• Produce 3D CAD models, technical drawings, assembly documentation, and manufacturing specifications.
• Select appropriate materials, components, and manufacturing processes, considering mechanical performance, corrosion resistance, durability, and cost.
• Support prototyping and manufacturing activities, including 3D printing, CNC machining, and conventional machining processes.
• Perform mechanical calculations and engineering assessments related to structural behaviour, loads, dynamics, and mechanical performance.
• Participate in the assembly, integration, testing, and validation of mechanical prototypes and systems.
• Identify and resolve mechanical design, manufacturing, and integration challenges.
• Work with multidisciplinary teams to ensure the compatibility of mechanical systems with electronic, sensing, and control components.
• Contribute to the continuous improvement of mechanical designs, manufacturing workflows, and system reliability.
• Prepare technical documentation and report on design progress, testing results, and engineering developments.

Expertise Needed

• Degree in Mechanical Engineering, Naval Architecture, Marine Engineering, or a related field.
• Strong knowledge of mechanical design principles, including statics, dynamics, mechanisms, and structural behaviour.
• Practical experience with 3D CAD software such as Onshape, SolidWorks, Rhino, FreeCAD, Fusion 360, Inventor, Siemens NX, or equivalent.
• Knowledge of engineering materials, including metals, polymers, composites, and their mechanical properties.
• Understanding of manufacturing processes, including 3D printing, CNC machining, conventional machining, and mechanical assembly.
• Experience in mechanical component design, dimensioning, tolerancing, and preparation of technical drawings.
• Ability to perform mechanical calculations and assess loads, stresses, deformation, and dynamic behaviour.
• Practical problem-solving skills and the ability to translate engineering concepts into functional prototypes.
• Strong organisational and communication skills, with good written and spoken English.
• Authorisation to work in Portugal.

Added Value (two of any of these skills are needed)

• Experience designing mechanical systems for marine or underwater environments.
• Knowledge of corrosion, waterproofing, sealing solutions, and material compatibility in marine environments.
• Experience with floating structures, buoyancy, stability, or hydrodynamic principles.
• Experience with motor-driven mechanisms, actuators, transmissions, bearings, and mechanical power systems.
• Experience with finite element analysis (FEA), computational fluid dynamics (CFD), or other engineering simulation tools.
• Hands-on experience with prototyping, 3D printing, CNC machining, or workshop equipment.
• Knowledge of design for manufacturing and assembly (DFMA).
• Experience integrating mechanical systems with electronics, sensors, or control systems.
• Experience with field testing, marine equipment deployment, or oceanographic campaigns.
• Basic knowledge of programming, Linux, or Git.
