Staff Software Engineer

We’re looking for a talented and motivated Staff Software Engineer to join our Supporter Experience team. This team is responsible for increasing the number of signatures on petitions by optimizing sharing behavior and engagement across the platform. You will work on projects that directly impact our most important business metrics by improving how users share and spread petitions.

We’re a social impact business (a public benefit company) and the world’s largest social change platform, with 100 million monthly users, over 40,000 campaigns launched on the site every month, and a 100% user-generated, profitable revenue model. Our users win campaigns for change once every hour. In the last decade in Mexico, from the mobilization against the Maya train to the campaign to increase vacation days, many nationwide movements were created on our platform. From campaigns like Cáncer Warriors to calls for the release of the elephant Eli, dozens of local, national, and international victories happen every day thanks to the power of our users who are changing our country.

Key Outcomes

• Growth Optimization: Lead the technical strategy and execution of features that maximize share frequency and effectiveness, driving sustained improvements in the platform’s virality and user reach.
• Share Experience Enhancement: Architect and guide improvements to sharing experiences across key user touchpoints—such as post-sign flows and supporter journeys—ensuring consistency, scalability, and measurable impact.
• New Engagement Opportunities: Drive innovation in sharing and engagement, identifying and leading the development of new experiences including role-based flows, personalization strategies, and emerging channels like TikTok, YouTube, and Discord.
• Supporter Engagement: Set the technical direction for enhancing supporter communication systems (e.g., email, notifications, engagement pages), ensuring they are performant, personalized, and aligned with user behavior and engagement goals.
• Cross-Functional Collaboration: Act as a technical leader in cross-functional planning and execution, aligning engineering efforts across product, design, and data to create cohesive, scalable systems that amplify user participation and campaign success.

This role includes participation in our on-call rotation.
