The posting, in Twenty's own words
archived Sep 29, 2026About 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 ) 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, Point72 Ventures, General Catalyst, and In-Q-Tel.

Role Summary
You'll be based in Twenty's New York City office, building and operating the data integrations that feed Twenty's mission-critical platform. Twenty builds software for cyber operations, and the applications this role feeds are used by operators and analysts working against hard national security problems. This is a hands-on engineering role with real production ownership: you'll build the pipelines that retrieve, process, and integrate new data sources into our applications, monitor the health of the data flowing through the systems you can reach, and debug production issues when they surface. Where your work runs in environments you can't access, you'll partner with Twenty's forward deployed engineers, who operate on-site at customer facilities, to get it deployed and keep it healthy. You'll join the data platform team, reporting to its engineering manager. The data integration tooling you'll build on is young and under active development. You'll be among its first production users, and what you learn in operation will directly shape how it evolves. If you're an experienced data engineer who wants your work in the hands of operators the same week you build it, and you'd rather own a production system end to end than ship features into a backlog, this role is for you.

Data Source Integration & Pipeline Development
Design and build data pipelines that retrieve, parse, transform, and load new data sources into Twenty's applications, primarily as AWS Glue jobs written in PySpark. Investigate unfamiliar source systems and data formats, working with Twenty's engineers to understand semantics, access patterns, and constraints before writing code. Design schemas and data models that fit the platform's performance characteristics and the shape of the data, including analytical models in ClickHouse. Write code that is testable, debuggable, and maintainable by engineers operating it in environments you can't access. Tests carry unusual weight here: they're how the field trusts a change you'll never see run. Write integration code that meets the security standards of classified environments: no hardcoded secrets, disciplined credential handling, and audit-ready practices throughout, so your work moves through customer approval processes without friction.
