Marketing Manager in London

Black Bull Biochar (BBB) is a growing UK company scaling the use of biochar, a carbon-rich material that improves soil health and removes carbon from the atmosphere. The company is entering an exciting expansion phase, growing its presence across Edinburgh, London, and Manchester, and building a team that will define the future of agriculture, renewable energy and carbon removal.

We are looking for someone to build the BBB Marketing Strategy, someone who cares deeply about agriculture, climate, and the people working within it. This is a hands-on role where you will shape how BBB tells its story, how farmers and partners engage with our work, and how we build credibility across agri-tech and climate-tech communities.

You will work across digital channels, field-based activity, events, case studies, and partner engagement to build a consistent, trustworthy brand. You’ll collaborate with agronomists, operations, sales and leadership to turn technical information into simple, accessible and human-centred communication.

This role suits someone who enjoys being creative, who values practicality over polish, and who understands that trust in agriculture is built through clarity, consistency and respect.

• Develop and execute BBB’s marketing strategy across digital, field and partner channels
• Create clear, engaging content: case studies, videos, newsletters, presentations, blogs, and product explainers
• Build BBB’s brand presence within agriculture, carbon removal, and climate innovation sectors
• Work with the founders, the agronomy team and sales to produce farmer-focused educational materials
• Manage website updates, social content, email campaigns and analytics
• Support the planning and delivery of events, farm days, trade shows and partner workshops
• Gather insights from farmers, partners and internal teams to shape content and campaigns
• Track performance and share insights to help refine future marketing activity
• Represent BBB externally and build relationships with relevant networks and industry groups

• A collaborator: Works well across teams; comfortable taking feedback and crediting others
• A creator: Comfortable conjuring and moving from ideas to execution quickly
• A communicator: Clear writing, simple messaging, and an ability to remove jargon
• 5+ years in marketing, ideally in agri-tech, sustainability or technical sectors
• Curious about agriculture and climate, and willing to learn technical concepts
• Observant and empathetic, understanding farmers’ needs, pressures and communication preferences
• Comfortable with ambiguity, able to adapt when priorities shift
• Positive and proactive, bringing energy and thoughtfulness to day-to-day work

• A cross-cutting hands-on experience working in a purposeful, impact-driven, fast-paced start-up at the frontier of climate tech innovation.
• The chance to grow and shape an organisation in its early stages.
• Health insurance including dental, optical and mental health cover.
• 25 days annual leave a year, not including bank holidays and the ability to remote work permanently for two weeks a year, and the option to buy back up to 5 days of annual leave.
• Building a greener future where your work removes carbon, restores soil health, decarbonises energy and creates a lasting positive impact for generations to come.
