About the role

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.

On the CesiumAstro Specialty Engineering Team, we are responsible for performing specialty  analysis and test across a range of disciplines including component, radiation, materials and process, reliability, and EMI/EMC engineering to support all CesiumAstro products including cutting-edge space electronics. We own specialty requirements for our designs from initial concept through manufacturing, test, and delivery, all the way through on-orbit support and anomaly analysis. Designs encompass the full spectrum of electronics design, including high-speed digital, power electronics, and RF hardware – often on the same board. 

 

We’re looking for summer interns to support our mission. Interns work side-by-side with staff specialty engineers contributing to the company’s success is as high of a priority as learning and gaining experience. All intern assignments directly support our active space electronics design; no paper intern projects which never get built! Specific assignments will be determined by a mix of project availability and candidate interests. 

 

A brief overview of work scope for each discipline: 

  1. Radiation Engineer 

CesiumAstro radiation engineers provided end-to-end support to our mechanical and electrical engineering teams.  Assignments will vary from natural space radiation environment definition and shielding to component performance to circuit analysis of single event effects. 

  1. Component Engineer 

CesiumAstro component engineers assist electrical engineering designers in identifying components which meet both electrical performance requirements and survive the harsh environment of space while balancing cost and lead time constraints.  Assignments will vary from building data integration tools and optimizing bill-of-material costs to assessing component performance and reliability. 

 

If you are an electrical engineering, physics or similar discipline student who loves your coursework and wants to sink your teeth into the rigor of space electronics design, this is the job for you.

As a GNC Intern, you will support the development of our in-house satellite, Element, by analyzing future satellite and constellation missions to drive technology roadmaps and business plans. This will be a project-based internship where you will get the opportunity to work on a space mission analysis assignment. You will work closely with CesiumAstro engineers on orbit design, mission analysis, system trades, and subsystem interactions. Interns will have the opportunity to contribute directly to CesiumAstro’s spacecraft programs through Element GNC analysis as well.    During the program, interns will present their work to peers, mentors, and Cesium executive leadership. As such, strong communication skills are essential. 

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
  • Current enrollment in a Bachelor of Science (BS), Master of Science (MS), or PhD program in Electrical Engineering or Computer Engineering from an accredited university.
  • Strong fundamentals in EE or physics topics covered in coursework. 
  • Practical experience designing and building electronics hardware for a research project, competition team, extracurricular activity, prior internship, or advanced engineering course.
  • Hands-on experience with lab instruments such as oscilloscopes, spectrum analyzers, electronic loads, and signal generators.
  • Excellent written and verbal communication skills. CesiumAstro interns regularly present their work to peers, mentors, and executive leadership throughout the course of the summer. 


    • PREFERRED EXPERIENCE
  • Graduate coursework officially focused on Space Mission Design 
  • Familiarity with Basilisk Framework, GMAT, or STK for mission simulation 
  • Programming ability in C++ 
  • A minor or coursework in finance or business accompanying an undergraduate engineering or physics degree 
  • Advanced coursework space mission design, satellite business models, or related areas 


    • PREFERRED EXPERIENCE
  • Aerospace experience, such as a previous internship or school CubeSat project.
  • Familiarity with electronics schematic and layout tools such as Altium.
  • Familiarity with radiation engineering software such as ray tracing (FASTRAD), environment definition (OMERE, AE/AP9, CRÈME, SPENVIS), or particle transport.
  • Advanced coursework or research experience in semiconductors or circuit design.
  • Strong programming skills to support (C/C++, Python, MATLAB, etc.).
  • Experience with SPICE-based circuit simulation. 


    • All CesiumAstro internships are compensated competitively and located onsite at one of our facilities.
