Ann Arbor, United States Censys Full time

At Censys, our mission is to bring internet visibility and intelligence to the world's security teams. Our platform not only identifies potential threats, but provides actionable insights and enables proactive defense strategies. Founded by researchers and practitioners, we are deeply committed to the quality, trustworthiness, and transparency of our data and results. As our own strongest critics, we continuously innovate to better understand the Internet and empower our customers with the visibility they need to succeed.

As the Internet changes, so do our methods, and this is where the research team comes in. From deploying monitoring solutions, to investigating new areas of interest, to executing measurement experiments, we are constantly stiving to answer the question: what else can we find with Censys?
Role Summary

As a Security Analyst detailed to our Rapid Response function, you'll play a pivotal role in protecting our customers by tracking the impact of vulnerabilities on the internet. Working hybrid on-site, in one of our four locations, you'll dive deep into our dataset to extract detailed information about host configurations and their associated vulnerabilities.

You'll leverage your technical skills to write custom fingerprints that identify software families and their corresponding vulnerabilities. Subsequent blog posts on topical events will demonstrate your ability to translate a complex security event into something that is easy to understand and consumable by a non-technical audience. Additionally, you'll be working alongside a cutting-edge Research team whose main goal is to ensure that Censys maintains its position as the one place to understand everything on the Internet.
