Sustainability Leader

Indianapolis, United States | Posted on 06/02/2026

CSO is seeking a full-time Sustainability Leader to serve as the firm’s primary expert and advocate for sustainable design, guiding the integration of environmental responsibility, energy efficiency, carbon reduction, and resilience into all projects. This role provides strategic direction on sustainability across the firm’s portfolio, advises project teams, leads project certification pursuits, and drives thought leadership to position the firm as a leader in sustainable architecture.

This position focuses on firm-wide sustainability strategy and expertise rather than day-to-day project management.
