Contract C ++ Developer

Overview

In this contract role, you will contribute as an Embedded C++ Engineer in an in-house backend team for a regulated medical technology product. You will own a self-contained area from design to tested, documented code, influencing alarms, data persistence, and service functionality. Collaboration with the Software Architect and peers will shape delivery and quality in a safety-critical environment. The role emphasizes deterministic behavior, rigorous testing, and formal quality processes, offering meaningful impact in medical tech.

Responsibilities

• Own a software area from design through delivery and documentation
• Develop alarms, data persistence, startup supervision, and service functionality for a medical device
• Implement fault handling, watchdog integration, and system supervision
• Develop logging, auditing, and log rotation; support data back-fill and historic data presentation
• Ensure power management, graceful shutdown, and software updates with rollback
• Work with Linux-based safety-critical systems and formal engineering processes

Key requirements

• Strong C++17 experience on embedded Linux
• RAII, std::atomic, multithreading and either lock-free or bounded queues
• Deterministic, reliable software in safety-critical contexts
• Allocation-free or low-allocation runtimes with pre-allocated memory
• Experience with hexagonal architecture, interfaces, and dependency injection
• Linux systems integration (services, watchdog, fault management)
• IPC and serialization (FlatBuffers, Unix-domain sockets, named pipes)
• CMake, automated testing, CI/CD; cross-compilation for aarch64
• Unit testing, code coverage, quality gates; safe software development practices
• Experience with safety-critical, mission-critical, or highly regulated software

• Structured, quality-focused mindset
• Comfortable working with formal quality processes
• Collaborative team player and effective communicator
• FlatBuffers
• Unix-domain sockets
• CMake
