At Apple, we strive every single day to craft products that enrich people’s lives. Our successes are the result of skilled domain experts working in an environment which encourages creativity, collaboration, and re-thinking of old problems in new ways! As a member of the Satellite Connectivity Group, you will work on the satellite network that enables connectivity to iPhone when off the grid without cellular or Wi-Fi coverage. Every day, Apple customers use Emergency SOS via satellite to access emergency assistance when they are in need of help and have no other means to communicate. You will have the unique and rewarding opportunity to shape this and other critical services, to the benefit and safety of millions of Apple device users. Our team is looking for an experienced software engineer with modern embedded C++ and Python skills and experienced in software-defined-radio and real-time data-processing systems. A successful candidate will be responsible for designing, implementing, testing, and operating a complex real-time software system that runs on a globally-distributed heterogeneous compute platform and processes every bit of information exchanged to realize the satellite connectivity.

DESCRIPTION

• Development of software-defined-radio system on Linux running on AMD/Xilinx SoC (C++, Python, shell). - Cross-team coordination and execution of software releases and hardware-software integrated test campaigns. - Development and deployment of operation procedures (Python or Go) running on the cloud-based control and monitoring system.

MINIMUM QUALIFICATIONS

• 10+ years of experience of software development in modern C++.
• 5+ years of experience of designing and implementing software-defined radio (SDR) software or high-bandwidth data-processing application.
• Experience of designing software system running on a heterogeneous computing system (CPU+FPGA, CPU+GPU, CPU+ASIC accelerator, etc).
• Strong familiarity with low-level systems programming using modern C++ constructs (C++20 and above) involving topics such as concurrency, memory safety, CPU-hardware interaction (including cache coherency management), and RPC / IPC / message passing.
• Knowledge of and ability to mentor other team members on modern design/coding best practices (e.g. C++ Core Guideline).
• Experience of development and publishing custom Python modules via an artifact storage such as PyPI.
• Experience of test automation, data analysis, and data visualization in Python.
• Experience of setting up a Yocto Linux or Petalinux project for a custom SoC board from scratch.
• Ability to write kernel-space user-space device drivers in C++ for high-bandwidth and real-time hardware accelerators / custom peripherals.
• Remote development / debug using modern tools (VSCode Remote, VSCode Debugger).
• Experience with operating complex software services on the cloud; development of test / operation procedures, real-time monitoring system, data-ingestion system, dashboard.
• Managed software releases to the production environment.

PREFERRED QUALIFICATIONS

• Familiar with AMD/Xilinx SoC and Vivado/Vitis/Petalinux toolchains.
• Previous experience of FPGA code development in RTL or HLS.
• General radio-frequency (RF) digital signal processing knowledge.
• Hands-on development experience in areas related to 5G, WiFi, GNSS, CCSDS, and/or SpaceWire.
