FEED

Examples of previous intern projects include designing, building, testing, and running: flexible blind-mate ducting connection between an aircraft and a ground-based cooling station, allowing for aircraft battery temperature regulation during charging and pre-flight preparation. Mechanical Engineers at Zipline go deep in their area of ownership, become experts in the problem domain, define requirements for their systems, rapidly develop creative and simple solutions, and prove with testing that their system meets the rigors and edge-cases of real-world deployment.

Senior Mechanical Engineer - Test Infrastructure

Our portfolio includes over 100 LEED Platinum projects as well as dozens of projects that have either achieved or are pursuing the Living Building Challenge, Passive House, Architecture 2030, Carbon Neutral, Net Zero Energy, and Net Zero Water. In this pivotal role, you will transition from individual design work to high-level project oversight, providing the engineering direction and mentorship necessary to bring complex projects from initial concept through final construction.

PAE Consulting Engineers Inc

Lead Mechanical Engineer

You will play a key role in turning prototypes into reliable, manufacturable products, working hands-on with early designs and suppliers to ensure quality and scalability. This role is ideal for an engineer excited about working across the full product lifecycle — from whiteboard sketches and 3D CAD to testing, validation, and manufacturing handoff.

Senior Antenna Design Engineer

We're starting with an approach that we believe can help the most people the fastest, and also allow us to learn as much about the brain as possible: developing a non-invasive, ultrasound-based device that can stimulate and image the brain at high resolution and depth. We hire people who are exceptional at their craft, believe hard things are worth doing, and execute relentlessly — people who expect the highest levels of both rigor and integrity from each other.
