Founding Product Engineer

Build the Future of Autonomous Companies

At Twin, we're building a world where anyone can deploy AI agents capable of running real business operations.

Not chatbots.

Not copilots.

Autonomous agents that take actions, make decisions, execute workflows, and create value.

In just a few months, we've seen explosive adoption, thousands of users building businesses on top of Twin, and millions of agent actions executed.

We're still at the beginning.

We're looking for a Founding Product Engineer to help build the company that builds companies.

The Role

This is not a traditional software engineering role.

You won't receive tickets from a product manager.

You won't spend months discussing roadmaps.

You won't optimize a tiny corner of an existing system.

You'll work directly with founders, users, and other builders to design, build, and ship product every day.

You'll move across product, engineering, design, AI, infrastructure, and growth whenever needed.

One day you might:

Build a new agent capability from scratch
Design an onboarding flow that doubles activation
Improve infrastructure supporting millions of executions
Talk directly with power users
Ship a feature in the morning and iterate on feedback the same afternoon","datePosted":"2026-06-01","employmentType":"FULL_TIME","hiringOrganization":{"@type":"Organization","name":"Twin","sameAs":"https://twin.so"},"url":"https://jobs.ashbyhq.com/twin-so/30eadc1c-e4ab-431e-a5b5-e767cc63b910","jobLocationType":"TELECOMMUTE","jobLocation":{"@type":"Place","address":{"@type":"PostalAddress","addressLocality":"Remote"}}},{"@context":"https://schema.org","@type":"JobPosting","title":"Research Engineering Internship","description":"

About Twin

Twin builds autonomous agents that are reliable and scalable enough for companies to actually delegate work to them. We engineered the first commercial agent deployed to 500k SMBs — Invoice Operator — achieving 95%+ accuracy at a fraction of the human cost. Over the coming months, we expect this first agent alone to automate millions of man-hours.
To achieve this, we've built, among other things:
- A Rust-based browser infrastructure, maintaining low latency at high scale and concurrency
- A password manager enabling secure and automated agent authentication, including solving 2FA
- A graph-based agent framework, making complex agents robust through modularity and decoupling
- A self-correcting infrastructure, allowing agents to learn from mistakes and continuously improve as they encounter new challenges
Founded in 2024, we've raised €12M from LocalGlobe and the founders of companies like Hugging Face, Datadog, and Alan. Our ambition: launch and distribute the next generation of high-impact agents, and become the trusted layer where autonomous work runs.
About the Core Platform team

The Core Platform team builds the foundational infrastructure powering Twin's high-performance, Rust-based agent engine. This engine manages browser automation, communication between agents and humans, and the evaluation and testing pipelines that keep our agents best-in-class.

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.
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.
