Requirements
  • Bachelor of Science (BS) in Mechanical or Aerospace Engineering from an accredited university or institution
  • Minimum of 9 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
Responsibilities
  • You will be responsible for mechanical design aspects of Cesium phased array antennas, subsystems, and interfaces through all phases of the development process.
  • 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.

Simplify's Take

What believers are saying

  • The recent $65 million Series B+ funding round led by Trousdale Ventures provides significant financial backing for expansion and product development.
  • Selection by Rocket Lab to provide multi-beam Ka-band communications payloads for the Space Development Agency's Tranche 2 Transport Layer Constellation highlights CesiumAstro's industry leadership.
  • Founder and CEO Shey Sabripour's appointment to the Texas Aerospace Research and Space Economy Consortium Executive Committee underscores the company's influence and leadership in the aerospace sector.

What critics are saying

  • The lawsuit alleging trade secret misappropriation by a former executive could lead to legal and financial repercussions.
  • The niche market of space-based radio technology is highly competitive, with only a handful of companies working at the cutting edge, increasing the pressure to continuously innovate.

What makes CesiumAstro unique

  • CesiumAstro's focus on compact, high-performance communication systems for space applications sets it apart in the aerospace market, where size, weight, power, and cost are critical factors.
  • Their modular hardware and software building blocks offer seamless integration for mission-specific payload configurations, providing a unique value proposition.
  • The company's utilization of the latest semiconductor and manufacturing technologies ensures they remain at the forefront of innovation, offering affordable solutions with a first-mover advantage.
