About the Role

This is a hands-on, execution-focused three-month fixed-term contract where you will design and activate end-to-end HubSpot lifecycle journeys, define segmentation and lead scoring logic, and build the reporting infrastructure to measure performance. You will own daily campaign operations, tracking, and optimisation, collaborating with a cross-functional team. The primary scope is lifecycle automation and CRM, with potential expansion to full paid media campaign management.

Responsibilities

Design end-to-end HubSpot lifecycle journeys to improve retention, reactivation, and cross-sell performance across enterprise accounts.
Build and launch HubSpot automation workflows, ensuring accurate integration with Salesforce.
Define segmentation, lead scoring, and audience logic to sharpen targeting precision and MQL quality.
Troubleshoot front-end marketing automation issues across landing pages, forms, and email journeys.
Manage lead routing processes and ensure accurate, timely handover to sales teams.
Set up lifecycle tracking, performance dashboards, and reporting frameworks to surface clear, actionable insight.
Own full-funnel reporting: pull and interpret data from GA4, HubSpot, and Salesforce to produce performance reports for internal teams and client stakeholders.
Translate complex engagement and campaign data into practical recommendations that inform strategy.
Validate tracking tags and pixels before new campaigns or platforms go live; coordinate fixes with analytics and development teams as required.
Maintain a structured testing and optimisation backlog; run experiments and apply learnings continuously.
Identify opportunities to improve lifecycle journey performance, MQL quality, and conversion rates.
Support paid media execution across LinkedIn, Google Ads, Meta, and programmatic platforms as required.
Assist with campaign pacing, spend reconciliation, and creative spec delivery alongside the Performance Marketing Manager.
Implement landing page updates and copy optimisations aligned with SEO best practice.
Schedule and build email campaigns; QA outbound comms including webinar sequences.
Act as the day-to-day owner for campaign operations and reporting, working closely with media, analytics, and the creative studio.
Communicate proactively and clearly with internal and client stakeholders across all active workstreams.

Requirements

Proven hands-on experience with HubSpot — building automation workflows, managing integrations, and troubleshooting front-end issues.
Strong GA4 proficiency: confident pulling, interpreting, and acting on analytics data to drive campaign and site improvements.
Experience with Salesforce alongside HubSpot, including workflow management and integration troubleshooting.
Solid Excel or Google Sheets skills, including building and maintaining reporting templates and pivot-based analysis.
Experience in a B2B digital marketing environment, agency-side or client-side.
Meticulous attention to detail — campaign setup, tracking, and lead routing require rigorous QA at every stage.
Clear, confident communication: able to translate data and insights into recommended actions for both technical and non-technical stakeholders.
Comfortable managing multiple priorities autonomously, with a pragmatic, outcomes-focused approach.
Hands-on paid media experience: Google Ads, LinkedIn, Meta, and/or programmatic platforms.
Familiarity with Google Tag Manager and copy-level SEO best practices.
Experience with data visualisation tools.
Proficiency with Gen AI tools relevant to digital marketing — using AI to support campaign analysis, content testing, or automation design.
Experience developing personal AI-assisted workflows to improve efficiency and output quality.
Agentic approach to problem-solving: able to break down complex, multi-step challenges systematically and identify clear paths forward.
Ability to critically evaluate AI-generated outputs and apply sound human judgement before acting on them.
