About the Job

Requirements

  • A bachelor's degree in a technical engineering discipline is required.
  • 0–3 years of experience working in guidance, navigation, and control is required.
  • Software development experience in Python is required.
  • Experience developing, debugging, and deploying guidance, navigation, and control sensors, effectors, and algorithms used in real-world applications or projects is required.
  • Ability to work in a fast-paced, autonomously driven, and demanding startup environment is required.
  • Proven ability to lead a project from conception to completion is required.
  • Must be willing to work extended hours and weekends as needed.

Responsibilities

  • Architect hardware and software solutions to accomplish space mission objectives involving space domain awareness and rendezvous, proximity operations, and docking, with an emphasis on autonomy.
  • Evaluate and select suitable mission techniques, including machine-learning methods, physics-informed solutions, stochastic methods, and Kalman filters.
  • Assist with proposal-capture efforts through feasibility analysis and engagement with private and public partners, the Department of Defense, other government agencies, and commercial partners.
  • Develop architecture and lead trade studies and the guidance, navigation, and control team from conceptualization through flight for rendezvous, proximity operations, and docking missions.
  • Design algorithms, simulations, and tools for orbit determination, state estimation, and uncertainty propagation to support space domain awareness efforts.
  • Analyze and source datasets for algorithm training and performance validation.
  • Build and test modeling and simulation tools for orbital and cislunar dynamics, sensor modeling, and visualization.
  • Model, simulate, and validate six-degree-of-freedom spacecraft dynamics, sensors, and algorithms, including for rendezvous, proximity operations, and docking missions.
  • Collaborate with software and guidance, navigation, and control teams to implement algorithms in flight software.
  • Support hardware-in-the-loop testing for integrated system validation.
  • Design spacecraft mission concepts of operations that balance thermal, power, momentum, and communications constraints.
  • Provide mission-operations training and support.

Desired Qualifications

  • Experience with cradle-to-grave spacecraft design, testing, verification and validation, and in-orbit mission operations.
  • Expertise in guidance, navigation, or control.
  • Experience with multi-body astrodynamics.
  • Experience with Git, Linux, and Basilisk.
  • Software development experience in C or C++.
  • Ability to identify and solve complex problems with little to no supervision or direction.
  • Strong written and verbal communication skills.

About the Company

Katalyst Space Technologies

Post-launch satellite upgrade services

Katalyst Space Technologies upgrades satellites after they are launched. It offers a post-launch upgrade service that adds or improves satellite capabilities without the need to launch a new spacecraft. The process centers on an “upgrade economy” where operators pay for modification and capability enhancements, often paired with life-extension work, to extend a satellite’s useful life and keep its features current amid rapid space changes. The company differentiates itself by focusing on post-launch adaptability rather than building new satellites, reducing waste and orbital congestion and enabling testing of new tech on existing platforms. Its clients are established space companies and government agencies seeking to unlock new revenue and access to markets without the high costs and risks of new launches. The goal is to provide a sustainable, cost-effective way for satellite operators to adapt to evolving space environments and maintain competitiveness.
