Job description

We're seeking a talented Firmware Engineer to design and implement robust, high-efficiency firmware for our next-generation opto-electronic devices. You will work at the intersection of hardware and software, writing low-level code that interfaces directly with sensors, lasers, detectors, and custom electronic platforms.

Key Responsibilities

• Develop and maintain firmware for embedded systems in C / C++.
• Design and implement drivers for peripherals and optical components (SPI, I2C, UART, USB, GPIO).
• Collaborate with hardware teams during schematic reviews, bring-up, and testing.
• Work with optical subsystems such as photodiodes, laser control modules, and high-speed ADCs.
• Participate in system testing, debugging, and optimisation.
• Document firmware architecture, interfaces, and test procedures.

Required Skills & Experience

• Degree in Electronic Engineering, Computer Engineering, or a related field.
• Minimum 3 years of firmware development experience in embedded environments.
• Strong skills in embedded C / C++ programming.
• Experience with microcontroller platforms (STM32, NXP, TI, etc.).
• Ability to debug hardware-software interactions using lab tools (oscilloscope, logic analyzer, JTAG).
• Understanding of real-time constraints and memory-constrained systems.

Bonus Points for Experience With :

• Optical or photonic systems (lasers, photodiodes, modulators).
• Embedded Linux or RTOS environments.
• Scripting (Python, Bash) for automation or testing.
• Signal processing or digital filtering techniques.
• Regulatory compliance (EMC, CE, safety standards).

What We Offer

• Work with cutting-edge technology in a fast-paced, impact-driven team.
• Competitive salary, flexible hours, and career growth opportunities.
• Exposure to global projects with local impact.
• A collaborative culture where your engineering voice matters.
