R&D Prototyping Engineer

Citra Space Corporation
Colorado, CO Full Time
POSTED ON 4/15/2026
AVAILABLE BEFORE 10/11/2026

In this role, you will support a broad range of engineering activities essential to our space domain awareness mission. This position requires a “jack of all trades” with a strong foundation in physics or engineering principles and practical skills spanning mechanical and electrical assembly, fabrication, programming, and 3D modeling. This is a hands-on role. You will also be a key contributor in operating and maintaining light manufacturing equipment (CNC mills/routers, laser cutters, and 3D printers) to build ruggedized enclosures, RF antennas, and mobile field kits. The successful candidate will collaborate across teams to execute tasks that range from hands-on fixture assembly to software scripting projects, contributing directly to the design, build, and deployment of advanced space object identification technologies in a fast-paced startup environment.


Responsibilities

  • Support mechanical and electrical assembly tasks including fixture and prototype fabrication
  • Operate, maintain, and improve light manufacturing equipment including CNC mills/routers, laser cutters/engravers, and 3D printers for small‑batch production and prototyping
  • Assist with field deployment and maintenance of telescopes, antennas, and related instrumentation
  • Develop and maintain 3D models and fabrication drawings for machined, laser‑cut, and printed parts using modern CAD tools
  • Write and debug Python scripts or other programming languages for automation, data processing, and basic test/fixture control
  • Create and execute basic CAM workflows (toolpath generation, post‑processing, and job setup) for CNC machining and PCB/antenna milling
  • Collaborate with engineers on diverse projects, adapting to daily shifting priorities and technical challenges
  • Participate in testing, troubleshooting, and documentation of hardware and software systems
  • Support shop setup, tool selection, and maintenance of parts and supplies


Qualifications

  • Education: Bachelor's degree in Physics, Mechanical Engineering, or related STEM discipline
  • Experience: 4–7 years of professional experience in a technical or engineering support role (prototype lab, R&D shop, light manufacturing, or similar)
  • Strong hands-on skills in mechanical assembly, light fabrication, and electrical systems
  • Proficiency with 3D modeling software and experience with 3D printing technology
  • Some programming skills, preferably in Python but experience with other languages is a plus
  • Ability to work independently and collaboratively in a dynamic, fast-paced environment
  • Excellent problem-solving skills and adaptability to changing project requirements
  • Familiarity with RF test equipment (spectrum analyzers, signal generators, VNAs) and RF testing procedures is a plus


This position requires compliance with U.S. export control laws and regulations. Applicants must be U.S. citizens or lawful permanent residents as defined by 8 U.S.C. 1324b(a)(3) to meet the requirements of the International Traffic in Arms Regulations (ITAR) and/or Export Administration Regulations (EAR).
