ARQUIMEA , we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors. Our areas of activity are Aerospace, Defense & Security, Big Science, Biotechnology and Fintech.
We are looking for a Mechanical Engineer to join the Robotics Mechanical Design Team within PULSAR HRI , ARQUIMEA's robotics area focused on high-performance motors, actuators and advanced robotic systems.
The successful candidate will work on the design, development, integration, testing and validation of mechanical subsystems for complex mechatronic and optronic platforms. The candidate will contribute to the development of systems including ruggedized assemblies that may integrate optical sensors, actuators, bearings, transmissions, enclosures, thermal management components and mechanical interfaces. These systems must operate reliably in technically demanding environments and require a strong balance between mechanical performance, manufacturability, robustness, maintainability and practical testing.
This role is focused on hands‐on mechanical engineering : turning concepts into CAD models, drawings, prototypes, test setups, validated assemblies and production‐ready designs. The candidate will work closely with software, control, electronics, systems, manufacturing and testing teams to ensure that mechanical solutions are technically sound, buildable, testable and aligned with system‐level requirements.
The candidate is not expected to be a senior expert in every area . We are looking for someone with solid mechanical engineering fundamentals, good technical judgement, curiosity, practical problem‐solving ability and a willing disposition to learn, build, test and improve real systems.
Design mechanical parts, assemblies and subsystems for robotic, mechatronic and optronic platforms.
Create and maintain 3D CAD models, assemblies, 2D manufacturing drawings, bills of materials and technical documentation.
Design mechanical interfaces for cameras, optical payloads, sensors, motors, actuators, electronics, cable routing, connectors and auxiliary subsystems.
Work on prototype design, assembly, integration, testing,



debugging and iterative improvement of mechanical solutions.
Participate in mechanical testing and validation activities, including functional testing, alignment checks, load tests, vibration-related evaluations, thermal checks, endurance tests and assembly verification.
Support tolerance analysis, material selection, bearing selection, fastening strategies, sealing approaches and mechanical architecture decisions.
Collaborate with manufacturing suppliers and internal teams to ensure that parts can be machined, assembled, inspected and maintained effectively.
Apply design-for-manufacturing, design-for-assembly and design-for-test principles from early development stages.
Identify mechanical risks, diagnose failures or performance limitations and propose practical corrective actions.
Contribute to the integration of mechanical systems with electronics, embedded devices, control software, sensors and actuation technologies.
Support the preparation of prototypes, test benches, laboratory setups and field-test configurations.
Provide feedback to actuator, motor, electronics, software and control teams based on real mechanical integration constraints and system-level behaviour.
Collaborate in multidisciplinary technical planning with mechanical, electronics, software, control, systems, testing, manufacturing and product teams.
Maintain clear technical documentation, including design rationale, test results, assembly procedures and lessons learned.
Degree in Mechanical Engineering, Industrial Engineering, Mechatronics, Aerospace Engineering or similar.
~Strong mechanical engineering fundamentals, including statics, dynamics, materials, tolerances, manufacturing processes and mechanical design principles.
~ Good practical ability with 3D CAD tools and mechanical assembly design.




~ Ability to produce clear 2D drawings and define appropriate tolerances, materials, finishes and manufacturing requirements.
~ Experience designing mechanical parts for machining, sheet metal, additive manufacturing or other common manufacturing processes.
~ Practical understanding of mechanical assembly, prototyping, troubleshooting and testing.
~ Basic understanding of mechatronic systems involving motors, actuators, sensors, electronics and control interfaces.
~ Ability to work with evolving requirements, incomplete information and technical uncertainty while maintaining a practical engineering approach.
~ Good communication skills and ability to collaborate effectively with software, electronics, control, systems, manufacturing and testing teams.
~ Fluent English, both written and spoken.
~ Experience with ruggedized mechanical design for aerospace, defence, naval, robotics, industrial or outdoor environments.
Experience integrating motors, actuators, encoders, sensors, cameras, IMUs, rangefinders or electronics into mechanical assemblies.
Familiarity with mechanical simulation tools, including basic FEA for stiffness, stress, modal or thermal analysis.
Knowledge of GD&T;, tolerance stack‐up analysis and inspection methods.
Experience with prototype manufacturing, supplier interaction, assembly procedures and mechanical verification plans.
Experience designing test benches, fixtures, alignment tools or validation setups.
Familiarity with cable routing, connector integration, electronics packaging and mechanical‐electrical interface constraints.
Experience with product development from concept to prototype, validation and production‐oriented design.
Background in robotics, aerospace, defence, industrial machinery, precision equipment or other technically demanding environments.
Basic understanding of control systems, actuation technologies or robotic system integration.
The idóneo candidate is someone who enjoys building real systems, learning from tests, solving practical engineering problems and working in close contact with multidisciplinary teams.
