Assistant Sustainability Adviser

Help small businesses cut carbon, cut costs, and build a more sustainable Northern Ireland.

Are you looking to launch your career in sustainability and make a genuine difference?

Sustainable NI is looking for an Assistant Sustainability Adviser to join our team and support small and medium-sized enterprises (SMEs) across Northern Ireland and the border region as they decarbonise, become more productive, and save money.

This is a fantastic opportunity for an early‑career professional to gain hands‑on experience across advisory work, project delivery, and stakeholder engagement, with structured mentoring and real scope for progression.

About the role

You'll provide direct support in the operational running of the E‑DATA project (Enterprise Digitalisation and Transformation Alliance) — a major cross‑border initiative funded by PEACEPLUS, helping SMEs modernise, innovate, and decarbonise.

In this role, you'll:

• Advise and support SMEs on their decarbonisation journey
• Contribute to sustainability reports and guidance documents
• Coordinate stakeholder engagement and support workshops, events, and training
• Provide administrative and project support
• Draft tender submissions and funding proposals
• Monitor policy developments and draft consultation responses on climate and sustainability issues

This is a hybrid role: two days per week in our Belfast office, combined with home working and regular travel across Northern Ireland and the border region.
