About the role

We're looking for our first marketing hire, a motivated Marketing Specialist who's excited to support the growth of Sintali’s services and strengthen our presence across global markets.

This is a hands-on, execution-focused role working to established marketing priorities and campaigns and is perfect for someone who enjoys variety in the work they do. As we’re a small organisation, you’ll be reporting to the CEO, perfect for someone who wants to work directly with leadership and grow with a scaling company.

You’ll be responsible for producing high-quality marketing outputs across channels, regions and audiences, helping to translate plans into clear, consistent and effective materials.

This role is standalone and would suit a marketer who enjoys working in a fast-moving environment and who takes pride in producing strong work, managing multiple tasks, and contributing to commercial and growth objectives.

As Sintali continues to scale, this role will play a foundational part in reinforcing Sintali’s presence in key markets, supporting lead generation for certification services, and enabling commercial growth.

About Sintali

Sintali exists to accelerate the transition to a sustainable built environment.

The built environment is one of the largest drivers of global emissions, but it also offers one of the biggest opportunities for measurable, scalable impact. Sintali was founded to turn sustainability from aspiration into action by ensuring that environmental performance in buildings is independently verified, credible, and delivered at scale.

We are an environmental certification body and a global certification partner for IFC’s EDGE green building standard. We also own and operate the UK’s leading benchmark for green infrastructure, Building with Nature. Through certification, technical review, quality assurance, and training, we support projects around the world to design and deliver buildings that use fewer resources, reduce environmental impact, and align more closely with natural systems.

Our purpose is simple: to make green buildings the norm, not the exception. By combining technical rigour with practical delivery, we help the industry build better places for people and for the natural world.

Sintali operates a distributed sales model, working closely with a variety of partners from consultancy firms to associations and institutions to advance EDGE and Building with Nature. Today, Sintali has projects in over 100 countries, working across diverse markets and building types. As a purpose-driven, international organisation operating at scale, well-run commercial operations are essential to delivering impact and growth.
