Job description

Client introduction

Our client is a long-established professional services and business solutions group in Singapore. With more than 30 years in the market, they serve a broad client base across accounting, tax, advisory, payroll, corporate services and technology consulting. The firm holds recognised security and data accreditations (including ISO 27001 and a national Cyber Trust mark), so infrastructure standards and security posture sit at the centre of how they operate. They are now investing in IT capability and are looking for a hands‑on engineer to lead build and implementation work rather than keep‑the‑lights‑on support.

Job responsibilities

• Lead the design, build and implementation of Windows-based infrastructure from the ground up, including full tear‑down and rebuild of existing environments where required.
• Stand up and configure Windows Server environments, Active Directory, Group Policy, DNS/DHCP and related core services as part of new builds and migrations.
• Plan and execute server and infrastructure migrations, consolidations and refreshes, including cutover planning and rollback.
• Build and configure virtualisation and storage layers (for example VMware or Hyper‑V) as part of greenfield and rebuild projects.
• Implement and harden systems to meet the firm's security and compliance standards, including patching strategy, access controls and baseline configurations.
• Automate build, configuration and deployment tasks using scripting (for example PowerShell) to make environments repeatable and consistent.
• Produce build documentation, runbooks and as‑built records, and hand over stabilised environments to support teams.
• Work with internal stakeholders and vendors to scope requirements and deliver implementation projects on time.

Job requirements

• Around 6 or more years of hands‑on systems engineering experience, with a clear track record of implementation and build work (not primarily maintenance or service‑desk).
• Strong Windows Server engineering depth: Active Directory, Group Policy, DNS, DHCP, certificate services and related infrastructure.
• Backgrounds in systems integration, IT consulting or managed services are well‑suited to this role, given the breadth of hands‑on implementation exposure these environments provide.
• Demonstrable experience building environments from scratch and / or rebuilding existing ones, with examples you can talk through in detail.
• Solid virtualisation experience (VMware and / or Hyper‑V) and a working understanding of storage and networking fundamentals.
• Scripting and automation capability, ideally PowerShell, for repeatable deployments.
• Comfortable owning the engineering side of a project end to end, from design through to cutover and documentation.
• Exposure to Microsoft 365 / Azure and to security hardening or compliance‑driven environments is an advantage.

Why you should join them

• A genuine build mandate. This is an implementation‑led role where the work is designing and standing up infrastructure, not maintaining a static estate.
• Real project ownership, with the autonomy to make engineering decisions rather than follow a runbook written by someone else.
• A stable, well‑established firm with strong security and compliance accreditations, so good engineering practice is valued rather than cut.
• Broad technology exposure across a multi‑service business, with room to grow into infrastructure leadership.
