Senior Performance Marketing Manager

About the Company

For almost two decades, this business has quietly underpinned the UK's connectivity networks, and today its infrastructure carries a significant share of the market. Backed by major private equity investment, the business is now repositioning from a traditional telecoms infrastructure provider into a broader digital infrastructure platform, moving into new markets including transport, utilities, defence and public sector connectivity. The marketing function itself is being built from the ground up. Reporting into the Head of Marketing, this is a flat, fast-moving team still finding its shape, closer in feel to a start-up than an established department. This role will be a founding hire in that structure, working alongside colleagues owning brand and content.

About the Opportunity

This role goes beyond lead generation. You'll own the full demand generation and performance campaign strategy, aligned to pipeline priorities across core propositions, new product launches and vertical growth programmes, translating commercial goals into integrated, insight-led campaigns. You'll take a campaign from concept through to delivery: defining audience segmentation, messaging hierarchy, channel mix and offer strategy, then briefing and directing creative development in partnership with brand and content colleagues, before running a disciplined test-and-learn engine to optimise performance week on week. This is a genuinely cross-functional role, working closely with colleagues owning content and social, brand and creative, digital and SEO, and marketing technology and CRM, as well as sales leadership directly. You'll also own performance reporting and insight, from weekly dashboards through to quarterly narratives on what drove impact and why, and will need to be equally comfortable with commercial storytelling and hands-on campaign delivery.

Key Responsibilities

• Own demand generation and performance campaign strategy aligned to pipeline priorities across core and new business growth areas
• Translate commercial priorities into integrated campaigns, covering audience segmentation, messaging, channel mix and conversion pathways
• Define creative requirements and testing hypotheses, briefing and directing creative development without diluting brand
• Partner with sales leadership on account and segment targeting, lead quality and follow-up standards
• Lead end-to-end campaign delivery, from launch readiness through to optimisation and performance trading decisions
• Run a structured test-and-learn programme across creative, messaging and audience variants
• Collaborate closely with colleagues across content, brand and creative, digital and SEO, and marketing technology to deliver integrated campaigns
• Produce regular performance reporting, campaign post-mortems and quarterly performance narratives

Key Requirements

• Proven end-to-end demand generation or performance marketing experience within a complex B2B environment
• Strong track record designing and delivering standout, integrated campaigns with measurable commercial outcomes
• Experience with CRM and marketing automation platforms, ideally HubSpot or a comparable system
• Confident briefing and directing creative development in partnership with brand and content teams
• Strong analytical mindset, comfortable with conversion measurement, lead quality metrics and pipeline reporting
• High energy, proactive and comfortable operating with autonomy in a build-from-scratch environment
• Background in technology, infrastructure or another complex B2B sector; open to sector, but candidates from FMCG or B2C-only backgrounds won't be the right fit
• Able to commit to 3 days per week in the office; this is non-negotiable given the collaborative, early-stage nature of the team

This is a rare opportunity to build a performance marketing function from the ground up inside a business moving from telecoms utility to genuine digital infrastructure platform, with direct commercial impact and real influence over how that growth engine takes shape.
