An Australian R&D and manufacturing company is looking for a Senior Embedded Software Engineer to design and develop firmware for cutting-edge monitoring and IoT devices. This is a hands-on role working with STM32 and NXP microcontrollers to deliver highly reliable systems deployed in the field.

You’ll take ownership of embedded software architecture, apply modern C++ (including object-oriented design and template programming), and lead testing and validation to ensure products perform in real-world conditions. This role also offers a pathway into technical leadership within 8–12 months.

This is a full-time, permanent position based in Sydney, with hybrid work flexibility after an initial in-office period. For interstate candidates, relocation is required.

Key Responsibilities

• Design and implement embedded software in modern C++ (C++11/14/17) for resource-constrained systems.
• Develop firmware architecture for STM32 and NXP microcontrollers (ARM Cortex-M series).
• Work closely with hardware engineers to review schematics, debug board bring-up and define hardware requirements for future revisions.
• Integrate peripherals such as UART, SPI, I2C, ADC/DAC, and low-power wireless modules (LoRa, cellular).
• Lead end-to-end testing and validation, ensuring firmware performs reliably in harsh, remote environments.
• Write detailed documentation for architecture, code design, and testing procedures.
• Support the adoption of CI/CD practices in embedded development workflows.
• Provide technical guidance and mentoring as the team grows.

Essential Requirements

• Strong proficiency in modern C++ (object-oriented programming, templates, and best practices for embedded systems).
• Hands-on experience with STM32 and/or NXP (ARM Cortex-M) microcontrollers.
• Solid understanding of electronics fundamentals, with the ability to interpret schematics and collaborate on hardware debugging.
• Proficiency in Python for scripting, automation, or test frameworks.
• Familiarity with real-time constraints, memory management, and low-power design.
• Excellent communication skills and the ability to document complex systems clearly.
• Australian Citizenship or Permanent Residency (visa sponsorship is not available).

Desirable Skills but not strictly required

• Experience with IoT systems or telemetry in remote environments.
• Knowledge of wireless protocols such as LoRaWAN, LTE-M, NB-IoT.
• Familiarity with bootloaders, secure OTA updates, and field upgrade strategies.
• Exposure to CI/CD pipelines for embedded development.
• Knowledge of Java or JavaScript for device-cloud integration.
