Growth Marketing Lead in Cambridge

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 and be fully accountable for pipeline. There's no marketing team under you 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. Fully remote arrangements will be considered for outstanding candidates, provided there is sufficient overlap with UK working hours.

The Work You'll Do

• Oversee the build and rollout of a working attribution model and measurement dashboard
• Own the weekly marketing performance and optimisation reports
• Run paid campaigns each quarter, end to end: define a regular process for planning, execution, and retrospective analysis
• Publish long‑form content per month that translates Neutreeno's science into commercial language our buyers use
• Build case studies and customer stories that position our offering competitively and help us close deals
• Build a public relations framework that lands speaking slots, media placements, or podcast appearances each quarter
• Own lifecycle marketing end‑to‑end: inbound and outbound email, welcome sequences, nurture flows, all managed in our CRM
• Work with the BDR team to align top‑of‑funnel marketing activity with outbound sales, generating qualified volume for BDRs to convert
• Build and maintain our 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 leadership and brand partners

Minimum Qualifications

• Been the first or second marketing hire at a startup, not a contributor on a team
• 6+ years across the full marketing lifecycle at fast‑growing tech companies (B2B SaaS preferred), at least 2 in a startup environment where you built rather than maintained
• Proven track record of connecting marketing efforts to MQL generation and revenue
• Prefer shipping over planning; produce v1 quickly and iterate
• Strong writing skills; copy that does strategic work for a challenger brand
• Daily use of AI tools to compress production timelines without compromising quality
• Ability to translate complex technical ideas into narratives for technical and non‑technical audiences
• Comfortable working closely with company leadership, serving as a thought partner in direction and positioning

Preferred Qualifications

• Experience in sustainability or climate sector
• Marketing technical products to non‑technical buyers (operations, finance, procurement)
• Proficiency in design tools such as Figma

Benefits

• £60,000 - £80,000 base pay
• 25 days annual leave
• Year‑end performance bonus
• Meaningful equity stake
• Company pension with NEST
• Leading private health insurance
• Cycle‑to‑work scheme

Work Environment

• Remote working allowance for personal travel, plus 2 weeks holiday per year
• Work from Neutreeno HQ at the Cambridge Institute for Sustainability Leadership
• On‑site amenities: unlimited free coffee, regular events with global sustainability leaders

Culture & Growth

• Fast‑growing team (200%+ YoY growth) from diverse backgrounds, recently closed a $5M seed round
• An open‑minded culture with flat hierarchy where ideas and ownership matter
• Chance to work alongside world‑class climate scientists and engineers
