Marine Technician (Hydrotwin Fleet Technician)

Company

At blueOASIS, we develop technology that helps protect and better understand our oceans. We are a fast-growing technology company creating sustainable solutions for the blue economy. Our expertise spans offshore engineering, underwater acoustics, smart ocean modelling, environmental monitoring and digital twins, helping organisations monitor, understand and manage marine environments.

Our flagship platform, Hydrotwin, is rapidly expanding, with more than 300 monitoring systems operating worldwide. As our global fleet continues to grow, we are looking for a practical, hands-on Hydrotwin Fleet Technician to help deploy, operate, maintain and retrieve our monitoring systems. This role is ideal for someone who enjoys working both on the water and with technology. You'll be equally comfortable operating workboats, installing and servicing IoT monitoring equipment, troubleshooting technical issues, and representing blueOASIS professionally at customer sites.

Role Description

As a Hydrotwin Fleet Technician, you will play a key role in the global deployment and operation of Hydrotwin monitoring systems. You will be responsible for preparing, deploying, operating, maintaining and retrieving environmental monitoring equipment across coastal and offshore environments, ensuring the reliability and performance of our growing worldwide fleet.

This is a hands-on role combining marine operations, field engineering and customer-facing technical support. You will operate company vessels, install and commission new systems, diagnose and resolve technical issues, and support customers during deployments.

No two days are the same — you may be preparing equipment in the workshop one day and deploying monitoring systems offshore the next. Working closely with the engineering and product teams, you will help ensure Hydrotwin systems deliver high-quality environmental data while contributing to the continuous improvement of products and operational procedures.

Key Responsibilities

• Prepare, deploy, commission and validate Hydrotwin monitoring systems.
• Plan equipment, tools and logistics for field deployments.

• Support customer installations, demonstrations and technical training.
• Maintain accurate service records, deployment reports and technical documentation.
• Ensure compliance with health, safety and environmental procedures during all field activities.
• Maintain boats, trailers, tools and field equipment in a safe and operational condition.
• Provide field feedback to support the continuous improvement of Hydrotwin products and operations.
• Travel nationally and internationally to support customer deployments and maintenance activities.
