Mechanical Engineer - Imaging Payloads

Urban Sky•Quinte West, ON

3d•Onsite

About The Position

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.

Requirements

Must be US Citizen or Permanent Resident
Must be located near Denver, CO
3+ years of design engineering experience, preferably including substantial hands-on work
Highly proficient at Electrical System Design
Integrated/embedded electronics design experience

Nice To Haves

Bachelor’s degree in Mechanical Engineering or a closely related discipline; advanced degree is a plus but not required
2-5 years of experience in mechanical design and integration of electromechanical systems operating in real-world environments
Proficiency in CAD software (e.g., OnShape, SolidWorks, or Fusion 360) for designing complex mechanical systems
Strong knowledge of materials and manufacturing processes, including CNC machining, sheet metal fabrication, 3D printing, and injection molding
Intuitive understanding of tolerance analysis, design for manufacturing (DFM), and design for assembly (DFA), with the ability to design parts and assemblies that are practical to build, inspect, and maintain
Strong analytical and problem-solving skills, with experience using hand calculations and simulation tools to inform design decisions and the ability to systematically troubleshoot hardware issues when things don't go as planned

Responsibilities

Translate product requirements and use cases into ruggedized design solutions for a diverse customer base spanning scientific, commercial, and defense applications
Design robust, reusable payload structures with an emphasis on protecting critical components and enabling rapid turnarounds between flights. Perform structural analysis and testing to validate designs against flight load cases
Select materials appropriate for stratospheric conditions balancing strength, thermal performance, weight, and cost constraints
Support the design and development of 2-axis gimbal systems including structure design, motor and gear reduction mechanism selection, and feedback architecture to achieve precise pointing control
Design and analyze thermal management solutions to maintain components within operating temperature ranges across stratospheric conditions. Develop and verify thermal models against test and flight data to build confidence in system performance
Plan and execute benchtop testing of subsystems and prototypes to validate functionality prior to flight testing
Conduct environmental testing including thermal cycling, vacuum exposure, and shock qualification. Support field integration and test campaigns, incorporating operational feedback into design iterations
Maintain thorough engineering documentation including design/analysis rationale, trade studies, assembly procedures, test reports, and lessons learned to support knowledge retention and production readiness
Generate high-quality engineering drawings with appropriate use of GD&T when necessary
Develop and execute verification and validation plans, prepare prototypes for flight, and maintain flight safety documentation
Analyze flight performance data to identify issues and drive design iteration. Lead post-flight hardware teardowns and failure investigations to determine root cause and inform corrective actions
Contribute to payload architecture decisions, including evaluating new sensor technologies, identifying candidate hardware for integration, and proposing new payload concepts or capability expansions
