About KURK
KURK is a mission-driven health brand tackling one of the world’s biggest health challenges: inflammation, chronic pain, and longevity.
Founded by two best friends after their own battles with cancer, we are developing the world’s best natural solutions for common health challenges in our own lab. We’re bootstrapped, profitable, and obsessed with doing things properly: real science, real results, real customers.
Today we have:
• Vertically integrated product pipeline with industry-leading repeat purchase rates and a Science Advisory Board with 2 medical doctors and 3 health Ph.D.’s
• Fast DTC growth across the UK, US, and Australia — with the US as our primary expansion market
• Research partnerships with Medical Schools and universities - we deeply understand the health problems we are solving.
We’re building the defining natural health brand of the next decade — and now we need a Head of Marketing to own and scale our growth engine.
The Opportunity
This role sits at the intersection of performance marketing, brand building, and e-commerce. You’ll be responsible for driving profitable acquisition and retention across all digital channels — with a particular focus on scaling our US market presence — while ensuring our Shopify storefront delivers a world-class experience.
Reporting directly to the CEO and joining our leadership team, you’ll be both strategic and hands-on. You’ll have the mandate to build the team, systems, and campaigns that fuel KURK’s next stage of growth.
We’re looking for a senior performance marketer who has grown into full-funnel leadership. Someone who can scale acquisition without losing discipline, build brand trust, and turn a working system into a repeatable growth machine.
Key Responsibilities1. Acquisition (Performance Marketing)
• Own strategy and execution through our agency across Meta, Google, YouTube, Influencer, and PR amplification
• Manage and optimise paid spend with a sharp eye on CAC, LTV, and payback periods
• Build and execute the US growth playbook — this is the mission, not a side project
• Test and scale new channels (affiliate, healthcare practitioner referrals, partnerships)
2. Retention & Lifecycle Marketing
• Drive our agency performance for Klaviyo CRM: flows, campaigns, segmentation, churn reduction
• Improve our subscription and loyalty programs to increase retention and LTV
• Run personalised campaigns targeting 40+ wellness customers and new recovery/longevity segments
3. Conversion Rate Optimisation (CRO)
• Lead A/B testing with our e-commerce team across landing pages, upsells, checkout flows, and subscription funnels
• Ensure tracking and attribution are clean across Shopify, GA4, and paid platforms
• Drive continuous improvements to conversion rate, AOV, and repeat purchase rate
4. E-Commerce & Tech Stack
• Oversee management of our e-commerce for the Shopify Plus storefront
• Integrate and optimise tools (subscriptions, attribution, review platforms, CRO tools)
• Own reporting dashboards to provide real-time growth and performance insights
5. Brand, Narrative & Trust
• Turn science, clinical trials, and founder story into clear, compelling messaging
• Balance performance with brand — you understand both matter
• Build authority in pain, inflammation, and longevity through PR and credibility-led acquisition
6. Leadership & Team Building
• Build and manage a lean team (growth marketer, CRM exec, paid media buyers)
• Collaborate with our science, creative, and operations teams to launch products and campaigns
• Work directly with CEO to align marketing strategy with overall company growth
What Success Looks Like
• Predictable, scalable growth engine across three markets
• Proven US acquisition model working at scale
• Strong CAC:LTV performance and improving marketing efficiency
• Clear brand positioning that builds trust and reduces ad dependency
• A marketing function that runs without founder bottlenecks
About YouYou Must Have
• 5–10 years in DTC / e-commerce marketing, ideally in wellness, supplements, or CPG
• US market experience — you’ve managed US paid spend or led US expansion. Non-negotiable.
• Deep, hands-on expertise in Shopify, paid media (Meta, Google), CRM (Klaviyo), CRO, and analytics
• Proven record of scaling acquisition profitably with disciplined CAC:LTV
• Strong analytical skills — fluent in attribution models, cohort analysis, and dashboards
• Scale-up experience — you were at a company that grew 3x–20x. You were in the room.
You’ll Thrive If
• You’re ready to step up to the next level — this is your moment
• You want to build a function, not just optimise someone else’s
• You think like an owner — because you want to be one
• You’re hungry, resilient, and excited to help millions live healthier, longer lives
• You understand that brand is performance with a longer attribution window
