Lead the design and development of complex mechanical systems from requirements definition to validated hardware, ensuring an optimal balance between performance, manufacturability, cost, and reliability. As a technical reference within the team, you will drive engineering decisions, collaborate across disciplines, review designs, and contribute to the successful delivery of high-performance products for challenging aerospace and space applications. Senior mechanical design engineer with 5+ years of hands-on experience. Strong expertise in advanced 3D CAD modelling, most preferably SolidWorks. Experience with Siemens NX, CATIA, Creo or equivalent CAD platforms is also valued. Demonstrated experience translating external and internal requirements into robust mechanical solutions, balancing performance, manufacturability, cost, schedule and integration constraints throughout iterative development cycles. Extensive experience designing complex mechanical components and assemblies, with a strong understanding of mechanical interfaces, system integration and configuration control. Proven ability to analyse engineering challenges critically, generate alternative design approaches, evaluate trade-offs and drive technical decisions based on engineering evidence. Strong experience creating detailed manufacturing documentation, including GD&T, interface definitions, assembly procedures and technical drawing packages. Good knowledge of manufacturing processes and Design for Manufacturing/Assembly (DFM/DFA), particularly machining, metal fabrication, additive manufacturing and precision assembly. Experience collaborating closely with multidisciplinary teams, including mechanical, thermal, systems, manufacturing and test engineers, to converge on optimal technical solutions. Practical understanding of mechanical and thermal analysis workflows, including model preparation, meshing strategies, simulation setup, interpretation of results and validation of engineering assumptions. Direct hands-on FEA/thermal simulation experience is highly desirable. Experience managing CAD structures, revisions, configurations, technical baselines and documentation within a PDM/PLM environment. Strong experience working in collaborative design environments, coordinating parallel development activities and maintaining consistency across multiple subsystems and contributors. Detail-oriented, proactive and solution-driven, with excellent communication skills and the ability to constructively challenge assumptions when required. Motivated to work in a fast-paced and ambitious engineering environment, taking ownership of technical challenges and continuously improving both products and engineering practices. Nice to Have Previous experience in the space industry is strongly preferred. Experience working on spacecraft, propulsion systems, scientific instruments, aerospace hardware or other highly demanding engineering products.
