Embedded SW Engineer

Job Description

The Optical Networks System & Automation group develops pluggable transceiver modules for coherent optical fiber transmission. The applications include Communication Service Provider (CSP) network node as well as intra and inter data center connections. Our team is part of a module development team comprising hardware development, full custom ASIC design, experts for optical components and firmware (FW) development. We are closely working together with all functions required from the product definition to manufacturing.

We are expanding our FW team and looking for highly motivated engineers to join us in developing the next generations of transmission systems. The FW team is responsible for designing, integrating, and verifying all software parts required for an optical coherent transceiver module. This includes software targeting a complex multi-processor system embedded in custom hardware, low level driver software, algorithms controlling optical components and the digital signal processor, higher layer control software and the management interface application.

How you will contribute And what you will learn

How you will contribute and what you will learn:

• Independent development of DSP / ARM embedded software using a Real Time Operating System (RTOS)
• Implement and validate the code, document the test results including creation of automated test
• Work in interdisciplinary teams (HW, ASIC, optics, factory)
• Cover systems engineering aspects and documentation (collect and understand features and dependencies / impact; work out feature implementation details; define SW UG; interface to SW)
• A selection of topics includes
  • Develop AI solutions for our customers and internal AI solutions
  • Provide automation solutions (e.g. Jenkins)
  • Design optimized control concepts for optical devices partially with non-linear characteristics including simulation and stability analysis
  • Expert for DSP in the field of coherent optical communication
