Protecting What Matters. Powering The Future Of Naval Technology.

Ultra Maritime is a global leader in advanced maritime defence solutions. We operate at the forefront of innovation, delivering technologies that protect lives, secure nations, and enable a safer, more sustainable world. At Ultra Maritime, we’re committed to helping you reach your full potential. If you meet some, but not all of the criteria, we still encourage you to apply. We value passion, curiosity, and the drive to make a difference. To support your growth, we offer industry‑leading development programs, and mentorship from some of the brightest minds in maritime technology.

What can you expect from us?

More than just a job, we offer a mission. More than just a workplace, we provide the opportunity to protect lives, advance technology, and shape the future of maritime security. We know that great work happens when people are supported to live well — not just work hard. Your life outside of work matters just as much as what you do inside it, which is why flexibility is built into how we operate.

Where possible, we actively support flexible working arrangements, whether that means a hybrid setup, remote working, or the structure and collaboration of being on‑site. We’re open to conversations about part‑time roles, compressed hours, and bespoke working patterns that fit your lifestyle — because one size doesn’t fit all.

Across each of our sites we go even further — offering a 9‑day fortnight giving you an extended weekend every other week and more time to recharge, pursue your passions, and spend time doing what matters most.
