1st Line IT Support Technician
Department: Operations
Employment Type: Full Time
Location: Plymouth
Description
Plessey is growing fast, and our IT team needs to scale with it. We’re looking for a 1st Line IT Infrastructure Support Technician to be the primary point of contact for day-to-day IT support across the business.
This is first and foremost a 1st line role, with a genuine, structured progression path into 2nd line and, ultimately, 3rd line or specialist infrastructure work as you build your skills and experience.
You’ll own the day-to-day ticket volume, covering account issues, device setup, and software and hardware problems, while freeing the wider team to focus on infrastructure and project work. As you develop, you’ll take on more complex 2nd line diagnostics, with a clear route towards 3rd line and project-focused work.
Based on-site at our manufacturing facility, you’ll work closely with production, engineering and business stakeholders across the FAB. IT supports both standard office systems and equipment on the production floor, so you’ll need to understand how downtime and access constraints in a manufacturing environment differ from a typical office setting. You’ll also support other Plessey offices remotely, with occasional travel where on-site support is needed.
You’ll need good working knowledge of the Microsoft ecosystem, along with the tools and systems that underpin day-to-day IT support. You’ll also play an active role in maintaining accurate IT asset records and be a visible, stakeholder-facing presence for IT across the business.
