Markforged

We broke ground in 2014 with the world's first continuous carbon fiber 3D printer, and last year with the world's first sub-$100K metal printer. Our products are impeccably engineered and customers love us for it — our $70K printer has an NPS score of 85. We have < 10 software engineers and are looking for a few more. Our software stack: Webapp - Express.js / AWS backend, AngularJS / WebGL frontend, Electron for optional desktop client, all sanely-linted CoffeeScript. Computational geometry engine for part slicing - Written from scratch in CoffeeScript and C++. Runs on EC2, in-browser, or on desktop client. Printer touchscreen application - Node Webkit / AngularJS + Python -> migrating to Electron / VueJS + Python, all on top of a custom Debian image on a BeagleBone. Printer firmware - embedded C on a custom board. Our team is all super full-stack. We generally distribute software tasks based on individual interest. As our nth software engineer, you will have tons of project ownership. Your ideas will influence the company's direction. You will do interdisciplinary work on physical systems and learn from best-of-the-best engineers across MatSci, Mech-E, EE, and SW, mostly MIT grads. To succeed here, you need to be a quick learner and have a passion for software engineering. You don't need prior experience with 3D printing or our software stack, you can pick up those skills on the job.
