Twin Labs - Founding Rust Engineer

• Package €200K – €250K • Offers Equity • We believe exceptional people should be rewarded like owners, not employees. • Most companies optimize compensation around salary. We optimize around value creation. • That means we aim to provide a strong cash package, but we intentionally place a significant portion of the upside in equity. Not because it's cheaper for the company, but because we believe the people building the future of Twin should directly participate in the value they create. • We're not looking for people who want to maximize next year's income. We're looking for people who want to maximize the value they can create over the next decade. • At Twin, we think of our team as founders in spirit. The decisions you make, the products you build, and the speed at which you execute can materially change the trajectory of the company. When that happens, we believe you should benefit from it. • For many startups, equity is a lottery ticket. • We don't view it that way. • We view equity as ownership in a business that is already proving product-market fit and is scaling at an extraordinary pace. • Our goal is simple: • Provide enough cash so you never need to worry about paying your bills. • Provide enough ownership so that if Twin succeeds, it can be genuinely life-changing. • We want every person who helps build Twin to have the opportunity to share meaningfully in the outcome. • Founding Rust Engineer • Paris or Remote (Europe) • 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. • Twin was founded by Hugo Mercier , CEO (founder of Dreem, $60M raised, 150+ employees, acquired) and João Justi, CTO (cryptography, compilers, virtual machines, distributed systems, ex-Zama) but also Julius de Bruijn, creator of Tiberius (3.3M downloads) and Patrick Tourniaire • We raised a $10M seed round led by LocalGlobe and are building with a small team of senior engineers. • Work on one of the hardest problems in software: making AI agents reliable enough to run real businesses. • Work on one of the hardest problems in software: • Build from first principles: many of the core abstractions don't exist yet. • Build from first principles: • Small team, massive ownership: your decisions directly shape the product, architecture, and company. • Small team, massive ownership: • Rust at the core, product at the center: not infrastructure for infrastructure's sake. • Rust at the core, product at the center: • Design systems for both humans and AI agents: a new software paradigm that barely exists today. • Design systems for both humans and AI agents: • Early enough to matter: every engineer has outsized impact on what Twin becomes. • Early enough to matter: • 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: • 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 survives failures • Product features used directly by customers • Internal systems that AI coding agents can understand, operate and extend • Part of the challenge is not simply writing software. • The challenge is designing systems that remain understandable and modifiable by AI coding agents themselves. The way we build software internally increasingly assumes that both humans and coding agents will interact with the codebase. • We're building for the long term and want people who think like owners. • Last words • The software industry spent the last decade building SaaS. • The next decade will be about autonomous companies. • We believe AI agents will not just assist people. • They will operate businesses. • If that future sounds inevitable to you, we'd love to talk.
