Photonics & DSP Engineer (Coherent Systems) in Konrad Enterprises

We are developing a system for precision analysis of backscatter in fiber. We need an engineer capable of converting phase shifts in a high-frequency optical signal into structured data.

Sprint project: 8 weeks.

Stack and tasks:

• Hardware: Construction of an interferometric circuit based on Narrow Linewidth Laser (1550 nm) and AOM. Optimization of "radiation - detection".

• Data Acquisition: Work with 100+ MS/s data streams (FPGA/DAQ). Synchronization of the pulse modulator with the data collection path.

• DSP: Phase extraction, noise removal and digital demodulation.

• Analytics: Development of event classification logic based on frequency signatures (spectral analysis, threshold logic).

Requirements for expertise:

• Optics: Deep understanding of coherence, Rayleigh scattering and phase modulation methods. Experience with SMF-28 (FC/APC) and optical circulators.

• Signal Processing: Professional Python (NumPy, SciPy). Confident work with FFT, digital filtering and non-stationary signals.

• Tools: Experience with high-end measuring equipment (fast oscilloscopes, spectrum analyzers).

Offer:

• Work with premium iron (Thorlabs, Aerodiode).

• High dynamics: the path from an idea to a working prototype in 60 days.

• Decent payment for the result and full engineering autonomy.
