Location Applicants need to be legally allowed to work in the United States. This is a remote position with a strong preference for East Coast (US) time zone. Travel for occasional in-person collaboration is expected. The Opportunity We're seeking a skilled, senior Product Engineer who wants to own meaningful work end-to end, building features and driving from architecture to impact. You’ll be a key contributor to the Common platform, which visualizes networks of solidarity economy funders, organizations, and networks to facilitate collaboration, resource movement, and democratic governance. This is an exciting opportunity to build meaningful technology that serves community-led economic transformation at all scales. You'll have meaningful ownership over the features you build — from shaping decisions to driving them through to production. You should have experience working across the full stack and taking products from conception to production. What is One Project? One Project is a nonprofit social venture. We're building the infrastructure for a new kind of economy — one that benefits everyone. Communities worldwide are already creating alternatives to outdated economic systems that prioritize profit over people and the planet. One Project provides the technology and nurtures the network of alternatives, laying the groundwork for a sustainable, community-driven future. Why do we need a new economy? Today’s current economic systems reward profit over people and the planet. This misaligned incentive structure drives the current global polycrisis. When trees are valued more dead than alive, we end up with ecological devastation. When oil remains profitable to extract and sell, we end up with the climate crisis. When war is more profitable than peace, we end up with a military industrial complex that thrives on endless wars. At One Project, we spent our first few years researching these interlinked challenges and realized that we need to address the root cause: we need a new economy with different incentives. Our history and role We are not alone in this realization. All around the world, there is a growing ecosystem of communities, movements, and experts who are already working towards a just transition to a new economy. We launched in 2021 with a focus on listening to and supporting these change-makers, and today, One Project is a leading grantmaker in the new economy space ($32M to date). Our current direction is the outcome of what we heard from more than 300 field leaders, dozens of leading organizations, and extensive in-house research: One Project’s role is to build shared infrastructure and a network to move resources to community control. We call this infrastructure Common. What is Common? Common is a digital platform that connects people, organizations, and resources to coordinate, make decisions, and grow economic democracy to global scale.
