The journey to space starts with the engines. 

Ursa Major was founded to bring a new model to space access: one in which every link in an enormous value chain isn’t limited by those around it. We design rocket engines and propulsion solutions.  
Our products and technologies require an extraordinary team. A team that will mold tomorrow’s technologies while deploying today’s best. We are an intrinsically motivated team that has a passion for solving problems and empowering each other every day to develop our skills, knowing that there is always room for growth.

Our propulsion systems cannot function without sensors, actuators, controllers, and other electronic hardware functioning well together. You will work with our Design and Development teams to design avionics systems that meet the requirements of our systems and customers. In this senior role, you will be responsible for developing avionics hardware to interface measurement and control components to control software. The hardware will interface with measurement devices and actuators such as valves, pressure sensors, temperature sensors, accelerometers, BLDC motors, and communication buses. Having a solid foundation in electronics for harsh environments and a desire to build avionics for space applications is a must. You will help us define and implement our verification strategy using best practices and customer inputs.


  • Develop mixed-signal designs and shepherd them through the full product life-cycle; including requirements definition, design, development, qualification, and release to production.
  • Support avionics architecture trade studies, analyses, performance characterization and specification, device selection, and roadmap direction.
  • Perform de-rating analysis, worst-case circuit analysis, FMECA, and system reliability analysis.
  • Develop avionics systems that interface with sensors and actuators.
  • Support definition and implementation of hardware to software interfaces to implement control law and automated test functions.
  • Support risk analyses, design for test/manufacture/cost, and root-cause analysis of test discrepancies.
  • Participate in program-level technology development, mission and safety objectives, and avionics development process improvements.
  • Support rocket engine testing and ground support as necessary


  • Demonstrated experience in delivering flight avionics for aircraft, launch vehicles, or other space applications.
  • B.S. in Electrical or Computer Engineering or related field with 5+ years of direct experience in electronics hardware development.
  • Understanding of analog/digital filtering, mixed-signal circuit design, analysis, and test design.
  • Knowledge of signal integrity, power, grounding, and general board layout principles.
  • Understanding of sensor and actuator technologies including: RTD’s, Pressure Transducers, DC brushless motors, Solenoid valves, Thermocouples, Hydraulic servo valves, LVDT, RVDT, Rotary/Linear Encoders.
  • Working knowledge of EMI/EMC practices and; MIL-461, DO-160, or FCC compliance.

Desired Experience

  • Direct experience in launch vehicle avionics systems integration
  • Graduate degree in related engineering or technical field with 15+ years of direct experience in electronics hardware development
  • Demonstrated expertise in designing Class 3 board assemblies
  • Utilizing IPC 6xx and NASA-STD-8739.n (or similar) standards.
  • Proficiency in using KiCad (or similar tools) to design complex boards; experience working with external board manufacturing and assembly vendors.
  • A desire to design mission-critical hardware for flight applications.
  • Working knowledge of high-reliability, radiation-tolerant, and radiation-hardened flight hardware intended for high altitude and space environments.
  • Proficiency with scripting; programming and analysis/modeling tools: Python, Linux/Windows shell scripting; assembly language, C, C++; MATLAB / Simulink / SPICE (or similar)
  • Exposure to designing safety or mission-critical aerospace flight hardware compliant with DO-254.

Benefits Include:

  • Unlimited PTO - Vacation, Sick, Personal, and Bereavement
  • Paid maternity/paternity/adoptive leave
  • Medical, Dental and Vision Insurance; Tax Advantage Accounts (HSA/FSA); Employer Paid Short and Long Term Disability, Basic Life, AD&D and EAP Program; Additional Benefit Options Including Voluntary Life, Emergency Medical Transport and Pet Insurance
  • Retirement Savings Plan - Traditional 401(k) and a Roth 401(k)
  • Company stock options
