Job summary

AND Digital is seeking four Embedded C++ Developers for an in-house backend engineering team working on a highly regulated medical technology product in London. You will own a self-contained area of the application and drive design through to tested, documented code.

The role emphasizes strict QA, diagnostics and robust fault management in a Linux-based environment with experience in safety-critical software and formal engineering processes.

Qualifications

• Strong experience developing modern C++17 applications on embedded Linux.
• Strong understanding of RAII, fixed-width types, std::atomic, multithreading and lock-free or bounded queues.
• Experience developing software where deterministic behaviour and reliability are critical.
• Experience with allocation-free or low-allocation runtime environments, including pre-allocated memory and fixed-capacity containers.

• Experience working on safety-critical, mission-critical or highly regulated software.

Responsibilities

• Own a self-contained area of the application from design through tested, documented code.
• Areas may include alarms, patient data persistence, device supervision and startup functionality.
• Collaborate with Software Architect and other engineers to deliver within your area.
