Engineering Director, Application Security

What You’ll Achieve
Lead technical delivery. Own the quality and profitability of every engagement your team ships. Review findings, guide technical direction on complex audits, and step in when projects need senior expertise. Maintain direct relationships with your most important clients.
Staff and grow the practice. Make project assignment decisions that balance engineer development, client needs, and profitability. Manage utilization, identify when to hire, and build the pipeline through the intern program and recruiting. Own the practice's P&L.
Develop your engineers. Create space for your team to present at conferences, publish research, contribute to open source tools, and advance their careers. Identify and remove obstacles. Your success is measured by their output, not yours.
Set technical direction. Decide where the practice invests in tooling, methodology, and capability development. Stay hands-on enough to know what's working and what isn't. Ensure the team's approach evolves with the threat landscape and client needs.
Integrate AI into the practice. Champion and model the use of AI tools across your team's workflows. Help engineers adopt AI-assisted auditing, reporting, and research practices that amplify their effectiveness.
