We have a loyal community of loving pet parents and over 5 million happy dogs whose lives have been positively impacted by our innovative products. Our team is vibrant, fast-moving, and customer-driven where high-performers are valued and rewarded. And it is the ideal place for an ambitious, hardworking, animal lover who wants to progress their career rapidly.

Amazon is one of our most important growth engines. We’re looking for a senior, hands-on Amazon Ads specialist to own paid media across our marketplace channels, starting with Amazon and expanding across Walmart, Chewy and other marketplaces over time.

This is a senior role. You will own strategy and execution across Sponsored Products, Sponsored Brands, Sponsored Display and potentially DSP, working closely with Marketplace, Retail, Creative, Brand and Analytics teams.

The Role

As PPC Lead, Marketplaces, you will own all paid media activity across our marketplace channels, with Amazon Ads as your primary platform. You’ll be the strategic and hands-on driver of how we plan, execute, optimise, and scale paid investment on Amazon (Sponsored Products, Sponsored Brands, Sponsored Display), as well as on other marketplaces (Walmart/Chewy) as our footprint scales. This is an individual contributor role for a senior, hands-on operator. You’ll work cross-functionally with Brand, Creative, Retail, and Analytics teams, and be trusted to set the agenda for marketplace paid media at PetLab Co.

Key Responsibilities

Strategy & Planning

• Own the paid media strategy for Amazon and other marketplaces, aligned to category, brand, and revenue targets.
• Build and manage budgets, forecasts, and channel mix across Sponsored Products, Sponsored Brands, Sponsored Display, and potentially DSP.

• Define KPIs (ROAS, TACoS,, NTB%, share of voice, incrementality) and the operating cadence used to track them.

Campaign Management & Optimisation

• Plan, launch, and continuously optimise PPC campaigns across our full Amazon catalogue - keyword strategy, bid management, targeting, dayparting, placements.
• Run a structured experimentation roadmap (A/B tests on creative, bidding, targeting, landing pages) and convert learnings into scaled wins.
• Partner with the Retail team on listing quality, pricing, promotions, and inventory health to maximise paid efficiency.

Creative & Content

• Brief, review, and iterate on paid creative - Sponsored Brands video, Stores, A+ content, DSP display - in partnership with our in-house Creative team.
• Translate performance data into clear creative learnings and feed them back into the testing roadmap.

Reporting & Insight

• Build and maintain reporting that tells a clear story: where investment is working, where it isn’t, and what we should do about it.
• Surface insights to senior leadership weekly and connect marketplace performance back to the wider growth picture.

Cross-Channel Collaboration

• Work closely with DTC paid media, retention and brand to ensure marketplace investment is coordinated with full-funnel growth, not siloed.
• Be a credible internal voice on Amazon, including for new launches, regional expansion, and category growth.
