What is an infrastructure engineer?
Infrastructure Engineers design, build, manage and support the IT infrastructure that underpin all internal user services and services to the public. Within the Infrastructure Engineer job family, there are many roles with specific skills and capabilities relevant to particular areas of expertise. Specialist roles include:
- Network Engineer
- Cloud Engineer
- Data Centre Specialist/Engineer
- Unix Engineer
- Wintel Engineer
- Ops Centre
- 3rd Line Build Engineer
- Platform Shift Engineer
- Telecoms Engineer
- Security Operations Centre
- Technical Infrastructure Engineer
As a member of the IE family, you’ll use your understanding of IT equipment and how components interact to make ensure the systems meet the user’s needs. This could mean delivering compute capacity to meet peak business demand, making it possible for multiple locations to access files on a server, or making sure crucial data is backed up regularly.
Why are Infrastructure Engineers so valuable?
They have a breadth of knowledge across multiple areas. While some may have deep expertise in particular areas, it’s their understanding of multiple disciplines that make them so valuable to an organisation.
What do Infrastructure do and not do?
The Infrastructure Engineer is an IT professional that:

- DOES communicate to business people, application owners, and customers in plain English while keeping their needs and the needs of IT in mind
- and probably does have multiple certifications across various brands and pieces that make up the infrastructure (MCITP, VCP, CCNP, and more).
