Senior Manager, Cloud Platform and Security

America is under sustained cyber attack. Our adversaries infiltrate our networks, steal our IP, and degrade the digital infrastructure that modern life runs on. They’ve learned—correctly—that those attacks rarely produce consequences.

Twenty was founded to change that, by making our adversaries think twice before they attack us. Our vision is American and allied primacy in cyberspace—a future where they cannot contest us, deterrence is assured, and the free world remains secure.

Founded in 2024, Twenty Technologies ((Use the "Apply for this Job" box below).) industrializes offensive cyber operations for the U.S. and its allies. Headquartered in Arlington, Virginia, Twenty has raised $168M from Khosla Ventures, Accel, Caffeinated Capital, Friends & Family Capital, Point
72 Ventures, General Catalyst, and In-Q-Tel.

You will build and lead the engineering organization that gets Twenty's software into the environments where our customers use it, keeps it secure and running there, and keeps it accredited. That covers infrastructure and the delivery path into customer environments, security engineering for our products, site reliability engineering at headquarters and at customer sites, and a new accreditation program for our products on government networks.

You will decide what gets built first, hire the people who build it, and lead them directly while the organization grows, often in disciplines where they know more than you do. You'll need enough technical depth to lead those specialists credibly, the judgment to make sound decisions in areas you haven't worked in yourself, and the organizational instincts to grow a new function.

Our product engineering teams are your peers and your main customers. You succeed by giving them tools, defaults, and a delivery path they want to use, not by doing their work for them. You'll partner closely with the VP of Engineering on org strategy and hiring, and with the product engineering leaders on what this organization provides them.

• Build the organization: decide what to stand up first, how the work is divided into teams, and when to add management capacity, in partnership with the VP of Engineering.
• Hire across infrastructure, security, reliability, and accreditation: set the bar for each discipline, run a structured process, and close strong candidates in a cleared hiring market.
• Lead and develop senior engineers directly, as well as the managers you add as the organization grows.
• Own the delivery path from a developer's laptop to a running instance, including instances we can't reach interactively: build, signing, packaging, install, upgrade, and rollback in customer environments.
• Take over infrastructure work that product teams are doing today, and build a team resilient enough to keep owning it.
• Own the operation of our products in our cloud and at customer sites, including incident response across the boundary between them.
• Lead security engineering for our products: design review, secure defaults, vulnerability management, and detection, working with our managed detection and response provider.
• Stand up and own an accreditation program for our products, through a dedicated lead who reports to you.
• Communicate clearly to senior leadership on progress, risks, and the tradeoffs you're making.

• You're equally comfortable in a data-model review, a customer conversation, and a 1:1—you bring the same rigor to each.
• You think in systems: data pipelines, marketplace incentives, interfaces, trust boundaries, team structure, and delivery dependencies—not just tickets.
• You can turn ambiguous operational needs into clear engineering problems, measurable…
