Job description

FleishmanHillard London is a globally connected, creatively driven communications agency. We help brands grow, protect and evolve through bold storytelling and insight-led strategy. As we continue to scale, we’re looking for a strategic and results-focused Growth & Marketing Manager (Senior Account Manager level) to support how we show up in the market and drive future opportunities.

This is a high-impact role that blends integrated marketing, lead generation, and agency brand building. You’ll sit at the heart of the agency, work across teams and specialisms with high visibility and support the engine that drives our UK growth efforts.

We’re after someone who’s commercially sharp, insight-led, and ready to take full ownership of growth marketing and new business. You’ll bring together performance thinking, content strategy, digital tools to help us reach the right prospects with the right message and convert interest into pitch wins.

We are committed to creating an inclusive and equitable working environment for everyone. As the only PR agency awarded EY’s National Equality Standard (twice!), all applicants will receive consideration for employment without regard to race, religion, ethnicity, gender identity, sexual orientation, national origin, disability or age.

NB: Offered initially as a 3 month freelance contract, there is the potential for the role to convert to permanent in the future.

The Team

You’ll be part of our UK leadership operations team but embedded across all practices and sectors, working closely with senior leads, creative, digital and client-facing teams to shape how FH shows up. You’ll have access to brilliant minds across creative, content, digital, and paid media to bring ideas to life. This is a hands-on role and it’s yours to own.

The Work

You’ll support our prospecting, marketing and business development programme. You’ll coordinate tailored pitch responses and high-impact thought leadership, to SEO-aware content and performance campaigns.

We’re looking for someone who understands the full acquisition funnel—from brand visibility and web engagement to creds meetings and conversion. You’ll test, iterate and optimise across platforms and channels, finding smarter ways to attract and convert leads, and embedding digital and AI tools along the way.

Key Responsibilities Include:

Prospecting & Growth Development

• Execute a UK-wide prospecting strategy aligned to priority sectors and agency growth plans
• Support tailored creds, chemistry meetings and initial POVs for high-value briefs (£200K+), working across integrated teams
• Manage inbound leads, qualification, and the new business inbox – ensuring timely responses and clear ownership
• Lead and document go/no-go decision-making with input from practice and sector leads
• Identify and activate new prospecting routes, including performance-led media, events, procurement leads and thought leadership

Marketing & Brand Strategy

• Own the marketing and visibility of FH London – including campaigns, content strategy and reputation-building initiatives
• Work across digital, paid, organic and owned channels to drive awareness and engagement with new audiences
• Optimise how our agency presents itself – from SEO-informed website content and social presence, to marketing collateral and pitch decks
• Integrate AI tools, CRM, and digital workflows into marketing and pitch processes to increase efficiency and targeting precision

Performance & Analytics

• Use marketing and pipeline data to inform decisions and refine strategy – including web analytics, social performance, CRM data, and campaign reporting
• Report on pipeline health, lead conversion, win rate and engagement – highlighting performance and missed opportunities
• Test and refine what works across the funnel – messaging, formats, channels – to drive stronger inbound and conversion rates

Cross-Team Integration

• Map talent across the agency and help assemble the right mix of capabilities to respond to opportunities
• Foster strong collaboration between practices and leadership – aligning on priorities, streamlining decision-making, and removing blockers
• Share UK insights into global and EMEA growth reporting and marketing initiatives
• Balance internal politics and dynamics with empathy, speed and clarity

What We’re Looking For

• Experience in growth, marketing, new business or performance comms, ideally in an agency or integrated environment
• Proven ability to support lead generation and marketing performance across multiple channels
• Excellent storytelling and content development skills – from creds to campaigns
• Commercially minded and data-literate – able to turn insight into action
• Highly organised and calm under pressure – able to juggle multiple workstreams
• Comfortable using or managing tools like GA4, HubSpot, Looker Studio, paid media dashboards, social analytics and AI writing/targeting tools
• EQ and political awareness – able to influence without authority, and lead with empathy

Bonus Points If You…

• Have experience running or managing paid media and SEO strategies
• Have supported or led a website optimisation or marketing automation initiative
• Have introduced AI or automation tools into marketing, CRM or new business processes
• Have led the creation of campaigns, events or content platforms to drive inbound opportunities

If you have experience in the above, we’d love to hear from you.

A Few Things We Think You’ll Love:

• A friendly and inclusive team with a global reach
• High visibility and influence across the UK business
• The freedom to shape how we market ourselves and who we target
• Opportunities to collaborate across the global Omnicom network
• Global mobility and secondment opportunities
• Flexible hybrid working with a culture that values work-life balance
• Amazing Culture Club perks – from rooftop yoga to in-house massages
• Comprehensive wellbeing and benefits package (BUPA, generous parental leave, gym membership, fertility & menopause support)
• Generous holidays, including birthday leave, Christmas closure and sabbaticals
