About Zeffy

🌬 At Zeffy, we believe nonprofits need access to the best technology to have more impact, but most of them don’t have any budget left for technology. That’s why we have developed a powerful fundraising platform and made it entirely free! Our mission is to empower all nonprofits to solve the world’s biggest problems.

🚀 With 50,000+ nonprofits using Zeffy, we are at an exciting stage of our journey. We have helped nonprofits raise $1 billion, and with 200% year-over-year growth, we aim to support more than 300,000 nonprofits by the end of 2026.

🌱 Zeffy is a B-Corp company with a dedicated team and ambitious goals. We’re here to make a difference, driven by the will to create a better world.

 

About the role:

We’re looking for our third Lead Developer as we grow from 2 to 3 squads. It’s a pivotal moment where we can no longer fit all engineers in one meeting. It’s the perfect time to help shape our team structure and development processes. You’ll play a key role as we expand from a single product to multiple lines, and scale our platform from 2M to 10M weekly users. Along the way, you’ll tackle challenges in scalability, security, performance, and efficiency, all while helping nonprofits thrive and fueling Zeffy’s growth. 💫

In this role, you’ll get to:

• Bring your experience of scaling teams and codebases.
• Lead your squad of developers by running rituals, holding one-on-ones, coaching junior team members, and ensuring the squad meets its efficiency goals.
• Represent your squad during the General Retro Meeting (Product, Customer Success, Tech, Leadership) and the General Tech Meeting.
• Act as Hiring Manager for recruitment within your team.
• As an Individual Contributor, you lead by example through your efficiency and impact.
• Proactively suggest and drive improvements in our tech stack and company-wide processes.
• Ensure your squad consistently applies Zeffy’s best practices through high-quality coding, thoughtful reviews, coaching, and day-to-day leadership.

Development Principles at Zeffy:

• We always optimize the ratio impact / effort, it’s what we call Zeffy perfectionism, as opposed as classic perfectionism.
• We avoid over-engineering and anticipating problems too much, the codebase stays clean and efficient.
• That doesn’t mean we only deliver short-term dirty code, we just iterate by delivering the most simple solution first in order to validate the idea and the adoption before making sure it’s scalable.
• Every 2 months, we set ourselves targets on the 4 following dimensions: efficiency, security, stability and performance.
• Trust and ownership: every target is clear and owned by one person who is flexible to reach it; owned by one person doesn’t mean working alone on it.
• Continuous improvement: We regularly review and refine our processes, promoting a culture of learning and growth.

Our Stack

• Front-end: React (JavaScript), Next.js (TypeScript)
• Back-end: Nest.js (TypeScript)
• Database: PostgreSQL, Algolia
• CI/CD: GitHub Actions, Cypress
• Other tools: GraphQL, TypeORM, Git & GitHub, AWS
