Senior RF/Microwave Engineer

ARQUIMEA

Madrid, Spain

Scope:

We are seeking a Semi-Senior RF Engineer to contribute to the definition, development, and validation of complex RF and electronic systems.

The role focuses on system-level design, board-level design, flow-down requirements, architecture trade-offs, and technical coordination between RF, digital, power, mechanical, and software domains.

The ideal candidate has hands-on experience bridging subsystem/board design and overall system performance, ensuring compliance with functional, performance, and environmental requirements.

This position requires a strong analytical mindset, practical engineering judgment, hands-on experience, and close collaboration with multidisciplinary teams throughout the full product lifecycle.

Responsibilities:

• Define and maintain system-level architecture for RF and electronic systems.
• Translate customer and mission requirements into system and subsystem specifications.
• Perform system-level trade-off analysis (performance, cost, power, complexity, risk)
• Define and manage key system budgets:
  • RF link budget
  • Noise figure and gain budget
  • Power consumption and thermal budget
  • Frequency plan and spur analysis
• Coordinate interfaces between subsystems:
  • RF, analog, digital, power, firmware, and mechanical
  • Definition and control of ICDs (Interface Control Documents)
• Support RF system design activities:
  • Receiver and transmitter architectures
  • Frequency conversion chains
  • LO, PLL, and clocking strategies
• Collaborate with hardware teams to ensure subsystem designs meet system intent
• Support system-level simulations and analysis using appropriate tools
• Participate in design reviews
• Support system integration, bring-up, and debugging activities
• Analyze test results and correlate measurements with system-level expectations
• Support verification and validation plans and procedures
• Interface with project management and stakeholders on technical topics
• Board design for RF is a plus
• Experience in space or high-reliability systems is a plus.

Required Education and Skills:

• Bachelors degree in Electrical/Electronics Engineering or equivalent
• 3+ years of experience in RF/microwave
• Hands-on experience with RF systems and components
• Desirable knowledge in PCB design tools such as:
  • Altium Designer (preferred)
  • Cadence Allegro / OrCAD
  • Mentor Xpedition
• Proficiency with RF design and simulation tools:
  • ADS
  • HFSS
  • CST
  • AWR Microwave Officce
• Ability to read and interpret RF schematics and simulation results
• Ability to read and understand parts datasheets
• Experience working with multi-disciplinary engineering teams.
