Pioneering Regenerative Materials
Seafoam Materials makes carbon-storing insulation from seaweed and upcycled waste
Designed for today’s construction methods
We believe meaningful change in construction happens when materials fit the industry as it is — while quietly helping it become something better.
Seafoam Materials replaces energy-intensive conventional insulation with carbon-storing alternatives, locking in carbon for the lifetime of the building.
Material properties
High thermal performance
Direct replacement for leading insulation types
Carbon-storing
Stores more carbon than is emitted during its manufacture
Circular inputs
One ton of waste is diverted from landfill for every home that uses
Non-toxic
Made without petrochemical or toxic additives
Compostable at
end of life
All-natural, fully compostable composition
Why insulation
The materials we build with can have a huge climate impact long before anyone moves in.
Construction materials account for 13% of global carbon emissions1. In Canadian residential construction, insulation is the second highest emitting material, after concrete2.Seafoam Materials replaces energy-intensive conventional options with carbon-storing alternatives, locking in carbon for the lifetime of the building.

Why seaweed
Seaweed captures carbon faster than any plant, and restores marine ecosystems as it grows.
It's a highly scalable regenerative solution that doesn’t require land or freshwater to grow1.Seaweed's unique binding properties make it an ideal option for construction materials - it’s naturally fire and rot resistant, and non toxic.

Biomaterials Innovation Associate
Vancouver, BC (Hybrid) • Full-time • September 2026 – March 2027 • $24–26.50/hour
Seafoam Materials is developing carbon-storing building insulation made from seaweed and upcycled fibres. We’re building healthier, lower-carbon alternatives to conventional insulation that can help reduce construction emissions, divert waste, and support regenerative supply chains.We're looking for a curious, hands-on Biomaterials Innovation Associate to join us as one of our first employees and help advance our seaweed-based materials from lab-scale development toward pilot-scale manufacturing.This role offers a unique opportunity to work directly with founders, scientific advisors, research partners, and industry collaborators at the intersection of biomaterials, climate technology, and startup innovation.As one of Seafoam's first employees, you'll have the opportunity to help shape not only our technology, but also how we work as a company. The work is collaborative, hands-on, and constantly evolving. We value curiosity, initiative, open communication, and a willingness to tackle challenges that don't come with a playbook.What You'll Do• Support biomaterials R&D and prototype development
• Assist with bench-scale iterative prototyping, materials processing & testing, sample preparation, and lab documentation
• Help coordinate activities with research and industry partners
• Contribute to product development, commercialization, marketing, and startup operations
• Help build the systems and processes that enable Seafoam to scaleWho You AreYou may be a senior student, recent graduate, or early-career professional with a background in materials science, chemical engineering, chemistry, biomaterials, environmental science, or a related field.We're looking for someone who is:• Curious and eager to learn
• Organized and detail-oriented
• Comfortable working in a hands-on prototyping, lab-scale and warehouse environment
• Proactive, collaborative, and self-motivated
• Resourceful and comfortable figuring things out when the path isn't obvious
• Passionate about nature-based climate solutions and sustainable materialsWhy Join Seafoam?• Work alongside founders, researchers, manufacturers, builders, and industry partners to help bring a new climate technology from lab-scale development toward real-world deployment.
• Gain experience in biomaterials innovation, product development, and commercialization
• Collaborate with researchers, manufacturers, builders, and industry partners
• Help develop a new generation of carbon-storing building materialsEligibilityCandidates must be between 15 and 30 years of age, legally entitled to work in Canada, and eligible under the requirements of the funding program supporting this position.ApplyApplications are reviewed on a rolling basis.
