🛰️ Indra Space – Leading the Next Generation of Space Systems 🛰️

At Indra Space, we are on a mission to redefine the European space industry by delivering high-performance small satellite solutions for LEO missions. Our ambition? To become a leading company in end-to-end satellite systems, driving innovation in:

• 📡 Position, Navigation & Timing (PNT)

• 🔒 Secure Communications

• 🌍 Earth Observation & ISR

• 🛰️ Space Domain Awareness (SDA) and Space Traffic Management (STM)

• 🔭 Science & space exploration

As the Space Business Unit of Indra Group, we combine cutting-edge technology with a full value chain approach—from satellite design and integration to ground segment and operations. With the integration of Deimos and strategic participation in Hispasat and Hisdesat, we are scaling Europe’s space autonomy and contributing to flagship programs like IRIS², Galileo, EGNOS, and Copernicus.

🎯 What We’re Looking For

We are looking for a skilled RF Design Engineer with strong experience in RF transmission and reception architectures across different frequency bands.

  • Analog simulation tools (LTSPICE or similar).
  • Hands‑on experience with RF lab instrumentation (spectrum/network analyzers, signal generators).
  • Experience in oscillators and PLL systems.
  • Experience in modulators, demodulators, and frequency converters.

⭐ Optional / Nice‑to‑Have

• Experience in satellite communication processing and architectures.

• Design skills for satellite‑embedded systems.

• Knowledge of ECSS space standards or similar.

• Familiarity with space‑grade components.

• Experience with VCOs, PLLs, and RF synthesizers.

• Knowledge of antenna design.

• Electromagnetic simulation tools (CST, HFSS).
