What will you do?

Take technical ownership of all aspects of hardware development and execution, from initial concept through manufacturing, integration, testing, launch and, where applicable, orbital operations.

Define and maintain the complete technical roadmap for your hardware throughout its entire lifecycle.

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.

Document and communicate design assumptions, constraints, interfaces and requirements, ensuring they are understood and remain valid as the product evolves.

Coordinate with the teams responsible for related designs -including adapters, dispensers, release actuators and separation systems and subsystems- to ensure compatibility between components and interfaces.

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.

What are we looking for?

Bachelor’s degree in Mechanical, Aerospace or Industrial Engineering, or a related technical field.

At least 3 years of professional experience in mechanical design and hardware development.

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.

Experience working collaboratively with multidisciplinary teams.

Ability to identify and communicate technical challenges, justify design decisions and resolve issues throughout the product development process.

Professional working proficiency in Spanish, both spoken and written, to communicate effectively and work collaboratively in OCCAM Space’s day-to-day environment.

Preferred skills and experience

Master’s degree in Mechanical Engineering, Aerospace Engineering or a related field.

At least 1 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 documented 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.

What do we offer?

A gross annual salary of €45,000 to €70,000, depending on experience, technical expertise, level of responsibility and overall fit for the role.

Direct involvement in the development of mechanisms and hardware for real space missions.

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.

Adaptable compensation plan, including childcare vouchers, meal and transport cards and private health insurance.

Flexible working hours, with arrival between 8:00 and 9:30 a.m. and genuine flexibility to organise your working day.

22 working days of annual leave.

6 additional personal days.

24 and 31 December off.

Your birthday off.

Export control Due to OCCAM Space’s collaboration with U.S. customers, certain activities and technical information may be subject to U.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. Accordingly, access to controlled technology in certain positions requires compliance with the eligibility requirements established by the applicable regulations and authorisations.

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.
