About the role

Wireless Control Systems Engineer responsible for end-to-end lifecycle of cellular modem systems (6G/5G/4G), from feature design through silicon bring-up and productization, with cross-functional collaboration across SoC, PHY, FW, and L1 SW to optimize performance and power across the wireless stack.

Responsibilities

  • Define & architect system-level features and requirements for next-generation cellular modems, with a focus on 6G evolution and advanced PHY/L1 capabilities.
  • Own the E2E system view — connect 3GPP standard requirements, algorithm design trade-offs, HW/FW architecture constraints, and product-level targets into cohesive, leading-edge control solutions.
  • Design Control algorithms (Traditional or AI/ML based) for the physical layer, across layers and L1/RF control to optimize performance/power.
  • Construct interfaces and Message flows for wireless features across layers.
  • Model & simulate algorithms in floating-point and fixed-point using MATLAB, C/C++, and/or Python, and validate, through link-level simulation or correlating with data collected from field and real deployments.
  • Optimize for user experience by driving performance and power efficiency improvements across the wireless stack — translating system-level insights into tangible gains in throughput, latency, battery life, and connectivity reliability based on real world deployments.

Qualifications

  • BS in Electrical Engineering, Computer Engineering, or a related field, with 10+ years of relevant industry experience in Layer 1 control design.
  • Strong knowledge of cellular communication standards: 6G (emerging), 5G NR, 4G LTE — particularly RAN1 3GPP.
  • Deep expertise in communication system theory and signal processing: LDPC, Polar, and Turbo coding; signal estimation and detection; AGC; RF impairment estimation and correction; channel estimation; OFDM; MIMO detection; waveform generation and up-sampling.
  • Proficiency in MATLAB, C/C++, and/or Python for algorithm development, fixed/floating-point modeling, and link-level simulation.
  • Experience leveraging Generative AI and LLM-based tools to accelerate engineering workflows — e.g., algorithm prototyping, code generation, simulation analysis, or technical documentation.
  • Experience in Layer-1 Control Design.
  • Experience in low-power algorithm design for power-constrained mobile platforms.
  • Experience in end-to-end timeline analysis for latency-critical PHY processing chains.
  • Hands-on silicon bring-up experience, including use of lab equipment: protocol testers, spectrum analyzers, signal generators, power meters.
  • Strong mathematical foundations: linear algebra, stochastic processes, detection & estimation theory.
  • Familiarity with 3GPP standardization processes, RAN2, RAN4 topics and emerging 6G study items (e.g., AI/ML for air interface, sub-THz bands, joint communication and sensing, reconfigurable intelligent surfaces).
  • Track record of published research or patents in wireless communications.
