RF & Communications Engineer
Platform EMC • Link engineering • Antennas • Secure C2
TeleBortiX builds state-of-the-art airborne systems.
This role owns the electromagnetic and communications architecture of our aircraft end to end, across production airframes and the flying laboratories that support them. Our platforms are demanding electromagnetic environments by construction: distributed inverters switching onto high-voltage DC buses, long HV harness runs through composite structure that offers no helpful ground plane, and the GNSS antenna, C2 datalink, telemetry radio, transponder and ADS-B receiver all located within a few metres of those sources.
You determine antenna placement and substantiate it with pattern data. You set the isolation requirements and defend the figures. You select the radio stack, own the latency budget through it, and take each link from budget through flight test to measured characterisation. The role combines full-wave simulation with hands-on bench and flight measurement, and carries the authority to reroute harnesses,



relocate antennas and specify filters.
Key responsibilities
Platform EMC integration: emitter–receptor matrix across all transmitters (fundamental, harmonics to the fifth, spurious mask) and receivers (sensitivity, selectivity, blocking, damage threshold); antenna isolation matrix with simulated S21 per pair validated by measurement, carrying required-isolation and margin columns; I/N margin tables against a stated criterion; third-order intermodulation mapped onto the frequency plan.
Installed antenna performance: azimuth and elevation gain contours as mounted on the airframe. For GNSS, gain above 5–10° elevation, axial ratio, and multipath with rotors turning.
GNSS interference budget: HVDC and inverter broadband noise assessed against RTCA DO-235B at L1 and L5. Typically the first deliverable and the highest-risk item on the programme.
Harness, shielding, bonding and grounding architecture, including common-mode current
