At Craster, we create intelligent design solutions that help premium hospitality brands deliver exceptional customer experiences.

This role sits at the heart of the business, supporting both people operations and day‑to‑day office administration, whilst also playing a key role in helping us modernise and automate how we work.

This is not a traditional admin role. We are looking for someone who is naturally curious about technology, enjoys improving processes, and is excited by the opportunity to use AI tools, workflow automation and systems to create smarter, more efficient ways of working across HR and office operations.

The successful candidate will support core HR administration, onboarding, HR systems management, office coordination and internal events, whilst also identifying opportunities to reduce manual administration through automation and process improvement initiatives.

• Producing regular management information and reporting
• Maintaining GDPR compliant electronic and paper‑based filing systems
• Supporting LMS and health & safety administration
• Identifying and implementing opportunities to automate manual HR and administrative processes using AI tools and workflow platforms
• Supporting internal engagement initiatives and company events

Office Administration

• Booking travel, meetings and accommodation as required
• Supporting logistics for trade shows and company events
• Ordering office supplies, catering and consumables
• Managing office access, key fobs and visitor coordination
• Liaising with building management and external suppliers
• Organising meetings and company events
• Managing post, deliveries and general office coordination
• Supporting office upkeep and environment management
• Assisting with IT asset tracking and licensing audits
• Providing basic WiFi and office technology support

What We’re Looking For

• Strong administrative and organisational skills with excellent attention to detail
• A positive, proactive and approachable attitude
• Excellent communication skills, both written and verbal
• Ability to work independently and handle changing priorities
• Strong problem‑solving skills and practical thinking
• Experience using HRIS platforms such as PeopleHR, BambooHR, Personio or similar
• Confidence using Microsoft 365 tools including Outlook, Excel, Word and Teams
• Genuine interest in AI, automation and process improvement
• Curiosity around technology and willingness to experiment with new tools
• Understanding of HR processes and administration
• Previous HR administration experience and/or HR related qualification preferred

Experience with tools such as Power Automate, Zapier or similar workflow automation platforms would be highly advantageous.

The person who will thrive in this role is someone who enjoys finding smarter ways to work, brings energy and initiative to improving processes, and enjoys supporting people across the business in a fast‑moving environment.

Our Values

• We care
• Be Curious
• Do the right thing
• Deliver Excellence
• Open to challenge

If this sounds like the kind of environment and opportunity you would enjoy, we would love to hear from you.
