Join Opsora

Senior Microsoft 365 System Engineer (m/f/d)

Opsora keeps Microsoft 365 environments secure, well-governed, and audit-ready for European mid-market companies (roughly 100 to 1,500 users). We are senior-led: the architect who scopes the work is the one who delivers it. Every engagement has clear phases, a documented handover, and a client team that can run the environment afterward. No retainers, no artificial dependency.

We are growing the senior delivery team to take on more high-stakes projects. You will own most of the hands-on delivery.

The role

This is project work, not operations - no daily ticket queue, no 1st level support, no on-call. You take projects end to end and hand over documentation a client team can run from. Typical work:

• Carve-outs and migrations: tenant-to-tenant, on-prem to cloud, and Active Directory to Entra ID, often under tight deadlines and across borders.
• Zero Trust: identity, Conditional Access, Entra Private/Internet Access, device compliance, and segmentation.
• AI readiness: data classification, oversharing remediation, and the governance that makes AI tools - Microsoft Copilot, Langdock, and others - safe to roll out.
• Governance and hardening: tenant security baselines, DLP, retention, and NIS2 compliance work.

You configure and harden Entra ID, Intune, Exchange Online, SharePoint, Teams, Defender, and Purview - with the judgment to know what a change affects before you make it - and you run the client workshops and calls that scope the work.

What you bring

• Deep, hands-on Microsoft 365 experience across multiple workloads - you can harden a full tenant safely
• Strong grasp of identity (Entra ID), security, compliance, and migration tooling
• The judgment to own outcomes and work with little oversight
• Curiosity and fast learning - we care more about how you think and adapt than about a fixed list of tools
• Clear written and spoken English; you can explain a decision to a client and stand behind it (German is a strong plus for our DACH clients)
• Microsoft certifications are welcome (for example MS-102, SC-300, SC-401)

How we work

• AI, used with judgment. We use AI deliberately to work faster - never where it risks client data or governance.
• Proven tools, current expertise. We keep our skills current and choose tools clients can rely on, not whatever is newest.
• Customer value first. We never sell or build something that does not fit the client's real needs, and we put their outcome ahead of billing more hours.
• Open and honest. We communicate clearly about issues, risks, and trade-offs.
• Built to last. We build long-term, trust-based relationships and leave clients able to run what we deliver on their own.

What we offer

• A permanent, full-time employee role - fully remote, project-based work with no travel, no helpdesk, and no on-call
• Real ownership of high-stakes projects across European clients
• Direct collaboration with an experienced founder-architect you can learn from
• A clear, transparent growth path with defined milestones and competitive compensation
