Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Cloud & Security IT Engineer - **Company:** Kalray - **Location:** Montbonnot-Saint-Martin, France - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Microsoft Windows, Active Directory, Artificial Intelligence, Apple Mac Systems, Backup Devices, Linux, Security Information and Event Management, Virtualization Technology, Data Logging, Okta, Information Technology, Hardware Acceleration, Commvault - **Published:** August 28, 2026 - **Apply:** https://www.kalrayinc.com/jobs/cloud-security-it-engineer/ ## About the Role * Real hands-on experience administering Microsoft 365 in a business environment - this is the heart of the role. * Practical command of security engineering: hardening, access control, patching, endpoint protection - you've configured these things, not just specified them. * Experience contributing to a security or compliance program (ISO 27001, NIS2, SOC 2, or similar), where you implemented the controls yourself rather than only tracking them. * Comfort working across a mixed fleet of Windows, macOS, and Linux systems. Nice to have: * Linux environments and infrastructure. * Identity providers such as Okta, Entra ID, or Active Directory. * Enterprise backup tooling (we use Commvault), endpoint management, or SIEM/EDR platforms. * An interest in AI tools and how to deploy them safely across an organization. * Certifications such as MS-102, SC-300, or SC-400 - welcome, but no substitute for practical experience., * Bachelor's to master's degree (Bac+3 to 5) in computer science or a related field. * 5+ years of experience in IT, ideally as the reference owner of a Microsoft 365 environment rather than one contributor among several. * Technical English required, alongside French for day-to-day work. * A builder's mindset: you'd rather fix something than raise a ticket about it. * A genuine security instinct - you notice weak configurations and fix them without being asked. * Autonomy, rigor, and pragmatism: our engineers are demanding users, and the best security measure is the one people actually accept. * Clear communication with technical and non-technical colleagues alike. ## Description You will join our IT team - five people including you - which handles both the build and the run of our entire infrastructure, over 300 machines across a genuinely varied environment. It's a small, enthusiastic team where everyone has real ownership of their subjects. As a Cloud & Security IT Engineer, you will own our Microsoft 365 environment and drive our security and compliance practices forward. There is real room to grow how we use the platform, so you'll have a genuine say in what we deploy and how we structure it. Your main responsibilities will include: Own our Microsoft 365 platform * Take end-to-end ownership of our tenant - administration, configuration, governance, and day-to-day reliability. * Expand the platform's reach: information protection, device management, collaboration governance, and more. * Keep our licensing rational and our costs under control. Strengthen our security and compliance foundation (ISO 27001, NIS2) * Put in place the tooling that keeps our fleet patched, monitored, and consistently configured - including endpoint protection, where you'll have a real say in what we choose. * Harden our environments against recognized security baselines and drive remediation of the gaps you find. * Translate framework requirements into technical controls - access control, logging, encryption, backup verification - and implement them yourself. This is a hands-on role: expect to spend most of your time building, not coordinating. * Act as our technical point of contact for internal reviews and external audits. Share in keeping our infrastructure running * Take part in our rotating "watchman" duty - roughly one to one and a half days a week per person - covering first-line support and daily operations. The rotation protects everyone's focus time for the rest of the week. * It's also hands-on exposure to the full breadth of our environment: Linux and Windows systems, virtualization, storage, networking. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Seriously gaming your cloud expertise: from cloud tourist to cloud native](https://www.wearedevelopers.com/videos/373-seriously-gaming-your-cloud-expertise-from-cloud-tourist-to-cloud-native) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [What makes Cybersecurity different for critical infrastructure?](https://www.wearedevelopers.com/videos/571-what-makes-cybersecurity-different-for-critical-infrastructure) - [We adopted DevOps and are Cloud-native, Now What?](https://www.wearedevelopers.com/videos/485-we-adopted-devops-and-are-cloud-native-now-what) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
