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.
Beyond scaling our first agent, our goal is to launch & distribute our next hit agents and ultimately become the trusted layer where autonomous work runs.
About the product team
The product team is responsible for the design and the development of our interfaces - from dedicated interfaces for our agents, to internal observability and testing apps, to the interface between our agent engine and agent engineers.
The objective of the team is to come up with innovative human-agent interfaces to improve stickiness and usability of our agents and our agent builder.
About the position
We are looking for an engineer who enjoys owning the entire product surface: mostly front-end, with a sprinkle of backend when things need to plug together. Obsessed with building and shipping delightful experiences, and a first principle thinker that can solve the frictions in human-agent interactions.
You will join a small, product-focused team working hand in hand with agent engineers and core platform engineers - that will lead pave the way for agent-human interactions.
Daily tasks
Design and implement new features for the Twin web app
Work closely with agent engineers to integrate backend APIs
Iterate on interfaces and UX together with our design team
Contribute to internal tooling and dashboards
Requirements
Proficiency in Typescript and React
Comfortable working on backend APIs when needed
Svelte knowledge and a good eye for design are a plus
High agency and hardcore work culture
