Why Join Us? Dynamic Work Environment: Engage in a vibrant, international setting with numerous collaboration partners, primarily in Europe. Comprehensive Skill Development: Enhance your expertise in various technical domains, from Mechanical design to System engineering. Team Collaboration: Work closely with system, electrical, thermal, and AIT engineers in the development of cutting-edge satellites. Project orientation: Take lead on discussions with customers and suppliers, managing relations in- and outside of OHB Sweden. What We’re Looking For: A structured, motivated, mechanical analysis engineer with proven leadership abilities. Ability to work independently while meeting agreed delivery schedules. Strong collaboration skills to work effectively with diverse teams. Ability to plan and drive the success of our projects. Task Description: Having a lead role on mechanical, structural, and dynamic components using FEM, focusing on stress, shock, and random vibration analyses. Lead technical discussions with customers and suppliers. Supervise off-site testing of parts and inspect delivered items. Support on-site assembly of end products, such as spacecraft structures. Define and design test specifications, procedures, and setups for subsystem qualification (structures, mechanisms, units, components, actuators). Correlate FE models (e.g., fundamental frequencies, damping coefficients) with actual test results. Assist in planning and budgeting for future programs and projects. Design, assemble, and test mechanical ground support equipment (MGSE) for integration and test activities. Mentor junior engineers and provide technical guidance within the team. Required Qualifications: Bachelor’s or Master’s Degree in Mechanical Engineering, Space Engineering, or related disciplines. Minimum of 10 years of experience in design and testing environments related to CAD, mechanical FEM analysis, and design. Proven ability to lead and inspire teams and/or groups, driving projects forward. Experience within ESA projects. Good knowledge of the ECSS. Expertise with NASTRAN,Altair, Hypermesh, Optistruct Proficiency in FEM analysis, particularly in random vibration response, shock, and loads analysis. Ability to generate, read, and understand mechanical design/analysis reports and Interface Control Documents (ICDs). Clear and coherent reporting and presentation skills in English. Experience in design-to-manufacture processes. Fluent in English, both spoken and written. Located in or willing to relocate to Stockholm, Sweden. Added Advantageous Qualifications: Experience in writing test procedures for vibration and shock. Experience in requirements management and verification. Experience with CREO and/or NX (CAD) and Windchill PLM. Experience working closely with production/MAIT. Experience in GPS (Geometric Product Specifications) drawing production.
