Job details

Design Engineer

Extend is building a modern document processing platform, reimagined with LLMs. We're on a mission to transform how the world works with unstructured data.

We believe great design is critical to how AI bridges the gap between theory and production deployments. As a Design Engineer at Extend, you'll craft the interfaces that make complex document processing feel simple.

Why you should consider joining

We've grown revenue 15x this year to 7-figures in ARR, with our growth continuing to accelerate
We have a product loved by users and being used in mission-critical flows at companies like Brex, Checkr, Opendoor, Chime, and many more
We're building the next generation document processing platform — the market for document processing has expanded 1000x due to LLMs, and existing solutions are all low NPS
We're punching well above our weight, supporting customer and revenue metrics with half the team size of other startups — everyone joining at this stage will have outsized impact

We have a very talent dense team (e.g. former founders, world record holders) operating in a high performance culture, in-person in NYC, with high equity ownership
We're tackling novel, unsolved problems at the intersection of LLMs, complex data processing, and human ↔ AI interfaces
We're backed by world class investors, including YC, Homebrew, investors from OpenAI, and more

We're a lean team, and our customer base is growing too fast for us to keep up. We're looking for talented engineers to join our founding team ahead of our next round and execute on an ambitious roadmap.

Impact

We're creating entirely new interaction patterns for how humans work with AI systems. The interfaces we build directly impact how quickly and confidently customers can deploy AI into production. Here's a few of the complex design challenges we're working on:

How do we visualize AI decision-making in a way that builds user trust?
How do we create interfaces that gracefully handle both automation and human-in-the-loop scenarios?
How do we design feedback loops that help users improve document processing performance over time?
How do we build interfaces that work for both technical and non-technical users?
How do we maintain a cohesive experience as we rapidly ship new capabilities (e.g. extraction, classification, splitting, fraud detection)?

Role

Own the end-to-end design process from conception to implementation, working closely with engineering and product
Build and maintain our design system, ensuring consistency and quality across all product surfaces
Implement high-quality interfaces in React, Typescript, and Tailwind
Have complete ownership over the work you do — as a founding team member, you’ll have the opportunity to truly own large areas of customer success and have direct relationships with large enterprises.
Work directly with the CEO, CTO, and other founding members and help build out our team.

Ideal Candidate Credentials

5+ years of experience as a product designer, frontend engineer, or similar role combining design and implementation
Strong portfolio demonstrating experience designing and building complex web applications
Deep expertise in modern frontend technologies (React, TypeScript, modern CSS)
Track record of shipping intuitive interfaces for developer tooling products
Experience designing interfaces for AI products or ML-powered features
