About The Role

As a Senior Product Manager, Client-Side Security at Cloudflare, you will be responsible for building products that improve the way that the Internet works. Product Managers at Cloudflare shape high-level product goals but also get our hands dirty. On an average day, you might pitch a concept to senior leadership, collaborate with marketing, work with designers to conduct user research, prototype a new feature, iterate on a spec, analyze usage data, and pair with an engineer on implementation.

We are seeking an innovative and customer-centric Senior Product Manager, Client-Side Security to own the vision, strategy, and execution of our client-side security offering, also known as Page Shield. Unlike server-side security, which focuses on protecting the server and backend infrastructure, client-side security focuses on identifying threats for the browser environment, such as malicious scripts. In the role, you will define product requirements, prioritize features, and drive the roadmap for Page Shield capabilities. Your role involves understanding the evolving threat landscape, translating complex security challenges into intuitive solutions, and ensuring our products deliver measurable protection and business value. You will engage with customers and internal teams to create solutions, gather feedback, and communicate product impact, helping Cloudflare stay ahead in client-side security innovation. You will also work closely with the Sales organization to support strategic sales motions, drive targeted campaigns, and expand customer adoption of the product.

You will:

• Own your space. You will own the priorities and scope for a high performing engineering team focusing on detecting client-side threats.
• Connect the pieces. Product managers are a nerve center at Cloudflare, responsible for connecting engineering, program management, marketing, revenue, and partners to make sure that our ships go out on time and with the maximum impact.
• Excel across teams. Enterprise capabilities cut across all of our product verticals, so you should be comfortable working with product managers across the company to prioritize systemic improvements that our enterprise customers need.
• Be customer obsessed. You will be responsible for directly engaging with customers and understanding how they use our products. You’ll bring these insights back to the team to build a great roadmap. Join pre-sales and post-sales calls with customers, sales, support, etc., to assist with, and help understand all phases of the customer lifecycle.
• Be data driven. You should be comfortable working with data, and analyzing data to quantify the impact of problems and opportunities in your space.

Key Qualifications And Skills

• 5+ years of experience as a product manager, technical program manager, or equivalent delivering solutions in the cloud at scale for a technical audience.
• Customer focus. At Cloudflare, we serve the needs of customers large and small, and our product managers need to be comfortable understanding how to design for enterprises without compromising the experience for individuals and small businesses.
• Technical Acumen. The ability to grasp complex technical concepts ( ideally in the security, cloud infrastructure, or SaaS space). You must be comfortable engaging in deep technical discussions with engineering teams.
• Knowledge of web technologies. You have experience or understanding of how browsers render pages, how JavaScript and third-party scripts execute, and how web APIs interact with backend services.
• Data-Driven: You ground your decisions in data and qualitative user feedback, with a relentless focus on solving real-world problems for security operators and platform administrators.
• (Optional but preferred) Experience in cloud security, browser security, or enterprise SaaS products; knowledge of regulatory/privacy requirements affecting client-side data (e.g. PCI DSS v4.0).

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.
