About Orbion

At Orbion, we are building next next-generation radar systems designed to make air and ground operations safer, smarter, and more affordable.

We are a deep-tech startup developing Silencio , a low-SWaP phased-array radar platform designed for:

• Air-to-Air Detection, Avoidance & Tracking for autonomous and remotely operated aerial systems,

• Ground-to-Air Detection & Monitoring for airspace awareness and critical asset protection,

• Dual-use civil and governmental security applications.

Most radar systems today are incremental: larger antennas, higher power consumption, heavy installations, and limited adaptability.

Orbion is developing compact, intelligent radar systems that operate where Physics, RF, real-time processing, and harsh operational environments collide. Our architecture combines high performance RF circuitry, active phased-array antennas, embedded processing, and classification algorithms into scalable radar platforms.

Your Role

We are looking for an RF/Antenna Engineer to take ownership of the RF core of Silencio. This is a hands-on engineering role; you will design, build, measure, debug, iterate, and improve hardware that will be deployed at critical infrastructure sites.

You will act as a technical integrator between mechanical, FPGA, embedded software, and digital hardware engineering teams — working directly with them from bench validation through system integration and field deployment.

What You Will Build

RF Architecture & Front-End

• Design TX/RX chains and PLL circuits,

• Perform gain and noise budgeting,

• Integrate LNAs, PAs, PLLs, mixers, and filters,

• Drive RF trade-offs across performance, power, and size.

Phased-Array & Antenna Integration

• Support antenna design activities from unit element selection to beam-steering,

• Contribute to calibration strategies,

• Collaborate with DSP on hardware–algorithm optimization.

Testing & Validation

• Execute RF validation campaigns,

• Perform S-parameter and noise measurements,

• Develop radiated measurement setups,

• Lead tuning and translate failures into design improvements.

Who You Are

• You have strong analytical skills and understand EM theory,

• You thrive on ownership and iteration (“design → test → improve”),

• You have extremely high standards for technical excellence,

• You are comfortable with uncertainty and early-stage challenges,

• You want to work on technology that matters in high-stakes environments,

• You value engineering depth over bureaucracy.

What We Offer

• A key technical role in a fast-growing deep-tech company redefining compact radar systems in dual use applications,

• Collaboration with world-renowned experts in radar technology, RF engineering, and applied signal processing,

• Opportunities to present work at international conferences, demonstrations, and industry events,

• Competitive salary based on experience,

• Equity package possible, depending on hours committed and duration of engagement,

• A culture where ambition, curiosity, technical excellence, and responsibility are rewarded,

• Hybrid working possible up to 25%.

Note: Applicants must have valid work authorization in the Netherlands; visa sponsorship is not available.
