Responsibilities
- Master our data and capabilities. We’ve built world-class data collection for some key national security data sets. Understand how we’ve built it, what our differentiators are, and how to take it to the next level
- Understand our users. You’ll need to understand their missions, challenges, and expectations to build systems that help them
- Shape our collection approach. You understand how our systems interact with defensive systems, and will develop and implement technical plans that keep high-value data flowing
- Build and maintain stable, scalable systems. Our customers operate 24x7 and need access to fresh, rich, operationally-relevant data. You will design collection systems that remain stable under sophisticated automated detection regimes
- Contribute to agentic capability. Ensure the tools you build and collected data is usable by agents (tool-call readiness, retrieval patterns, schemas/metadata, evaluation loops, etc.). Identify gaps where the right data isn’t getting into agent tool calls and coordinate fixes

- Technically diverse and can adapt your tool stack quickly
- Ability to communicate crisply and write a one-pager that aligns stakeholders, communicates risks, and drives action
- Preference for structural resilience over reactive tactics
- Comfort with making hard prioritization calls with incomplete information
- Deep understanding of how network-level and browser-level signatures combine to form a holistic risk profile in modern detection systems
- Experience with web scraping, browser automation, and similar
- Experience with national security problems and workflows, data platform/product work
- Familiarity with agentic systems and what makes data 'tool-call ready'
- Full stack capability
- Active TS / SCI Clearance is a plus but not needed
