You will be responsible for separating life-safety gas detection loops from secondary functions like cloud connectivity, ensuring that our devices fail safely and operate with absolute reliability under IEC 61508 standards.

Core Responsibilities :

Core Safety Loops :

- Write the embedded C/C++ firmware that manages primary gas monitoring, alarm triggers, and man-down motion alerts with zero latency or interruption.

Diagnostic Implementation :

- Program the software diagnostics required by IEC 61508-3, including continuous RAM/ROM checks, watchdog timers, and fail-safe state triggers.

Modular Integration :

- Seamlessly integrate drivers for the NevadaNano MPS sensors, custom FSTN displays, and 5G eSIM cloud alarm functions without compromising the primary safety loop.

Code Compliance :

- Strictly adhere to MISRA C coding guidelines and participate in rigorous peer reviews and static/dynamic code analysis.

Documentation :

- Generate software architecture documentation and test reports required for the certification dossier (Material Construction File).

Required Qualifications & Experience :

- 1. Experience : Minimum 7 years of embedded software engineering experience in a safety-critical environment (e.g., SIL-2/SIL-3 industrial, ISO 26262 automotive, or medical devices).

- 2. Programming Mastery : Expert-level proficiency in Embedded C/C++ and bare-metal programming.

- 3. RTOS Expertise : Deep experience implementing and managing Real-Time Operating Systems (RTOS) to handle concurrent critical and non-critical tasks.

- 4. Standards : Familiarity with IEC 61508-3 (Software Requirements) and strict adherence to MISRA C standards.
