GNSS Navigation and Estimation Engineer

<div class="content-intro"><h2><strong>Be one of the Bedo 100</strong></h2> <div>Albedo is making Very Low Earth Orbit (VLEO) mainstream, building the infrastructure to usher every satellite mission set into this new orbital domain. We build buses, integrated satellites, and turnkey missions for customers to thrive in VLEO, between 250 km - 400 km, where proximity compounds performance and drag self-cleans debris.</div> <div> </div> <div>As part of the first 100 employees at Albedo, you will have a big impact on Albedo’s trajectory to proliferating VLEO — whether you’re advancing hardware to increase satellite longevity, scaling production for large constellations, building next-gen flight and ground software to push performance, or enabling missions that matter for national security and our day-to-day life here on earth.</div> <div> </div> <div><strong>How We Operate:</strong> Albedo takes a first-principles approach — in space and in business. We move with speed, take calculated risks, and learn quickly. We use AI regularly to create leverage in every discipline across the company. We work in-person at our Broomfield CO HQ to maximize team and company productivity. We work hard and with urgency to compound our first-mover advantage.</div> <div> </div> <div><strong>Who We're Looking For:</strong> Builders who want to own outcomes, not tasks. Systems thinkers who balance precision with iteration while thinking about the big picture. Individuals who are energized by creating a category rather than competing in an existing one. You’ll join a team that has already proven what others said wasn’t feasible and is now scaling and upgrading our VLEO buses payloads to serve mission sets across sensing, communications, and responsive operations.</div> <div> </div> <div>If you can feel the excitement running through your veins, apply to be one of the Bedo 100.</div></div><h3 class="p-rich_text_section">What You’ll Do:</h3> <ul class="p-rich_text_list p-rich_text_list__bullet p-rich_text_list--nested" data-stringify-type="unordered-list" data-list-tree="true" data-indent="0" data-border="0"> <li>Design and implement a high-accuracy, real-time onboard orbit estimator for a VLEO spacecraft using EKF or equivalent nonlinear filtering approaches; incorporate dynamic force modeling (gravity, drag, SRP), atmospheric drag state estimation, and reprocessing of raw GNSS measurements (code and carrier phase where applicable).</li> <li>Develop and maintain the dynamic process models used in both real-time filtering and short-horizon prediction, including uncertainty propagation and covariance realism analysis suitable for maneuver planning and conjunction inputs.</li> <li>Design and validate short-term orbit prediction methods (propagation, smoothing, covariance growth characterization) and quantify prediction error during high-drag and geomagnetic storm conditions.<br>Support low-thrust operations by: <ul> <li>Modeling finite-burn dynamics within the estimator,</li> <li>Performing maneuver reconstruction and thrust parameter estimation,</li> <li>Contributing to steering law and guidance design in close coordination with GNC.</li> </ul> </li> <li>Analyze orbit–attitude–drag coupling in VLEO and incorporate those effects into estimation and prediction models.</li> <li>Generate and own robust, testable C/C++ flight software for real-time orbit determination, with strong attention to numerical stability, covariance integrity, and diagnosability.</li> <li>Build and maintain ground-based validation and regression infrastructure, including closed-loop simulation, measurement replay, Monte Carlo campaigns, and hardware-in-the-loop testing with GNSS receivers and antenna systems.</li> <li>Provide technical support for GNSS spaceflight hardware integration, including measurement modeling, command and telemetry integration, calibration analysis, and anomaly triage.</li> </ul> <h3 class="p-rich_text_section">Your Ideal Skills and Experience:</h3> <ul> <li>Bach ...
