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


Embedded Software Architect

We have an exciting opportunity for an experienced Embedded Software Architect to lead our embedded software architecture team from architecture definition through to certification. You will lead a team to design, build and implement a software architecture that can be certified to Aircraft industry standards.

Reporting to the Senior Head of Systems Engineering, you will oversee our software development efforts by proposing a future proof software architecture and an associated development roadmap.

Solution-oriented, you are enthusiastic about making well designed products and have an attention to detail. You will contribute towards the success of Hanwha Phasors satcom terminals by delivering complex and innovative products into the aerospace, maritime and land mobile industries in a dynamic London-based technology company.

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.
