Embedded Software Developer (Optical Control)
Job Summary
We are looking for an Embedded Software Engineer to develop the software that directly controls and stabilizes Layer 0 optical components in advanced DWDM systems. You will build real-time and near-real-time software responsible for managing lasers optical power and signal behavior ensuring high-performance and reliable operation of optical transport equipment. This is a hands-on role at the intersection of embedded systems control logic and photonic hardware.
What youll do
- Design and implement embedded software for Layer 0 optical control systems
- Develop and optimize control loops for optical power wavelength stabilization and signal quality
- Interface directly with hardware components such as lasers VOAs amplifiers and sensors
- Implement real-time or near-real-time feedback systems for optical calibration and control
- Develop low-level drivers and hardware abstraction layers (I2C SPI etc.)
- Collaborate with system architects to translate optical behavior into software functionality
- Contribute to fault detection protection and restoration mechanisms in optical networks
- Expose system functionality via management interfaces (e.g. REST APIs telemetry systems)
- Debug complex issues across hardware firmware and software layers
- Participate in system bring-up integration and performance tuning
- Optimize software for performance reliability and scalability in carrier-grade environments
- Write clean maintainable and well-documented code
What youll need to get the job done
- 5 years of relevant experience
- Strong programming experience in C/C and/or Rust
- Experience with embedded Linux or low-level systems programming
- Hands-on experience interfacing with hardware and developing drivers
- Understanding of control systems or feedback loop implementation
- Experience with multi-threaded or real-time software systems
- Familiarity with debugging across software and hardware boundaries
- Exposure to telecom or networking systems (optical experience is a strong plus)
- Experience with version control (Git) and modern development workflows
- Strong problem-solving skills and ability to work in cross-functional teams
What will make us REALLY love you
- Experience working on DWDM ROADM or optical transport systems
- Background in control theory signal processing or physics-based systems
- Experience implementing Layer 0 protection and restoration mechanisms
- Familiarity with network management models (YANG OpenConfig NETCONF)
