Senior GNC Engineer, Navigation (Swarm/Vehicle)

Golden, Colorado

Today, everything we send to space is constrained by what fits inside a rocket fairing. That's a fundamental bottleneck to building more capable spacecraft. Rendezvous Robotics is solving this problem with electromagnetic self-assembling tiles: modular spacecraft components that rendezvous, dock, and latch to assemble bigger and more powerful spacecraft than anything that can be folded to fit into a rocket.

We're a small team based in Golden, Colorado, executing on a clear path from flight demonstration to our first operational systems. Our work spans hardware, software, and systems engineering. We are looking for the best people in the world who want to build the next generation of advanced spacecraft.

Senior GNC Engineer, Navigation (Swarm/Vehicle)

As a Senior GNC Engineer, Navigation (Swarm/Vehicle), you will be responsible for the complete lifecycle of the relative-state estimation that makes electromagnetic docking possible. You will define the navigation accuracy budget the control loop is built on, design and tune the filter that delivers relative ranging and bearing from the tile sensor suite, prove it through analysis and simulation, and bring it into reality in onboard flight software. This is an opportunity to apply expertise in estimation and sensor fusion to both set the sensor suite and interface requirements and implement the onboard navigation that delivers them —working collaboratively across control, perception, and avionics to close the docking loop on hardware, ultimately defining the navigation scope and requirements for future tiles. Secondarily, you will also support absolute navigation of the swarm once it is docked, latched, and now functioning as a monolithic spacecraft/vehicle. These are the traditional set of GNC problems related to orbit navigation and propagation.

Responsibilities

  • Develop highly reliable, performant state estimation and navigation algorithms, simulations, tools, and dashboards in C++ and Python
  • Own relative-state estimation for proximity operations and docking: design, implement, tune, and verify filters (EKF, UKF, etc)
  • Deliver relative pose- and position-knowledge at the range-dependent requirements that guarantee closed-loop stability
  • Derive measurement models from first principles for relative ranging and bearing from the tile sensor suite
  • Define and own the perception interfaces to navigation
  • Verify estimator performance and robustness with hardware-in-the-loop (HITL) experiments
  • Support flight operations, monitor on-orbit health and performance, lead on-orbit anomaly investigations, and drive on-orbit system reliability of navigation algorithms
  • Secondarily, support development of navigation algorithms for the assembled spacecraft

Basic Qualifications

  • Bachelor's degree in aerospace/electrical engineering, physics, mathematics, or other relevant engineering discipline
  • Software development experience in C++ and Python

Preferred Qualifications

  • Master's or PhD in an engineering discipline or physics: 5+ years of professional GNC or state-estimation experience
  • Expertise in computer vision, sequential estimation techniques, including Kalman filtering, residual editing, filter tuning, covariance analysis, consider parameters, adaptive processes, and covariance realism
  • Strong understanding of electromagnetic systems, orbital mechanics and high-fidelity orbit propagation (perturbations in low-Earth orbit, drag modeling, etc), and embedded software development
  • Proficiency in measurement and sensor handling, including measurement processing, measurement modeling, debiasing, sensor calibration, image processing, optical observations, etc
  • Proficiency in data analysis techniques, including statistical tests (e.g., chi-squared, Kolmogorov-Smirnov) and data correlation methods
  • Proven ability to develop, test, and deploy algorithms for real-world space/robotic applications, with proficiency in version control systems like Git
  • Capable of identifying and solving complex problems with little to no supervision or direction in a fast-paced, start-up environment
  • Passionate about solving hard problems, building things, and advancing the space industry
  • Excellent written and verbal communication skills

Compensation and Benefits

Senior GNC Engineer: $145,000.00 - $190,000.00

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. In addition to the base salary, you may also be eligible for long-term incentives in the form of stock options. You will receive access to comprehensive medical, vision, and dental coverage, short- and long-term disability insurance, life insurance, and paid parental leave. You may also accrue 3 weeks of paid vacation and will be eligible for 10 or more paid holidays per year.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
