CesiumAstro develops cutting-edge communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. The Skylark product line focuses on rapid design, build, and test of active phased array antennas (AESA) for terrestrial and airborne applications, spanning high-power ground terminals for missile defense to commercial airline and helicopter connectivity solutions.
As a Senior Mechanical Engineer, you will own mechanical designs of CesiumAstro products through all phases of the development process—from initial concept design through requirements definition, detailed design, simulation, analysis, manufacturing, testing, qualification, and field support. You will be responsible for thermal management design, precision machining principles, thermal and shock/vibration simulation and analysis, EMI/EMC mitigation, environmental compatibility analysis, geometric dimensioning and tolerancing (GD&T), finite element analysis (FEA), and cost analysis to develop, validate, and optimize mechanical designs.
Key responsibilities include:
- Mechanical design of electronics packaging, with proficiency in aircraft mechanical interfaces and environmental qualification (MIL-STD-810, DO-160G)
- Presenting engineering design review materials to customers and leadership
- Participating in proposal-writing efforts
- Cross-functional collaboration with electrical engineers and manufacturing teams
You will work in a dynamic, startup environment with hands-on, interactive, and autonomous work. Excellent written and verbal communication skills are essential.
REQUIREMENTS:
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related technical field
- Minimum 5 years of industry experience in design and analysis of avionics or ruggedized embedded electronics packaging (thermal, vibration, stress dynamics) OR aircraft structures and mechanisms (Master's degree may count as 2 years)
- Familiarity with electronics assemblies and experience working closely with electrical engineers
- Familiarity with design for test, manufacturability, assembly, and reliability
- Proficiency with CAD software (e.g., SolidWorks)
- Experience with professional mechanical and FEA CAD tools (e.g., Ansys)
- Experience with CNC manufacturing
- Experience with EMI/EMC mitigation techniques
- Excellent written and verbal communication skills
PREFERRED EXPERIENCE:
- Aerospace industry design, development, and qualification
- Proven experience as a technical lead on a program or project
- Experience with aircraft/airframe integration
- Experience with FAA certification to DO-160G requirements or environmental qualification to MIL-STD-810 requirements
