Jobs at Xona Space Systems

The Sr. Mechatronics Designer will design and test electromechanical systems for spacecraft, collaborating with various engineering disciplines to ensure reliability and performance.

Develop, validate, and maintain high-fidelity six-degree-of-freedom spacecraft digital twins and flexible-body models. Build physics-based models for dynamics, sensors, actuators, and disturbances; apply system identification, derive linear approximations, and support control design, Monte Carlo analysis, and HIL/SIL testing through model-based development and verification.

Manage cap table and equity administration in Carta, maintain corporate governance and legal records, support entity formation and compliance across jurisdictions, assist with venture financings and investor due diligence, manage contract workflows and legal document repositories, and improve legal operations while partnering with Finance, HR, Tax, and external counsel.

As a DevOps Engineer, you'll develop and maintain CI/CD pipelines, automate testing, manage infrastructure, and improve build processes for high-quality software releases.

As a Junior Software Developer, you will design and execute software test procedures for satellite systems, implement automated testing frameworks, and validate hardware interactions.

The Build & Release Software Engineer will design and optimize build systems, manage CI/CD workflows, and improve software development processes for satellite systems using C++ in embedded Linux environments.

The Mechanical Engineer will design and manage RF systems hardware, ensuring project delivery from design to testing within a collaborative team.

Lead development and architecture of navigation subsystems (precise positioning, orbit determination, clock estimation, atmospheric modeling, integrity monitoring), mentor engineers, and translate algorithms into flight-ready software and interfaces with payload and systems engineering.

Design and implement high-performance signal-processing solutions for LEO PNT satellite systems, focusing on FPGA optimization, DSP algorithms, and hardware integration.

Design, develop, and integrate electrical subsystems and PCBAs for satellite payloads. Own schematic-to-layout workflows, perform lab bring-up, troubleshooting, and system-level integration and testing. Capture requirements, run trade studies, document interfaces, and mentor teammates while improving design practices and reliability methods for space hardware.

Design, build, and qualify spacecraft fluid and pressurized gas systems end-to-end: component selection, CAD/BOM ownership, test infrastructure, automation for ground tests, DOT compliance, and integration with satellite bus.

Lead architecture and detailed design of high-voltage power electronics for satellite propulsion from concept through flight qualification. Responsibilities include DC-DC converter and control electronics design, component selection/qualification, analysis for electrical/thermal/radiation environments, prototyping, test plan development, troubleshooting, spacecraft integration, and supporting manufacturability and production.

Own full-cycle recruiting for high-priority technical roles while mentoring a team of recruiters. Source, engage, and close candidates; partner with executives and hiring managers; enforce consistent interview processes, evaluation standards, and high-quality candidate communication.

Lead planning and execution of Montreal-based spacecraft subsystem development and manufacturing. Maintain schedules, track risks and dependencies, coordinate across US and Montreal teams, manage suppliers, produce program reporting, and develop lightweight PM processes for a small, fast-moving hardware team.

Design and implement algorithms for orbit controls including orbit determination, station-keeping, maneuver execution, and analysis to ensure spacecraft efficiency and safety.

Develop production-grade software for a satellite communication system, focusing on cybersecurity and cryptography. Implement cryptographic modules, defensive programming techniques, and lead ground software development.

The Site Reliability Engineer will architect and manage ground infrastructure for satellite systems, ensuring high availability, automating deployments, and optimizing data management systems.

The role involves designing and developing mechanical systems for spacecraft, collaborating with cross-disciplinary teams, and conducting testing and integration.

The Sr. Flight Dynamics Engineer will design and analyze satellite constellation architecture, perform orbital analysis, and develop collision avoidance strategies for LEO missions.

The Regulatory & Policy Manager will lead engagements with government and regulatory bodies, shaping the company's regulatory strategy while ensuring compliance with international laws governing commercial space activities.
