Company Details


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.

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

In this position, you will be responsible for mechanical aspects of Cesium spacecraft, subsystems, and interfaces through all phases of the development process. The ideal candidate will be versatile and proficient in mechanical analysis, electronics packaging, computer-aided design (CAD), mechanical interfaces, thermal architecture, spacecraft propulsion, deployable and actuated structures, and environmental qualification of spacecraft.

As a Cesium spacecraft team member, you will work on a small team to develop satellites and put them in orbit. You will be responsible for mechanical designs from concept through space flight including requirements definition, architecture trades and block diagrams, analysis, manufacturing, testing, qualification, and in-orbit support.

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


 Successful candidates will require, as a minimum:

  • Bachelor of Science (BS) in Mechanical or Aerospace Engineering from an accredited university or institution
  • Minimum of 1 year of industry or university research experience (including CubeSat projects) in spacecraft mechanical engineering to include electronics packaging, thermal, shock, vibration, stress dynamics, and cost.
  • Experience in conducting architectural trade studies including parametric and first-order cost and physical analysis
  • Experience with professional mechanical and FEA CAD tools, such as SolidWorks Simulation and Thermal Desktop
  • Experience with CNC manufacturing and GD&T
  • Proficiency in detailed mechanical design (3D CAD, drawings, etc)
  • Experience designing and manufacturing mechanisms and mechanical actuators
  • Familiarity with launch and LEO environments (thermal, shock, vibe, radiation, etc)
  • Familiarity with design for test, manufacturability, assembly, and reliability
  • Excellent written and verbal communication skills
  • Experience with advanced aerospace manufacturing and materials including carbon composites

Preferred experience includes:

  • Python, C++, or other programming languages
  • Experience with two or more spacecraft structural and mechanical architectures which drives your vision for the next generation of spacecraft
  • Satellite experience ranging from CubeSat to large satellites
  • Robotics and control systems experience
  • Spacecraft propulsion system experience
  • Gyroscopic system experience
  • PCBA experience
  • Familiarity with spacecraft thermal architectures including heat pipes, phase change materials, contact resistance, and surface finishes as well as fundamental understandings of thermodynamics in a spacecraft context

The salary range for this role is $70,000 to $85,000; however, CesiumAstro considers several factors when extending an offer, including but not limited to, the role and associated responsibilities, a candidate’s work experience, education/training, and key skills. We also provide generous benefits and stock option packages to all our employees.

CesiumAstro is proud to be an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, pregnancy, sexual orientation, gender identity, national origin, age, protected veteran status, or disability status.
