Job description

Office Administrator

Central Services Team | Manchester Office

Hybrid / Flexible Working | Monthly travel to Liverpool required

Join a team where people really do come first.

At Walker Sime, we’re more than just a construction consultancy – we’re a team of friendly, dynamic, down-to-earth people who care deeply about what we do, how we do it, and the people we’re on the journey with.

We’re proud to be a people’s values-led business, focused on integrity, collaboration, and making a genuine impact. As we grow, we’re looking for an Office Administrator who’s just as passionate about people and keeping things running smoothly as we are.

Your Role in the Team

This isn’t your average admin role. You’ll be part of the glue that holds things together – a first friendly face people see, an organiser behind the scenes, and part of a team who makes the magic happen!

If you love variety, thrive on being organised, and enjoy getting stuck in to support a busy team, this could be the perfect role for you.

Your Day to Day -

Travel & Diary Support

• Booking travel (sometimes international)
• Coordinating diaries and setting up meetings
• Taking meeting minutes when needed
• Keeping signing-in sheets up to date

Reception & Office Vibes

• Answering calls and greeting visitors with a smile
• Making sure meeting rooms are prepped and presentable
• Sorting out catering when required (we do love a good sandwich platter)
• Occasional visits to other Walker Sime offices to provide on-site support

Admin & Office Support

• Owning the shared admin inbox and responding to queries
• General admin tasks – photocopying, filing, formatting docs
• Keeping kitchen and stationery supplies stocked
• Managing office and cleaning orders
• Updating credit card spreadsheets and chasing receipts
• Supporting teams and senior leaders with ad hoc requests
• Supporting our various service lines with admin/secretarial tasks
• Liaising with suppliers (printers, tech, etc.)
• Running occasional errands (Post Office run, anyone?)

New Starter & Onboarding Support

• Ordering IT and PPE for newbies
• Adding new starters to employee benefit systems
• Coordinating H&S inductions and onboarding meetings
• Supporting training roll-out for new starters
• Formatting CVs like a pro

Health, Safety & Wellbeing

• Managing maintenance visits (PAT testing, fire safety, etc.)
• Keeping noticeboards and H&S info fresh and up to date
• Helping with annual policy updates
• Supporting internal wellbeing campaigns and events (from step challenges to cake days – we like to keep things balanced!)

What We’re Looking For -

• Organised, unflappable, and ready to roll up your sleeves
• A great communicator with a warm, professional approach
• Detail-obsessed when it comes to documents and formatting
• Confident using Microsoft Office and tech tools
• Reliable, positive, and always up for helping other

The Walker Sime Promise

At Walker Sime, you’ll be part of a thriving business with a big heart. We’re proud to foster a welcoming, inclusive culture where you’re trusted, supported, and encouraged to be your authentic self.

• A genuinely people-focused culture
• Flexible, hybrid working options
• Opportunities to grow and take on new challenges
• Wellbeing support and regular team socials
• Modern offices in great locations
• A comprehensive benefits package
• A company that values you just as much as your to-do list

If colour-coded calendars, smooth-running offices, and a bit of team banter sound like your thing – we reckon you’ll fit right in!
