About PlantSea

PlantSea is an award-winning materials innovation company creating seaweed-based alternatives to plastics for use in everyday products. Our proprietary biopolymer technology provides biodegradable, water-soluble solutions for single-dosing applications such as laundry and dishwasher capsules, with future expansion planned into agriculture, cosmetics, and food packaging applications.

We are entering our commercialisation phase, with a strong customer pipeline, signed letters of intent, and the backing of a committed investor base. This is a pivotal moment, moving from first commercial stage to scale-up, and marketing has a central part to play in getting us there.

PlantSea's culture is open, fast-moving, inventive, and supportive. We value communication, shared accountability and creative problem-solving across all levels. We are driven by a shared passion for sustainability and tangible environmental impact.

Role Overview

PlantSea is looking for a creative Marketing Manager to develop, lead and own our marketing function as we move from first commercial stage to scale-up.

This is a leadership role with a hands-on creative streak. You will set direction and drive campaigns, but you will also roll your sleeves up: designing in Canva, shooting photography and video, and making things that look and feel on-brand and brilliant. You will coordinate freelancers for specialist work, so the right skills are on each job, while personally protecting brand standards. As the business grows, so will the marketing team.

You will work directly with the CEO and the commercial and technical teams, translating our marketing strategy into consistent, high-quality activity. We know exactly where we are going. We need someone to own how we get the message there, and to make it land.

What You Will Own

Creative and Campaigns

Drive marketing campaigns from idea to delivery, owning and effectively sharing the results
Design brand and marketing assets in Canva to a high standard
Capture photography and video that bring the product, the science and the team to life
Set and hold the creative bar across everything we put out
Carefully produce and present campaigns and content, ahead of time, on a monthly basis

Strategy and Leadership

Lead the marketing function and deliver against our 2026 marketing strategy
Coordinate the internal team across comms, events and PR
Build and manage a trusted freelance roster for specialist delivery
Set priorities, keep momentum, and report on what is working and what to stop

Story and Content

Run our two core narratives: a brand and consumer story that creates demand, and a manufacturer story that eases supply
Build the case-study engine, capturing every pilot and launch as a documented story
Lead authentically on real science, real founders and real seaweed, with no greenwashing
Position our yellow film as a strength for eco-brands
Channels and Demand
Own our PR programme, our biggest driver of enquiries, working with trade press and our PR support
Lead LinkedIn and wider social, building toward 50,000 impressions a month by end 2026
Oversee the new SEO-led website and our segmented monthly newsletter
Support events and conference presence, from ChemUK and SEPAWA to PLMA and European Bioplastics
Produce educational content on PVOH, regulation and why seaweed

Measurement

Track qualified inbound, share of voice and brand awareness in target segments
Use Pipedrive, Mailchimp and Microsoft Forms to manage activity and pull insight
Report quarterly on performance, ROI and priorities

Skills and Experience

Essential

An exceptional communicator, in writing and in person, able to make technical material clear and compelling
Genuinely creative, with a strong eye and a portfolio that proves it
Hands-on design skills in Canva
Photography and video skills, comfortable shooting and editing your own content
A track record of driving campaigns and owning results
Confident managing multiple channels and setting priorities across them
Experience briefing and managing freelancers or agencies
Self-starting, organised and able to lead with minimal supervision

Desirable

Experience in sustainability, which matters to us, especially for how we handle language and claims
Science or technical communication, translating complex material for non-expert audiences
B2B and FMCG marketing, the world our customers and pipeline live in
Investor and corporate comms, useful as we grow and gear up for our next stage

Why Join PlantSea

Lead marketing at a company creating a genuinely new category in the packaging space
Real ownership and a direct line to the founders
Purpose-led work with tangible environmental impact
The chance to shape how a science-led story reaches the world

Pay: £35,000.00-£45,000.00 per year

Benefits:

Casual dress
Company pension
Employee stock purchase plan
On-site gym
Sick pay

Experience:

Marketing: 5 years (preferred)
