Position Summary
The Embedded Software Engineer joins a multidisciplinary module development team that includes hardware engineers, ASIC designers, optical experts, and manufacturing specialists. The firmware team owns the design, integration, verification, and automation of all software components required for coherent optical transceiver modules.
The engineer contributes across the full product lifecycle, from early feature definition to manufacturing readiness, while ensuring high code quality and system reliability.
Core Responsibility Areas
Embedded Software Development
The role focuses on independent development of DSP and ARM-based embedded software using a real-time operating system. This includes low drivers, control algorithms, higher-layer control logic, and management interfaces for complex multiprocessor systems.
Verification and Test Automation
The engineer implements and validates firmware features while clearly documenting test results. Automated tests are created and extended to strengthen the CI/CD pipeline and improve overall software quality.
Cross-Functional Collaboration
Close collaboration with hardware, ASIC, optics, factory, and system engineering teams is essential. The role also contributes to systems engineering activities by analyzing dependencies, defining implementation details, and supporting software interface documentation.
Systems and Automation Enablement
The position supports automation initiatives using tools such as Python and Jenkins. In addition, the engineer helps enhance internal test frameworks and continuous integration workflows.
Technical Domain Coverage
The role requires working knowledge across multiple functional domains, including device and link drivers, PLLs, optical control concepts, DSP configuration, high-speed ADC and DAC control, and protocols used in coherent optical communication systems.
Best Candidate Profile
Educational Background
Candidates hold a Master’s degree in electrical engineering, computer science, computer engineering, or a related discipline. A Bachelor’s degree, combined with at least 5 years of relevant experience, is also acceptable.
Language Requirements
Fluency in English is required for both written and spoken communication. German language skills at an intermediate level are preferred, with the expectation of progressing toward fluency.
Required Technical Skills
