You will serve as the firm’s primary internal legal resource, partnering directly with the COO and executive leadership. This role is expected to participate as a member of the firm’s Operating Committee, contributing to enterprise-level decision making on risk, governance, and growth. This is not a traditional in-house support role.

Qualifications - J.D. and active bar membership. - 9–15+ years of legal experience, with a mix of law firm and in-house exposure. - Direct experience in or supporting consulting / professional services firms. - Deep experience structuring and negotiating complex commercial agreements. - Proven ability to design and stand-up legal frameworks, not just operate within them. - Demonstrated credibility partnering with executives and contributing at the operating committee level. Requirements - Experience standing up or significantly evolving a legal function from scratch or near-scratch. - Strong familiarity with data usage, privacy, and AI-related contractual considerations. - Experience leading diligence processes and supporting transactions. - Comfort operating as a “player-coach” in a fast-moving, non-bureaucratic environment. - Modernizing legacy contract frameworks. - Exposure to M&A coordination or acquisition support. - Building legal systems from the ground up. What Success Looks Like (first 6-12 months) - Rebuilt and standardized core client agreements (MSA, NDA frameworks). - Clear, adopted firm-wide negotiation positions and playbooks. - Established risk assessment and data governance baselines. - Improved speed, consistency, and confidence in contracting. - Trusted advisor status with executive leadership.
