RF Engineer

At Delian, we design and build critical infrastructure for high-impact operations. Our mission is to protect the security and prosperity of the 1 billion people residing in European democracies and allied nations, through technological strength.

We are looking for an RF Engineer with a strong interest in electronic warfare (EW) to design and deploy radio systems that can operate—and survive—in contested electromagnetic environments.

You'll work on problems such as jamming resilience, signal detection, spectrum dominance, and adaptive communications, taking systems from concept to real-world deployment.

This is a hands-on, field-driven role where theory meets messy reality.

In this role you will get to

• Design RF systems for contested and degraded spectrum environments

• Develop and optimize anti-jamming and low-probability-of-intercept/detection (LPI/LPD) communication links

• Build and evaluate signal detection, classification, and geolocation capabilities

• Design and integrate RF front-ends for sensing and communications (filters, LNAs, PAs, mixers)

• Work with SDR platforms to prototype and deploy adaptive radio systems

• Perform link budgeting under adversarial conditions (interference, jamming, multipath)

• Conduct RF testing in both lab and real-world field environments

• Analyze and mitigate interference, intentional or otherwise

• Collaborate with autonomy and embedded teams to enable real-time spectrum-aware behavior

Must have experience

• Degree in electrical engineering, or related field

• Strong fundamentals in RF engineering and electromagnetics

• Practical experience deploying RF systems in real-world environments, iterating and improving them

• Experience with Altium Designer and/or Mentor Xpedition (Altium Designer preferred)

• Practical experience with some of the following:

• layout of mixed analog and digital designs

• high speed buses

• FPGA, DRAM and CPU designs

• power supplies and converters

• transmission lines, impedance-controlled traces and power traces

• Familiarity with SDRs (e.g., USRP, LimeSDR, HackRF) and RF measurement and test equipment

• Understanding of:

• Signal propagation in complex environments

• Modulation and coding schemes

• Link budgets and interference analysis

• Ability to debug RF issues in unpredictable, real-world conditions

• Excellent communication skills and ability to work effectively with others

Nice to have experience

• Experience in electronic warfare, signals intelligence (SIGINT), or spectrum monitoring

• Knowledge of:

• Jamming techniques and mitigation strategies

• Direction finding / geolocation techniques

• Spread spectrum, frequency hopping, or adaptive waveforms

• Experience with GNU Radio, MATLAB, or similar tools

• Background in UAV/drone communications or mobile platforms

• Experience with implementing embedded systems and support tooling (C/C++, Python)

• Experience with MIL-STD, commercial and IPC standards and design

• Understanding of design for manufacturability, assembly, and test
