Job Overview
- ator specializing in programmable coherent DSP (Digital Signal Processing) solutions for cloud and AI infrastructure seeks a DSP Algorithms Engineer (System C Simulation) to join their Optical DSP team in Austin, Texas.
This role offers the opportunity to work at the intersection of optical systems, DSP algorithms, and System C simulation, directly contributing to the architecture and performance of coherent optical DSP ASICs.
Key Responsibilities
- Develop a comprehensive System C simulation platform that models full optical DSP systems, including TX/RX data paths, analog front-end, optical subassemblies, and firmware interaction.
- Translate MATLAB-based DSP models into efficient System C/C implementations.
- Design and integrate simulation frameworks for timing recovery, equalization, carrier recovery, FEC, DAC/ADC, and optical channel modeling.
- Model real-world effects such as fiber impairments, noise, jitter, and OSNR to evaluate DSP performance (BER, EVM, sensitivity).
- Collaborate closely with DSP algorithm developers, ASIC design, and verification teams to ensure seamless architecture validation.
- Build regression test environments and ensure robust verification of full DSP chains.
- Document simulation architectures, APIs, and development methodologies for team-wide usage.
- Support architecture trade-off studies and provide insights that influence DSP ASIC design decisions.
- Master’s degree (MSc) in Electrical Engineering, Computer Engineering, or a related field.
- Minimum 10 years of experience in DSP design and modeling for communications, optical, or related systems.
- Strong proficiency in System C / C , with proven experience building modular simulation environments.
- Hands-on experience with MATLAB DSP prototyping and translation into System C.
- Solid understanding of digital communication systems:
- Modulation
- Equalization
- Coding
- Carrier & timing recovery
- Familiarity with coherent optical communications and fixed-point modeling.
- Experience in DSP ASIC design flow and cross-functional collaboration with hardware/firmware teams.
- Excellent analytical, debugging, and teamwork skills.
- Job stability and continuity — no frequent job changes or breaks.
- Experience with verification methodologies such as UVM/SystemVerilog or HW/SW co-simulation.
- Familiarity with HDLs (VHDL/Verilog) or HLS (High-Level Synthesis) design flows.
- Exposure to FEC algorithms (LDPC, RS, OFEC) and their integration in DSP systems.
- Understanding of PLL/CDR, jitter modeling, and mixed-signal impairments in high-speed systems.
- Experience in ASIC system-level performance validation or optical link modeling.
Salary : $160,000 - $180,000
