Responsibilities

Wifi / Bluetooth Software Engineer is responsible for developing and delivering Bluetooth and Wifi software for multiple Apple Products.
This involves developing state-of-the-art device drivers for firmware, perform board bring-up and HW validation, review HW schematics and assist HW debugging.
You will also support factory testing, resolve critical issues on-site, perform modem SW integration, and stabilize the baseline.
Work closely with partners like HW, RF, Protocol, and QA as well.
Design, develop, and maintain automated testing frameworks using Python, applying object-oriented programming principles, data structures, and algorithms to ensure wireless connectivity across Apple's product ecosystem (iPhone, iPad, Watch).
Implement comprehensive test suites leveraging Python libraries and frameworks to validate new wireless features, protocols, and technologies, utilizing software engineering methodologies and testing strategies learned through specialized technical training
While considering computer architectures, processor fundamentals, and hardware constraints, conduct performance analysis and benchmarking of wireless software components, applying statistical analysis and data interpretation techniques to identify bottlenecks, optimize system performance, and ensure seamless 24/7 connectivity for end users
Collaborate with cross-functional engineering teams to identify, reproduce, and debug complex wireless software issues, utilizing debugging tools, version control systems (such as Git), and software development best practices
Design and execute automated calibration workflows for WiFi and Bluetooth radios using embedded test equipment (LitePoint, Spectrum Analyzers), developing Python-based automation scripts to interface with test instruments via SCPI/API commands, perform RF measurements (transmit power, receiver sensitivity, EVM, spectral mask), and validate calibration data against Apple's stringent quality specifications across production device variants.
Develop data acquisition and analysis pipelines to collect, process, and visualize RF measurement data from LitePoint and spectrum analyzer test sessions, implementing Python scripts using libraries (NumPy, SciPy, Pandas) to perform statistical analysis on calibration results and generate automated pass/fail reports with traceability for manufacturing and engineering teams.
Maintain and optimize Jenkins-based continuous testing infrastructure for WiFi and Bluetooth validation, creating parameterized Jenkins jobs that orchestrate test execution across multiple embedded test stations, implement parallel test scheduling to maximize throughput
Experience in HW and SW development and Integration, utilizing C and C++ for RTOS-controlled firmware, along with virtual memory, concurrency, threads, locking, synchronization, and scheduling
Investigate, prototype, and deliver new and innovative system solutions
