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 US based 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.
Please see the specific job description for all international position locations.
What You Will Do
Lead initiatives related to deployment, scaling, monitoring, and enhancing the backend services, endpoint software, 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 that power our global honeypot network with near-realtime delivery of packet captures.
Develop new capabilities to expand the sophistication of GreyNoise's attacker behavior observation and analysis.
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
Experience building control plane networking software on Linux
Familiarity with routing, traffic shaping, and modern VPN technologies for Linux
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 utilizing Gaussian Triage methodologies.
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.
Familiarity with containerization, process jailing, and virtual-machine isolation technologies.
A deep 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, Datadog, 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
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. This will be 100% matched and vested from day 1
Flexible paid time off. 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 an Apple Mac laptop and a $500 stipend for any equipment accessories.
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.
Why You Should Work at GreyNoise
You enjoy identifying and solving hard problems
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
You want to directly impact users
You want to grow beyond your current skill set
