Senior Hardware Engineer – Space & Defence

Description

Job Summary: We are seeking a Senior Hardware Development professional for Space and Defence projects, with strong technical involvement and design participation. Key Highlights: 1. You will participate in strategic Space and Defence projects. 2. You will be part of a multidisciplinary team in a demanding technical environment. 3. We foster career paths where deep technical knowledge is the central pillar. At **Sener Aerospace and Defence**, the sustained growth of our Space and Defence programmes drives us to continue expanding our team. We seek to incorporate a **Senior Hardware Development professional** at our Tres Cantos (Madrid) or Getxo (Biscay) facilities, who wishes to join a clear phase of technological and industrial expansion. You will participate in strategic Space and Defence projects, developing high-reliability electronic equipment that forms part of critical systems for institutional missions and top-tier defence programmes. This is a position of **high technical responsibility**, designed for professionals who enjoy designing, making technological decisions, and mentoring less experienced engineers — all while remaining actively engaged in hands-on technical work. You will work in a demanding and collaborative technical environment, as part of a multidisciplinary team where technical expertise combines with the ability to share knowledge and lead by example. You will maintain an active role in design while contributing technical judgment to key project decisions. **Your Responsibilities:** You will join a multidisciplinary team (hardware, control, software, and mechanics) developing electronic control units for antenna pointing systems, robotic coupling and anchoring mechanisms, telescope focusing and scanning systems, among others; participating in highly demanding projects from initial phases through final validation. Specifically, your responsibilities will include: * Analysing and decomposing **system and equipment requirements**, actively participating in defining technical solutions compliant with Space and Defence standards. * Performing **detailed electronic design** of equipment, both at schematic level and providing technical support for PCB component placement and routing. * Conducting **analogue and digital simulations**, evaluating design behaviour under various operational scenarios. * Defining and reviewing **hardware validation procedures**, ensuring compliance with functional, environmental, and reliability requirements. * Executing **functional tests on equipment**, and participating in **environmental test campaigns** (thermal, vibration, etc.), collaborating in result analysis. * Preparing and maintaining associated **technical documentation** (design, validation, technical justifications, reports, and project deliverables). * Participating in **technical reviews with clients**, contributing judgment and experience to design decision-making. * Acting as the **technical reference within the team**, collaborating with less experienced profiles and contributing to overall project technical coherence, while maintaining direct involvement in design. **What We Expect From You:** We seek a **senior professional with a solid technical foundation**, eager to further develop expertise in hardware design for complex Space and Defence systems, and who enjoys sharing knowledge and providing technical judgment within the team. We especially value professionals who wish to combine deep technical expertise with active participation in design decisions and mentoring of less experienced colleagues. Essential Requirements: * University degree in Electronic Engineering, Industrial Engineering or Telecommunications Engineering. * Advanced level of English. * **Minimum 8 years’ experience** in similar electronic hardware development roles. * Demonstrable experience in detailed design of analogue and power circuits, as well as digital circuit design, including communication buses, memory interfaces, and FPGAs. Additionally, the following will be valued: knowledge of actuators and sensors; motor control design; PCB design… as well as proficiency with tools such as (Matlab / Simulink), Altium, Pspice/LTspice, VHDL, C, C\+\+, Matlab/Simulink, Python and Labview. Also essential is familiarity with defence and space analysis methodologies (Parts Stress Analysis (PSA), Worst Case Analysis (WCA), Reliability, FMECA, Fault Tree Analysis, Radiation effects…). **What We Offer You:** These are some of the benefits you will enjoy at Sener: * Join a multidisciplinary and highly qualified team working on internationally recognised, technologically innovative projects. * Continue your professional development with us and access a wide range of training opportunities (technical, soft skills, languages…). * Take care of your wellbeing with our physical and emotional wellness programme: sports activities, workshops, medical services, physiotherapy, etc. * Optimise your salary with our flexible remuneration plan (meal vouchers, private health insurance, nursery vouchers…) and benefit from our life and accident insurance. * Flexibilise your way of working! We offer flexible working hours, teleworking policies, and coworking spaces. * Discount portal for you and a dedicated onboarding programme for our international employees. * We promote equal opportunities, diversity and inclusion for all individuals and hold certification as a Family-Responsible Entity (efr). Furthermore, through the Sener Foundation, we collaborate in initiatives that encourage knowledge-seeking and contribute to socially responsible engineering development. We offer you the opportunity to join a rapidly expanding environment, with access to strategic projects and long-term career prospects. At **Sener**, professional progression for technical profiles does not mean stepping away from engineering: we foster career paths where deep technical knowledge and hands-on experience remain the central pillar of development.
