Our Growth team manages multi-channel demand generation across the US, UK and 20+ other markets—fueling pipeline for SMBs through to global enterprises. A surge in paid social scale tests and creative iterations has out-paced our in-house capacity. We need a senior hands-on specialist who can own paid social execution end-to-end (strategy - launch - optimisation - reporting) and drive a rigorous performance-creative testing programme that lowers CAC. You'll be responsible for Strategy & Planning

• Translate ICP/segment briefs into UK & US paid-social plans (LinkedIn, Meta, YouTube, TikTok, Reddit)
• Build media mix & budget pacing models for six-figure monthly spend

Campaign Execution

• Set up, QA and launch ads, audiences, pixel/conversion APIs
• Own naming taxonomies & UTM governance so data flows cleanly into GA4/HubSpot

Creative Testing

• Architect test matrices (hooks, formats, motion vs static, UGC vs brand) and rapidly brief designers / editors
• Analyse thumb-stop %, hold rate and post-click quality to decide winners

Optimisation & Scaling

• Run daily/weekly bid & budget adjustments, audience refreshes, creative rotations
• Proactively propose “scale tests” (new channels, retargeting logic, offer variants)

Measurement & Insight

• Build Looker Studio dashboards and concise exec read-outs (SQLs, pipeline $, CAC, payback)
• Present insights to VP Growth & Head of People Ops weekly

Knowledge Transfer

• Document playbooks, train junior PMMs/SDRs on ad feedback loops, and recommend tooling (e.g., Motion, Reprise, Black Crow)

Requirements

• 3–5+ years B2B paid-social ownership with demonstrable lead-gen revenue impact
• Proven command of £/$100k+ monthly budgets across LinkedIn + Meta (bonus: TikTok, X, Reddit, YouTube)
• Deep understanding of performance-creative science (content hierarchy, hook testing, feed-first design)
• Fluent in conversion tracking (offline events, CAPI, HubSpot/GA4, Salesforce or equivalent)
• Data-driven storyteller—comfortable turning pivot-table insights into clear exec actions
• Strait-edge project management: you hit launch dates, document changes, and escalate blockers fast
• Strong written & verbal comms; able to collaborate async with designers, copywriters, dev, and RevOp

Nice to have's

• Experience marketing AI / SaaS products to SMB buyers
• ABM or intent-signal retargeting (6sense, Demandbase, RollWorks)
• Experience with motion-graphics briefing or basic editing (Canva, CapCut, Adobe)
• Familiarity with creative-automation platforms (e.g., Pencil, Adcreative.ai)

Engagement details

• Hours: 15–25 per week to start. We’d love to evolve into a full-time role if there’s mutual fit, but part-time contracting is fine long-term.
• Comp: Hourly or monthly retainer—no %-of-spend model. Tell us your preferred structure and rate.
• Start date: ASAP (ideally onboard next week).
• Location: Remote, with at least 4 hours overlap with London or Eastern-US business hours.
