Job description
Senior Software Engineer – Storage

We build, we store, we scale!

Our customers rely on us to keep their data safe and secure which requires a massively distributed storage system that is resilient, scalable and highly performant. We combine both proprietary and existing storage technologies in both private and public cloud, to ensure we can serve and preserve petabytes of data in a fast and durable way.

Why Join Our Team?

“It’s an exciting time to join us as we embark on a journey to modernise how we manage petabytes of customer data in a hybrid cloud world” – Hiring Manager

What You’ll Do

As a Senior Software Engineer in the Storage team, you will play a pivotal role in designing, developing, and maintaining scalable storage systems. Your responsibilities will include:
• Design and implement scalable and reliable services utilising a combination of private and public cloud (AWS) infrastructure.
• Continue to optimise and evolve our existing Storage services.
• Mentor and guide other engineers, fostering a culture of collaboration, continuous learning, and professional growth.
• Create and maintain comprehensive technical documentation for architectures, processes, and procedures.
• Provide support during critical incidents and implement preventive measures.
• Monitor and analyze AWS usage, providing recommendations for cost savings without compromising system performance and reliability.
• Craft resilient, secure, and efficient code, ensuring optimal performance and minimal downtime.

What You’ll Bring
• Demonstratable ability to work effectively in a collaborative team environment, mentoring junior team members and contributing to a positive team culture.
• Demonstratable expertise in Java development, with a strong command of Java 11 and above.
• Proven experience in designing, developing, and optimizing backend systems for data processing at scale within AWS.
• In-depth knowledge and hands-on experience with foundational AWS services, such as; ALB, ECS, S3, EFS, ElastiCache, IAM, CloudWatch.
• Strong skills in Infrastructure as Code (IaC) tools, such as Terraform or AWS CloudFormation.
• Hands-on experience with Jenkins and establishing robust CI/CD pipelines.

What We Bring

Join our Storage team to accelerate your career journey, working with a large-scale distributed platform that underpins many of Mimecasts products. 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!

We believe in ‘growth that’s good’, we have ‘a culture that cares’ and we are on a ‘mission that matters’.

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!

DEI Statement

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, ****** orientation, gender identity, ability, marital status, nationality, or any other protected characteristic won’t affect your application.

Due to certain obligations to our customers, an offer of employment will be subject to your successful completion of applicable background checks, conducted in accordance with local law.
