Responsibilities

Perform end-to-end system-level DSP verification (Tx → Fiber → Rx) for coherent optical systems
Design aggressive stress tests, corner cases, and adversarial scenarios to uncover latent issues pre-tape-out
Build and refine optical channel and impairment models (dispersion, non-linearities, noise, laser effects)
Apply deep DSP algorithm knowledge to intentionally attack weak points
Partner with DSP designers to define performance metrics, analyze failures, and drive root-cause fixes
Develop and automate verification frameworks using MATLAB, Python, C/C++, or similar tools
Own verification strategy independently in a distributed team environment

Required

Deep expertise in coherent optical communications DSP with hands-on industry experience
Strong background in DSP algorithm development and system-level (pre-silicon) verification
Solid understanding of optical fiber channel behavior & physical impairments
Solid understanding of coherent receiver architectures & signal processing chains
Extensive experience with DSP modeling/simulation (MATLAB, Python, C/C++, SystemC)
Ability to independently define and execute complex verification strategies
EE or related degree (BS/MS/PhD); experience matters more than degree
Commercial/industrial experience (not purely academic)

Preferred

RTL or hardware implementation awareness
AFE behavior and DSP interaction
Fixed-point modeling, ASIC/DSP constraints
FEC (LDPC, RS, OFEC), mixed-signal effects (jitter, PLL/CDR)
