This is an opportunity to have significant ownership and impact, while also building on an existing technical foundation. About Quarter20 Quarter20 is a next-generation platform that automates technical hardware documentation and collaboration for hardware development. We help engineers and their manufacturing teams automatically create build instructions and documentation, accelerating the timeline from design to manufacturing. Quarter20 was founded by Mai Bui and Addy First, a hardware engineer and software go-to-market specialist hailing from teams at SpaceX, Tesla, and Microsoft. We are venture-backed by top investors and technologists. Our customers range from leading medical devices incumbents to agricultural robotics startups. We are a fast-growing startup and looking for awesome people to grow our product, vision, and culture. What we do Let’s be real - no one likes making documentation; it’s annoying and time consuming. But the process is 10x worse for hardware. Building hardware is complex, and unlike software, collaborating on hardware requires visual representation of the product, like 3D models and 2D drawings. Imagine if you were building a rocket and the best software tools that you had were Snipping Tool and generic solutions like Google Slides. Unfortunately, this is the reality for those not only in aerospace, but also in automotive, consumer electronics, and robotics - any company building hardware! Quarter20 is redefining the workflow for hardware engineering, starting with build documentation. We are creating the first-ever platform that, using 3D CAD as an input, can automatically generate the documentation that you need for hardware development, from product requirement docs, to test plans, to Bill of Materials, to build instructions, and more. What you’ll do Build rich, high-performance, data-driven experiences that power Quarter20’s core single-page application Create a new class of web editor (like Notion or Figma) that transforms CAD data into automated manufacturing documentation Explore and apply new algorithms, tools, and libraries to push the limits of real-time renderings of complex 3D models Partner closely with backend engineers to design and evolve APIs and data models that support real-time, interactive experiences Work hand-in-hand with product, design, and customers to rapidly iterate on features used daily by hardware teams Continuously improve frontend architecture, performance, and tooling as the product scales Set a high bar for frontend quality, reliability, and user experience across the product This may be a good fit if you have 5+ years of experience as a frontend software engineer Note: Degree in computer science not required!
