Senior Director of Investments

The Senior Director of Investments leads research, sourcing, and due diligence across the firm’s family office and nuclear decommissioning trust investment platforms. This is a hands-on, analytically rigorous role requiring deep investment expertise and a bottom-up approach to professional manager evaluation and selection. The position reports directly to the Chief Investment Officer and operates across Mariner Strategic Investments (family office) and the nuclear decommissioning trust portfolios. The Senior Director of Investments will partner closely with the CIO, with meaningful responsibility, visibility, and impact from day one. This role offers a unique opportunity to build and shape an institutional-quality manager research function within a dynamic and growing investment platform.
