Job description

Senior Electronics Hardware Engineer

Our client develops and manufactures subsea systems and products used across Energy, Ocean Science, Offshore and Defence sectors. Their products are used for communication, navigation, sensing and positioning.

You’ll provide senior electronic design expertise for advanced subsea instrumentation, including optical modem technology and seismic recorder electronics. A key part of the role is taking ownership of externally developed designs and source code, and making sure they become fully supportable, documented and production-ready in-house.

Key responsibilities

• Develop, review and modify electronics hardware, embedded firmware and FPGA designs
• Take ownership of inherited designs, source code, interfaces and test methods
• Work on low-power, low-noise, reliable subsea electronics and electro-optical interfaces
• Support optical link performance testing and optimisation
• Use embedded C, FPGA and Python for development, diagnosis and test automation
• Help bring products to production readiness, including test fixtures and automated test
• Provide senior input on design reviews, integration, verification and fault finding
• Produce clear documentation, and work with internal teams and external partners to close design knowledge gaps

Skills and experience

• Expert: electronics design, low-power design, embedded C/C++, FPGA, fault finding, documentation
• Competent: Altium PCB design, ADCs and precision acquisition, clocks and timing, communication protocols (SPI, I²C, UART, Ethernet, RS-485/232), EMC (EN60945), production support
• Basic: electro-optical interfaces

Qualifications

• Essential: 2:1 or above in a relevant engineering degree
• Desirable: Master's or PhD in a relevant area (electronics, embedded systems, FPGA, photonics, instrumentation)

They are offering an excellent salary and benefits package, along with the opportunity to work on cutting edge subsea product development.
