How to Apply for Part-Time Contract Developer, GiveWise

at Effective Altruism Hong Kong

🏢 About Effective Altruism Hong Kong

Effective Altruism Hong Kong is a charity dedicated to helping people apply EA principles through effective giving guidance and impactful programs. Working here means contributing to a mission-driven organization that prioritizes evidence-based approaches to doing good, with a lean team where your work has direct impact.

About This Role

As the primary software developer for GiveWise, you will own the entire technical stack of a donation platform, from building features in React/TypeScript and FastAPI/Python to maintaining Stripe payment flows and optimizing PostgreSQL queries. This role is impactful because you'll directly enable effective giving by ensuring a seamless, reliable donation experience for users.

💡 A Day in the Life

You might start by reviewing any user-reported issues or Stripe payment logs from overnight. Then, you'd pick a feature to work on—like building a donation receipt UI in React or optimizing a slow database query in PostgreSQL. You'd likely have a brief async check-in with the team, then dive into coding, testing, and deploying changes independently. The rest of your day could involve writing documentation or planning the next sprint's technical tasks.
