What the job involves
- Contract: Immediate start - 12 week contract
- We're looking for four Embedded C++ Developers to join an in-house backend engineering team working on a highly regulated, safety-critical medical technology product
- You'll own a self-contained area of the application, taking work from initial design through to merged, tested and documented code. Depending on your experience and the team's needs, this could include areas such as alarms, patient data persistence, device supervision and start-up, session management or service functionality
- You'll work closely with the Software Architect and engineers responsible for surrounding components, while taking ownership of delivery within your area
- This role is well suited to an experienced Embedded C++ Engineer who has worked on Linux-based safety-critical, mission-critical or highly regulated products and is comfortable working with formal quality processes, static analysis, code coverage and rigorous testing requirements
- Your work could span a number of areas of the embedded application, including:
- Alarms
- Developing technical alarm conditions based on hardware and operating system telemetry
- Working with signals including battery, temperature, clock, power faults and telemetry quality
- Implementing patient sensor, signal quality and external monitoring alarms
- Working with hardware alarm interfaces including mute functionality, alarm-level verification and alarm telemetry
- Building robust fault handling and recovery mechanisms
- Start-Up, Self-Test & Supervision
- Developing power-on checks covering logging, hardware compatibility, GPU checks and system self-tests
- Implementing fail-safe states and fault management
- Integrating watchdog and system supervision mechanisms
- Supporting interrupted-session detection and recovery
- Developing logging, audit logging and log rotation functionality
- Working with OS telemetry including power button and storage health monitoring
- Patient Data Persistence & Presentation
- Developing storage interfaces supporting atomic and checksummed writes
- Managing reading, deletion and session listing across fixed storage partitions
- Building patient-data packaging, queueing, flushing, retention and retrieval functionality
- Supporting data back-fill and historic data presentation
- Developing versioned interfaces between backend data and the GUI
- Session Lifecycle, Power-Down & Service
- Managing patient sensor and session lifecycles
- Supporting session metadata, recovery and graceful shutdown
- Developing power-button handling and controlled power-down functionality
- Supporting USB data export functionality
- Working with service tools and device service handlers
- Supporting software updates, confirmation and rollback
- Implementing log extraction and audit logging
- You'll be working with technologies and practices including:
- C++17
- Embedded Linux
- NVIDIA Jetson / aarch64
- Yocto
- CMake & Conan
- Docker
- GoogleTest
- FlatBuffers
- Boost.Asio
- D-Bus
- Systemd / sd_notify
- Unix-domain sockets
- NVMe storage
- SonarQube
- MISRA C++ 2023
- Doxygen
- CI/CD and target-hardware testing

Our take
As the need for digital transformation continues to grow, many organisations find themselves lacking the skills to keep up. AND Digital has stepped in to help bridge this gap, with a clear mission to close the world's digital skills shortage. Rather than simply delivering digital solutions, they focus on helping businesses understand how to work digitally, so they can continue to grow and adapt long after a project is finished.
The company is standing out from the crowd too, by working alongside their clients instead of working for them. Combining their own people with client teams into one collaborative unit, they identify challenges, build digital products, and share skills throughout the process, so clients can take full ownership of their apps, websites, and future digital work.
Unsurprisingly, this approach has had a strong impact and continues to drive AND Digital's growth. With cross-functional teams across the UK, the Netherlands, and the US East Coast, the company scales based on demand. And their city-based 'Club' model blends local, personalised service with the strength of a global organisation, putting AND Digital in a strong position for the future.
