Staff Data Engineer - TS/SCI Cleared

ABOUT THE COMPANY

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 (www.twenty.io http://www.twenty.io) industrializes offensive cyber operations for the U.S. and its allies. Headquartered in Arlington, Virginia, Twenty has raised $138M from Accel, Caffeinated Capital, Friends & Family Capital, Point72 Ventures, General Catalyst, and In-Q-Tel.

You’ll partner closely with engineers and intelligence analysts to turn messy, high-volume operational data into reliable, well-modeled systems that drive real missions. You’ll also lead technical initiatives and mentor other engineers as we scale what we can support and ship.

- You’re opinionated about schema and index design, and you can explain tradeoffs clearly.

- You default to measurable reliability: data quality, lineage, repeatability, and operational excellence.

- You’re comfortable working with ambiguous datasets and evolving requirements without lowering standards.

- You collaborate tightly across roles, especially with engineers and analysts who need fast, correct answers.

- You take leadership seriously—mentoring ...
