DSP Algorithm Engineer; System Level Testing Algorithm

DSP Algorithm Engineer (System Level Testing)

Austin, Texas

We are seeking a highly skilled Algorithm Engineer to develop, execute, and automate system-level tests for advanced coherent optical DSP
. In this role, you will work at the intersection of signal processing and optical communications to ensure the performance, robustness, and readiness of cutting‑edge coherent DSP.

Key Responsibilities

• Design, implement, and maintain system-level test frameworks to validate and stress coherent DSP algorithms across the full signal chain.
• Develop automated end-to-end test environments including channel models, impairments, hardware‑in‑the‑loop elements, and performance analytics.
• Create novel stress tests, corner‑case scenarios, and fault‑injection methodologies to uncover algorithmic weaknesses.
• Work closely with algorithm developers to define test requirements, acceptance criteria, and performance metrics.
• Analyze test results, identify root causes of performance degradation, and drive corrective actions.
• Generate detailed documentation covering test design, simulation assumptions, and system‑level performance trends.

Requirements

• MSc in Electrical Engineering, Computer Engineering, or related field.
• Experience with MATLAB DSP prototyping and translation C/Phyton.
• 10+ years of experience in DSP design and modelling
  , preferably for communications or optical systems.
• Strong proficiency in MATLAB / C++, with hands‑on experience building modular simulation frameworks.
• Solid understanding of digital communication systems (modulation, coding, equalization, carrier and timing recovery).
• Knowledge of coherent optical communications
  .
• Excellent problem‑solving and teamwork skills.

Nice to Have

• Familiarity with fixed‑point modelling and ASIC/DSP design flow
  .
• Exposure to FEC codes (LDPC, RS, OFEC) and their integration into DSP systems.
• Understanding of jitter, PLL/CDR modelling
  , and mixed‑signal impairments in simulations.

Why Join Us?

• Be at the forefront of next‑gen optical communication systems (800G, 1.6T, and beyond).
• Collaborate with a multidisciplinary team of DSP, optics, and hardware experts.
• Influence architecture decisions by providing critical simulation insights.
• Opportunity for career growth in both DSP algorithm design and system architecture
