Interim Senior Communications Consultant in Corporate Sustainability & Finance; ingevuld

Interim Senior Communications Consultant in Corporate Sustainability & Finance (ingevuld) Do you want to apply your communications expertise at the intersection of sustainability and corporate finance, working with senior decision makers from leading multinational companies?

Our client is a global, non-profit business network supporting 200+ large corporates on their sustainability transformation. The company is looking for a senior freelance communications consultant to strengthen the communications and branding of its Corporate Performance & Accountability (CP&A) program.

The organisation operates internationally, with hubs in Geneva, Amsterdam, London, Chicago, China and Singapore. The CP&A program focuses on integrating sustainability into financial decision-making, corporate reporting, investor engagement and executive-level governance.

You will support both the central communications team and the CP&A leadership in sharpening the program's story, increasing visibility, and ensuring consistent, high-quality communication towards financially oriented audiences.

Your role is a blend of strategic positioning, content development, and day-to-day communications coordination.

You will:

• Develop a clear and compelling positioning of the CP&A program, internally and externally.
• Translate complex, abstract sustainability-finance topics into clear, relevant messaging.
• Shape and deliver ongoing "drumbeat communication" around key events, milestones, publications and initiatives across the year.
• Identify the right audiences, channels and narratives for C-suite and senior corporate stakeholders.
• Work closely with subject-matter experts to co-create storylines and ensure clarity.
• Contribute to thought leadership moments, event planning and strategic communication opportunities.
• Write and edit a variety of content in excellent English (web copy, news updates, briefings, talking points).
• Manage stakeholders in a fast-moving, international context with many time zones and professional backgrounds.
• Push back constructively where needed: challenge vagueness, ask the right questions, and support the team in getting to a crisp narrative.

You will be part of a compact CP&A team and collaborate regularly with the organisation's central communications unit.

We are looking for someone who:

• Has strong experience in financial communication, corporate reporting, investor-facing communication or similar domains.
• Combines strategic capability with hands-on execution.
• Can quickly understand complex sustainability-finance topics and translate them into sharp, accessible messaging.
• Has experience in international (non-profit or corporate) environments with diverse stakeholders.
• Writes and communicates exceptionally well in English.
• Understands what resonates with senior corporate and C-suite audiences and can communicate in that tone.
• Is confident, resilient and unfazed by high-pressure or demanding personalities.
• Is senior enough to oversee the bigger picture, but not so senior that operational work becomes uninteresting.

• Knowledge of ESG, sustainability reporting, risk frameworks or corporate governance
• Experience working for membership-based international organisations

• Start: Immediate
• Duration: 6 months, with option for extension
• Location: Hybrid; fully international team; 1 day per week onsite in Amsterdam
