Extend provides an AI-native platform that converts complex, unstructured documents such as PDFs into highly accurate, production-ready structured data.
Extend https://extend.app is building a modern document processing platform, reimagined with LLMs. We're on a mission to transform how the world works with unstructured data. As a Software Engineer at Extend, you’ll be responsible for building our core platform that companies use to configure, test, and deploy document processing. We’re looking to hire exceptional engineers who care about crafting intuitive product experiences, relentlessly focus on the details, and operate with high agency.

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 powering mission-critical data processing at companies where if we get things wrong, there are real world impacts (e.g. missed payments, people can't move into homes on time). Here's a few of the complex technical problems we're working on: - How do we enable enterprises to deploy LLM-powered document processing into production with confidence? - How do we handle never before seen edge cases in customer data? - How do we build a self-correcting system that automatically gets better over time? - How do we enable non-technical domain experts to improve models with their expertise & business logic? - How do we help customers make tradeoffs between latency, cost, and performance? - How do we build reliable systems that can process large data streams in real-time? ROLE - Build, and maintain, durable, scalable systems capable of processing 10s of millions of data points per month. - Design and implement the best human ↔ AI interfaces for designing and understanding document processing. We are building a new territory of UX that previously did not exist. It’s up to us to discover and implement new patterns that work for our users. - Have complete ownership over the work you do — as a founding team member, you’ll have the opportunity to truly own large areas of product and engineering and have direct relationship with customers. - Work directly with the CEO, CTO, and other founding members and help build out our team.
