About NewOrbit Space

NewOrbit Space is a pioneering space technology company that is revolutionizing satellite operations in ultra-low Earth orbits. We are seeking a highly skilled and motivated Satellite Systems Engineer to join our team and contribute to the development and launch of groundbreaking technology.

Job Summary

The successful candidate will be responsible for leading the design, implementation, testing, and operation of Attitude Control Systems (ACS) for our satellites. This will involve working closely with a multidisciplinary team to ensure the accurate and reliable control of our spacecraft's orientation and trajectory.

Key Responsibilities
  • System Architecture and Design: Develop and evolve the spacecraft ACS architecture, including the design and integration of sensors, actuators, reaction wheels, magnetoquers, and control algorithms to achieve mission requirements.
  • Algorithm Development: Design and implement advanced ACS algorithms to support various pointing modes and attitude control scenarios, ensuring precise control over satellite orientation and stability.
  • Simulation and Modeling: Perform detailed sensor and actuator characterization, modeling, and simulation to predict system performance and optimize the design. Develop and utilize satellite simulators for system validation.
  • Hardware Integration: Specify, evaluate, and select ACS components, including reaction wheels, magnetorquers, star trackers, IMUs, and sun sensors. Integrate these components into the spacecraft, ensuring seamless interaction with other subsystems.
  • Testing and Validation: Develop and execute hardware-in-the-loop (HIL) tests, ground-based simulations, and in-orbit commissioning to validate ACS performance. Troubleshoot and resolve issues during the integration and testing phases.
  • On-Orbit Operations: Support on-orbit guidance, navigation, and control (GNC) system calibration, commissioning, and operations, including maneuver planning and fault management.
  • Documentation and Reporting: Produce and maintain detailed documentation for ACS design, development, testing, and operations. Communicate technical information effectively to internal teams and stakeholders.
Fundamental Requirements
  • Education: Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, or a related field. A Master's degree is preferred.
  • Industry Experience: Minimum of 2-5 years of experience in spacecraft attitude determination and control, with hands-on experience in the development, testing, and operation of ACS systems.
  • Technical Expertise: Strong knowledge of ACS components and systems, including sensors (IMUs, magnetometers, star trackers) and actuators (reaction wheels, magnetorquers). Experience with GNC systems is a significant plus.
  • Programming Skills: Proficiency in C/C++ for embedded systems development, with experience in Python and MATLAB for simulation and data processing. Familiarity with version control systems such as Git.
  • System-Level Understanding: Solid understanding of closed-loop control systems, orbital mechanics, and spacecraft dynamics. Ability to conduct detailed trade-off analyses to optimize ACS design.
  • Simulation and Testing: Experience with hardware-in-the-loop testing, satellite simulation, and ACS algorithm validation. Ability to design and execute comprehensive test plans.
Additional Requirements
  • Collaboration: Strong teamwork and communication skills, with the ability to work effectively in a multidisciplinary environment and collaborate with engineers across various domains.
  • Innovation and Problem-Solving: A creative and analytical mindset, with the ability to solve complex technical challenges and propose innovative solutions.
  • Adaptability: Ability to thrive in a fast-paced, dynamic environment, managing multiple tasks and priorities with a proactive approach.
Why NewOrbit Space
  • Pioneering Space Technology: Join NewOrbit Space and contribute to the development and launch of groundbreaking technology that will redefine satellite operations in ultra-low Earth orbits.
  • Impact and Ownership: Experience a rare level of involvement in the full lifecycle of satellite technology development, with opportunities to influence mission-critical systems.
  • Equity and Competitive Salary: NewOrbit Space offers competitive salaries and company ownership stakes, rewarding dedication and hard work with a tangible stake in the company's success.
