Software Engineer (Platform)

Extend

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. 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. WHY YOU SHOULD CONSIDER JOINING * We've grown revenue 4x last year to several million ARR, with our growth continuing to accelerate * We have a product loved by users and being used in mission-critical flows at companies like Chime, Flatiron Health, Brex, Square, Zillow, Opendoor, Checkr, 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'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 * You'll get a front row seat to how a successful startup is built with plenty of leadership opportunities as we grow quickly 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 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.

Outtake

ABOUT OUTTAKE Outtake exists to empower and facilitate trust for a digital-first world. Today, impersonation, fraud, AI-driven scams, and identity abuse spread faster than any security team can respond to. So we built something different: an agentic AI platform that proactively detects, monitors, and takes down impersonators, automating protection in hours, not weeks.   Built by ex-Palantir, ex-CTO/founders, and ex-Notion engineers, Outtake is designed for clarity, autonomy, and velocity. Our goal is ambitious: become the trust layer of the modern internet. And we intend to do it with a lean, dense, exceptionally talented team.   Outtake is backed by top-tier investors and operators who believe in our mission and our model. With strong financial footing and a long runway, we prioritize creating an environment where people can do the best work of their careers. ABOUT YOU Engineering at Outtake is built on ownership, clarity, and end-to-end impact. We hire entrepreneurial generalists who think in systems, not tickets — people who want to design architecture, ship fast, and solve problems that span the entire stack. Our teams are flat and autonomous: engineers ship fast, make product decisions, and own outcomes from concept to deployment. We optimize for grit + velocity, which means every engineer operates with the scope, influence, and equity of a future CTO. Our goal is to bring on engineers who will grow with Outtake's trajectory - and because of the responsibility, autonomy and talent density here. WHAT WE'RE LOOKING FOR When the life-support systems on your Mars habitat begin to fail, are you the engineer the team trusts to hack together a solution in hours? No worries, neither are we - but we DO want you to be the type of engineer who is unafraid to dive into any part of the codebase to accomplish the mission. Often getting the job done involves building functional v0s that eventually evolve into scalable production systems. Can you navigate this journey effectively? Do you have well reasoned opinions that rapidly update to new information - whether from customers, peers, or the environment? WHAT YOU’LL ACHIEVE * Contribute to the whole platform - whether it’s in the BE where you tinker with agent framework that achieves all complex tasks or the FE where you make our incredibly powerful workflows simple & intuitive. * Partner with customers who are some of the most socially meaningful individuals on the planet - these brands, reputations, and names move billions daily. * Work with an elite team with high success track record at prior companies & become a better version of yourself in the process. * Learn the ability to carry zen into any situation of chaos as you continuously overcome obstacles and fully grow into your abilities. * Become a leader as Outtake grows and define the culture of a high impact organization. WHAT YOU’LL NEED TO BRING * Proven track record of execution: 2+ years experience as software engineer building world class products. * Thoughtful problem solver: You approach problems holistically, starting with a clear and accurate understanding of the context. You think critically about the implications of your decisions, and are able to consider both the business and the technical tradeoffs of your solutions. * Not ideological about technology: To you, technologies are about tradeoffs. You may be opinionated, but you’re not ideological, can learn new technologies and are receptive to new ideas. * Organized and self-sufficient: You are comfortable managing yourself, navigate ambiguity and finding ways to create impact. * Owner of your mission: You are a owner of the products that you create, meaning you take pride in the quality, maintenance and understandability of the products you build and the code you write. BONUS POINTS IF… * You have experience working in a high growth early stage startup. * You have experience building agents, or fine-tuning LLMs to accomplish complex tasks. * You have experience in building large scale content indexing systems. * You’ve built apps or are familiar with our stack - NextJS, React, Typescript, tRPC, Vercel, Postgres. LIFE AT OUTTAKE * Office: For those in NY, we are an in-person team (5 days a week, with flexibility as needed) working out of a stunning waterfront office in Brooklyn. Collaboration, speed, and clarity matter. * Health: 100% company-paid medical, dental, and vision for employees. * Time Away: Flexible PTO. We trust adults to manage energy, not clock time. * Culture & Team: Annual company retreats and regular in-person events. Outtake is an equal opportunity employer. We are committed to building a diverse, inclusive team.

Outtake

ABOUT OUTTAKE Outtake exists to empower and facilitate trust for a digital-first world. Today, impersonation, fraud, AI-driven scams, and identity abuse spread faster than any security team can respond to. So we built something different: an agentic AI platform that proactively detects, monitors, and takes down impersonators, automating protection in hours, not weeks.   Built by ex-Palantir, ex-CTO/founders, and ex-Notion engineers, Outtake is designed for clarity, autonomy, and velocity. Our goal is ambitious: become the trust layer of the modern internet. And we intend to do it with a lean, dense, exceptionally talented team.   Outtake is backed by top-tier investors and operators who believe in our mission and our model. With strong financial footing and a long runway, we prioritize creating an environment where people can do the best work of their careers. THE ROLE This is a product engineering role in the strongest sense of the term. You work close to customers. We believe customer proximity is a competitive advantage. Engineers talk directly to customers, join calls, and participate in tight feedback loops. Forward-deployed work is part of the job - not as support, but as the fastest path to product insight. You shape what we build. Engineers here don't wait for fully formed specs. If you see a problem worth solving, you're expected to make the case, design the experiment, and build the v0. Good product judgment is valued as highly as clean execution. You ship across the stack. You'll work wherever the problem is - backend systems processing TBs of internet-scale data, frontend workflows that make complex analysis feel intuitive, agent frameworks that automate what used to take weeks of manual work. Titles matter less than ownership. You operate with clarity and focus. Mondays we align. Fridays we retro. In between, you're trusted to prioritize what matters most - while staying sharp to signal from customers and the market. THE TEAM "The team you build is the company you build." — Vinod Khosla You'll work alongside engineers from Palantir, Notion, Meta, Microsoft, Slack, and Datadog. Several have founded startups. But credentials aren't the point. This team cares deeply about craft, slope, and truth-seeking. People pair on hard problems, challenge each other in code review, and give direct, thoughtful feedback in 1:1s. Mentorship is intentional, not accidental - you'll learn faster here because the bar is high and the coaching is real. We're building Outtake to be a long-term network of builders: people who go on to lead teams, start companies, and back each other over decades. The goal is simple - working here should make you meaningfully better. YOU This role tends to excite people who've built something from scratch and want to do it again - with better tools, sharper teammates, and real distribution. You might be a fit if: * You've shipped products that users actually used - and at least one that failed, and you understand why that mattered * You ramp quickly, thrive in ambiguity, and have a strong bias to action * You care deeply about why something is being built, not just how * You understand what success looks like for the customer and the business, not just the code * You've done some form of forward-deployed or customer-embedded engineering and found it energizing If you need a roadmap handed to you, this won't be a fit. If you want to help write the roadmap, you'll feel at home. Bonus if you've: * Founded something (even if it didn't work) * Worked in forward-deployed or customer-embedded roles * Built with agents, LLMs, or large-scale data systems WHAT SUCCESS LOOKS LIKE What will you have shipped by month 6 that customers are asking about by name? The engineers who thrive here tend to find a problem early - something they heard on a customer call, noticed in the data, or couldn't stop thinking about - and make it theirs. Within a few months, they've built something real: a detection capability that catches what we were missing, a workflow that cuts hours of manual work, a system that makes the next ten features possible. By month 12, you're not waiting for direction. You're the person others come to for a specific problem space. Customers know your work. Teammates trust your judgment. And you've shaped what Outtake builds next. WHY OUTTAKE If you're choosing between us and another AI startup: * Foundation models are infrastructure. We're building what people actually use to stay safe. * The impact is immediate and real - attacks stopped, fraud prevented, threats caught that humans miss. * The company is working: real customers, real revenue, real momentum. * The people are exceptional - not just in pedigree, but in how they think and build. * The network compounds: your teammates become future founders, collaborators, and references. * The upside is meaningful. Equity reflects impact, not title.
