<p><span>EFFECT Photonics is a technology scale-up founded in Eindhoven. In our office in the Netherlands, we focus on developing advanced laser solutions for optical communication systems, built around integrated photonics chips on the indium phosphide platform.</span></p><br><p>We are seeking to expand our team with a highly skilled <strong>Firmware Development Engineer</strong> with experience in driving embedded software projects from architecture definition to product release. Ideal candidate should have electrical engineering, telecommunication or computer science background with exposure to real-time control, experienced with mixed signal microcontrollers also when paired with external analog front-ends and preferably used in telecom equipment. The role involves collaboration with a broader team on cross-functional topics, e.g., electronics design, optical-subassembly (OSA) behaviour and integration into the third-party host systems.</p><p><br></p><p>At EFFECT Photonics we value ownership. Our new colleague will be given the autonomy to take charge of their projects and drive innovative solutions. We work in a multi-disciplinary environment, where the new colleague will be the owner of the firmware behaviour and can expand their knowledge in areas such as electronics, physics, and telecommunication. </p> <ul> <li>Master’s degree in electrical engineering, telecommunication, or similar; to be able to judge the impact of firmware behaviour on the rest of the assembly.</li> <li>Minimum 8 years of relevant experience, primarily firmware development in C, C++ for mixed signal microcontrollers, preferably ARM-based. Current implementation is bare metal, but RTOS experience is a plus.</li> <li>Demonstrated ability to own firmware development process, write clean code, understand, and review existing code.</li> <li>Extensive experience with MCU peripheral control: Timer, SPI, I2C, UART, ADC, DAC, DMA, Flash controller, etc., including advanced operation modes where peripherals are DMA scheduled.</li> <li>Experience interfacing with external analogue front-ends, memories, and power converters.</li> <li>Proficient in handling shared resources, including critical sections to prevent shared resource usage in interrupts.</li> <li>Experience in state machine implementation with extensive self-testing.</li> <li>Good knowledge of Git and the Atlassian tool suite (Jira, Bitbucket, Confluence).</li> <li>Experienced with Doxygen or comparable software documentation tools.</li> <li>Sufficient Python mastery for test and deployment automation, and basic firmware characterization scripting. Remote instrument control is a plus.</li> <li>Basic knowledge of control theory, e.g., feedback loops, PID controllers, and basic parameter calibration. Advanced control theory knowledge is a plus.</li> <li>Experience in simple linear filter design and implementation in firmware.</li> <li>Sufficient electronics knowledge to correctly implement firmware drivers for MCU electrical interfaces and contribute to review from firmware development perspective.</li> <li>Proficient in using measurement equipment to verify and debug communication and A/D interfaces.</li> <li>Experience with firmware development for optical communication modules or subassemblies is a plus.</li> </ul> <ul> <li>Firmware development and testing for OSAs, and test infrastructure.</li> <li>Develop test cases and ensure high firmware reliability in all corner cases. </li> <li>Verify firmware behaviour on products and prototypes, including debugging electrical interfaces.</li> <li>Quickly develop into a go-to person on firmware behaviour for the optical sub-assembly.</li> <li>Contribute to firmware architecture development and eventually own it.</li> <li>Clearly document firmware behaviour and development process.</li> <li>Ensure timely firmware releases with clear communication to the stakeholders.</li> <li>Collect infeed from the rest of the organization for further firmware development.</li> <li>Review OSA behaviour specifications and electronics designs from firmware development perspective.</li> </ul>
