About the Role

<div class="content-intro">About Urban Sky:  Urban Sky is a venture-backed aerospace startup that pioneers utilization of the stratosphere and reimagines the way humans view and analyze the earth. We design, build, operate, and sell stratospheric balloon systems, and the data we collect supports a wide range of applications, from real-time wildfire monitoring to urban mapping. Our technology is also employed by government customers including the Department of Defense (DoD), NASA, and others. Urban Sky sends flight vehicles to the stratosphere on a weekly basis.  Our team consists of engineers, makers, developers, and doers who believe in the power of human potential when passion meets utility within a small, supportive team. At Urban Sky we strive to create a team culture grounded in candor, inclusion, respect and empowerment.  We aim to build the next chapter of stratospheric history in Denver and are seeking self-starting, open-minded, and hard-working team members. </div>About The Role:  Urban Sky is seeking a talented Mechanical Engineer to own the design, development, and fielding of advanced electro-optical imaging systems aboard our stratospheric balloon platforms. Our payloads operate in one of the harshest environments on Earth. They must survive temperature extremes, near-vacuum pressures, and high shock loads while delivering precision performance. This engineer will design systems that integrate optics (both custom and off-the-shelf), sensors, edge compute, 2-axis stabilization mechanisms, and thermal management systems into compact, flight-ready packages.  The technical challenges are broad, and so is the ownership. This is a hands-on role on a fast-paced, multidisciplinary team. Your work will span the entire development lifecycle, from initial requirements and rapid prototyping through flight testing and production transition. You will work across a range of commercial and defense products that are making real and lasting impacts today.  Key Responsibilities:  <ul> <li data-leveltext="" data-font="Symbol" data-listid="36" data-list-defn-props="{"335552541":1,"335559685":720,"335559991":360,"469769226":"Symbol","469769242":[8226],"469777803":"left","469777804":"","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Translate product requirements and use cases into ruggedized design solutions for a diverse customer base spanning scientific, commercial, and defense applications </li> <li>Design robust, reusable payload structures with an emphasis on protecting critical components and enabling rapid turnarounds between flights.
