Job DescriptionAbout Pair Team Pair Team is building a new kind of healthcare system across Medicaid, Medicare, and public assistance programs: one that recognizes that access to housing, nutritious food, and reliable transportation are just as critical to health as having the right medications or seeing a doctor. As a public benefit corporation and AI-enabled medical group, we partner with shelters, food pantries, and community organizations to deliver "whole-person" care to the 115 million Americans who rely on the safety net. We are currently the largest complex care provider in California with over 500 employees and are expanding nationally. Our model replaces fragmented healthcare and social services systems with one trusted relationship for all medical, behavioral, and social needs. We improve access, build trust, and dramatically lower costs (52% fewer ER visits, 26% fewer hospitalizations). Our model is a rare combination of saving tax payer dollars ($150B annually at scale) while putting people on an upward life trajectory. At national scale, this approach would save taxpayers. These outcomes are driven by the AI-first, whole-person infrastructure we are building — a platform that connects healthcare and social-service organizations into a unified network.

Job DescriptionAbout Zipline Do you want to change the world? Zipline is on a mission to transform the way goods move. Our aim is to solve the world's most urgent and complex access challenges by building, manufacturing and operating the first instant delivery and logistics system that serves all humans equally, wherever they are. From powering Rwanda's national blood delivery network and Ghana's COVID-19 vaccine distribution, to providing on-demand home delivery for Walmart, to enabling healthcare providers to bring care directly to U.S. homes, we are transforming the way things move for businesses, governments and consumers. The technology is complex but the idea is simple: a teleportation service that delivers what you need, when you need it. Through our technology that includes robotics and autonomy, we are decarbonizing delivery, decreasing road congestion, and reducing fossil fuel consumption and air pollution, while providing equitable access to billions of people and building a more resilient global supply chain. About the Team and the Role The Ground Systems team is responsible for all of the hardware on the ground that enables our Zips to take off, fly, land and prepare for their next mission. We are developing a ubiquitous infrastructure solution for drone-based logistics, akin to what the solar industry has achieved with solar panels deployed worldwide. Our goal is to develop elegant integration solutions that are modular, cost effective, and adaptable to both new and existing building structures and sites worldwide for a variety of customers making drone deliveries. Our team designs large steel towers that hold our docks. Outside of providing structural support, the towers include the mechanisms, actuators, and harnessing that support our docks' charging infrastructure and transmit data.

This will be centered around welded steel towers that are a few stories high. We're looking for an engineer that does not let "how it is normally done" artificially limit the potential solution space, by leveraging experiences, knowledge, and first principles thinking towards problem solving to create an optimal product. Physical scale does not daunt you, whether the mechanism fits within your hand or is 10 meters long, you will engineer systems that will only come together days before they are needed, so we're counting on you to make sure they work the first time. You are comfortable solving complex problems with little direction and maximum autonomy. Hand calcs guide your thinking and designs and help you quickly bound a problem. We are looking for an experienced mechanical engineer to own the design of the entire system and subassemblies for the next generation of our towers. This will include design of structural components, mechanisms, and electronics integration. As a member of our core design team, you will make important decisions about the product architecture and create designs that will enable practical scale on a short timeline that will meet high product reliability targets. You will quickly iterate and downselect based on data from your analysis and test results from your prototypes. Collaboration cross functionally will be key with electrical, software, civil, NPI and supply chain teams to bring your designs to production and into the field. What You'll Bring • Proven track record owning complex subassemblies or full systems over at least 3 product programs (concept, prototype, validation, production), • Strong fundamentals: load estimation, classic mechanics, structural hand calcs to guide part sizing, FEA and clean CAD designs., • Excellent problem solving - you are tenacious and scientific in your approach while able to quickly explain concepts to others, • Familiarity with mechanism design and the integration of electrical components into hardware products, • Practical knowledge of manufacturing methods such as welding, sheetmetal forming, extrusion, CNC machining, etc, • Experience partnering with contract manufacturers to ramp up production of high volume lines, • Demonstrated CAD fluency for system level ownership - 3D/2D of 20-50 parts simultaneously, • Disciplined processes: Your parts are released, BOMs are maintained, SOPs created for builds, and timelines are up-to-date, • You have true expertise in one area that will level up the team, • Excellent communication - written, verbal, and visual. You know how to tailor to your audience with the right level of technical depth to be as effective as possible, including using basic tools in place of full CAD when it makes sense, • Bachelor's degree in Mechanical Engineering, • Ability to periodically (<10%) travel to visit customers and suppliers, • NX is your primary CAD tool, • Knowledge in applying appropriate FOS and margin to human safety critical application (design margin tables, structural joint calculations) Zipline is an equal opportunity employer and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local laws or our own sensibilities. We value diversity at Zipline and welcome applications from those who are traditionally underrepresented in tech.
