System Software Engineer

Role Overview

We're looking for a System Software Engineer with solid systems programming and networking expertise to develop and maintain the core infrastructure that connects software platforms to physical iOS and Android devices. This role focuses on building and managing the protocols,

daemons, and communication layers that enable real-device automation, remote debugging, and large-scale telemetry collection.

What You'll Do
Design and maintain the device connectivity stack — including USB and network based device sessions using usbmuxd, remote, and Apple's

CoreDevice/RemoteXPC framework
Build and extend low-level communication layers that interface with iOS internals

(lockdownd, DTServiceHub, XPC services)
Develop system-level daemons and services on Linux and macOS that handle device multiplexing, session management, and protocol translation
Work with transport protocols (TCP, QUIC, HTTP/2, WebSocket, RPC) and apply them in the context of high-reliability device tunneling
Collaborate with platform and product teams to expose device capabilities —

screenshots, logs, crash reports, network HAR capture — reliably and at low latency
Keep pace with Apple's evolving device communication model (e.g.,



the iOS 17+

shift from usbmuxd/lockdownd to remoted/RemoteXPC) and adapt the platform accordingly

What We're Looking
5+ years of systems-level software engineering experience
Deep knowledge of network protocols: TCP/UDP, QUIC, TLS 1.3, HTTP/2, HTTP/3, WebSocket
Proficiency in Python and Go
Experience with POSIX systems programming: sockets, process management,

multithreading
Experience debugging with lldb, dtrace, Wireshark, or similar low-level tools
Understanding of network stack/OSI model and devices/protocols falling under each layer -

MAC/ARP, IP, ssh/scp, DNS, SSL/TLS
Experienced in developing REST API, websockets, RPC/gRPC protocols and WebRTC
Solid understanding of Unix system, OS internals and networking

Nice to Have
Experience with libimobiledevice or similar open-source device tooling
Knowledge of Android's adb protocol and USB debugging stack
Background in VPN/tunneling (WireGuard, IPSec)
Prior work on test automation infrastructure or mobile DevOps platforms
Hands-on experience with iOS device communication protocols: usbmuxd, lockdownd,

RemoteXPC, CoreDevice[5.
