Role Overview

Cambridge Spark is building a modern B2B marketing function to match an ambitious new direction: helping large, complex organisations build the capability to adopt AI and prove the results. We're investing in editorial, research, video, community and events to earn the attention and trust of senior leaders. The Head of Growth Marketing makes sure that trust turns into pipeline and revenue.

You'll own how marketing wins new clients: finding, engaging and converting the organisations most likely to buy from us. The right accounts, the right people within them, the right message, at the right time. That means building an account-based, data-led demand generation programme from the ground up, with a written playbook and clear measures. It covers our core business and the newer areas where we're growing: new markets, new propositions and new lines of business where pipeline has to be built from scratch.

Two partnerships sit at the heart of the role. With our Marketing Operations Lead, you'll build a best-in-class, technology-enabled and data-enabled demand engine, turning intent signals, scoring and account data into targeted action. With our highly skilled New Business sales team, you'll run joint plays on target accounts, agree what a qualified opportunity looks like, and build the feedback loop that tells us what actually converts.

This is a founding role. It suits someone who can set the strategy and run the programmes themselves, who is comfortable being measured on pipeline, and who wants to build something properly. As the programme proves its return, we expect to build a growth team around it.

Key Responsibilities

Growth strategy and targeting

• Own the growth marketing strategy and annual plan, tied to company revenue targets and our priority sectors
• Define, with New Business and Marketing Operations, our ideal customer profile, target account list, account tiering, and the personas and buying groups within those accounts
• Write it down: build and maintain a shared growth playbook that marketing and sales both work from
• Design account-based programmes across one-to-one, one-to-few and one-to-many tiers

New business and new markets

• Focus on new logos: winning the organisations that don't yet work with us
• Build pipeline for our newer propositions and markets as well as our core business, and help shape how each one goes to market
• Direct the wider marketing team's work towards one goal: qualified account opportunities for New Business to convert. That means events that move accounts forward, customer proof points that build confidence, PR and earned media that open doors, email nurture that keeps accounts warm, and answer-engine optimisation (AEO) so we show up when buyers ask AI tools

Building the demand engine with Marketing Operations

• Work hand in hand with the Marketing Operations Lead to build a best-in-class, tech-enabled, data-led demand generation capability across intent data, scoring, qualification, routing and attribution
• Turn the signals and data that system produces into action: which accounts to prioritise, who to reach, when and with what
• Partner with the Marketing Operations Lead on selecting and rolling out our account-based and intent platform. Marketing Operations owns the platform; you're its lead commercial user
• Use AI tools to work faster and smarter, and help set the standard for how the wider team uses them in demand generation

Partnering with New Business

• Run coordinated account plays with the New Business team, sequencing marketing and sales activity on priority accounts
• Agree qualification definitions and handover with sales leadership, and run a regular rhythm of pipeline review and feedback
• Equip sellers with timely account insight and relevant content for their conversations
• Build a relationship of trust with sales, grounded in shared targets and honest data

Campaigns and channels

• Plan and run demand campaigns across paid social, account-based advertising, search, email and nurture, events and partner channels
• Select and package our editorial, research, video and community content for in-market audiences
• Own the growth budget, run a disciplined test-and-learn approach, and move spend to what works

Measurement

• Own the number that matters most: qualified account opportunities delivered to New Business, along with the measures behind it (target account engagement, pipeline created and influenced, velocity, conversion and win rates)
• Set the benchmarks: in your first 90 days, establish baselines and agree realistic targets with the Marketing Director
• Report clearly to the Marketing Director and leadership team on what is working, what isn't and what we'll change

Candidate Specification

Essential

• Significant B2B marketing experience (typically 7+ years), including senior ownership of demand generation, account-based or growth marketing and a track record of building qualified pipeline

• Proven, close partnership with sales teams, and credibility with sales leaders
• Hands-on experience with marketing automation and CRM (HubSpot preferred) and with account-based or intent data platforms
• Commercially minded and numerate: confident with funnel metrics, attribution, budgets and forecasting
• Able to set strategy and execute it, and comfortable working in a growing team where you'll build as well as run
• A clear communicator and a strong writer
• Actively uses AI tools in their own work

Desirable

• Experience selling into large enterprises, regulated sectors (such as financial services, pharmaceuticals or health) or the public sector
