Software Engineer II

About the role

Mimecast was founded in 2003 with a mission to provide relentless protection against cyber threats. We serve tens of thousands of customers globally, offering a comprehensive suite of security solutions including brand protection, security awareness training, web security, compliance, and more. Our goal is to help organizations protect themselves from malicious activities, human errors, and technological failures.

Team You Will Join

A Product Engineering Squad within the Governance, Compliance & Insights (GCI) Pillar, where your ideas shape the product and your code ships regularly. You will work on features and services that help some of the world's largest enterprise customers govern, archive, and gain insight from their collaboration and email data.

What You'll Do

• Build and maintain full-stack features — from modern, containerized backend services to user-facing React interfaces — that power compliance and insights for enterprise collaboration and email data.
• Your primary focus is feature development: working across C# and Java codebases, contributing to the React frontend, and owning your work from design through production.
• Deploy and maintain services in Kubernetes-based environments, handling production incidents as part of an on-call rotation.
• Collaborate with SDETs to build high-quality, performant, scalable, and testable software.
• Participate actively in sprint refinement and estimation, bringing both technical context and genuine curiosity to the conversation.
• Work with SRE to follow their guidance on deployment practices, observability standards, and infrastructure conventions to ensure your services are production-ready.
• Use AI tooling as a standard part of your daily engineering workflow.

What You'll Bring

• Proficiency in one or more statically-typed, object-oriented languages — C#/.NET or Java strongly preferred.
• Solid experience with relational databases — schema design, migrations, and ORM patterns.
• Demonstrable, accountable use of AI — coding and reasoning tool use as a core part of your daily workflow (e.g. Cursor, Claude, or GitHub Copilot), applied to real work such as code authoring, debugging, documentation, and alert investigation.
• Familiarity with REST API design and microservices architecture.
• Enough React/TypeScript to contribute meaningfully to frontend work when a feature calls for it.
• Experience deploying or operating services in Kubernetes-based environments — at the consumer level, not the platform level.
• Comfortable with production ownership — on-call is part of the job, not someone else's problem.
• Participate actively in team ceremonies: refinement, estimation, retrospectives.
• Communicate clearly in writing — our teams are distributed, and async clarity matters.
• Comfortable saying "let's do this the right way" even when the shortcut is tempting.
• Ask for help when you need it and give it freely when others do.

Ways of Working

• Collaborate well on a cross-functional team of engineers, product, and UX designers.
• Have a bias for action and prefer shipping small, frequent improvements over big-bang changes.
• Be comfortable with production ownership — on-call is part of the job, not someone else's problem.
• Participate actively in team ceremonies: refinement, estimation, retrospectives.
• Communicate clearly in writing — our teams are distributed, and async clarity matters.
• Be comfortable saying "let's do this the right way" even when the shortcut is tempting.
• Ask for help when you need it and give it freely when others do.
