Growth Marketing Lead

About Neutreeno

Climate change is the defining business challenge of our time, and we're here to solve it. Most decarbonisation solutions count emissions but do nothing to reduce them. We've changed that.

We’re Neutreeno, an emissions-to-performance platform, born out of the University of Cambridge's Department of Engineering. We help companies with supply chains and production processes turn emissions data into operational insight, the kind that cuts costs, sharpens decisions, and unlocks genuine competitive advantage. For operations and finance, it's margin they can measure. For sustainability teams, it's progress they can prove. Same data, two audiences, one engine.

We’re a fast-moving team that values EQ just as much as IQ. Autonomy, high-ownership, speed and no-ego collaboration are at our core. We seek people who care deeply and are eager to work on solving problems bigger than themselves.

The Role

At Neutreeno, marketing is the engine, and as our Growth Marketing Lead, you'll own the metrics, build the pipeline, and be accountable for connecting marketing to measurable business outcomes.

You'll lead marketing at Neutreeno and be fully accountable for pipeline. There's no marketing team under you, no agency on retainer, and no system to inherit. Your first 90 days are about shipping: measurement infrastructure, the content engine including CRM, and the first paid campaigns. The leadership team, working with our brand strategy partner, has defined a clear brand strategy and mapped the needs of the business. Your job is to build on this foundation and turn it into pipeline for our sales team.

This position operates on a hybrid work model with 3 days per week in our Cambridge office. Exceptional London-based candidates will be considered with a 2-day per week office requirement. Fully remote arrangements will be considered for outstanding international candidates, provided there is sufficient overlap with UK working hours.

The Work You’ll Do

• Ship a working attribution model and measurement dashboard in your first 30 days, so every conversation about marketing is grounded in data, not opinion.
• Own the weekly marketing performance and optimisation reports.
• Run 2 paid campaigns per quarter, end to end — strategy, creative brief, activation, optimisation, and post-mortem.
• Publish 2–3 pieces of long-form content per month that translate Neutreeno's science into the commercial language our buyers use.
• Build the case studies and customer stories that close deals — 3 finalised per quarter, more in active production.
• Land 3+ speaking slots, media placements, or podcast appearances per quarter.
• Own lifecycle marketing end-to-end — CRM, email, welcome sequences, nurture flows.
• Build the sales enablement kit — pitch deck, one-pagers, case studies.
• Shape, evolve, and articulate Neutreeno's vision, voice, and positioning across all channels, in partnership with the leadership team and our brand partners.
