Subsea Design Engineer (Mechanical) -

We’re a technology company that is transforming operations at sea to enable people and the planet to thrive.

We are open-minded and fearless in our approach to innovation and don’t believe in boundaries. We challenge everything and have massive ambitions to drag ageing industries into the tech era.

We take safety, equality and education very seriously, and our responsibilities don’t stop at our front door. Our business is built on the belief that there’s definitely a more environmentally responsible way to operate at sea.

We only employ the best people. People with a desire for excellence, a curious nature, people who are thoughtful, humble, collaborative and accountable.

We reward our people well. Beyond what’s usually considered to be the ‘market average’.

The opportunities for people in our business can be limitless, spanning a multitude of disciplines and open to all, regardless of background and experience level.

We’re not your average workplace.


Ocean Infinity is seeking a Subsea Design Engineer who will join the Subsea Technologies Team. The Subsea Technologies team is responsible for the specification, engineering, and delivery of all robotic systems deployed below the surface of the sea, including AUVs, ROVs, hybrid vehicles, towed systems, and other marine robots, as well as their respective supporting equipment (LARS & deck handling interfaces). In addition, Subsea Technology is responsible for the development of control systems technology to enable remote operations of these systems as well as data (telemetry and acquired) flow management for the full spectrum of applications, including inspection, mapping, geophysical, geotechnical, oceanography, scientific research and defense.

The Subsea Design Engineer will be flexible in their ability to support a broad range of engineering tasks. This will include supporting/leading computational fluid dynamic (CFD) modelling, Orcaflex studies, concept modeling of prototypes using 2D and 3D CAD software, vehicle body design, hydraulic system design and sensor integration. The candidate should be familiar with the design principles required to reduce noise and interference on sensitive electronics, sonars, and navigation instruments. Knowledge of electrical system design and integration is desirable but not essential.

This position requires a minimum of 5 years’ professional experience, the candidate will have worked in a similar design engineering role, with ROV/AUV/Tooling design experience. The ideal candidate will be an accomplished practical engineer who has a good understanding of both electrical and hydraulic actuation along with hydrodynamic design experience.

The right candidate will need to be an enthusiastic team player, already committed to behaving in an ethical manner, championing fairness, equality and always demonstrating sincere safety leadership; you will be attracted by an organisation which recognises people as being integral to our progressive systems development. You will have unlimited opportunity to contribute energy and ideas in a dynamic and technically challenging environment.

The Armada project is delivered and operated by Ocean Infinity Group, a world leading provider of ocean data, search and recovery services. You will be joining an exceptional team united in their passion for enhancing value for our clients through smart thinking and invention. The work we do is varied, challenging, high profile and always highly rewarding.
