Embedded Software Engineer

Deep Sea Electronics is a global leader in the design and manufacture of generator controllers, automatic transfer switch controllers, battery chargers, and vehicle and off-highway control systems. With over 200 employees across four continents, we supply our products to customers in more than 150 countries, both directly from our UK head office and through a well-established international distributor network.

Join the engineering team at Deep Sea Electronics Ltd, where you will design and deliver high-quality embedded software for industrial Control and Automation applications. The role focuses on real-time control, industrial communications and functional safety (IEC 61508/IEC 62061), creating robust solutions for environments such as power generation, manufacturing, utilities and process industries. You will contribute across the product lifecycle - from requirements and architecture through implementation, verification, certification and field support.

• Expert in C/C++ for microcontroller development
• Functional Safety: IEC 61508 (and/or IEC 62061); safety concepts (SIL, SFF, PFH), safety planning and verification
• Principles of Industrial Automation products: control theory basics (PID), sensors/actuators, transducers and signal conditioning
• Electrical principles
• Familiar with stage gated / agile development approaches
• Comfortable collaborating closely with electronics engineers on embedded systems
• Working to a high-quality standards
• Excellent team player with problem-solving and trouble-shooting capabilities
• Experience defining a task breakdown for a give piece of work and provide estimates
• Ability to translate requirements into a technical product specification
• Experience in working in a high-pace environment
• Enthusiastic and optimistic
• Development with Real Time Operating Systems
• Development of unit tested C code, using Jenkins or similar
• Source code build tools, bug tracker tools, source code repositories, etc
• BEng or above in Electrical and Electronic Engineering

• Design and implement C/C++ software for embedded devices (bare-metal and RTOS) used in industrial control systems
• Develop real‑time control algorithms (e.g., PID, state-based control) for sensors, actuators, and power systems
• Produce work break down structures and define work packages for execution in JIRA tasks and integration into high level plans
• Integrate with industrial control equipment and software, including PLCs, HMIs and SCADA systems
• Implement and validate industrial communication protocols:
  Modbus (RTU/TCP), CAN/CANopen/J1939, Ethernet/IP, PROFINET, OPC UA, RS‑232/RS‑485
• Apply functional safety practices in line with IEC 61508/IEC 62061, including SIL determination, Safety Requirements Specifications (SRS), HARA/FTA/FMEA, and verification evidence
• Contribute to software quality by the use of coding standards (e.g., MISRA C/C++) and static analysis tools, performing code reviews and developing unit/integration tests
• Create test plans and perform functional product verification and validation activities
• Author and maintain engineering documentation: architecture, design descriptions, interface control documents, test plans, and safety lifecycle artefacts
• Collaborate closely with electronics, test & approvals, cybersecurity and product management to deliver cohesive solutions
• Support system integration, commissioning and troubleshooting at parent company and customer sites (UK and international travel required)
• Contribute to continuous improvement of processes, tool chains, CI/CD and development workflows (e.g., Git, Jira, code review)
• Mentor less‑experienced engineers; share knowledge through design reviews, brown‑bags and documentation
• Participate in sustaining activities for existing products,…
