We are already working with more than 80,000 nonprofits and are doubling annually.\nMillions of people dedicate their lives to causes beyond profit, running schools, shelters, and community initiatives. Yet most still lack modern tools. We believe the greatest opportunity for technology today is to amplify the impact of nonprofits.\nBuilt on a sustainable, self-funded model, Zeffy reaches over 1M donors monthly and grows profitably, giving us the freedom to focus fully on our mission.\nNonprofit workers are heroes. They deserve the best technology, and we’re hiring top minds and top hearts to build it for them.\nAbout the role\nAs a Staff Software Engineer at Zeffy, you’ll work on key product features while playing a central role in elevating the engineering team.\nYou’ll bring experience that helps others make better technical decisions, navigate complexity with confidence, and maintain our focus on building simple, high-quality solutions as we grow.\nDevelopment Principles at Zeffy\nWe always optimize the ratio impact / effort, it’s what we call Zeffy perfectionism, perfection in impact.\n\nWe build the simplest solution first to validate ideas quickly, keeping the codebase clean without solving problems that don’t exist yet.\n\nWe are organized in 2 months cycle, to make sure we prioritize radically. We set ourselves targets on the 4 following dimensions: efficiency, security, stability and performance.\n\nTrust and ownership: every target is clear and owned by one person who has full autonomy to reach it. Owned by one person doesn’t mean working alone on it.\n\nContinuous improvement: We regularly review and refine our processes, promoting a culture of learning and growth through feedback.\n\nRead more: https://zeffy.notion.site/Zeffy-Engineering-Blog-3505553ff3658091becedbbd71f70ece\nOur Stack\nFrontend: React/Next.js (Typescript)\n\nBackend: Nest.js (TypeScript)\n\nDatabase: PostgreSQL, Algolia\n\nCI/CD: GitHub Actions, Cypress\n\nPreferred experience (qualifications)\nWe’re looking for someone with at least 8 years of experience as a developer in SaaS or web-based products that serve high-volume and rapidly growing user bases.\nWe move fast by keeping things simple, and we want someone who embodies that mindset: someone who knows when structure adds value, when it gets in the way, and how to guide others toward the right balance.\nYou’ve shipped complex products at scale, learned from real-world successes and failures, and developed sharp judgment about what truly matters.\n\nYou bring seniority through expertise and perspective rather than hierarchy, making clear, pragmatic decisions that balance speed, quality, and long-term thinking.\n\nYou value clarity over cleverness, simplicity over complexity, and momentum over perfection.\n\nYou mentor others with empathy, share your experience generously, and elevate the work of the whole team without adding unnecessary process.\n\n Research shows that candidates from underrepresented backgrounds often don't apply for roles if they don't check every box.
