Hardware Design Engineer (BLE & RF)

Overview

About the Role - We are seeking a talented Hardware Design Engineer (BLE & RF) who is passionate about wireless connectivity and embedded systems. The ideal candidate will bring a deep understanding of the BLE protocol , from stack to hardware, and combine it with practical expertise in debugging, optimizing, and validating BLE designs. You will play a pivotal role in ensuring our BLE-enabled products are robust, secure, and optimized for performance, from antenna and PCB design review to over-the-air packet analysis to security compliance.

Responsibilities

• Design and develop RF circuits, components, and systems for wireless communication products. Focus on design and validation of devices that use Bluetooth Low Energy (BLE) technology.
• Perform simulations, evaluate feasibility, and refine designs for enhanced efficiency.
• Analyze the test data, resolve RF issues, and implement improvements to enhance system performance.
• Perform simulation, modeling, and validation of RF circuit performance during development stages.
• Review and critique PCB designs for BLE modules, antennas, and RF paths to ensure optimal signal quality, range, and compliance.
• Debug and optimize BLE communication at all layers (PHY, Link Layer, GATT, Security), diagnosing issues like connection instability, latency, or interference.
• Perform detailed BLE security analysis , ensuring products comply with best practices for pairing, bonding, key management, and encryption.
• Capture and analyze BLE air traffic using sniffers (e.g., Nordic nRF Sniffer, Ellisys, or similar) to identify and resolve protocol-level or interoperability issues.
• Collaborate with hardware, firmware, and software teams to resolve cross-disciplinary issues.
• Write clear documentation and share findings with engineering teams, advocating for sound RF and BLE practices.
• Regularly implement best practices and remain informed about the latest developments in RF simulation.
• Stay current on BLE specification changes, new features (e.g., BLE 5.x / 5.4, Periodic Advertising, AoA / AoD), and trends in BLE security and RF design.
