Job description

About GreyNoise

GreyNoise Intelligence is a mission driven security startup focused on helping organizations understand and mitigate risks from Internet scanning and exploitation. GreyNoise provides real-time, verifiable 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.

The GreyNoise Global Observation Grid observes and analyzes unique threat data at-scale that no one else can. GreyNoise provides the most actionable threat intelligence against perimeter threats, so that no attack works twice.

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.

What You Will Do

• Lead initiatives related to deployment, scaling, monitoring, and enhancing the backend services, pipelines, and infrastructure supporting GreyNoise’s deception technologies.
• Work as a member of the team of engineers responsible for GreyNoise’s sensor and core networking technologies.
• Develop new capabilities to enable wider and more diverse deception profile deployment in a scalable, observable, and modular fashion, combining software engineering and infrastructure management skillsets.
• Collaborate with the GreyNoise research team to support their deception profile development efforts.
• Support development efforts on our sensor and core networking technologies using Go and Rust.
• Participate in an on-call rotation helping triage on-call tickets, prioritize and unblock team members, and guide sprint planning to drive effective execution.
• Debug and troubleshoot complex production issues across multiple systems, leveraging strong analytical skills and attention to detail.

What You Will Bring

• Proven experience leading technical projects and helping teams navigate competing priorities in a fast-paced environment.
• A structured approach to triaging issues: the ability to quickly assess, prioritize, and delegate or resolve problems during on-call rotations.
• Strong debugging skills, including the ability to diagnose and resolve complex issues across APIs, integrations, and distributed systems.
• 5+ years of production software engineering experience, including:
• Developing and maintaining high-throughput networked backend services and REST APIs
• Working with Go (Golang) for backend development.
• Managing cloud-based infrastructure using Terraform or AWS CloudFormation
• Designing and implementing CI/CD pipelines using Github Actions.
• Experience designing modular OS images and managing build artifacts
• Familiarity with containerization, process jailing, and virtual-machine isolation technologies
• Knowledge of common networking protocols and networked services
• A firm understanding of the networking layers encompassing the OSI model
• A collaborative and communicative mindset, with a willingness to engage across teams and disciplines to deliver customer value.

Nice to Haves

• Experience building integration platforms with support for external contribution.
• Experience using Rust.
• Knowledge of monitoring and logging tools to improve observability (e.g. Grafana, Honeycomb, CloudWatch).
• Experience managing event-driven application architectures using technologies like Kafka
• Awareness of anti-virus evasion techniques and how to incorporate these concepts into OS level monitoring.
• Experience with delivering data to customers through APIs, SDKs, or other data integration methods.
• Strong interest in customer success and the ability to translate technical requirements into impactful solutions.

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
