GreyNoise is a mission driven security startup focused on helping organizations understand and mitigate risks from Internet scanning and exploitation. GreyNoise provides real-time intelligence on all actors scanning the Internet and how some of them are attempting to exploit vulnerabilities on assets connected to corporate networks. The intelligence is highly trusted because it's generated from a global fleet of thousands of purpose built sensors observing the Internet. Advanced data science techniques and AI are used to process millions of observed events into real-time intelligence for customers.

Organizations use GreyNoise intelligence to understand the background scanning noise on the Internet and reduce up to 40% of alerts in a SOC. Threat hunting, vulnerability prioritization, incident investigation, and emerging threat response are other popular use cases for GreyNoise. The user base includes more than 10,000 community users and with 100 plus paid customers.

_All positions are fully remote within the US, with optional office attendance at our DC area headquarters, unless otherwise specified. Applicants must have US work authorization.

A Few of Our Engineering Principles

Readability of code is judged by the reviewer, not the author
Deliver fast, deliver often
Tech is cheap, don't be afraid to throw it away
Write tests to ensure stability and trust in the system
Don't be afraid to change anything that already exists
Slow is smooth and smooth is fast
Distinguish internal customers from external customers
Technical compromises are good
Utility and adoption are factored into the success criteria of all prototypes

GreyNoise Culture

The hallmark of any great company is a palpable and viscous culture. The most important pillars of our culture are:

Be transparent, honest, and objective. This is what it means to be "clinical"
Empathize with customers, partners, and each other
Learn from mistakes and share the knowledge
The way feedback is delivered to one another matters as much as the feedback itself
Good work-life balance is the key to sustained productivity
The measure of a team member's effectiveness is how well the rest of the team operates in their unexpected absence
No such thing as a million dollar idea, only million dollar execution
Out-innovate our previous selves

Explainability

Any security product that is a "black box" that asks you to blindly trust it should raise red flags - we believe the same is true of your place of work. We obviously think GreyNoise is doing something unique, but don't take our word for it - ask any of our 150+ enterprise customers, investors, thousands of happy users, or dozens of journalists who have cited GreyNoise over the past few years.
