? Mollet del Valles (Barcelona), Spain

? Hybrid Working

? General tech company founded in 2011

? Our mission is to shape the future through technology The role

As an Antenna / RF Design Engineer, you will be responsible for the end-to-end design, simulation, and validation of antennas and RF front-end systems. You will play a key role in ensuring the technical and functional feasibility of our products, working closely with a multidisciplinary team to guarantee that all technical specifications, quality standards, design to cost focus and project timelines are strictly met.

Key Responsabilities

- Antennas and RF Circuit Design: Take part in the design and development of antennas and RF front-end architectures from MHz to mmW application: front ends, LNA, RF filters including Power Amplifiers (PAs), Low Noise Amplifiers (LNAs), filters, mixers, combiners, antennas among others, following the IDS (Idneo Development System)
- Electromagnetic Simulation: Conduct RF and EM simulations using softwares like ADS, Microwave Office, HFSS, Feko.
- Laboratory Testing & Validation: Define and execute test plans for RF / HW verification in the RF laboratory during each development loop. Utilize advanced instrumentation including Vector Network Analyzers (VNAs), Spectrum Analyzers, radio generators and perform antenna measurements in anechoic chambers.
- PCB Layout: Oversee and guide the PCB layout routing for RF circuits, ensuring strict RF guidelines for signal integrity, grounding, impedance and isolation for all RF traces.
- Design Optimization: Analyze and optimize RF designs to maximize performance while keeping focus on cost.
- Lifecycle & Industrialization:



Collaborate with the manufacturing and industrialization teams to ensure a successful transition of prototypes into mass production.
- Technical Documentation: Manage product modifications and generate comprehensive technical documentation, design reports, and test procedures throughout the development cycle.

(*) The described functions are only the most representative for this position; therefore, they should not be understood as all the inherent functions related to this job position.
- Experience & Technical Knowledge: At least 2+ years of solid experience designing Antennas and/or RF front ends (PAs, LNAs, filters, mixers, combiners)
- Education: Bachelor’s, Master’s, or Ph.D. degree in Telecommunications Engineering, Electronics Engineering, or a closely related field with a specialization in RF/Microwave engineering.
- Software Tools: Proven experience in EDA simulation software (e.g., AWR, ADS) and EM simulation tools (e.g., FEKO, HFSS).
- Languages: Advanced level of English (written and spoken) for international technical collaboration.
- Availability: Willingness to travel occasionally for project collaboration and testing campaigns.

Highly Valued

- Prior professional experience in RF design for Automotive, Aerospace or Defense applications (e.g., satellite communications, radar systems, or compliance with military / automotive standards).
- Hands-on experience in Antenna design, integration, and tuning.
- Solid understanding of wireless communication technologies and standards (LTE, 5G, UWB, Bluetooth, Wi-Fi, GNSS, Broadcasting, V2X, Radar, ….)
