Mechanical Design Engineer – Space Mechanisms

Department: Engineering
OCCAM Space is looking for a Senior Mechanical Design Engineer who enjoys working close to the product and turning complex requirements into reliable, manufacturable space hardware.

OCCAM Space designs and manufactures separation systems for satellites and launch vehicles.
We operate in a highly technical and industrial environment, with a strong product focus, an international outlook and a firm commitment to innovation, advanced engineering and reliability.
Take technical ownership of all aspects of hardware development and execution, from initial concept through manufacturing, integration, testing, launch and, where applicable, orbital operations.
Determine the applicable design loads and develop efficient structural solutions, using first principles to support critical architecture decisions for primary and secondary structures.
Perform and document the analyses required to substantiate design decisions, including hand calculations, finite element analysis —FEA— and kinematic analysis.
Identify, specify and select commercial off-the-shelf components that meet the technical and functional requirements of the design.
Incorporate manufacturing considerations from the conceptual design phase, evaluating different manufacturing methods such as machining, forming, welding, composites and other alternatives.
Proactively drive the evolution and technical maturity of the hardware, coordinating with end users, stakeholders and adjacent engineering teams to ensure that every element of the system develops consistently.
Produce engineering drawings and technical specifications containing all the information required for manufacturing, inspection and integration.




Prepare test plans and provide direct technical support during execution to ensure the successful structural qualification and acceptance testing of the hardware.
Work with OCCAM Space’s internal manufacturing team and external suppliers to procure materials, manufacture parts and complete assemblies.
Update designs, drawings, analyses and technical documentation to incorporate changes, test results and continuous improvements.

Bachelor’s degree in Mechanical, Aerospace or Industrial Engineering, or a related technical field.
Proficiency in CAD software and the ability to learn new tools. Experience with CATIA and SolidWorks will be particularly valued.
Demonstrated experience modelling complex geometries using surfacing, lofting and other advanced 3D modelling techniques.
Experience across the hardware development lifecycle, including conceptual design, manufacturing, integration and testing.
Ability to produce and interpret manufacturing drawings, technical specifications and design documentation.
Professional working proficiency in Spanish, both spoken and written, to communicate effectively and work collaboratively in OCCAM Space’s day-to-day environment.

Master’s degree in Mechanical Engineering, Aerospace Engineering or a related field.
At least 10 year of experience in the mechanical design and analysis of hardware that has been manufactured, tested or flown as part of a space mission.




At least 3 years of experience applying Geometric Dimensioning and Tolerancing —GD&T;— to designs and manufacturing drawings.
At least 3 years of experience performing and documenting Finite Element Analysis —FEA—.
Ability to carry out structural and basic thermal analyses to support design decisions.
Knowledge of manufacturing processes used for mechanical components, including machining, forming, welding and composite manufacturing.
Experience in hardware qualification and acceptance testing.
Knowledge of the space industry and its design, manufacturing, traceability and verification requirements.
A creative, self-driven and proactive approach, with the autonomy to take ownership of projects and lead them through to completion.

Permanent, full-time employment contract.
~ Ownership of the complete product lifecycle, from initial concept through manufacturing, integration and testing.
~ Continuous training and hands-on learning.
~ Professional development aligned with your skills, experience and interests.
~ Flexible compensation plan, including childcare vouchers, meal and transport cards and private health insurance.
~ Adaptable working hours, with arrival between 8:00 and 9:30 a.m. Export control
S. export control regulations —including the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR)— as well as European Union and Spanish legislation, including Regulation (EU) 2021/821, Law 53/2007 and Royal Decree 679/2014. Any difference in treatment arising from these requirements shall be exclusively based on the legitimate purpose of complying with legal export control obligations and shall be applied as an appropriate, necessary and proportionate measure, in accordance with Article 4.2 of Spanish Law 15/2022 of 12 July on equal treatment and non-discrimination.
