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 Staff Mechanical Engineer, you will lead mechanical design efforts across all phases of product development, from initial concept through field support. You will be responsible for designing and optimizing mechanical systems for Cesium's aerospace products, working across the full lifecycle: requirements definition, detailed design, simulation, analysis, manufacturing, testing, qualification, and customer support.
Key responsibilities include:
- Developing mechanical designs with expertise in electronics packaging, thermal management, and precision machining
- Conducting thermal, shock, vibration, and stress simulations and analyses
- Performing finite element analysis (FEA) and cost analysis to validate and optimize designs
- Applying EMI/EMC mitigation techniques and environmental compatibility analysis
- Ensuring compliance with MIL-STD-810 and DO-160G standards
- Presenting engineering design review materials to customers and leadership
- Participating in proposal-writing efforts
- Collaborating closely with electrical engineers and cross-functional teams
You will work in a dynamic startup environment with hands-on, interactive, and autonomous work opportunities. Excellent written and verbal communication skills are essential for customer and leadership engagement.
REQUIREMENTS:
- BS or MS in Mechanical Engineering, Aerospace Engineering, or related technical field
- Minimum 12 years of industry experience in design and analysis of avionics or ruggedized embedded electronics packaging (including thermal, vibration, and stress dynamics) OR aircraft structures and mechanisms (Master's degree may count as two years of experience)
- Proficiency in CAD software (SolidWorks) and professional mechanical/FEA tools (Ansys)
- Experience with CNC manufacturing
- Expertise in thermal management design, precision machining principles, thermal and shock/vibration simulation and analysis
- Knowledge of GD&T (geometric dimensioning and tolerancing)
- Familiarity with electronics assemblies and experience working with electrical engineers
- Experience with design for test, manufacturability, assembly, and reliability
- 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
