About the role

What you’ll do

  • Master our data and capabilities. Understand how we’ve built world-class data collection for key national security data sets, our differentiators, and how to take it to the next level.
  • Understand our users and their missions, challenges, and expectations to build systems that help them.
  • Shape our collection approach by developing and implementing technical plans that keep high-value data flowing under defensive systems.
  • Build and maintain stable, scalable systems that remain reliable under sophisticated automated detection regimes.
  • Contribute to agentic capability by ensuring tools and data are usable by agents (tool-call readiness, retrieval patterns, schemas/metadata, evaluation loops, etc.) and coordinate fixes for gaps.

You might be a fit if you

  • Have strong back-end experience and understanding of distributed systems. Prefer TypeScript/Python expertise.
  • Understand how anti-abuse, bot detection, fraud, or traffic integrity systems analyze traffic at scale.
  • Are data driven with an eye for instrumentation and monitoring.
  • Can reason about how small deviations in protocol behavior, timing, or runtime characteristics propagate into anomaly scores.
  • Are technically diverse and can adapt your tool stack quickly.

What we value

  • Deeply understand how network-level and browser-level signatures combine to form holistic risk profiles 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 (leans backend, touches frontend with React).
