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.

Developer experience is our competitive advantage. As our Developer Experience Lead at Extend, you'll ensure we become the default choice for developers building document processing.

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 need to set a new standard for what great developer experience looks like in the AI era.

Here's a few of the complex challenges you'll be working on:

• How do we make it incredibly simple for developers to get started with Extend?

• How do we build developer trust in AI-powered systems?

• How do we create documentation that serves both beginners and power users?

• Document processing is a massive space and has fascinating technical challenges — how do we build a thriving developer community around document processing?

• How do we enable developers to quickly troubleshoot and optimize their implementations?

• How do we gather and incorporate developer feedback into our product roadmap?
