You’ll be the glue that holds things together—whether it’s coordinating timesheets, streamlining communications, or ensuring smooth day-to-day office operations. Your attention to detail and ability to juggle multiple responsibilities will be critical to your success.

Job description

• Manage employee data, including hours worked, overtime, holidays, and ensure timely payroll submissions.
• Collect and process engineer hours to ensure accurate payments via the finance department.
• Monitor and chase outstanding client invoices, maintaining professional communication and thorough records.
• Handle telephone enquiries, delivering a professional and friendly first impression every time.
• Use SystemPro to manage key administrative workflows (training can be provided).
• Coordinate internal communications between departments to support seamless operations.
• Maintain and update documents using Microsoft Word, Excel, and Outlook.
• Assist with ad-hoc projects, process improvements, and business development support as needed.

Key skills

• Excellent verbal and written communication skills, with confidence interacting across all business levels.
• Strong organisational skills with the ability to multitask, prioritise, and remain calm under pressure.
• Highly process-driven with a strong sense of initiative and accountability.
• Previous experience managing a busy switchboard or handling high-volume calls is desirable.
• A proactive team player who is equally comfortable working independently.
• Proficient in Microsoft Office (especially Excel and Outlook); knowledge of SystemPro is a bonus.
• Prior experience in a similar coordinator, office manager, or administrator role is highly advantageous.

What’s on offer?

• Join a fast-growing company with plenty of room for professional development.
• Be part of a close-knit, collaborative team that values your input.
• Work in a varied, hands-on role where no two days are the same.
• Onsite parking and regular working hours for excellent work-life balance.
