  • Knowledge of software design patterns and architecture
  • Ability to use different techniques to diagnose and fix software problems
  • Experience collaborating with other engineers

Other factors we look for (the more the merrier here):

  • Experience in one of our core languages (C#, Node.js, React.js, or PHP)
  • Experience running services in both Linux and Windows environments
  • Ability to architect and manage distributed data environments
  • Knowledge of micro-service architectures (e.g. the Netflix OSS stack)
  • Experience using distributed caching, NoSQL data stores, and Big Data analytics tools
  • Web development experience that involved JavaScript, CSS, or Node.js
  • Experience building REST APIs with JSON messages
  • Ninja-like skills in working with OLTP databases
  • Ability to read and optimize SQL query plans
  • Ability to read and write SQL stored procedures
  • Knowledge of networking protocols, infrastructure, etc.
  • Experience with performance monitoring tools and dashboards (e.g. StatsD, InfluxDB, Grafana, etc.)

  • Excitement about introducing the team to new tools, languages, or concepts that will help make our team and our product better
