Interoperable, ultra-low profile, high-gain satcom on the move


Senior/ Lead/ Principal Software Engineer

We’re looking for an experienced Lead Software Engineer to take a key role within the software engineering team developing embedded software for a novel phased array antenna system for aviation, maritime and land satellite communication application.

As part of a Central London-based company, the successful candidate will apply their technical skills, leadership and experience to work with the team to rapidly design, develop, and test embedded C firmware (at the baremetal, RTOS, or application level). The candidate will need to be able to work through the full development lifecycle, from de-risking, prototyping, development, integration, and testing.

Look up and lock on to a bigger future, fast

As the original disruptors in solid-state satcom-on-the-move antenna, Hanwha Phasor is rewriting the book on phased arrays. It’s one of the toughest challenges in satcom. And, so far, we are the only team to demo multi-axis capability in real world conditions.

Now we’re closing in our goal: active electronically-steered antennas (AESA) for super-fast, super-reliable connectivity—GEO, of course, but LEO, MEO and HEO too.

Our inventive combination of digital and analogue architectures enables highest performance gain for lowest power and lowest profile, while our modular approach enables configurable apertures for the full range of enterprise customers on the move – in the air, on land or at sea.

Backed by Hanwha Systems, the Korean technology giant with a growing presence in global satcom, we are attracting formidable partners: we have appointed a world-class, global manufacturing partner, and two of the world’s best FABs are working on our chips.

So, what does that mean for you? All the fast-paced opportunity you’d expect from a challenger, plus the systems, processes and investment you’d want from an established industry leader.
