About this role
Job title: Senior DSP/OFDM Engineer Lead
About the Role This role focuses on design, development, and optimization of OFDM-based digital and analog radio systems. It combines hands-on DSP algorithm development with system-level debugging, performance optimization, and long-term technical leadership, including building and leading a future DSP engineering team in India.
What You'll Do
- Design, implement, and optimize DSP algorithms for OFDM-based modems, including modulation/demodulation, synchronization, channel estimation/equalization, FFT/IFFT processing, and error detection/correction, with emphasis on robustness under RF impairments.
- Translate system requirements into production-quality DSP software; debug across DSP, firmware, RF, and hardware boundaries; analyze lab and field data to identify root causes of performance, stability, and interoperability issues; support bring-up, validation, and long-term maintenance.
- Drive code-level optimization for MIPS efficiency and memory footprint on embedded targets; optimize for CPU throughput and real-time constraints; cache efficiency and memory access patterns; fixed-point arithmetic and reduced precision implementations; balance performance, memory usage, power consumption, and algorithm accuracy; guide architectural trade-offs.
- Lead architecture decisions for OFDM-based modem systems; evaluate system-level trade-offs involving bandwidth, latency, spectral efficiency, and robustness; ensure algorithm designs scale efficiently across multiple platform variants.
- Act as technical authority for DSP and communications; establish and technically lead a DSP engineering team in India, including mentoring engineers, defining coding standards and development workflows, providing technical oversight and design reviews, and collaborating with RF, hardware, firmware, and systems engineering teams.
What We're Looking For
- M.S. or Ph.D. in Electrical Engineering, Signal Processing, Communications, or related field.
- 10+ years of experience in DSP and communication system development.
- Deep expertise in OFDM-based modem design, including synchronization, channel estimation, equalization, and decoding.
- Strong background in digital and analog communication theory.
- Demonstrated experience in code optimization for MIPS and memory-constrained embedded systems.
- Proficiency in relevant DSP and embedded systems concepts.
