What will you be doing?

As a member of our software engineering team, within the first three months, you will immerse yourself in understanding the team dynamics, our workflows, and the unique challenges of the humanitarian context in which we operate. Your proactive engagement will facilitate your contributions to both front-end and back-end codebases.

The ideal candidate should have between 3-10 years of professional experience as a full stack developer, showcasing strong proficiency in TypeScript and solid backend development skills, particularly with Node.js and PostgreSQL.
