Embedded Firmware Engineer

Position Overview

We are seeking an Embedded Firmware Engineer to write the highly deterministic, bulletproof code that powers our SIL-2 and ATEX Zone 0 gas detectors. 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

1. 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.
2. Diagnostic Implementation: Program the software diagnostics required by IEC 61508-3, including continuous RAM/ROM checks, watchdog timers, and fail-safe state triggers.
3. 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.
4. Code Compliance: Strictly adhere to MISRA C coding guidelines and participate in rigorous peer reviews and static/dynamic code analysis.
5. Documentation: Generate software architecture documentation and test reports required for the certification dossier (Material Construction File).



Required Qualifications & Experience

Experience: Minimum 5 years of embedded software engineering experience in a safety-critical environment (e.g., SIL-2/SIL-3 industrial, ISO 26262 automotive, or medical devices).

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

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

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