System Engineer – 5G NR / Wireless Systems
About Ananant Systems
Ananant Systems is building next-generation semiconductor solutions for 5G, connectivity, and intelligent edge computing. We are looking for a System Engineer to join our Systems team and contribute to the development of 5G NR physical-layer solutions from algorithm development through hardware and firmware implementation.
Role Overview
As a System Engineer, you will work on 5G NR L1 system modeling, algorithm development, simulation, and performance analysis. You will collaborate closely with digital design and firmware teams to translate wireless algorithms into efficient hardware and software implementations.
Key Responsibilities
Develop 5G NR L1 end-to-end reference models and link-level simulators using MATLAB and C/C++, covering both floating-point and fixed-point implementations.
Design, simulate, and analyze physical-layer wireless communication algorithms and evaluate system-level performance.
Work on L1 algorithms including channel estimation, signal estimation and detection, MIMO detection, synchronization, and forward-error correction.
Analyze algorithm performance across different channel conditions, configurations, and system parameters.
Develop and optimize fixed-point algorithms and models for hardware implementation.
Collaborate with digital design, architecture, and firmware teams to enable power- and area-efficient implementation of algorithms.
Translate system-level algorithms into clear feature descriptions, technical requirements, and implementation specifications for hardware and software teams.
Support system bring-up, debugging, and performance analysis through simulation and implementation correlation.
Contribute to technical discussions around 5G NR PHY architecture, algorithm trade-offs, and system performance.
Qualifications & Skills
Bachelor's or Master's degree in Electrical Engineering, Electronics, Communication Engineering, or a related field.
Strong fundamentals in Digital Signal Processing (DSP) and wireless communications.
Good understanding of 5G NR Physical Layer (L1) standards and procedures.
Hands-on experience with common wireless L1 algorithms such as:
Channel estimation
Signal estimation and detection
MIMO detection
Synchronization
Forward-error correction
Strong experience in MATLAB-based link-level simulation and system modeling.
Proficiency in C/C++ for algorithm development and modeling.
Experience with fixed-point algorithm development and optimization.
Ability to analyze simulation results and translate them into practical implementation requirements.
Strong problem-solving and analytical skills.
Good communication and ability to work effectively with cross-functional hardware, firmware, and systems teams.
Good to Have
Experience in wireless semiconductor / chipset development.
Experience working on 5G NR modem or PHY development.
Experience taking algorithms from system modeling to RTL/hardware or firmware implementation.
Knowledge of 3GPP 5G NR specifications and modem architecture.
Experience with performance optimization considering power, area, throughput, and latency.
Experience with real-world 5G testing, prototyping, or modem bring-up.
Location
Bangalore / Noida, India
Candidates should be comfortable working from either of our Bangalore or Noida offices, depending on the team and project requirements.
What You Will Work On
You will be part of a cross-functional team working across wireless systems, digital design, firmware, and silicon implementation, with the opportunity to contribute to the development of next-generation 5G semiconductor products.
