The role:

We're seeking a skilled Software Engineer to join our team developing advanced autonomy and control systems for autonomous marine vessels. You'll play a key role in designing robust, high-performance software, from real-time autonomy modules and communication systems to simulation tools for testing and validation. If you enjoy solving complex problems, building intelligent systems, and seeing your software operate in challenging real-world environments, we’d love to have you onboard.

Responsibilities include:

• Software design and development in line with system requirements, with a focus on simulation, autonomy, and communication.
• Developing and maintaining simulation environments for testing autonomous behaviours and system integration.
• Implementing robust, scalable autonomy features including mission planning, perception integration, and decision-making logic.
• Testing and validation of software, including unit testing, simulation-based testing, bench testing, and sea trials.
• Production of comprehensive software documentation.
• Conducting peer reviews to ensure designs are reliable, modular, and maintainable.
• Collaborating closely with the software and engineering teams to ensure timely delivery of high-quality software and documentation.

Essential skills and experience:

• Degree-level qualification in Computer Science, Mechatronics, Robotics, or similar, or equivalent industry experience.
• Software development experience in modern C++ (14 or newer).
• Solid understanding of object-oriented programming and software architecture principles.

Desirable skills and experience (any would be desirable)

• Experience with ROS or ROS2.
• Experience with simulation tools (e.g., Gazebo, Unity, Webots, or custom simulation frameworks).
• Familiarity with autonomous systems and robotics software stacks.
• Experience with real-time systems or control systems.
• Understanding of sensor fusion, path planning, or state estimation.
• Experience with Qt/QML or other UI frameworks (for internal tools or visual debugging).
• Experience with marine or mobile robotics projects.

Note: Due to the nature of work undertaken at SubSea Craft, the selected candidate must be capable of meeting the security requirements of the position, which would include as a minimum existing right to live and work in the UK, Baseline Personnel Security Standard (BPSS), with UK National security clearance required for certain roles.*
