At Apple, the Satellite Connectivity Group is looking to solve the problem of providing connectivity to iPhone and Watch Ultra when users are off the grid without cellular or Wi-Fi coverage. This involves developing and operating a complex real-time software system that processes all information exchanged to enable satellite connectivity for critical services like Emergency SOS, Roadside assistance, and Messages via satellite.
Requirements
- Modern embedded C++ and Python skills
- Experienced in software-defined-radio and real-time data-processing systems.
- 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.
- Experience of development and publishing custom Python modules via an artifact storage such as PyPI.
Responsibilities
- 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.
- 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.
- 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.
Other
- Skilled domain experts working in an environment which encourages creativity, collaboration, and re-thinking of old problems in new ways!
- Knowledge of and ability to mentor other team members on modern design/coding best practices (e.g. C++ Core Guideline).
- 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.
- Managed software releases to the production environment.
