About GreyNoise

There are hundreds of cybersecurity companies telling their users what to worry about. GreyNoise is the only cybersecurity company telling users what not to worry about.

GreyNoise is an early-stage cybersecurity product company trusted by security teams all over the world. Our thousands of free users and dozens of enterprise customers use our products to:

• Understand the Internet
• Reduce drag in the Security Operations Center (SOC)
• Provide insights on opportunistic threats

Every day any given SOC has hundreds or thousands of alerts to investigate. GreyNoise takes a data-driven approach to making the SOC team more efficient from within the products they are already using.

We operate a large network of passive collector sensors in hundreds of data centers geographically distributed all around the world. These sensors collect and analyze “Internet Background Noise” which is converted into useful insights and made accessible to our web interface and integrations.

In other words, GreyNoise is like noise canceling headphones for security teams; we tell our customers what not to worry about by eliminating pointless alerts generated by devices all around the Internet.

We won’t stop until GreyNoise is a ubiquitous name in the security community.

• Maintain an ephemeral fleet of hundreds of Internet-facing servers
• Join the on-call rotation and help us improve our monitoring and alerting system

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 over 50 enterprise customers, investors, thousands of happy users, or dozens of journalists who have cited GreyNoise over the past few years.

• You are comfortable taking an idea from concept to customer
• You are open to both explaining your stance and questioning others in a clinical, open-minded, and respectful manner

Job Description

Luxor specializes in the physical delivery of hashrate (compute power). Over the past two and a half years we have been acting as a buyer of hashrate, purchasing, and mining over $40mm worth. We currently have 15,000 machines that sell us their hashrate daily.

Company Background

We fundamentally believe that compute power itself is a commodity and we want to build out traditional marketplaces and derivates for it.

We are building a spot-market for hashrate, not dissimilar to a compute-power version of Henry Hub. After this is completed we will begin building incredibly powerful and interesting derivative products on the value of hashrate.

You will develop the technical design for either cloud or on-premises solutions. Also, influence designs across R&D using original research and advanced analysis. You’ll design solutions for business critical and highly complex engineering projects by applying extensive domain expertise in performance testing. You’ll provide oversight of code and design reviews, and ensure features are delivered to meet business and quality requirements.

Our teams own mission-critical aspects of a rapidly growing, globally distributed platform (eg: Hashrate Marketplace and 15 unique mining pools), in the cloud, and, as such, you will have an incredible amount of impact on the current state and future direction of our product, with visibility throughout the organization and a significant opportunity to take ownership.

This role will report directly to the CTO.

This is a remote role (we are not sponsoring visas at this point). The ideal candidate is based between UTC-8 and UTC-3 timezones.
