This is a critical capability that enables autonomous electromagnetic docking. You will own the vision system that detects and tracks neighboring tiles. You will develop sensor fusion solutions that allow the docking controller to remain robust through the capture envelope, from first acquisition to contact. You will carry the development from prototypes to flight: define the sensor-suite and interface requirements, build calibration, simulation, and test infrastructure, implement and verify algorithms on the ground and in orbit, define metrics and dashboards to track system performance, and resolve on-orbit anomalies. You will work alongside a small team of GNC, flight software, and avionics engineers to build capabilities for next-generation self-assembling satellites. If you are energized by solving hard problems, then this role is for you. Responsibilities • Own relative navigation for proximity operations and docking end to end: perception, sensor fusion, and the estimator that feeds the control loop, • Take the tile vision system to flight: detection, calibration, pose estimation, outlier rejection, and robust performance across range, environment, and relative motion, • Design, implement, tune, and verify the relative-state estimator (EKF, MEKF, UKF, etc) that fuses vision with the other relative sensors, including the handoff between sensors as range closes, • Derive measurement models from first principles for each sensor in the relative-navigation suite, • Define and own the navigation accuracy budget as a function of range and the sensor-suite and interface requirements (rate, latency, covariance, dropout) that meet it, • Build the calibration and ground-truth infrastructure that lets perception performance be measured on the bench and carried into simulation, • Verify performance and robustness with hardware-in-the-loop experiments, using statistical consistency tests, • Implement perception and navigation algorithms in onboard flight software in C++ and develop the supporting simulations, tools, and dashboards in Python, • Support flight operations, monitor on-orbit navigation health, and lead on-orbit anomaly investigationsBasic Qualifications, • Bachelor's degree in aerospace/electrical engineering, physics, mathematics, computer science, or other relevant engineering discipline, • Software development experience in C++ and Python, • Hands-on experience delivering camera-based pose estimation or multi-sensor fusion on a real robotic or space systemPreferred Qualifications, • Master's or PhD in robotics, computer vision, or an engineering discipline, or 5+ years of professional perception, state-estimation, or GNC experience, • Expertise in computer vision for metric pose: camera models and calibration, fiducial or feature-based pose estimation, multi-view geometry, and image processing on embedded compute, • Expertise in sequential estimation: Kalman filtering, residual editing, filter tuning, covariance analysis and realism, consider parameters, and consistency testing (NIS/NEES, chi-squared), • Experience fusing asynchronous, latent, dropout-prone measurements from heterogeneous sensors, including time synchronization and attitude representation on SO(3), • Proficiency in sensor handling: measurement modeling, debiasing, calibration, and characterization on the bench, • Familiarity with embedded software development and real-time constraints, • Understanding of electromagnetic systems, orbital mechanics, and proximity-operations dynamics is a plus, • Proven ability to develop, test, and deploy algorithms for real-world space or robotic applications, with proficiency in Git, • Capable of identifying and solving complex problems with little to no supervision in a fast-paced start-up environment, • Passionate about solving hard problems, building things, and advancing the space industry, • Excellent written and verbal communication skillsCompensation and Benefits Base salary range: $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.

Xcimer’s central goal is commercial fusion, and this role carries technology in both directions. Beam control lessons from the Directed Energy program feed directly into our fusion beamlines, where the same deep-UV wavefront and pointing problems reappear at a different scale and duty cycle. You will help set the beam control direction for fusion on the strength of what you deliver on Directed Energy. Additionally, we are building the adaptive optics group. You will help set the technical standards and development practices it works to, mentor the engineers and scientists in it, and take on technology development that outlives any single program. We move on real hardware quickly. We want the governing equations and a first-order layout before money is committed, and we want a cheap experiment that could break the concept shortly after. We are looking for our scientists and engineers to apply their technical expertise, problem solving skills, and dedication to quality to positively impact the future of energy and national security!

Vendor and Partner Engagement • Act as a primary technical interface to our external program partners on adaptive optics and beam control. Negotiate interfaces and requirements, participate in joint design reviews, and carry a substantive share of a joint development effort., • Own the technical side of adaptive optics procurements and development subcontracts: statements of work, specification negotiation, vendor technical reviews, and acceptance criteria and testing., • Plan and defend the resources the adaptive optics scope needs: scope, schedule, staffing, and build-versus-buy calls, including where a commercial system suffices and where development is unavoidable., • Act as the primary technical interface for resolving performance, schedule, and integration issues with suppliers., • Communicate complex beam control trades clearly to audiences ranging from partner engineers to program leadership. Integration, Test, and Commissioning • Define the proof-of-concept and risk-reduction experiments that settle open questions, then direct optical engineers, laser scientists, and technicians to run them and interpret the results., • Define and review laboratory and in-situ test plans that validate performance and closed-loop operation, and approve the resulting test reports., • Provide guidance and best practices to other engineers in the assembly, integration, and test of beam control hardware within the beamline environment, including contamination-control discipline appropriate to deep-UV, high-fluence optics., • Work with control system engineers to integrate adaptive optics within the larger laser control system, helping define required controls, interlocks, and operator feedback., • Support commissioning activities and the transition to reliable, repeatable operations, including field or range testing where required.

Job Description Today, everything we send to space has to fit inside a rocket fairing, a dimensional limit that has not changed even as the rest of the industry has. That's a fundamental bottleneck to building more capable spacecraft. Rendezvous Robotics is solving this with electromagnetic self-assembling tiles, modular spacecraft components that maneuver and assemble in orbit into spacecraft more capable than anything built on Earth and folded into a rocket. Once assembled, those spacecraft can be expanded, reconfigured, or repaired on orbit rather than replaced. We're a small team based in Golden, Colorado, executing on a clear path from flight demonstration to our first operational systems.
