About Mustard HR

Mustard HR is a small but growing HR consultancy supporting a wide range of clients with clear, practical and human people solutions.

We’ve reached an exciting stage where we’re creating a brand new role to help run the business day to day and shape what comes next. This is not a rigid, boxed in position. It is a genuine opportunity to become a trusted partner within the business and make the role your own.

If you don’t tick every experience box but feel this role fits you, we actively encourage you to get in touch. Attitude, judgement and values matter more to us than a perfect CV.

About the role

We are looking for a confident, capable all‑rounder with a strong understanding of HR and or small service‑based businesses.

You will work closely with Lucy, Mustard’s Director, supporting the smooth running of the business, improving systems and processes, and helping deliver an excellent experience for clients and consultants alike.

Client and team coordination

• Prepare client proposals, contracts and onboarding documents
• Maintain confidential client and team records
• Coordinate client and team onboarding

• Organise team meetings, events and internal communications
• Support service continuity during holidays

Systems and projects

• Manage CRM, project management, HRIS and ATS systems
• Maintain clear processes and standard operating procedures
• Marketing coordination
• Support internal projects and service development

Future scope

This role has the scope to grow with the business and be shaped by the right person, including:

• Becoming a primary client contact
• Supporting work coordination across the team
• Involvement in invoicing and light financial administration

Who you are

• Location flexible. Norfolk or Suffolk preferred but not essential
• Comfortable working remotely with secure, reliable Wi Fi
• Confident contributing ideas and offering constructive challenge
• Happy working independently within a close knit team

Skills and attitude

• Excellent communication and organisation
• Strong attention to detail and sound judgement
• Confident administrator with good system capability
• Comfortable managing confidential information
• Proactive, trustworthy, warm and customer focused
• Keen to grow with the business

Benefits and perks

• Genuine flexibility around hours and working patterns
• Birthday day off in addition to annual leave
• Funded professional fees at our discretion

Why this role exists

We’re focused on balance, client experience and building a supported, engaged team.

We want Mustard to be the go-to consultancy for top‑quality, clear and relevant people solutions. Our ambitions include recognition as trusted, independent experts, known for practical employment law support, strong people practices and inclusive, collaborative partnerships.

This newly created role is central to making that happen.

If this role excites you, even if you do not meet every requirement, we would love to hear from you.
