  • Collaborate & Lead: Work closely with product, UX, and engineering teams in Agile sprints, shaping platform capabilities and mentoring peers.
  • Champion Resilience: Participate in on-call rotations and incident response, driving proactive improvements for platform uptime and reliability.
  • Code with Excellence: Write clean, efficient, and maintainable code, and set the standard through thoughtful code reviews and technical leadership.
  • Drive Performance: Continuously optimize for speed and scale, refactoring and innovating as you go.
  • Document & Share: Ensure clarity and knowledge sharing by documenting architectures, processes, and best practices.

What You'll Bring:

  • Deep Java Expertise: Proven experience with Java 11+ and building scalable, distributed backend systems.
  • Frontend Acumen: Skilled in building robust, maintainable UIs with Angular or React.
  • Cloud & DevOps Savvy: Hands-on experience with AWS (IAM, S3, DynamoDB, VPC, ECS/EKS, SQS), Docker, Kubernetes, and CI/CD pipelines (Jenkins, Git, Terraform/CloudFormation).

  • Bonus Points: Experience leveraging AI tools to boost developer productivity.

What We Bring:

Join our GCI team to accelerate your career journey, working with cutting-edge technologies and contributing to projects that have real customer impact. You will be immersed in a dynamic environment that recognizes and celebrates your achievements.

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.
  • Drives innovation and creativity within and between teams.
  • Introduces employees to priorities outside of their immediate realm.
  • Ensures important interpersonal relationships and connections with one another and our community!

Belonging at Mimecast:

Cybersecurity is a community effort. That's why we're committed to building an inclusive, diverse community that celebrates and welcomes everyone – unless they're a cybercriminal, of course.

We're proud to be an Equal Opportunity and Affirmative Action Employer, and we'd encourage you to join us whatever your background. We particularly welcome applicants from traditionally underrepresented groups.

We consider everyone equally: your race, age, religion, sexual orientation, gender identity, ability, marital status, nationality, or any other protected characteristic won't affect your application.
