About the role

How We Operate: Albedo takes a first-principles approach - in space and in business.
We move with speed, take calculated risks, and learn quickly.
We work in-person at our Broomfield CO HQ to maximize team and company productivity.

Design and implement a high-accuracy, real-time onboard orbit estimator for a VLEO spacecraft using EKF or equivalent nonlinear filtering approaches
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.
Design and validate short-term orbit prediction methods (propagation, smoothing, covariance growth characterization) and quantify prediction error during high-drag and geomagnetic storm conditions.
Support low-thrust operations by:
Contributing to steering law and guidance design in close coordination with GNC.
Generate and own robust, testable C/C++ flight software for real-time orbit determination, with strong attention to numerical stability, covariance integrity, and diagnosability.
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.
Provide technical support for GNSS spaceflight hardware integration, including measurement modeling, command and telemetry integration, calibration analysis, and anomaly triage.

In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.
Applicants must be a U.S. Person as defined under 22 CFR 120.62

Bachelor's or Master's degree in Aerospace, Electrical, Mechanical Engineering, Physics, or related field.
Proficiency in Python for analysis, simulation, and test automation.
Deep understanding of GNSS measurement modeling (code and carrier phase), bias handling, and real-world sensor pathologies.
Experience with covariance propagation, filter consistency testing (NEES/NIS), and operational health monitoring.
Experience with control theory and guidance for low-thrust or drag-modulated flight is a plus.
Experience designing regression tests, Monte Carlo campaigns, and closed-loop simulation environments.
Comfort leveraging modern AI-assisted development tools with strong verification discipline and traceability.

Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Albedo, we'd rather hear from you. We care more about how you think than which boxes you check. We value people who do the math, make their assumptions explicit, and ask the annoying questions: what breaks, what's the failure mode, what has to be true for this to work? If that sounds like you, apply, even if you don't meet every line.
