Senior Infrastructure Engineer

Randstad (Schweiz) AG; London; On-site; GBP 60,000 - 68,000; Full time

Job description

About the Company:

The Legal 500 Series is a market-leading directory renowned for its extensive analysis, rankings, and detailed editorial on the top global business law firms. We are committed to delivering high-quality content and insights to our audience, helping them make informed decisions.

Role Overview:
We’re hiring a Senior Infrastructure Engineer on a 12-month Fixed Term Contract to support delivery across our on-prem and cloud environments. This role is delivery-focused — it’s about getting things done, not growing into leadership.

The role supports a longer-term team development plan internally. We're looking for the person we bring in to enable that development plan, not compete with it.

Key Role Objectives:

1. Execute hands-on infrastructure work across BAU and project streams
2. Deliver project outcomes with minimal oversight
3. Provide knowledge transfer and technical mentoring by example (not formal coaching)
4. Support existing infrastructure while helping us modernise and improve operational efficiency

Technical Profile:
Our ideal candidate is someone strong across the following areas:

1. Hybrid environments: Hyper-V, Windows Server, local storage
2. Networking: SonicWall firewalls (HA pair), VPN, general routing/switching fundamentals
3. Cloud: Microsoft Azure (including basic automation), Intune, Teams migrations
4. Telephony: Exposure to SIP-based systems (Avaya ideal, but not essential)
5. Scripting: PowerShell — ideally someone who documents their work and can tidy or refactor existing scripts

Bonus: Any experience with transitions (on-prem to cloud), modernising infra, or cleanup/consolidation work.

Working Style / Expectations:

1. Adaptable, dependable, and delivery-oriented.
2. Someone who can jump in, get on with the work, and flex as priorities shift.
3. Not chasing progression or trying to embed permanently — this is not a stepping stone into a longer-term leadership role.
4. Happy working solo or alongside others — a balance of independent ownership and being a good team player.
5. Comfortable engaging with people outside the IT team in a personable, clear, and collaborative way.

This is a skilled delivery role with a clear purpose and an end date — and the right person will thrive in that clarity.
