Senior Electronics Engineer in London

Join us in making sure no one is left without a voice. At Smartbox, our assistive technology empowers people with disabilities who experience speech difficulties to express themselves, connect with others, and live more independent lives. We're proud to be a global leader in augmentative and alternative communication (AAC), supporting people across the UK, US, Europe, and beyond.

The opportunity: You will join a collaborative and high-performing hardware team, working together to deliver meaningful outcomes. We value shared goals, thoughtful problem-solving, and creating technology that makes a real difference. Based in the heart of Bristol city centre, just off Park Street, our location connects us to a well-established and growing technology community. You will lead the electronics design and system architecture of our medical-grade tablet computers, taking responsibility for electronic subsystems and overall hardware architecture. In this hands-on leadership role, you will design circuits, select components, build prototypes, and deliver projects, while supporting the team with technical direction and strong engineering practices.

What you'll be doing: You'll bring technical leadership and practical expertise across the product lifecycle, including:

• Leading the design, development and delivery of complex electronic systems.
• Defining system architecture and subsystem strategies across hardware and firmware.
• Designing circuits, reviewing PCB layouts, and building and testing prototypes.
• Contributing to firmware development and engineering best practices.
• Driving verification, validation and regulatory compliance (including medical standards).
• Collaborating with teams across hardware, production, quality, and repairs.
• Building strong relationships with suppliers and manufacturing partners.
• Mentoring and supporting engineers, helping to grow a collaborative and high-performing team.

A full list of duties can be found on our website, under the careers tab.

Why this role is unique: This isn't a typical electronics role; you'll be working at the intersection of:

• Medical-grade hardware and embedded systems.
• Assistive technology and accessibility.
• Highly integrated, multi-disciplinary products.

We're solving complex, real-world challenges where reliability, usability and performance truly matter, and where your decisions directly impact people's daily lives.

What we're looking for: We're looking for a rare combination of deep technical expertise, curiosity, and purpose-driven thinking.

Essential experience:

• Strong background in electronics design (analogue, digital, and power).
• Experience owning or contributing to complex hardware architectures and subsystems.
• Hands-on expertise in circuit design and PCB development.
• Embedded firmware experience (C/C++, ideally with RTOS such as Zephyr).
• Experience working in regulated environments (e.g. medical, safety-critical).
• Knowledge of EMC, safety standards (e.g. IEC 60601) and engineering risk management.
• Proven ability to balance technical quality, cost and manufacturability.
• Strong communication skills: able to explain complex concepts clearly.
• A collaborative mindset with a passion for mentoring and teamwork.

Some areas we often work with include:

• Assistive technology, AAC or accessibility-focused products.
• Product strategy, supply chains, and long-term platform thinking.
• Working closely with manufacturers and external suppliers.
