Valves are critical components in spacecraft propulsion systems, where high reliability, low mass, and efficient operation are essential. OHB Sweden is currently investigating a new valve concept for future space applications and is seeking a Master's student to support the early stages of the product development. The thesis will focus on establishing a preliminary product definition, identifying key requirements, evaluating design concepts, and performing first-order sizing and analysis of critical components and operating parameters. Depending on project progress and thesis scope, the work may also include the design, manufacturing, and testing of an initial prototype.

OHB Sweden is looking for a Master's student to support the early development of a new valve concept for spacecraft propulsion systems. During the thesis, you will work with the complete early-stage development process, from defining requirements and evaluating design concepts to preliminary sizing, modelling, and engineering design. The work will involve balancing key considerations such as performance, reliability, manufacturability, mass, and power consumption. Depending on the progress and final scope of the thesis, you may also have the opportunity to design, manufacture, and test a proof-of-concept prototype. You will carry out the thesis as part of OHB Sweden's propulsion team, working closely with experienced engineers and contributing to the development of technology intended for future space applications. THE TASKS OF THE MASTER'S THESIS TOPIC ARE AS FOLLOWS: The student will contribute to the early development of the valve through activities such as: * Identification and analysis of applicable requirements. * Functional analysis and product definition. * Evaluation of alternative concepts and design solutions. * Preliminary sizing and modelling of critical components and operating parameters. * Assessment of performance, reliability, manufacturability, mass, and power consumption. * Development of a preliminary engineering design. * Design, assembly, and testing of a proof-of-concept prototype, if time permits. THE REQUIRED CANDIDATE’S SKILLS ARE: The position is suitable for Master's students in: * Aerospace Engineering * Mechanical Engineering * Mechatronics * Electrical Engineering * Engineering Physics * Applied Physics * Or a related engineering discipline Experience with CAD, simulation, product development, testing, or modelling is considered beneficial but is not required. WHAT CAN WE OFFER THE STUDENT FOR THEM TO SUCCEED IN THEIR MASTER'S THESIS? The student will become part of OHB Sweden's propulsion team and contribute to the development of a new spacecraft propulsion technology. The work offers hands-on experience with real hardware development and close collaboration with engineers working on current and future space missions.

OHB Sweden is Sweden’s largest spacecraft system integrator, regularly producing AOCS and propulsion subsystems parallel to complete spacecraft in our cleanroom in Kista. For these systems, it is sometimes necessary to understand how components are placed and oriented relative to each other. To determine these relationships, different measurement techniques are used, with the discipline collectively called metrology. We are seeking a Master Thesis Student to investigate and implement new metrological methodologies that would aid the design and production of the next generation of spacecraft systems and subsystems. THESIS TASKS The thesis would focus on developing new metrological techniques based on the requirements of OHB Sweden. Tasks would include: * Assess the current state-of-the-art metrology in the space industry * Identify and explore emerging techniques * Identify potentials for improvements in the state-of-the-art and/or emerging techniques * Develop new technique(s) that implement such improvements based on the requirements of the company * Analyze the new technique(s) in parameters such as accuracy, repeatability, robustness, and execution speed * Suggest future paths for the company and the discipline at large * Summarize your findings in a thesis report * If opportunities for it arise: perform experimental validation or testing using the metrological tools at OHB Sweden The goal is to develop new metrological methods that increase the quality of the spacecraft and subsystems developed at the company while decreasing the required time for integration and testing. The student is also encouraged to suggest additional or alternative paths with the same goal. WHO WE ARE LOOKING FOR We are looking for someone that fulfills several of these items: * Final-year master’s students in the field of Aerospace Engineering, Applied Mathematics, Mechanical Engineering, Engineering Physics, and similar disciplines * Good understanding of the relevant mathematics, such as linear algebra and statistics * Experience with data analysis * An interest in analyzing measurement data and exploring practical engineering problems * An independent mode of operation in a goal and results-oriented manner * Experience with languages such as Python or MATLAB * Fluency in English It is considered meriting to have experience with: * Knowledge of measurement science, sensor systems, computer vision, photogrammetry, robotics, or similar areas * AOCS, propulsion systems, spacecraft systems or optical systems * Measurement systems, testing setups, and testing activities * Experience within the space sector * Automation We would like you to be curious, passionate, driven, and open to learning and trying new things. We welcome applicants of any gender interested in spacecraft engineering to apply! WHAT WE OFFER The student would be supported by experienced space systems engineers throughout the project and would gain exposure to current development activities. Additionally, during the thesis supervised access to laser metrological instruments could be provided for testing novel techniques developed by the student. Successful thesis work may also open a path towards future employment within the systems engineering or testing teams at OHB Sweden.

As an Mechanical, Thermal & Propulsion (MTP) Systems Engineer, you will play a key role in shaping the next generation of spacecraft propulsion systems at OHB Sweden. Our customers include major space companies, agencies, and commercial operators across Europe and worldwide. OHB Sweden develops propulsion systems for a wide range of scientific, commercial, and Earth-observation missions. Our propulsion solutions enable orbit raising, station keeping, attitude control, collision avoidance, and end-of-life disposal for spacecraft operating in increasingly demanding mission environments. The Propulsion Department is responsible for the complete lifecycle of OHB Sweden's propulsion products, including system design, analysis, testing, qualification, production support, and future technology development. The department plays a central role in enabling mission success and is a key contributor to OHB Sweden's long-term competitiveness in the rapidly evolving space industry. As our propulsion business continues to grow, we are strengthening our engineering organization with a new multidisciplinary technical leadership role.
