We are seeking a Sr. Mechanical Designer to join Xona’s spacecraft hardware development team in Montréal, at the historic RCA Victor Building in St. Henri. In this role, you will support the design, development, and testing of mechanical systems such as those that enable spacecraft attitude determination and control and improve power performance.
You will work closely with controls, electrical, systems, avionics, and software engineers to help develop high-reliability electromechanical hardware for satellite flight systems. This is a hands-on role involving both electrical design and laboratory testing, with opportunities to contribute throughout the development lifecycle from early prototyping, through spacecraft integration and test and into full scale manufacturing.
What You’ll Do
Own subsystem design authority for assigned hardware, including requirements decomposition from spacecraft-level specs.
Support the design and development of mechanical subsystems for spacecraft system hardware, with a focus on dynamic mechanical systems and assemblies (ie rotors, bearing design and housing.
Collaborate with mechatronics engineers on integrated rotor/bearing/housing designs, ensuring mechanical and thermal interfaces meet objectives.
lead mechanical and thermal design of components, including active components and housings.
Assist with development and execution of test plans for prototypes, engineering model, and flight hardware.
Troubleshoot and debug mechanical assemblies in the lab and develop a detailed test plan for execution (activities such as balancing).
Support integration of hardware with spacecraft considering the transferred environments.
Support Design for Manufacturability (DFM) efforts as subsystems transition from prototype to sustained production, including fixture development.
Assist with hardware bring-up, verification testing, and environmental test campaigns.
Support supplier component evaluation and selection for mechanical and thermal components.
Required Qualifications
Bachelor’s degree in mechanical engineering or a related field.
Experience in leading mechanical (dynamic system) hardware design and development from concept to MVP and beyond.
Familiarity and mechanical CAD (such as solidworks) and finite element modelling and analysis tools for structural, thermal, and dynamic analysis.
Demonstrated experience designing electric motor drives, engine assemblies, or systems for precision mechanisms and robotics.
Strong understanding of kinematics and dynamics, including the ability to specify, model, design, and test to those bound.
Solid fundamentals in machine design, mechanics of materials, and thermodynamics.
Hands-on experience with mechanical testing equipment (vibration, thermal cycling, etc).
Strong problem-solving ability and attention to detail.
Ability to work collaboratively within multidisciplinary engineering teams.
Desired Qualifications
Experience with precision robotics.
Experience with electric motors and high-speed rotary assemblies.
Exposure to spacecraft systems, ADCS hardware, or electromechanical control systems.
Experience supporting hardware integration, assembly, or environmental testing.
Understanding of control systems and application of control theory.

Contribuer à la conception et au développement de sous-systèmes mécaniques pour le matériel spatial, avec un accent sur les systèmes mécaniques dynamiques et les assemblages (p. ex. rotors, paliers et boîtiers).
Collaborer avec les ingénieur·e·s en mécatronique sur la conception intégrée rotor/paliers/boîtiers, en s’assurant que les interfaces mécaniques et thermiques respectent les exigences.
Diriger la conception mécanique et thermique de composants, incluant les composants actifs et leurs boîtiers.
Contribuer à l’élaboration et à l’exécution de plans d’essais pour des prototypes, des modèles d’ingénierie et du matériel de vol.
Diagnostiquer et résoudre des problématiques sur des assemblages mécaniques en laboratoire et élaborer des plans d’essais détaillés (p. ex. équilibrage).
Soutenir l’intégration du matériel au satellite en tenant compte des environnements transmis.
Contribuer aux efforts de conception pour la fabricabilité (DFM) lors de la transition des prototypes vers la production soutenue, incluant le développement d’outillages.
Participer à la mise en service du matériel, aux essais de vérification et aux campagnes d’essais environnementaux.
Appuyer l’évaluation et la sélection de composants auprès des fournisseurs (mécaniques et thermiques).
Qualifications requises
Baccalauréat en génie mécanique ou dans un domaine connexe.
Expérience en conception et développement de matériel mécanique (systèmes dynamiques), de la phase conceptuelle jusqu’au produit minimal viable (MVP) et au-delà.
Maîtrise des outils de CAO mécanique (p. ex. SolidWorks) ainsi que des outils de modélisation et d’analyse par éléments finis pour les analyses structurelles, thermiques et dynamiques.
Expérience démontrée en conception de moteurs électriques, d’assemblages mécaniques ou de systèmes pour mécanismes de précision et robotique.
Solide compréhension de la cinématique et de la dynamique, incluant la capacité de spécifier, modéliser, concevoir et tester selon ces paramètres.
Bonnes bases en conception de machines, en mécanique des matériaux et en thermodynamique.
Expérience pratique avec des équipements d’essais mécaniques (vibration, cycles thermiques, etc.).
Excellentes aptitudes en résolution de problèmes et souci du détail.
Capacité à collaborer efficacement au sein d’équipes multidisciplinaires.
Qualifications souhaitées
Expérience en robotique de précision.
Expérience avec les moteurs électriques et les assemblages rotatifs à haute vitesse.
