Description

Founding Rust Engineer Paris or Remote (Europe) About Twin Twin is building fully autonomous AI agents that run real business operations. You give a goal. Twin figures out the steps. It executes them end-to-end through APIs when they exist and through the browser when they don't. This is not another chatbot. This is not another workflow builder. We are building systems that can operate companies. In the first months of beta, users have already deployed more than 100,000 agents running lead generation, customer support, operations, trading systems, e-commerce workflows, reporting, and entire service businesses. 3M downloads) and Patrick Tourniaire We raised a $10M seed round led by LocalGlobe and are building with a small team of senior engineers. Why join Twin? Work on one of the hardest problems in software: making AI agents reliable enough to run real businesses. Build from first principles: many of the core abstractions don't exist yet. Small team, massive ownership: your decisions directly shape the product, architecture, and company. Rust at the core, product at the center: not infrastructure for infrastructure's sake. Design systems for both humans and AI agents: a new software paradigm that barely exists today. Early enough to matter: every engineer has outsized impact on what Twin becomes. What you'll work on Most AI companies are focused on generating text or code. We are focused on making AI systems reliably execute real work. You will work on some of the hardest problems in autonomous agents: Browser execution at scale Low-latency communication between agent subsystems Reliable orchestration of long-running workflows Memory systems that improve over time Self-healing execution architectures Agent infrastructure that s
