About PetLabCo.

PetLabCo.® is the world leader in DTC pet supplements, with nine-figure revenue and ambitious plans for continued global expansion. We make science-backed supplements, health care and treats that millions of dog owners love, powered by a performance marketing engine spending at serious scale across paid social and beyond. Behind that engine we're building a brand that dog owners recognise and trust, which is what turns a strong first purchase into a long relationship. Our team is vibrant, fast moving and customer obsessed. High performers are valued here and they're rewarded, which makes this the ideal place for an ambitious, hardworking animal lover who wants to move their career forward quickly.

About the role…
Positioned within the Growth department, we move fast, test constantly and we're aggressively integrating AI across our entire growth stack. This is a senior role that asks for comfort with both strategic direction and hands-on execution. You'll own a complex, always-on trading and optimisation programme, balancing the immediate performance opportunities against the longer-term initiatives that compound value. Thriving here means knowing when to zoom out to shape direction and when to dive deep to drive the outcome.

Reporting to the founder, you'll lead the scope and delivery of our DTC growth roadmap across the US, Canada and UK. You'll be accountable for end-to-end performance, keeping strategy and optimisation tightly connected and commercially impactful.

What you'll own…
- Experimentation at scale - Experimentation is our decision engine here and not just a side project.
You'll use data, insight and structured testing to shape the roadmap, prioritise opportunities and
prove impact. Deep experience designing, running and scaling experiments in a live trading
environment is essential.
- Product and optimisation through a trading lens - You'll set the top standard for on-site customer
experience, with expert ownership of suggested change requests designed to improve the customer
experience and drive revenue. We treat the site as a trading floor, not a static asset.
- Optimising for LTV:CAC - As a subscription-led business we optimise for profitable long-term
lifetime value, not just short-term wins.

You'll treat LTV:CAC as the real measure of ROI, which asks
for a genuine understanding of the full customer journey and strong analytical capability.
- Growth marketing and landing page optimisation - You'll bring real fluency in growth marketing
mechanics and proven experience optimising landing pages in a paid social environment, with an eye for operational efficiency as well as top-line growth. That said, it won't just be that. As a hands- on role, you'll also own other areas of the experience that support acquisition and retention.
- Data and funnel fluency - You'll be highly data literate, with funnel dynamics and best practice
CRO as a second language.
- Leading the team - You'll inherit a high performing, driven and ambitious team, with each person
owning their own product area. Your job is to drive performance while keeping them engaged and
happy, leading through enablement and encouragement and leaving them empowered to succeed.

Your day to day will look a little like this
- Monitor growth metrics and business performance, turning what you see into clear recommendations and action
- Get into the pages themselves, assessing journeys and interrogating funnel behaviour to understand why the numbers move, not just that they did
- Handle the commercial side of ecommerce, from pricing assessments and promo opportunities to the risks that need spotting and acting on
- Lead multiple growth projects from first idea through to delivery, making sure they land what they set out to
- Move comfortably between short term tr
