Senior Electronic Board Layout Designer

Expleo is a global engineering, technology, and consulting partner helping businesses innovate, transform, and deliver high‑quality products and solutions. With expertise spanning aerospace, automotive, transportation, telecommunications, financial services, and life sciences, we support clients in solving complex engineering challenges while accelerating innovation. Our teams combine deep technical knowledge with a hands‑on mindset, working collaboratively to drive measurable impact and operational excellence.

Expleo is seeking a Senior Electronic Board Layout Designer to strengthen our product development activities for advanced communication and embedded systems. You’ll own the full PCB layout cycle for complex, high‑reliability multi‑layer boards, translating electrical/RF/mechanical requirements into production‑ready designs, and releasing complete manufacturing packages in close collaboration with cross‑functional teams in Lausanne.

• →Own end‑to‑end PCB layout, from requirements and constraints through placement, routing, checks, documentation, and manufacturing release. 
• →Design complex multilayer PCBs (10–20+ layers) including high‑speed interfaces (Ethernet/DDR), FPGA‑centric subsystems, mixed‑signal, power distribution, and RF sections where applicable. 
• →Apply SI/PI and EMC best practices: controlled impedance, differential pairs, return paths, length matching, crosstalk mitigation, and decoupling. 
• →Work hands‑on in Altium Designer / Altium 365, using hierarchical design, rooms/replication, templates, and robust library management. 
• →Generate and release complete PCB/PCBA manufacturing data via PLM, and drive DFM/DFA/DFT with fabrication and EMS partners. 
• →Collaborate closely with HW, RF, Mechanical (SolidWorks), and Embedded teams, supporting prototypes, root‑cause analysis, and ECN/PCN updates. 

• 10+ years of professional experience designing complex, multi‑layer PCBs (12+ layers) in highly regulated or demanding environments such as aerospace, medical, automotive, or industrial electronics.
• Expert proficiency with Altium Designer/Altium 365, including hierarchical design, room‑based replication, and advanced layout workflows.
• Experience working with high‑speed digital interfaces, FPGA placement and routing, mixed‑signal constraints, and low‑noise board design.
• Strong understanding of Design‑for‑Manufacturing, Design‑for‑Assembly, and Design‑for‑Testing/Maintenance principles. 
• Solid library management experience and knowledge of PCB stack‑ups, controlled impedance routing, and signal integrity fundamentals. 

• Clear, concise communication skills in English (written and verbal). 
• Ability to work at least 3 days per week onsite in Lausanne

• Familiarity with simulation tools such as Ansys SIwave and LTspice. 
• Experience collaborating with RF engineers working on 20–30 GHz systems. 
• Prior work with embedded software or programmable logic engineers.
