents that power lovable products.

  • Add new agent skills and tools

  • Improve agent reasoning, orchestration, and efficiency

  • Design how multiple agents collaborate

  • Select the right models for different task types

  • Push the limits of what agents can reliably do in real products

  • Analyze agent behavior and performance

  • “Hill-climb” toward better helpfulness, safety, and reliability

  • Build evaluation frameworks and benchmarks

  • Create experimentation pipelines and feedback loops

  • Ensure agents perform well across real-world use cases

Our tech stack

  • React, Golang, and Rust

  • Serverless primitives on Cloudflare, k8s, GCP, Modal, Temporal
