The Role

As Head of Operations, you’ll take ownership of the entire global operations function from demand planning and procurement to inventory and logistics.

• Build and improve core processes to enable scale and operational efficiency
• Collaborate cross-functionally with Sales, Product, Finance, and external partners
• Identify and resolve operational bottlenecks with speed and ownership
• Own supplier relationships, COGS oversight, and core operational reporting to support margin and efficiency targets

What We’re Looking For

• 3-5+ years of experience in operations within a CPG, DTC, or physical product business
• Hands-on experience managing supply chain, forecasting, inventory, and logistics
• Strong systems thinking; comfortable with spreadsheets and early tooling
• Proven ability to work independently, take ownership, and move fast
• UK-based, with the ability to travel to our Cardiff HQ as needed
• Bonus: Experience implementing an IMS or ERP system

What You’ll Get

• £50,000 - £65,000 salary (based on experience)
• Stock options package
• Flexible, hybrid working setup
• Full ownership of a core function in a scaling business
• Opportunity to make a visible impact and grow with the company
