** Software Engineer II
**** About Mimecast
** Relentless protection. Resilient world. Mimecast was born in 2003 with a focus on delivering relentless protection. Each day, we take on cyber disruption for our tens of thousands of customers around the globe; always putting them first, and never giving up on tackling their biggest security challenges together. We continuously invest to thoughtfully integrate brand protection, security awareness training, web security, compliance, and other essential capabilities.

Mimecast is here to help protect large and small organizations from malicious activity, human error, and technology failure — and to lead the movement toward building a more resilient world.
** The Team
** You will join a product engineering squad within the Governance, Compliance & Insights (GCI) pillar — a team where your ideas shape the product and your code ships regularly, focused on building the features and services that help some of the worldʼs largest enterprise customers govern, archive, and gain insight from their collaboration and email data. We do a few things, and we do them at scale:
* Collaborate closely with product to continually add business value through feature development
* Show strong ownership of the full software development lifecycle alongside a team that trusts and supports each other
* Build and maintain services that process data at enterprise scale from email and collaboration platforms like Slack and Microsoft Teams
* Contribute to a culture of engineering excellence through code reviews, knowledge sharing, and continuously raising the bar for quality across the squad
* We hold a few beliefs about how that work should be done:
* Continuous deployment. Smaller chunks of work, shipped more frequently, with the safety rails to make that the default — not the exception.
* Builders own what they build. You own your features from design through production.
* Shipping is not the finish line — supporting what you ship is part of the job.
* Continuous learning is key. We learn from what we build and how we operate, using those lessons to streamline our processes and safeguards so we can move quickly and safely without repeating the same mistakes.
** AI-First Engineering at Mimecast
** Mimecast is an AI-First engineering organization. Our teams actively leverage AI-powered development tools across all facets of engineering, from code development to testing, documentation, and operations. We're looking for engineers who don't just use AI tools but champion their adoption and establish new ways of working.

Our AI leadership extends beyond how we build to what we build. Our Mihra AI agent delivers7x faster threat response for customers, and we're recognized as "Agents of Change" in Human Risk Management. Engineers here work at the intersection of cutting-edge AI tooling and AIpowered security products that protect organizations worldwide.
** The Role
** As a Software Engineer II in the GCI pillar, you will 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.

You will work in a small, focused, cross-functional squad in close partnership with product, and alongside our SRE team who will guide you on deployment, observability, and infrastructure best practices.
** What You'll Do:
*** Build and maintain backend services in C# (.NET) and Java — including evolving mature C# codebases and contributing to greenfield Java services
* Contribute to React frontend work to complete vertical slices of functionality end to end, carrying features from API to screen when the work requires it
* Write well-tested, observable code that integrates with shared dashboards and our platform's logging and tracing standards
* Work with relational databases —…
