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 Senior Mechanical Engineer I to our Mechanical Engineering team. If you 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 design aspects of Cesium phased array antennas, 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 antennas and payloads.

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.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

Bachelor of Science (BS) in Mechanical or Aerospace Engineering from an accredited university or institution

Minimum of 4 years of experience in space antenna and payload mechanical engineering to include electronics packaging, thermal, shock, vibration, stress dynamics, and cost. A Master's degree may count as two years of experience.

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 Ansys Mechanical, SolidWorks Simulation, and Thermal Desktop

Experience with CNC manufacturing and GD&T

Experience with advanced aerospace manufacturing and materials including sandwich panels and carbon composites, OR experience with high-reliability deployment mechanisms for space applications (including deployment, HDRMs, power delivery, etc.).

Proficiency in detailed mechanical design (3D CAD, drawings, etc.)

Experience designing and manufacturing mechanisms and mechanical actuators

Experience with EMI/EMC mitigation techniques

Familiarity with satellite thermal architectures including heat pipes, phase change materials, contact resistance, and surface finishes as well as fundamental understandings of orbital thermal control in a LEO environment.

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

PREFERRED EXPERIENCE

Python, C++, or other programming languages

Experience with large, deployable antenna arrays which drive your vision for the next generation of on-orbit communications and sensor arrays.

Robotics and control systems experience

PCBA experience.
