About The Position

The Director of Cybersecurity is Momentum’s senior-most internal security leader, accountable for the end-to-end security program across the holding company and its portfolio. The role owns security strategy, roadmap, budget, team, and the risk narrative presented to the board. The director will build and lead a team of 4–6 across security operations, cloud security, governance, risk, and compliance, setting standards for how the team operates. This is a leadership role requiring technical depth. The director is expected to contribute to architecture reviews, lead incident response when needed, and influence portfolio technology leaders and engineering teams in a multi-entity environment. The position is full-time and based at Momentum’s Dallas office at The Link, 2601 Olive Street. The director will assess threats and program health, review security architecture and risk, establish security standards and controls across cloud, identity, and endpoints, and make build-versus-buy and platform-consolidation decisions. The role partners with portfolio companies to help them build and ship securely, models AI-native and automation-first working practices, and plans security initiatives, budgets, staffing, and M&A due diligence. The position also involves business reviews, incident tabletops, and vendor and vCISO check-ins.
