Why Join Our Team?

“ If you’re passionate about building and maintaining reliable, scalable, and secure platforms that support software integration and deployment, our Build team is for you. We manage complex build processes and infrastructure that enable hundreds of developers globally to deliver software quickly, automatically, and compliantly at scale.” – Hiring Manager

What You\’ll Do:

• Manage and improve the whole lifecycle for build services — from design, through deployment, operation, and optimisation.
• Support rollout of new features, upgrades, processes, and new technologies.
• Collaborate with software engineering teams, providing support on build issues, configuration, and artefact deployment.
• Scale and evolve systems with automation, and push for changes that improve reliability and velocity.
• Take part in disaster recovery testing, incident resolution, capacity planning, monitoring, and maintenance to ensure high availability of build-related systems.
• Plan and deliver on-premises build migrations to AWS (cloud migration planning, infrastructure assessment, design, configuration and optimisation, testing & validation, documentation).
• Take ownership of build tools and processes, ensuring adherence to recognised best practices.
• Support Atlassian products like Jira, Confluence, and Jira Service Management.
• Utilise Jenkins for continuous integration and delivery, ensuring secure and reliable build pipelines.
• Work extensively with container technologies (e.g., Docker, Kubernetes) to enhance scalability, governance, and compliance in our development and deployment processes.
• Integrate and manage Source Control Management (SCM) tools such as Git, Bitbucket, or GitHub, ensuring robust version control and traceability throughout the software lifecycle.
• Implement and maintain governance and compliance standards within build and deployment pipelines, including auditing, policy enforcement, and security best practices.

Who you are:

• A valued team player in a dynamic, autonomous, multi-functional agile team.
• Experienced in designing, analysing, and optimising large-scale build systems.
• Proven track record delivering solutions that are functional, secure, scalable, and reliable.
• Strong technical knowledge and experience of Linux/Windows build systems, protocols, and standards. For example, Jenkins, GitLab, Nexus, SCA tools, Maven, Gradle, MS Build, etc.
• Skilled in managing distributed, high-performance services in Java, Python, or Ruby.
• Experienced in deploying and operating services on Linux-based infrastructure in the cloud.
• Familiar with container technologies — e.g., Docker, Kubernetes, Helm, etc.
• Systematic problem solver with effective communication skills; a self-driven team player who thrives in dynamic environments and adapts to complex changes.
• Strong scripting experience in at least one language.
• Experience with one or more configuration management tools like Puppet, Chef, Ansible, or SaltStack.
• Demonstrated experience in maintaining governance and compliance within CI/CD pipelines and containerised environments

What We Bring:

Join our 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!
