Senior Wireless Machine Learning Engineer, AI-RAN

Job Type

Full-time

Description

Type: Full-Time(W2) On-site/Hybrid, Arlington, VA (Remote option available for the right candidate)

Deep Sig is defining the future of wireless communications by merging deep learning with the Radio Access Network (RAN). We are seeking an experienced Technical Lead to architect and drive the development of our next-generation AI-native RAN.

In this role, you will design, prototype, and validate novel AI/ML components-such as neural receivers, neural beamforming, neural scheduling, digital twin, and ISAC (Integrated Sensing and Communications)-that outperform traditional signal processing methods. You will work at the cutting edge of 6G innovation, taking concepts from mathematical intuition to simulation (e.g. NVIDIA Sionna) and real-time implementation.

What You'll be Doing

• Applied AI Research:
  Design and train modern deep learning models (Transformers, Vision architectures, etc.) to solve complex physical layer problems, including channel estimation, MIMO detection, and beam management
• Simulation & Validation:
  Build high-fidelity link-level simulations using NVIDIA Sionna and ray-tracing to train, test, and benchmark AI models against legacy 5G baselines
• Prototyping & Deployment:
  Transition research models into deployable "dApps" for the Distributed Unit (DU), optimizing inference for latency and compute efficiency on NVIDIA GPUs
• New Capabilities:
  Explore emerging AI-RAN frontiers such as Integrated Sensing and Communications (ISAC), neural scheduling, and channel digital twins
• Innovation & IPR:
  Drive technical innovation by authoring invention disclosures, filing patents, and generating technical reports to support our standardization team in 3
  
  GPP and O-RAN Alliance contributions
• Data Engineering:
  Architect data pipelines for generating synthetic training datasets and developing "Sim-to-Real" transfer techniques to ensure robust performance in real-world networks

Required Qualifications

• Education:
  Ph.D. or Master's in Computer Science, Electrical Engineering, or Applied Mathematics with a focus on Deep Learning and/or Communications Systems
• AI/ML Expertise: 3+ years of experience designing and training deep neural networks from scratch. Strong grasp of modern architectures and optimization techniques
• Applied Signal Processing:
  Experience applying machine learning to real-time time-series data, signal processing, or physics-based problems (Audio, RF, or similar domains)
• Research to Code:
  Proven ability to read academic papers and implement their methods in robust Python code
• Simulation Skills:
  Experience with differentiable simulation or digital twins (e.g., Sionna, JAX-based physics sims)

Preferred Qualifications

• Wireless Knowledge:
  Understanding of wireless fundamentals (OFDM, MIMO, IQ data) is highly helpful, though we prioritize strong ML intuition over pure communication theory
• Performance Optimization:
  
  Experience with model quantization (FP16/INT8), pruning, or using Tensor
  
  RT for real-time inference
• Standardization Support:
  Experience writing technical whitepapers or supporting patent filings in a research environment
• C++ Integration:
  Ability to write C++ bindings or integrate Python models into C++, SIMD, and Cuda production pipelines
