Job Description

Senior Fullstack Developer building and scaling features for a global fundraising platform utilizing Node.js and React. Contribute to a mission-driven engineering culture focused on impactful solutions.

Responsibilities:

  • Design, build, and maintain resilient frontend and backend features using React and Node.js.
  • Develop our core products, including donation checkouts, embeddable widgets, and donor/partner portals.
  • Architect and develop system components that scale across millions of monthly transactions.
  • Write clean, well-documented, and thoroughly testable code.

Requirements:

  • Experience with Webpack configuration, performance optimization, and profiling.
  • A keen eye for detail and a high sense of ownership and accountability for your work.

Benefits:

  • 31 days off
  • 100% paid telemedicine plan

  • English learning courses.

  • Gym or swimming pool.
  • Co-working.
  • Remote working.
