DSP Algorithms Engineer

We are seeking a Senior DSP Algorithms Engineer to join our team in Austin, TX. This role focuses on the system-level verification and stress testing of coherent optical DSP algorithms before silicon tape-out, ensuring robust performance under various optical conditions.

Responsibilities:

• Perform end-to-end system-level DSP verification for coherent optical systems.
• Design stress tests and corner cases to identify weaknesses pre-tape-out.
• Build and refine optical channel and impairment models.
• Apply deep DSP algorithm knowledge to expose weak points.
• Collaborate with DSP designers to define performance metrics and analyze failures.
• Develop and automate verification frameworks using MATLAB, Python, C/C++, or similar tools.
• Independently own verification strategy in a distributed team environment.

Qualifications:

• Deep expertise in coherent optical communications DSP with industry experience.
• Strong background in DSP algorithm development and system-level verification.
• Solid understanding of optical fiber channel behavior and physical impairments.
• Experience with coherent receiver architectures and signal processing chains.
• Extensive experience with DSP modeling/simulation tools.

Skills:

• Ability to independently define and execute complex verification strategies.
• Proficiency in MATLAB, Python, C/C++, or SystemC.
• Experience in RTL or hardware implementation awareness is a plus.
• Knowledge of AFE behavior and DSP interaction.
• Familiarity with fixed-point modeling and ASIC/DSP constraints.
