Senior Full Stack Engineer

About Learning Tapestry
Hi! We're Learning Tapestry. We're a 25+ person all-remote, global organization dedicated to making digital learning "just work" for educators and learners alike. We solve hard problems in complex education technology environments. We’re a triple bottom line company: we make a profit like any good business; our work makes the world better (“social impact”); and we strive to create a healthy internal work environment for everyone who works here. For our staff we believe in flexible work locations and working arrangements. We empower all of our team members to manage their schedules and adjust as necessary. We're focused on results and impact, not locations and hours. We hire people with great technical ability, but we also expect everyone at Learning Tapestry to have strong character and solid communication skills. We highly value effective software architecture, test-driven development methods, and good project management methodology. We believe in having a strong CI and deployment pipeline that enables us to focus on writing good software.

What We’re Looking For
You’re an exceptional professional software engineer with at least 8 years of software engineering experience. You’re comfortable in multiple languages, but in particular you are strong in backend coding using Ruby or Node.js, and frontend engineering React (or you are expert in an alternative frontend framework and are willing to learn/use React for some projects). Our ideal candidate is available 30-40 hours per week, with at least 4 hours overlapping with business hours in the US Eastern time zone, and at least 1 hour overlapping with business hours in the US Pacific time zone. We ask everyone who works here to be fluent or strongly proficient in written and spoken English, and easily understood by US-based speakers (we ask for this to allow everyone in the company to be able to communicate with each other, rather than having to go through intermediates). Please read through this entire job description before applying, as there is critical information about how to apply included. Please do not apply by reaching out to other emails or individuals.
