Job Description

Principal Software Engineer

We are seeking an experienced Principal Software Engineer to lead the development of advanced scientific instrumentation within a multidisciplinary R&D environment.

You will translate physical principles and user requirements into robust, production-ready systems spanning firmware, hardware integration, and high-level applications.

Key Responsibilities

  * Lead architecture across embedded firmware (C/C++) and application software (C#/.NET).

  * Provide technical leadership and mentorship to Software, Firmware, and Electronics Engineers.

  * Develop physics-based algorithms for signal processing, instrument control, and data interpretation.

  * Integrate software with complex opto-electronic and hardware systems.

  * Define development standards, drive Agile practices, and implement CI/CD pipelines.

  * Contribute to next-generation product innovation in thermal analysis and materials characterisation.

Requirements

  * Honours degree in Physics, Mathematics, or Engineering (with strong Physics basis).

  * 10+ years’ commercial software development experience.

  * Expert in C#/.NET; strong C/C++ for embedded systems.

  * Experience with hardware communication protocols (I2C, SPI, USB, Ethernet).

  * Proven leadership within multidisciplinary engineering teams.

  * Background in scientific instrumentation, industrial automation, or similar hardware-integrated environments.

Desirable

  * Signal processing (FFT, digital filtering) or image processing

  * MATLAB or Python for prototyping

  * Cloud/IoT connectivity (Azure/AWS)

  * Experience leading multi-discipline teams

This is a high-impact role for a technically strong leader with a “first principles” mindset who can bridge physics and software to deliver innovative, market-leading products.
