Head Roaster

Old Spike Roastery is a specialty coffee social enterprise based in South London. Every bag we sell funds meaningful employment and support for people experiencing homelessness. We roast and ship exceptional coffee every week to wholesale cafe accounts, offices, restaurants, and direct-to-consumer customers across the UK. We’re looking for a Head Roaster to lead the quality and coffee side of our roastery as we continue to grow.

The Role

This is a senior, hands-on role responsible for everything that goes into the cup, from sourcing and selecting green coffee through to roasting, quality control, and blend development. You’ll lead a small roasting team, manage our roasting schedule, and be the person who sets and maintains the quality standard across everything we roast. We’re currently roasting high volumes per week across wholesale, retail, and e‑commerce, and that volume is continuing to grow. We need someone who is comfortable operating at that scale without compromising on quality, and someone who understands that specialty quality and volume aren’t mutually exclusive. You must understand customer needs and preferences within the scope of specialty, and the importance of meeting those requirements. You’ll work closely with our Roastery Operations Manager, who handles the commercial and logistics side of the site, and with senior management on sourcing strategy, budgets, and new product development.

What You’ll Be Doing

• Roasting / Profiling: leading all production roasting on our Giesen W30A, creating, maintaining, and adapting roast profiles, ensuring consistency and quality across every batch.
• Green coffee sourcing and management: building and maintaining relationships with importers and traders, cupping and evaluating samples, selecting coffees that align with our quality and sustainability standards and commercial needs.
• Forecasting: building a sourcing schedule for all the Old Spike line based on future harvest and arrivals from different origins.

• Blend development: creating and refining our core blends and seasonal offerings ahead of time, working with the commercial team to ensure the range meets customer demand and margin targets.
• Budget and margin: managing the green coffee budget, understanding and tracking added costs, and calculating margin across our product range.
• Production planning: building and managing the weekly roasting schedule in line with order volumes, stock levels, and fulfilment deadlines.
• Team leadership: line managing the Production Roaster and any supporting roasting assistants; setting standards, running check‑ins, and developing the team’s skills and coffee knowledge.
• Equipment: owning the maintenance and care of the Giesen W30A and all roastery equipment.
• Coffee training: leading internal coffee education for the wider team, including baristas across our cafe sites.
• Marketing support: sourcing traceability and marketing material from importers for new releases.
• Client-facing and business development: attending client cuppings and tastings to support our sales and account management team.
• Industry representation: representing Old Spike at industry events, exhibitions, and competitions.
