About Jian Jet Zhu

A versatile Research & Development leader and AI-driven Engineering Orchestrator with over 15 years of experience specializing in mobile device localization. I blend deep domain expertise in 3D hybrid tracking with advanced AI tooling (LLMs, Copilot, multi-agent architectures) to accelerate product development, resolve critical production crises, and act as a force multiplier for my teams.With a proven track record of bringing positioning systems from prototype to field-deployed RESTful APIs, I thrive at the intersection of complex RF data analysis, multi-modal sensor fusion, and strategic team leadership.Specialties:• AI-Driven Engineering & Crisis Management: Leveraging IDE-based AI and multi-agent orchestration to rapidly diagnose infrastructure flaws, reverse-engineer legacy systems, and rescue failing production deployments under strict customer deadlines.• Team Leadership & Orchestration: Managing remote, cross-functional teams (Research, DevOps, Integration), segmenting complex projects, and scaling enterprise AI workflows.• System Performance Optimization: Error source analysis, Estimation theory, Kalman Filter applications, and RF propagation modeling. Uncovering deep hardware/firmware issues (e.g, gNodeB Timing Advance bugs).• Hybrid Positioning Technology: Fusing Barometer, Wi-Fi, BLE, IMU, GNSS, and Cellular signals. Designing Edge-caching location proxies and local fusion engines.• Data Mining & Architecture: Integrating mobile apps, backend microservices, and databases for massive data acquisition. Parsing and analyzing complex telemetry (e.g, Nemo log transformations).More Details:• Who am I? Named Jian and called Jet from Zhu\'s family in Beijing. Father of two. An optimistic problem-solver who enjoys what life has to offer.• What am I doing? Improving 3D location accuracy and availability for mobile devices across the most challenging environments (urban canyons, tunnels, subways) by fusing every available signal—especially where traditional systems fail.• Who I am working for? Logistics, industrial automation, autonomous driving, and first responders. My work is verified by CTIA-Stage Z location testbeds to provide z-axis estimation within 3m @ 80% of the time, helping E911 callers when they need it most.

Experience

1. Director of Research, Positioning and Tracking

   Polaris Wireless

   Aug 2021 — Present · Santa Clara, CA, US

   Crisis Leadership & AI Turnaround: Rescued a failing production positioning engine during critical customer acceptance testing following the sole domain expert\'s sudden departure. Leveraged IDE-based AI to rapidly diagnose core algorithmic flaws, dropping baseline error from 600m+ to <200m in Phase 1. Orchestrated a Phase 2 team-led core logic rewrite, achieving 78m offline accuracy to beat the strict <100m customer target.• AI Operations & Orchestration: Championing enterprise AI adoption. Designed and deployed a \"Dual-Engine\" AI architecture and multi-agent workflows to automate massive data parsing pipelines, accelerate R&D, and act as a force multiplier for the engineering team.• Cross-Functional Diagnostics: Bridged the gap between theoretical specification and real-world implementation. Successfully isolated persistent positioning errors to underlying hardware issues, uncovering vendor gNodeB firmware bugs failing to report precise Timing Advance (TA) values.• Product Delivery & Pre-Sales: Doubled (2x) positioning accuracy for a high-stakes product demo via AI-assisted development, successfully securing engagement and contracts with critical potential customers.• 3D Location System Evolution: Directing a 6-person cross-functional team to elevate an over-the-top z-axis system into a dynamic, autonomously learning 3D location database.• System Architecture: Designed edge-caching proxies with local fusion engines to drastically reduce API overhead. Spearheaded the productization of the Z-axis RESTful API and an Android UI/intent data-collection app.• Strategic Leadership: Define the positioning research roadmap, manage resource allocation for advanced studies, oversee Beta solution releases, and provide continuous mentorship to engineering teams.
