Join Zeffy, the fastest-growing nonprofit platform in North America. As a Senior Software Developer, you'll play a key role in building and scaling technology for charities. You'll take ownership of impactful projects, shape our processes, and mentor others. Our stack includes React/Next.js, Nest.js, PostgreSQL, and Algolia. Previous experience in these technologies is not required, and we offer focused onboarding and internal bootcamps.
About the role
We’re looking for someone with at least 4 years of experience as developer, ideally in SaaS or web-based products. We move fast by keeping things simple, and we want someone who shares that mindset: experienced enough to know when to push for structure, and wise enough to know when to cut the noise and just build. * you’ve built real products, learned from trial and error, and developed the instinct to separate what truly matters from what doesn’t. * you bring seniority through judgment, not hierarchy — through the ability to make smart, pragmatic decisions that balance quality and speed. * you value clarity over complexity, progress over perfection. You mentor others with empathy, share what you’ve learned, and help elevate the team without slowing it down. If you’re fed up with unnecessary complexity — endless processes, over-engineered solutions, or meetings that don’t move the work forward — you’ll feel at home here. *💡 Research shows that candidates from underrepresented backgrounds often don't apply for roles if they don't check every box. If this applies to you and you are interested in the position, we'd love to hear from you!*Key missions
