Requisition ID: 77664

Job Description:

Description

Design, development, and optimization of advanced OFDM-based digital and analog radio communication systems. This role combines deep hands-on algorithm development with system-level debugging, performance optimization, and long-term technical leadership.

The position also includes responsibility for building and leading a future DSP engineering team in India, defining scalable development practices, and ensuring efficient, high-performance implementations suitable for embedded and real-time platforms.

Responsibilities

DSP Algorithm Development

Design, implement, and optimize DSP algorithms for OFDM-based modems.
Develop algorithms for:

Modulation and demodulation
Time and frequency synchronization
Channel estimation and equalization
FFT/IFFT processing
Error detection and correction

Improve algorithm robustness and performance under real-world RF impairments.

System Design, Debugging & Optimization

Translate communication system requirements into production-quality DSP software.
Debug complex system-level issues across DSP, firmware, RF, and hardware boundaries.
Analyze lab and field data to identify root causes of performance, stability, and interoperability issues.
Support product bring-up, validation, and long-term maintenance of deployed systems.

MIPS & Memory Optimization

Drive code-level optimization for MIPS efficiency and memory footprint on embedded targets.
Optimize algorithms 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 between computational complexity and system-level performance.

OFDM Modem Architecture

Lead architecture decisions for OFDM-based communication systems.
Evaluate and optimize system-level trade-offs involving bandwidth, latency, spectral efficiency, and robustness.
Ensure algorithm designs scale efficiently across multiple platform variants.

Technical Leadership & Team Development

Act as the technical authority for DSP and communication systems.
Establish and technically lead a DSP engineering team in India, including:

Mentoring engineers on algorithms, optimization techniques, and debugging methodologies
Defining coding standards, performance guidelines, and development workflows
Providing technical oversight and design reviews

Collaborate closely with RF, hardware, firmware, and systems engineering teams.

Required Experience and Skills

M.S. or Ph.D. in Electrical Engineering, Signal Processing, Communications, or a 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 with MATLAB, Python, and experience transitioning algorithms into embedded or real-time implementations.
Proven ability to debug complex, cross-domain issues in commercial products.
Strong communication skills and experience working with or leading geographically distributed teams.

Desired Experience and Skills

Experience with fixed-point DSP implementations and real-time operating constraints.
Embedded software experience on CPUs, DSPs, or SoCs.
Hands-on experience using RF lab equipment (signal generators, spectrum analyzers, SDRs).
Prior experience mentoring or leading offshore or distributed engineering teams.
End-to-end product development experience from concept through production.
