We're looking for engineers to come work with us on EAS Build and Submit. The responsibilities of this role are to design, implement, and operate new developer-facing features as part of these services. You'll also work on internal-facing improvements that make it easier for us to manage our services, optimize speed and costs, and generally make it enjoyable to work at Expo. You'll need to write software that runs correctly and efficiently and be responsible for its uptime and performance. Each engineer at Expo is responsible for the code they write, including adding tests and monitoring and being part of their team's on-call rotation.
