Principal Mechanical Engineer Advanced Technology Development
ROLE OVERVIEW
Echodyne is seeking a PrinIcipal Mechanical Engineer to join the Advanced Technology Development team and lead mechanical architecture and design for rapid radar prototypes, electronics packaging, thermal solutions, test infrastructure, and early system integration.
You will join a high-performing, cross-disciplinary team where senior engineers have meaningful technical ownership, run fast experiments, and see their work move directly into future radar products. You will work on prototype development, including tiled-aperture integration, thermal management for high-power electronics, calibration infrastructure, and a packaged radar demonstrator for field learning.
The ideal candidate combines hands-on mechanical design depth with sound technical judgment, fast prototype execution, and the discipline to preserve a practical path from early hardware to reliable, producible products.
RESPONSIBILITIES
Lead mechanical development for prototypes, testbeds, demonstrators, and future Advanced Technology Development efforts
Develop electronics packaging, enclosure, radome, mounting, handling, and installation concepts for advanced radar hardware
Design thermal solutions for RF assemblies, high-power electronics, compute hardware, and compact radar configurations
Collaborate with RF, electrical, PCB design, systems, test engineering, manufacturing, suppliers, and key stakeholders to deliver mission-critical prototype solutions within demanding performance and timeline goals
Create parts, assemblies, fixtures, and integration hardware using rapid machining, sheet metal, additive manufacturing, and quick-turn supplier capabilities
Apply modern best-practices and establish practical guidance for reliability, design for manufacturing (DFM), design for assembly (DFA), tolerance control, and prototype-to-product transition
Lead ad-hoc peer reviews, supplier engagement, hands-on assembly, test, troubleshooting, and aid in the transfer of mechanical concepts into product development
REQUIRED SKILLS / EXPERIENCE
Strong hands-on experience designing mechanical hardware for electronics, embedded systems, RF systems, or other complex technical products across the development lifecycle
Experience with electronics packaging, enclosure and radome design, thermal management, mounting structures, environmental protection, and prototype integration
Advanced proficiency with a mechanical CAD platform such as SolidWorks, Creo, or NX, including production drawings, geometric dimensioning and tolerancing, and configuration control
Experience designing parts and assemblies for machining, sheet metal, additive manufacturing, and fast supplier builds
Practical understanding of heat paths, heat sinks, airflow, conduction cooling, interface materials, and the thermal constraints of high-power electronics, including proficiency in FEA and CFD simulation software (such as ANSYS) to evaluate designs and solutions
Ability to balance mechanical, electrical, RF, PCB, manufacturing, reliability, and field-use constraints with cross-disciplinary teams
Ability to lead technical reviews, make sound design tradeoffs, and communicate mechanical risks and recommendations clearly
DESIRED SKILLS / EXPERIENCE (Looking for one or more as a complement to the core skills)
Experience developing mechanical hardware for radar, phased arrays, aerospace, defense, autonomous systems, or other high-reliability and mission-critical products
Experience in advanced development, applied research, rapid prototyping, or early hardware technology maturation
Experience packaging RF electronics, tiled apertures, antennas, precision interconnects, high-power subsystems, or environmentally exposed electronics
Experience applying design for manufacturing and assembly principles with machine shops, contract manufacturers, and production teams
Experience with tolerance analysis, environmental testing, and design verification
QUALIFICATIONS
BS in Mechanical Engineering or a related technical field and at least 12 years of relevant mechanical hardware development experience, or equivalent experience
Eligibility to handle export-controlled technical data, including ITAR- and EAR-controlled information
Echodyne’s technology is export controlled by the U.S. Government and we must evaluate an applicant’s eligibility to handle export-controlled information or obtain required Government authorizations. Therefore, we will ask you as part of the application process to identify whether you are a U.S. Citizen or green card holder, or have asylum/refugee status in the U.S.
