Senior Electronics Engineer

Essential qualifications/skills/experience

• A collaborative and supportive team player: prioritising team success above individual recognition, contributing actively to shared goals and supporting colleagues across disciplines.
• Broad hardware subsystem expertise: experienced in developing audio/acoustics, embedded controller, thermal, HMI, infrared, sensor and hardware/firmware interface.
• Practical, proactive mindset: comfortable taking initiative, working through ambiguity, and driving work forward in a fast-moving team without waiting to be told what to do.
• Clear, evidence-based communicator: explains complex technical topics in a structured, accessible and concise way to both technical and non-technical stakeholders, adapting style to the audience.
• Experience in accessibility, AAC or assistive technology domains: familiarity with user needs, environments and constraints common in AAC or related assistive technologies.
• Strong attention to detail in documentation: confident in producing clear design documentation, keeping BOMs accurate and version-controlled, using git effectively, and preparing for design and code reviews.
• Deep electronics design expertise: strong fundamentals in digital, analogue and power electronics, comfortable making architecture and component trade-offs to meet performance, reliability and cost goals.
• Circuit and PCB design capability: experienced in schematic capture, layout constraints, DFM/DFA principles and reviewing PCB layouts for signal integrity, EMC, reliability and manufacturability.
• Embedded firmware development (Zephyr RTOS): significant experience developing C/C++ firmware on Zephyr RTOS for modern microcontrollers (e.g. Nordic and STM32), including board bring-up, drivers and hardware abstraction layers.
• Test strategy, automation and CI mindset: hands-on experience designing testable firmware and hardware, building unit/component tests, and using CI or similar automation to catch regressions early.
• Standards and compliance literacy: working knowledge of safety and EMC standards such as IEC 60601-1 and IEC 60601-1-2, and how design, documentation and verification evidence support regulatory submissions.
• Risk management in engineering: practical experience with DFMEA / risk assessments, defining mitigations and controls, and generating verification and validation evidence in line with ISO 14971 or similar processes.
• Supplier and manufacturing collaboration: able to work constructively with manufacturing partners and key suppliers, resolving issues quickly and feeding their feedback into design decisions.

Useful Qualifications/skills/experience

• A passion for improving lives through assistive technology: genuinely motivated by empowering disabled people to communicate and live more independently.
• Commercial and product mindset: comfortable considering margin, cost of goods, ROI and market positioning when making technical decisions, and able to explain trade-offs in those terms.
• Broader compliance and regulatory expertise: familiarity with additional regulatory domains (e.g. FCC, CE, RoHS, REACH) and how they influence hardware and firmware design choices.
• Business and roadmap awareness: able to connect technical choices to product strategy, roadmap dependencies, and long-term platform decisions across Smartbox’s portfolio.
• Awareness of CPU/platform roadmaps (e.g. Intel and Arm): keeps up to date with key developments in Intel and Arm-based platforms, and can factor future availability, performance and lifecycle into architecture choices.
• PCB manufacturing and supply-chain awareness: understanding of PCB fabrication and assembly processes, test strategies and common failure modes, and how global supply constraints affect component and design choices.
