We design and build custom applications and services used by millions. We are creating teams full of innovative, eager software professionals to build the products that will transform our industry.

This is a dual-stack role for a hands-on senior engineer who can move comfortably between our .NET microservices platform and Java-based integration work for our marketing/content technology stack, building both backend services and the front ends that sit on top of them. It suits an engineer who genuinely maintains both skill sets, not someone primarily strong in one who has touched the other.

If you want to make a difference in the lives of students and teachers and understand what it takes to deliver high quality software, we would love to talk to you about this opportunity.

• You'll initiate and manage code reviews across both codebases; help keep engineering standards consistent regardless of which stack a piece of work touches
• You'll make pragmatic calls on which stack a new capability should live in, in consultation with engineering leadership
• You'll mentor other engineers and contribute to architecture decisions spanning both ecosystems
• You'll work collaboratively within a cross-functional, agile development team to solve problems, transfer knowledge and contribute to overall product architecture

• Experience with Database and Caching technologies such as MySQL/SQL Server, MongoDB, Elasticsearch, and Redis
• Experience in Test Driven Development and automated testing tools (NUnit/JUnit, Selenium, Cucumber, SonarQube)

Good to Have
