Job description

Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.

At CesiumAstro , we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

The Skylark product line is focused on the rapid design, build, and test of cutting-edge active phased array antennas (AESA) for terrestrial and airborne applications. Current programs span high-power, large-scale ground terminals for missile defense to commercial airline and helicopter connectivity solutions.

We are looking to add a Senior Mechanical Engineer to our team. If you are great at what you do, enjoy working in a startup environment, and are passionate about developing leading-edge hardware for satellites, spacecraft, and aerospace systems, we would like to hear from you.

In this position, you will be responsible for mechanical designs of CesiumAstro products through all phases of the development process. The ideal candidate will be proficient in electronics packaging design, mechanical simulations and analyses, computer-aided design (CAD), aircraft mechanical interfaces, and environmental qualification of electronic assemblies (MIL-STD-810 and DO-160G).

As a CesiumAstro mechanical team member, you will be responsible for mechanical designs from initial concept design through requirements definition, detailed design, simulation, analysis, manufacturing, testing, qualification, and field support of Cesium's products. Required skills and experience include thermal management design, precision machining principles, thermal simulation and analysis, shock and vibration simulation and analysis, electromagnetic interference/compatibility (EMI/EMC) mitigation techniques, environmental compatibility analysis, geometric dimensioning and tolerancing (GD&T), finite element analysis (FEA), and cost analysis to develop, validate, and optimize mechanical designs.

The successful candidate will also present engineering design review materials to our customers and leadership team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.

Job Requirements And Minimum Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related technical field.
• Minimum of 5 years of industry experience in design and analysis of avionics or ruggedized embedded electronics packaging, including thermal, vibration, and stress dynamics or in aircraft structures and mechanisms.A Master’s degree may count as two years of experience.
• Familiarity with electronics assemblies and experience working closely with electrical engineers.
• Familiarity with design for test, manufacturability, assembly, and reliability.
• Experience with CAD software packages, such as SolidWorks.
• Experience with professional mechanical and FEA CAD tools, such as 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.
