Senior Performance Marketing Manager

Are you a proactive B2B marketer who enjoys turning ideas into campaigns and using data to make them better? We’re looking for someone who can connect the right audiences with relevant content, build effective outreach and nurture programmes, and show how marketing contributes to growth.

You will build and run ICP’s demand generation activity, bringing together HubSpot, personalised sequences, paid media and reporting. This is a hands-on senior role: you will identify opportunities, recommend practical improvements and take campaigns from planning through to delivery and optimisation.

Working closely with Growth Directors and New Business, you will understand their target markets and priority accounts, then partner with the Content team to develop the marketing materials and campaigns that support meaningful client conversations. You will be a key stakeholder in how ICP uses HubSpot, owning day-to-day marketing processes and helping shape improvements with the teams who use it.

Key responsibilities

Build targeted demand programmes

• Plan and deliver demand generation campaigns for new business and existing accounts, with agreed audiences, objectives, budgets and measures of success.

• Work with Growth Directors and New Business to identify priority sectors, accounts, buyer roles and opportunities, including whitespace opportunities for additional services within existing clients.

• Research and enrich relevant contacts using HubSpot, ZoomInfo or similar tools, working with Growth colleagues to validate contacts and prioritise coverage gaps.

• Translate target-market needs into clear briefs for the Content team, coordinating tailored materials, messaging and assets for campaigns and Growth outreach.

Create and manage sequences and nurture

• Build, test, launch and optimise HubSpot sequences, email templates and supporting outreach materials for Growth Directors and New Business.

• Personalise sequences by industry, role, seniority and account needs; agree the audience, timing, sender and follow-up responsibilities with Growth colleagues.

• Develop marketing nurture workflows that keep relevant audiences engaged throughout longer buying cycles, using content aligned to ICP’s solutions and services.

• Coordinate pre-event engagement and post-event follow-up with the Marketing Coordinator, ensuring responses and engagement are captured and passed to the appropriate Growth colleague.

Key responsibilities continued

Manage paid media and campaign performance

• Plan, set up, manage and optimise paid campaigns across relevant platforms, including LinkedIn Campaign Manager and Google Ads, to promote ICP content, events and services.

• Manage audience targeting, approved budgets, campaign schedules and testing; use performance insights to refine messaging, creative and spend allocation.

• Work with Content to develop advertising assets and clear calls to action, coordinating landing pages and conversion journeys with relevant colleagues or partners.

• Maintain campaign naming, tracking links and conversion measurement so activity can be connected to HubSpot records and reported consistently.

• Coordinate any appointed paid media agency or specialist partners, agreeing delivery responsibilities and reviewing results against campaign and pipeline objectives.

Own day to day marketing operations in HubSpot

• Act as the key marketing stakeholder for HubSpot, maintaining effective campaign processes, contact segmentation, lists, workflows, sequences and reporting.

• Agree lead lifecycle definitions, scoring criteria, routing and handover processes with Marketing and Growth, then implement and maintain the agreed marketing configuration.

• Maintain the quality of marketing contact and campaign data through enrichment, deduplication, consistent properties and appropriate suppression, following ICP’s agreed data protection standards.

• Document workflows and campaign processes, and support colleagues to use sequences, templates and dashboards effectively.

• Identify system improvements and coordinate more complex configuration, integrations or technical issues with the Marketing Director and relevant internal stakeholders or external partners.

Track results and improve delivery

• Build and maintain dashboards covering campaign engagement, paid performance, sequence responses, lead conversion and marketing-sourced and influenced pipeline.

• Agree reporting definitions and baselines with Marketing and Growth, explaining what the data shows and where tracking or attribution has limitations.

• Share practical recommendations with Growth and Content on the audiences, themes and channels generating meaningful engagement and qualified conversations.

• Proactively test new approaches and use agreed automation and AI tools to improve research, personalisation and reporting, with appropriate review of accuracy and data handling.

How the role works with others

The Marketing Director agrees priorities, budgets and the balance between system improvement and campaign delivery. Growth Directors and New Business agree account priorities and own client relationships, sales follow-up and opportunity progression. This role provides targeted programmes, contact research, sequences and insight to support them. Content leads asset creation against agreed briefs, while the Marketing Coordinator supports campaign and event delivery. Wider HubSpot changes are agreed with the relevant business stakeholders.
