Where are you going to work?

At 510, we're scaling up our digital products to maximize humanitarian impact around the world. To support this, we’re strengthening our software engineering capacity and looking for a Full Stack Software Engineer to join the team.

You’ll contribute to building reliable, scalable tools that support our humanitarian operations. You’ll work across the stack with TypeScript, Node.js, PostgreSQL, and modern front-end frameworks, and collaborate closely with designers, product managers, and data specialists.

You’ll report to the Software Engineering Lead and work with a friendly, skilled team of engineers (currently 8 and growing). Our culture encourages learning, pairing, mentorship, and healthy work-life balance.

What will you be doing?

Within 3 months:

• Get to know the team, our workflows, and the humanitarian context we work in.
• Start contributing to both front-end and back-end codebases.
• Write business logic, APIs, and developer/user documentation.
• Collaborate on responsive web apps using modern frameworks.
• Add unit and integration tests to help maintain our code quality.

Within 6 months:

• A good understanding of API development and writing maintainable, well-tested code.
• Experience with unit and integration testing, Git workflows, and containerized development using Docker.
• Comfort working in agile teams and communicating across disciplines (e.g., design, product, data).

Who you are

• You care about writing clean, maintainable code.
• You're curious and always learning.
• You enjoy solving problems and helping others do their best work.
