Job Description
The candidate will work on various small satellite missions within the company's Mechanical Design team. This area is responsible for all tasks related to the mechanical and structural design of satellites, including modeling, simulation, and analysis of components and structures using advanced design tools.

Throughout this process, the selected candidate will actively participate in key activities such as detailed design of satellite mechanical subsystems, development of optimized structures for launch and space environments, component integration, and the creation of 3D models and assemblies. Additionally, they will collaborate in design validation through finite element analysis and physical testing, ensuring compliance with technical and mission requirements. They will also work closely with other engineering teams to ensure compatibility between different satellite subsystems and optimize structural and thermal performance.

Moreover, the candidate may provide support in mission analysis areas when necessary. This will include activities such as the selection of physical components for the chosen architecture, defining mission and technical specifications for all subsystems, and assisting in their procurement. They will also be involved in system performance analysis and technical budget management, as well as managing internal and external interfaces for all mission elements.
Position Tasks and Responsibilities
The Space Mechanical Systems Engineer will be responsible for:
  • Modeling, simulating, and analyzing satellite components and structures.
  • Detailed design of satellite mechanical subsystems ensuring compliance with mission requirements.
  • Developing optimized structures to withstand the conditions of launch and the space environment.
  • Creating 3D models and assemblies of satellite components.
  • Integrating satellite components, ensuring compatibility between different subsystems.
  • Validating design through finite element simulations.
  • Collaborating with engineering teams to optimize the structural and thermal performance of the satellite.
  • Ensuring compliance with technical and regulatory mission requirements.
Providing versatile support in the following tasks:
  • Selection of physical components for the chosen architecture.
  • Definition of mission and technical specifications for all subsystems.
  • Managing internal and external interfaces for all mission elements.
Candidate qualifications and skills
The required experience and skills are:
  • Bachelor’s or Master’s degree in Aerospace, Mechanical Engineering, or a related discipline.
  • At least 2 years of prior experience in the mechanical and structural design of satellites or the aerospace industry (preferably in small satellite projects).
  • Knowledge and proficiency in advanced modeling and simulation tools such as SOLIDWORKS.
  • Fluent English (written and spoken).
The following qualifications and skills will also be desirable:
  • Hands-on experience with nanosatellite missions, including assembly, integration, testing, and operations.
  • Familiarity with space standards and regulations (ECSS, NASA, etc.).
  • Ability to work in multidisciplinary teams and collaborate with other engineers.
The applicant must have strong communication skills and be able to work autonomously and effectively while cooperating in a potentially international and culturally diverse team.
Additionally, the applicant must have strong analytical, organizational, and reporting skills, along with a proactive attitude for problem-solving and an interest in technological development.
About us

About Alén Space

Alén Space is a New Space company focused on the development of missions based on Nanosatellites as well as products and services related to them. Our mission is to help our clients to develop their business plan designing, manufacturing and operating satellites in order to execute the application they need.
While Alén Space is a new company, our team has been involved in several complete nanosatellite missions, from specification to delivery, during the last 15 years. Alén Space technical team is composed of systems engineers, electronic engineers, AIV engineers, software and operations engineers and project managers; with a large experience on IOD, communication, commercial and scientific missions, with private and public institutions such as the European Space Agency.
Alén Space’s value proposition resides in the flexibility and expertise of our team. We utilize our design and testing methodologies, which allow the use of components from various suppliers, to create the most suitable platform for the requested mission. During more than a decade, all our nanosatellites missions have been fully designed in-house, following the same multi-provider approach, resulting on a 100% success rate in orbit, for all launched missions.
At Alén Space, quality and flexibility in the design, manufacturing and testing are hallmarks of the company. The quality of the process is achieved through meticulous testing and verification processes, keeping traceability of all the executed activities. The flexibility is achieved thanks to the proximity relationship with our clients and to our supplier agnostic approach. This relationship aims not only at easing the communication process, but also at allowing our commercial clients to take an important role on the design aspects. In this line, we design the most flexible spacecraft platforms, to accommodate subsystem suppliers’ changes without heavily impacting the overall mission. Our systems and AIV engineers work closely with the client, in order to take decisions and involve them in the process.
Our team has enhanced a work method that applies the strict quality standards set by the European Space Agency (ESA) and the European Cooperation for Space Standardization (ECSS). All of our management, system engineering and AIV processes are based on those standards.
Quality, Flexibility, Scalability, Proximity, Expertise and Success define all Alén Space values.
