About us

Hiyv supports enterprise customers and internal teams across AI, cloud, security, software engineering, digital platforms, infrastructure and data resilience. Hiyv helps organisations scale modern technology operations through secure, compliant and reliable delivery models that combine AI-enabled operations, cloud engineering, platform expertise, and scalable backend execution. The focus is not simply on speed, but on helping customers innovate while maintaining operational control, security, resilience, and sovereignty across increasingly complex technology environments.

The Role

We are consolidating two operating companies into a single greenfield Microsoft 365 tenant. The high-level design is being drafted now. We are looking for the project manager who turns that design into a delivered migration.

The technical content is owned by our lead architect, supported by an identity specialist, both in the CIO team. You are not the designer and you do not direct their technical work. You own the project: the plan, the sequencing, the dependencies, the risks and the delivery. When the plan and reality diverge, you are the one who sees it first and says so.

What you will do

There is no project structure in place yet - you build it. Planning, reporting cadence, tooling, decision log, the working rhythm across the team. Within your first weeks we expect a migration plan with waves, dependencies and cutover windows, derived from the HLD together with the architect.

Both organisations are Microsoft partners, which makes this more than a standard corporate migration. Delegated customer access, GDAP relationships, Partner Center and admin-on-behalf-of all move with the tenant, and getting the sequencing wrong there affects customer environments rather than our own users. Company rebranding is coupled to this migration as well: domain names, mail addresses and tenant branding are part of the scope, not a separate project.

You are also not the only thing happening. ERP and ITSM implementations run in parallel and share both the application landscape and the same people. Part of your job is keeping those dependencies visible and sequenced rather than discovering them late.

The delivery team does not exist yet either. Domain specialists will be recruited in Sofia once the HLD defines what is needed, and you help shape those roles and select the people. The CIO supports you in this.

From there you run it. You track progress against plan and escalate early rather than late.

You keep the interfaces aligned: architecture, identity, security, application owners, the Dutch service desk and workplace teams, and external vendors. You plan the pilot, the waves, the cutover weekends and hypercare - local execution in the Netherlands is delivered by Dutch colleagues whom you coordinate but do not manage. When you conclude that we need more capacity, you make the case and we decide it together.

You produce a weekly progress report a director can read in five minutes, and a risk log that changes what people do.

What you must have done

Led at least one Microsoft 365 tenant migration, or a comparable large-scale cloud or workplace migration, as the project manager from planning through cutover. You have run wave-based user migrations and know what tends to break.

You do not need to be an engineer, but you must be technically literate enough to run this without translation. You understand what Entra ID, Exchange Online, SharePoint and OneDrive, Teams and Intune contribute to a migration, what the sequencing constraints between them are, and what migration tooling does. You can read an architecture document, spot where the plan is thin, and challenge an estimate.

Experience setting up a project from scratch, rather than stepping into a running one, is essential. Experience with Microsoft partner tenants - GDAP, Partner Center, delegated administration is a strong advantage. Post-merger integration experience is welcome but not required.

How you work

You check things yourself rather than asking for a status. You work remotely and still get people in another country to do what the plan says - by being specific, following up, and being right often enough that people stop arguing. You are comfortable with the ambiguity of a project whose team is still being hired.

English is the working language. Occasional travel to the Netherlands around cutover milestones.
