Job description

About the Role

We’re looking for a commercially minded Head of Marketing to lead the development of a scalable, measurable marketing engine that drives mid‑market and enterprise pipeline growth, supports customer expansion and retention, and drives revenue operations, reporting, and attribution.

This is a hands‑on role for a senior B2B marketer who’s as comfortable shaping strategy as they are rolling up their sleeves to deliver in an entrepreneurial environment. You’ll work closely with the wider Commercial team to keep everything aligned to our growth goals.

You’ll own a clear pipeline and revenue contribution target and be a key member of the revenue leadership team responsible for overall company performance. You’ll also lead a small team across content, demand generation, and product marketing, with the opportunity to develop and shape the function as the business scales.

• Own the end‑to‑end marketing strategy and execution to drive sustained revenue growth
• Operationalise positioning and messaging framework across all marketing communications, channels, campaigns, and go‑to‑market activity
• Own marketing budget management, ensuring efficient allocation of spend and a strong focus on ROI across all marketing activities
• Drive mid‑market and enterprise pipeline growth by developing and executing a sophisticated Account‑Based Marketing (ABM) strategy
• Design and execute programmes that generate predictable, measurable pipeline in close partnership with AMs and AEs.
• Develop and optimise a diversified channel mix across inbound, outbound support, partnerships, and campaigns, prioritising scalable, cost‑effective pipeline generation aligned with target payback periods

Customer Expansion & Retention

• Own marketing’s contribution to Net Revenue Retention (NRR), Gross Revenue Retention (GRR), and churn reduction
• Support and develop customer lifecycle programmes from onboarding through to adoption and expansion to drive product adoption
• Partner closely with Account Management, Customer Success, and Support to identify and engage at‑risk customers

Product Marketing

• Optimise product marketing foundations, including ICP definition, positioning, messaging architecture, and competitive intelligence
• Own competitive intelligence, including the development of battle cards, win–loss analysis, and ongoing market insights to strengthen commercial strategy
• Enable sales and customer‑facing teams with high‑impact product marketing assets
• Lead, coach, and develop the marketing team
• Build a culture of accountability, experimentation, and high execution standards
• Identify future hiring needs as the business grows

Revenue Operations & Reporting

• Owns marketing attribution and performance measurement
• Partner closely with commercial leadership and the Revenue Operations department to improve data hygiene, reporting structures and forecasting accuracy across the revenue engine
• Ensure marketing activities are clearly tied to pipeline and revenue outcomes

Success Measures (KPIs)

• 4–5x marketing‑generated pipeline coverage against revenue targets
• Measurable contribution to Net Revenue Retention (NRR) and Gross Revenue Retention (GRR)

About You

We’re open to candidates who come from either a demand generation or product marketing background, as long as you’re commercially well‑rounded.

You’ve previously worked as a Head of Marketing or Marketing Director in a fast‑paced, high‑growth B2B startup environment, with experience targeting mid‑market and enterprise customers. You’re comfortable owning revenue‑linked KPIs and know how to measure success in a meaningful way. You’ve managed and developed marketing teams, and you’re equally at ease setting strategy and getting hands‑on when needed. You’re also familiar with modern marketing tech stacks, particularly HubSpot and Salesforce.

Experience in the pharmaceutical, biotechnology, or scientific software space would be a bonus
