Director of Cybersecurity

The Opportunity 

The Director of Cybersecurity is the senior-most internal security leader at Momentum. You own the security program end to end across the holding company and the portfolio: strategy, roadmap, budget, team, and the risk narrative that reaches the board.

You’ll build and lead a team of 4–6 — from operations and cloud security engineers through GRC and risk analysts — and you’ll set the standard for how that team works. This is a leadership role with technical teeth. You won’t live in the console, but you’ll be expected to hold your own in an architecture review, take incident command when severity demands it, and tell a portfolio CTO why their approach doesn’t clear the bar. Momentum is a multi-entity environment where each business runs its own dev and product teams. Influence matters as much as authority here.

Join us in this full-time role, based in our Dallas Office at the Link: 2601 Olive Street, Dallas, TX. Be part of a vibrant community where amazing people, data & insights, and perpetual innovation converge to shape the future of digital commerce!

About This Role at Momentum

As a Director of Cybersecurity on our IT team at Momentum, your days will be dynamic and filled with opportunities to contribute to our mission. Here’s a glimpse into what your overall responsibilities might look like:

• Start your day by reviewing the threat landscape, alerts, and the health of your security program across the portfolio.
• Collaborate with cross-functional teams to assess risk, review security architecture decisions, and identify opportunities to strengthen our posture.
• Join a team working session to align on priorities, pressure-test technical assessments, and set the strategy for the cybersecurity function.
• Engage with portfolio company leaders and engineering teams, leveraging influence and relationships to raise the security bar across the business.
• Implement security standards and controls across cloud, identity, and endpoint, making the build-versus-buy and platform-consolidation calls.
• Work closely with our partners at Momentum companies, empowering them to build and ship securely.
• Dedicate time to staying current on emerging threats — and to modeling AI-native, automation-first ways of working.
• Attend business reviews, incident tabletops, and vendor and vCISO check-ins to drive outcomes.
• Plan for upcoming initiatives — roadmap, budget, headcount, and M&A security due diligence — with your team.

Qualifications

We’re looking for someone who:

• Holds a Bachelor’s degree, ideally in computer science or information security (equivalent hands-on experience welcome).
• Proven track record owning a cybersecurity program — strategy, roadmap, and execution — not just one slice of it.
• History of solving security challenges through creativity, technical depth, and critical thinking.
• Demonstrates genuine hands-on technical ability — you can read the architecture diagram and find the problem, and take incident command when it’s needed.
• Ability to build relationships and lead through influence across multiple businesses, rather than authority.
• Displays empathy and flexibility — someone who partners with the business rather than policing it.
• Excels in communication, framing risk so leaders can make decisions — without fear or scare tactics.
• Strong understanding of security across cloud (AWS, GCP, Azure), identity, vulnerability management, and incident response.
• Proficiency with modern security tooling (MDR/EDR, SIEM, SASE, CASB/DLP) and AI tools used daily in the workflow.
• History of leadership and initiative, including building and developing a team.
• Passionate about building and sustaining a strong security program and making a positive impact.
• Demonstrates sound judgment and the ability to stay calm and accurate under pressure, including during live incidents.
• Can handle multiple priorities in a fast-paced environment, navigating ambiguity.

When considering experience for this role, we typically find a great fit with candidates who have a minimum of 8+ years of relevant cybersecurity experience, including time owning or running a security program and team. Additionally, experience in a holding company, private equity, multi-entity, and/or start-up environment is a definite plus.
