Role Overview
This is a senior role with leadership and hands on responsibilities
At Coda Octopus, we develop world-leading underwater technologies for the offshore marine and defence markets. Our product portfolio includes pioneering augmented reality diving systems, real-time 3D volumetric imaging sonar, and advanced GNSS/Inertial Navigation Systems. Engineering-led, we design, manufacture, and support all of our products in-house, ensuring innovation, quality, and technical excellence throughout the product lifecycle.
We are now looking to appoint a Principal Engineer to join our Edinburgh-based team. This full-time, office-based role presents an exciting opportunity to provide technical leadership and make a significant impact on the development of next-generation underwater technologies.
Role Overview
The Principal Engineer will provide technical leadership for the development of advanced sonar systems, with particular focus on beamforming architectures, high-speed sensor electronics, FPGA/DSP processing, and embedded firmware implementation.
The role requires a strong background in hardware and firmware development for acoustic sensing systems and the ability to translate beamforming algorithms into efficient real-time implementations. The successful candidate will lead architectural decisions, mentor engineering teams, and drive innovation across the sonar signal processing chain from sensor array through to processed outputs.
Key Responsibilities
Technical Leadership
