B2B Marketing Manager

About Ocean Bottle:

At Ocean Bottle, our vision is to restore the health of the ocean to a better state than we inherited it. We do this by bringing people together to fund plastic collection. We create award-winning reusable bottles and cups, with every product sold funding the collection of 1000 plastic bottles in weight - before they reach the ocean. To date, we’ve collected the equivalent of 1.8 billion plastic bottles from ocean-bound regions.

We believe that we don’t need a handful of people doing sustainability perfectly, we need millions doing it imperfectly. Our products and solutions enable consumers and businesses to drive this change and support refill behaviour whilst funding plastic collection. 

As a brand, we are change makers - we bring people together, we pioneer solutions and we connect others to the power of the ocean. If you're passionate about reducing the impact of plastic on our planet and the overall health of our ocean - we want to hear from you. We’re keen for people who share a connection to the ocean and with a drive to make a difference to join our mission.

As we scale, we need smart, strategic marketers who can connect impact with performance. That’s where you come in. We’re looking for a commercially minded B2B Marketing Manager to help us build a scalable pipeline of high-quality leads and maximise the performance of our B2B channels - from corporate partnerships to wholesale.

You’ll be responsible for driving our lead generation strategy and campaign execution, focusing on smart, measurable marketing activity that builds awareness, captures demand, and converts decision-makers. You'll use tools like HubSpot to create seamless journeys and track performance across the funnel, helping us drive meaningful partnerships and fund more plastic collection.

This is a pivotal role with both strategic oversight and hands-on delivery. You’ll sit at the intersection of Sales, Marketing, and Growth, taking the charge on demand generation while supporting our broader trade marketing needs.

• Monitor and report on marketing performance across channels, sharing learnings and optimising activity
• Manage and track the B2B marketing budget, ensuring spend is aligned with impact and growth objectives
