We’re admired by well-known civic orgs, influencers, candidations/politicians, and voters alike. Voting group leaders across the country and ideological spectrum use Sway to organize their communities, share ballot recommendations, and — most importantly — win elections. Our tight-knit team is looking to add an additional full-stack engineer to make sure we meet the moment. How we work together: Our engineering team is 3 FT and 3 senior contractors. We’re high agency and ownership. We use every AI tool under the sun, and we all work across the stack. Speaking of our stack, we’re a bit spoiled: a React-based frontend built with Next.js, a real-time GraphQL API layer powered by Hasura (no boilerplate!), and backend services written in Typescript. We work in-person in SF, love team lunches, and are still happy to see each other on the weekend. We host civic-oriented events in our community. We have our power users on speed dial. We talk politics, and often do not agree. At the end of the day, we know that our work is critical, and that there are few cooler problem spaces to be working in right now. We strive to balance that gravity with lightness every day. Who you are: We’re looking for someone who does it all, and well, but with a special emphasis on product-mindedness and/or a love of messy (but very interesting) data. You’ve built with many of the tools in our stack. You’re excited about and capable of using cutting edge tools to your advantage. You ship fast and pick things up on the fly. Maybe you’ve built a consumer product from scratch or started something yourself. Politics would be better with you involved. Benefits: Competitive comp, flexible PTO, full benefits, and ground-floor equity in a company trying to reinvent political power. ## About Sway ## Company Overview - **One-liner**: Sway is a material innovation company scaling compostable solutions for plastic made with seaweed. - **Entity Type**: Private (Seed stage; $10.6M total funding) - **Headquarters**: San Francisco, California, United States - **Founded**: 2020 - **Founders**: Julia Marsh (CEO & Co-Founder), Matt Mayes (COO & Co-Founder) ## Core Business - **Primary industry**: Climate Technology Product Manufacturing; sustainable packaging / biomaterials - **Target customers**: B2B – brands in fashion, outdoors, home goods, personal care, and other industries looking for compostable flexible packaging; also partners with packaging distributors and manufacturers. - **Mission statement**: “Create materials that replenish the planet” – enabling a circular economy from sea to soil. ## Products & Services - **[Sway Flexible Film](https://swaythefuture.com/hello)**: Seaweed-based, compostable flexible film for bags (shopping, shipping, polybags, die-cut handle retail bags).
