  • Experience with testing frameworks
  • Demonstrate discipline and rigor necessary to deliver critical features
  • Familiarity with continuous integration and deployment concepts

Mimecast offers formal and 'on the job' learning opportunities, maintains a comprehensive benefits package that helps our employees and their family members to sustain a healthy lifestyle, and importantly - working in cross functional teams to build your knowledge!

Our Hybrid Model: We provide you with the flexibility to live balanced, healthy lives through our hybrid working model that champions both collaborative teamwork and individual flexibility. Employees are expected to come to the office at least two days per week, because working together in person:

  • Fosters a culture of collaboration, communication, performance, and learning

  • Introduces employees to priorities outside of their immediate realm
  • Ensures important interpersonal relationships and connections with one another and our community!
