Senior Growth Marketing Manager - Business Banking (Contractor) LondonOakNorth Bank – Marketing /Contractor - Inside IR35 /On-Site APPLY FOR THIS JOB The role We’re hiring a Senior Growth Marketing Manager to own customer acquisition and growth for OakNorth Business Banking – driving deposit volumes, account opening, and activation. The role sits at the intersection of marketing, commercial and product. You will work closely with multiple teams and lead go-to-market execution for an actively expanding product suite – from savings accounts and Fixed Term Deposits to Finance Automation and escrow. This is a high-ownership role for someone who is as comfortable in a campaign dashboard as they are in a product launch war room, and who has operated in a regulated environment where every customer-facing message needs to hold up under scrutiny. What you'll be doing Growth and acquisition Own Business Banking acquisition across all marketing-attributed channels – paid search, paid social, affiliates, outbound, referral, events, and partnerships. Define and own the channel mix strategy: which channels to invest in, which to test, and which to cut – tied explicitly to CAC, deposit targets, and activation rates, not just traffic or leads. Work with each channel owner across the marketing team – digital, content, and outbound, to align strategies, share audience and performance insight, tailor messaging and ensure every channel is pulling in the same direction. Own the outbound targeting strategy for commercial: sector selection, data strategy, and sequence design in partnership with the BD team. Own landing page strategy and conversion rate optimisation – sector-specific pages, form design, and qualification logic. Monitor funnel drop-off across the acquisition journey — identify where the biggest leaks are, own re-engagement strategies for prospects who didn't convert, and feed learnings back into funnel and campaign design. Develop and iterate sector-specific messaging, tailoring copy and proof points for each target segment rather than relying on a single generic proposition. Constantly experiment with new channels: affiliate partnerships, introducer programmes, intermediary channels, with a clear hypothesis and measurement framework for each. Track, report, and improve acquisition performance: CAC, conversion rate by channel, application-to-activation rate, and deposit volume per acquired customer. Drive cross-sell and cross-product growth — identifying opportunities within the existing OakNorth customer base across Business Banking, Lending, and Personal Savings to deepen relationships, increase product adoption, and grow wallet share. Product and feature GTM Own go-to-market execution for BB product and feature launches — release planning, positioning, channel strategy, asset production, and compliance coordination. Lead acquisition campaigns for new releases in the product suite: including release plan, positioning, landing pages, email campaigns, aggregator outreach and activation sequences. Own product talk tracks for the product suite, keeping commercial team materials current as products and rates evolve. Coordinate cross-functionally across Product, Compliance, Legal, Engineering, and Operations for each release – developing and/or updating copy across the website and marketing materials. Brief and direct the Content Marketer, design team, and web team on launch assets Commercial enablement and BD alignment Act as the dedicated marketing resource for the Commercial team – not a separate function. Attend daily and weekly commercial reviews and bring marketing performance data, new campaign ideas, and channel intel. Produce the materials the BD team needs to convert: email copy, call scripts, talk tracks, objection-handling guides, and sector-specific one-pagers. Ensure inbound marketing messaging and outbound BD sequences are consistent, a prospect who's seen a LinkedIn ad and then received an outbound email must ex ...
