About the role

Head of Enterprise IT

We are hiring a Head of Enterprise IT for our client — a fast-growing tech company expanding from its existing cloud/gaming infrastructure business into a large-scale AI data center build in Poland, with its first 50MW+ phase going live this year.

ROLE DESCRIPTION

The Head of Enterprise IT will own and build from the ground up the company's internal IT infrastructure — the systems, networks, and tools that run the business itself, separate from the customer-facing production platform. There is currently no dedicated internal Enterprise IT team in place for this project; this role is expected to establish the function and the team (sysadmins, network engineers, security specialists) essentially from zero. This role ensures employees across all offices and locations have secure, reliable access to corporate systems and hardware, manages the Enterprise IT budget and vendor relationships, and coordinates with the CTO where corporate systems intersect with the production platform (e.g., billing, monitoring).

RESPONSIBILITIES

• Build and own the internal company IT infrastructure from scratch (not the customer-facing production stack)

• Establish IAM, network security, and VPN infrastructure for a distributed, multi-office organization

• Set up office networks, employee access, and corporate hardware/software provisioning

• Build and scale a helpdesk/IT support function to serve all offices/locations

• Own security policies for internal systems (separate from production DC security)

• Manage the Enterprise IT budget and vendor/SaaS relationships from the ground up

• Ensure GDPR compliance and internal data protection controls

• Coordinate with the CTO on integration between corporate systems and the production platform (e.g., billing, monitoring)

• Where relevant, oversee corporate systems such as ERP, CRM, HRMS, and collaboration tools (Slack/Google Workspace/Jira)

MUST-HAVE

• 3+ years of experience in IT management, with 3+ years in a leadership/Head of IT role

• Demonstrated experience building an IT function/infrastructure from scratch (greenfield site, new company, new office, or major infrastructure re-platform) — not only maintaining an already-established environment

• Hands-on experience with IAM, network security, and VPN infrastructure

• Experience managing IT operations across multiple offices/locations

• Experience managing IT budgets and vendor/SaaS contract negotiations

• Working knowledge of GDPR and internal data compliance requirements

• Experience building or scaling a helpdesk/support function

• English proficiency sufficient for international vendor and stakeholder communication

NICE-TO-HAVE

• Experience managing enterprise systems (ERP, CRM, HRMS) end-to-end

• Experience in a fast-scaling company environment

• Familiarity with integrating corporate systems with production/billing platforms

• Relevant certifications (e.g., ITIL, ISO 27001, CISSP, CompTIA Security+)

• Experience supporting distributed/international teams (Poland/Ukraine/EU)

• Polish and/or Ukrainian language skills
