About the Team DoorDash's Protective Services function safeguards executives, their families, and residences through executive protection, residential security, threat management, and secure transportation across a three-brand global enterprise. The team operates 24/7 and is built on the principle that protection starts before an incident, not after. The people who do this work well combine operational discipline with personal composure, take ownership of outcomes rather than tasks, and represent the program in every interaction with the principal population. About the Role The Protective Services Agent provides close protection for DoorDash executives and their families across all operating environments, including corporate headquarters, domestic and international travel, company events, and residential settings. The role requires a trained executive protection professional who develops and implements security plans, conducts advances and risk assessments, coordinates with law enforcement and venue partners, and serves as the principal's primary security presence. Personnel must be capable of managing incidents and serving as first responders on scene. Operations regularly involve extended duty periods, irregular schedules, and short-notice deployments. Potential travel up to 25% of the time. You are excited about this opportunity because you will… Provide close protection across all principal environments.

At Lyft, our purpose is to serve and connect. We aim to achieve this by cultivating a work environment where all team members belong and have the opportunity to thrive. The strongest enterprise and mid-market marketing doesn't lead with a product — it leads with the problem a buyer already has. A hospital administrator isn't looking for "Lyft Concierge"; they're looking to reduce missed appointments. An auto dealer principal isn't looking for a rideshare product; they're looking to keep loaner logistics from costing them revenue. We are in the process of revising our go-to-market for Lyft Business to organize around these audiences and their transportation problems, with Concierge, Lyft Pass, Business Profiles, and our Business Travel products positioned as the answer to a clearly named pain point by customer profile. We're hiring an Industry Marketing Manager to build that audience-first structure for our priority verticals, starting with Healthcare and Automotive , across both mid-market and enterprise segments. You'll own the vertical narrative and the content, demand generation strategy, and enablement that will drive marketing-attributable revenue. The primary function of this role is to build and lead vertical-specific go-to-market (GTM) motions for our mid-market and Enterprise business — bringing together vertical-specific content, demand generation, and sales enablement into a coherent, audience-first strategy. Responsibilities: Own vertical strategy and integrated programs Design and execute large, orchestrated tentpole programs for our priority verticals (no more than 2 per quarter) — multichannel activation spanning digital, live events, paid media, social, and press — that bring our value proposition and industry point of view to life for a defined buyer (e.g., hospital CFO, healthcare operations leader, dealer principal/service manager). Build and maintain a thought leadership agenda for each prioritized vertical: original research, proof p
