About Us

At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world’s largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine’s Top Company Cultures list and ranked among the World’s Most Innovative Companies by Fast Company.

At Cloudflare, we’re not looking for people who wait for a polished roadmap; we’re looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you’re the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you’ll fit right in.

About the team

Cloudflare’s mission is to help build a better internet and the Threat Application Services (TAS) team lives at the core of that effort. The team builds the automated services and systems that transform Cloudflare’s massive network telemetry into actionable intelligence. We empower customers with products to combat advanced threats, enabling them to query, investigate, and automatically mitigate attacks using Cloudflare’s unique visibility into global threat actor activity.

At a high level, the Threat Application Services team is the engineering engine within Cloudforce One. We are responsible for the end-to-end lifecycle of threat intelligence data, from ingestion and enrichment to exposing high-fidelity indicators through the Threat Events platform and high-performance APIs. Our work ensures that threat intelligence is not just a report, but a scalable, real-time defensive layer across the Cloudflare stack.

About the Role

This role is for the Senior Engineering Manager of the Threat Application Services team within Cloudforce One’s Engineering organization. You will lead a team of high-performing engineers dedicated to building and scaling the Cloudforce One Threat Events platform, our external Threat Intel APIs, and the backend systems that integrate Indicators of Compromise (IOCs) directly into products like WAF and Gateway for automated mitigation. You will also lead hiring efforts to expand our engineering capabilities as we build the next generation of agentic threat intelligence tools.

What you'll do

You will be responsible for the architectural direction and operational excellence of the services owned by your team, ensuring our intelligence platforms meet the latency and reliability requirements of Enterprise security operations. You will also drive the professional development of your direct reports and collaborate with product managers and security researchers to turn complex threat data into intuitive, automated customer experiences.

You thrive in a fast-paced environment where software engineering meets security research. You have experience delivering scalable distributed systems, managing complex data pipelines, and leading teams through the transition from "getting things done" to building world-class, reliable products.

This role may require flexibility to be on-call outside of standard working hours to address technical issues as needed.

Desirable skills and experience

• Experience with AI-assisted development and agentic AI workflows.
• Prior experience building high-performance APIs or platforms for threat intelligence, security operations, or large-scale data analytics.
• 8+ years of Software Development experience, with a focus on Go, JavaScript, or distributed systems.
• Led high-performing engineering teams for over 8 years, responsible for architectural direction and operational excellence of large-scale distributed security platforms (e.g., Threat Intel APIs, automated mitigation systems). Proven ability to manage technical debt, drive professional development through strong mentorship, and excel at planning and execution to deliver predictable, world-class products in a high-growth environment.
• Proven experience leading engineering teams and managing technical debt in a high-growth environment.
• Understanding of the Cyber Kill Chain and how to automate the ingestion and distribution of IOCs (IPs, domains, hashes, JA3/4 fingerprints).
• Experience with edge computing (e.g., Workers), SQL-at-the-edge (D1/SQLite), and building systems that scale to handle trillions of signals.
• Excel at planning and execution to deliver predictable, reliable features for security teams.
• Strong mentorship and coaching skills to support the career growth of engineers in a specialized security engineering domain.

Compensation

Compensation may be adjusted depending on work location.

• For Washington, DC based hires: Estimated annual salary of $220,000 - $303,000

What Makes Cloudflare Special?

We’re not just a highly ambitious, large-scale technology company. We’re a highly ambitious, large-scale technology company with a soul. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we've equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work, technology already used by Cloudflare’s enterprise customers--at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we've provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure and privacy-centric public DNS resolver. This is available publicly for everyone to use - it is the first consumer-focused service Cloudflare has ever released. Here’s the deal - we don’t store client IP addresses never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
