System Software Engineer (WFH)

About the job:

System Software Engineer

Role Overview

We're looking for a System Software Engineer with strong 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.
