Engineering Manager, Browser Run

Available Locations: Lisbon

Emerging Technologies & Incubation (ETI) is where new and bold products are built and released within Cloudflare. Rather than being constrained by the structures which make Cloudflare a hugely successful business we are able to leverage them to deliver entirely new tools and products to our customers. Cloudflares edge and network make it possible to solve problems at massive scale and efficiency which would be impossible for almost any other organization.

We build the tooling and platform capabilities that power the next generation of AI agents on the Cloudflare Developer Platform. Our goal is to make it easier for agents to interact with the web and to be observed and controlled while they do it without giving up performance scalability or security.

Browser Run is the centre of that work and it is the product this role owns. It runs full browser sessions on Cloudflares global network and lets developers drive them with code or with an agent: a Chrome DevTools Protocol endpoint that any Puppeteer Playwright or CDP client can connect to from anywhere Workers bindings and a REST API for the common jobs screenshots PDFs Markdown extraction scraping and crawling. On top of that sit session recording and replay live debugging and a path for a human to step in when an agent gets stuck.

It is used by external developers building agents crawlers and scrapers and by other Cloudflare teams who need a browser they can trust. It is also a billed product on a steep growth curve which makes capacity cold-start latency concurrency limits and abuse protection product problems rather than merely operational ones.

The teams wider portfolio includes an agent-first browser built on Workers rather than containers a managed CI platform for the agent development lifecycle visual regression testing delivered as a service a pre-rendering service URL Scanner and CDNJS. Browser Run is the focus of this role today; there is scope for more of that portfolio to come into it as the role and the team grow.

Browser Run went from an internal rendering tool to a public billed product and the surface has not stopped moving the CDP endpoint MCP client support session replay and the REST API all landed inside a year. That pace is the point and it is the thing this role has to make sustainable.

We are a tight-knit team that communicates and collaborates regularly. We celebrate our achievements support each other when we make mistakes and hold each other and our work to the highest standard.

This is a hands-on engineering management role. You will own Browser Run engineering end to end the people the roadmap the reliability and the story we tell customers about it. You will report to the Senior Engineering Manager for AI Agents Tooling & Platform and partner closely with Product Management Developer Relations and platform teams across Cloudflare.

Browser Run is the primary focus. The team owns other products and there is scope for some of them to move into your remit as the role and the team grow but we are hiring someone to make Browser Run excellent first.

You will not be writing most of the code. You will be expected to understand it well enough to review a design document challenge an architecture and know when an estimate is wrong.

• Manage coach and grow the team of systems engineers behind Browser Run 1:1s career development performance conversations and hiring.
• Own the Browser Run roadmap and delivery and give the team and the wider organisation clear visibility into what is being worked on in what order and what we are deliberately not doing.
• Partner with Product Management to set direction: shape the roadmap pressure-test scope and make the trade-off calls that keep an incubation product shipping.
• Own Browser Runs operational health browser fleet capacity session reliability cold-start latency concurrency limits on-call rotations alert quality and incident follow-through. External developers and other Cloudflare teams depend on this service.
• Keep the automation surface honest: Puppeteer and Playwright compatibility CDP behaviour that matches what developers expect from a local Chrome and a credible story for Chrome version upgrades.
• Develop leaders. Identify and grow the engineers who will run day-to-day delivery for an area of the product and hand that work to them.
• Resolve cross-team dependencies with the Workers Developer Platform Security and Billing teams and bring contentious technical decisions to closure quickly and calmly.
• Own the commercial mechanics of a billed service including the unglamorous parts: usage metering quotas plan limits abuse protection and pricing input.
• Represent Browser Run externally through launch blog posts developer documentation conference talks and direct customer conversations.

We want you to love it here. This role is a great fit for you if:

• You have run an engineering team that shipped and you can point at what it shipped.
• You give your technical legos away. Your measure of success is the teams output and the growth of the people on it not your own commit history.
• You are comfortable with ambiguity. Incubation means the requirements move and you can change direction without drama.
• You are direct. You give feedback early disagree openly and admit when you were wrong.
• You write well. You believe a clear design document roadmap or incident report is as much of a deliverable as the code.
• You care about operational quality and treat a noisy alert as a bug not as background noise.
• You find browsers genuinely interesting as an engineering problem how Chrome behaves under load why automation breaks and what an AI agent actually needs from a browser it does not own.
• You want to join a team that upholds a culture of support open and honest communication and collaborative problem-solving.

• 2 years managing engineering teams on top of a solid track record as a hands-on engineer.
• Experience owning a production service end to end including on-call rotation capacity planning and incident review.
• Demonstrated experience growing engineers promotions you supported and ideally a team lead or first-line manager you developed.
• Hands-on familiarity with browser automation Chrome DevTools Protocol Puppeteer or Playwright or with the browser internals underneath them.
• Strong technical grounding in distributed systems web platform fundamentals (HTTP JavaScript execution models rendering) or cloud infrastructure enough to hold a credible design review.
• A track record of partnering with Product Management to set and defend a roadmap including saying no.
• Excellent written communication for internal and public-facing technical content.
• Experience hiring: writing job descriptions running interview loops calibrating a panel and closing candidates.

• Experience running headless browser infrastructure at scale browser fleet management sandboxing and resource isolation.
• Experience shipping AI or agent-facing platform primitives such as MCP servers tool-calling surfaces or agent orchestration.
• Familiarity with the Cloudflare Workers development platform: Workers Durable Objects Workflows R2 D1.
• Experience taking an internal tool to a billed external product including usage metering and pricing.
• Experience managing a distributed team across time zones.
• Open source maintainership or a public body of technical writing.

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 weve 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. Heres the deal - we dont 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.
