About GreyNoise 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 Benefits Equity in a high-growth, Series-A startup ️ 100% covered health, dental, vision, and life plans for all employees 6️⃣ Competitive 401k employer match of 6%, which is special for a startup.

To encourage time off from work and ensure overall employee health and wellness, GreyNoise strongly recommends each employee to take at least 120 hours of PTO (3 weeks) annually, including at least five consecutive business days Remote-first culture. While we are headquartered in the Washington DC area, we have a distributed workforce - with the majority of our team working remotely from across the country Equipment budget. Every new employee gets $3,000 to spend on equipment, so you can pick whatever works best for you Paid family leave for all employees. We offer 4 months of paid leave (birth or adoption), plus 2 months of optional unpaid leave, so new parents have time to adjust to the new life (and work) schedule Learning & development budget. All employees receive an annual $1,500 towards professional development related to their job function. The stipend can be applied to tuition, books, conferences, and more Company offsites and monthly local hangouts to encourage team bonding 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 Check out our (work-in-progress) longform culture document. 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.
