RF Electronics Engineer

We build Radio Units (RUs) that work as high\-speed, secure, jam\-resistant data pipelines for defence and dual\-use applications — the connective tissue for UAV C2, deployable 5G, and tactical awareness systems.

Our pipeline is full of customers — defence primes, armed forces, industrial operators — who want our RU in their hands. Demand is ahead of us. Our job now is to turn boards into working hardware, fast, and ship them.

We are now looking for Electronics Engineer to join the team and increase the velocity \- someone who can confidently build, rework, test, and troubleshoot microwave radio hardware across our product range, and operate independently while doing it.

You'll be the person who turns boards into working hardware and tells the design team what reality looks like.

What you'll actually do

• RF Validation \& Characterization: Own the bench testing for new PCB revisions. You’ll use VNAs, spectrum analyzers, and signal generators to characterize RF chains and ensure performance aligns with simulations and link budgets.


• Design Assistance: Support the senior design team by performing schematic captures, component selection, simulation (CST and/or ADS) and circuit modifications


• Bring up new PCB revisions: power\-on, functional test, characterisation against spec.


• Solder and rework fine\-pitch SMD and RF components, including 0201 components and QFN packages. Modify boards when a design change needs testing before a respin.


• Troubleshoot hardware failures methodically. Isolate the fault, narrow it down, document what you found.

What we're looking for

You should be credibly strong on most of the must\-haves:

• Confident solderer. Fine\-pitch SMD, QFN, rework of RF components — you've done this and you're good at it.


• Comfortable with RF/microwave test equipment. VNA, spectrum analyser, signal generator, oscilloscope. You set them up, calibrate them, and trust the results.


• Enough RF/microwave understanding to troubleshoot without a script. You recognise unexpected spurs, you know what a PLL lock failure looks like, you can tell a real signal from a measurement artefact.


• Systematic troubleshooting. You isolate faults methodically and explain how you got there.


• 3–5 years in a hands\-on lab or bring\-up role.

• Serial protocol debugging (SPI, I2C, UART).


• FPGA boards or high\-speed digital hardware (ADC/DAC, Ethernet).


• Gimbal or motor system experience.
