  • 5+ years of proven experience as a software engineer, with some familiarity in coding both web applications and backend services.

  • Solid understanding of the client/server technology stack (HTTP, REST, compression, serialization, error handling, mobile), as well as API, distributed systems, and service architecture design

  • Model of software engineering best practices, including practical agile development, unit testing, code reviews, design documentation, debugging, and problem solving.

Company Description

Twitter is what’s happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right (not what's easy) to serve the public conversation.

The mission of our Core Services group is to provide the platform that enables rapid product development at Twitter scale through powerful generic building blocks, flexible abstractions, and self-service tooling. The Core API team provides a GraphQL service for our Twitter clients, and wants to make it easy to add data to and manage the backing schema. We build API management tools that abstract this complexity and help other developers throughout the company go faster and be happier.

We believe in the power of a distributed team. We use Google Docs, video chat, and Slack to communicate and work together across many time zones.
