About Head Spin

Head Spin provides a global device infrastructure and performance intelligence platform used by engineering and QA teams to test, monitor, and optimize mobile and web applications at scale. Our platform gives teams real-device access and deep network and performance telemetry — and the engineers who build it work at the intersection of systems programming, mobile internals, and distributed infrastructure.

Role Overview

We're looking for a System Software Engineer with deep systems and networking expertise to work on the core infrastructure that connects Head Spin's platform to physical i OS and Android devices. You'll own the protocols, daemons, and communication layers that make real-device automation, remote debugging, and telemetry collection possible at scale.

What You'll Do

Design and maintain the device connectivity stack — including USB and network-based device sessions using usbmuxd, remoted, and Apple's Core Device/Remote XPC framework

Build and extend low-level communication layers that interface with i OS internals (lockdownd, DTService Hub, XPC services)

Develop system-level daemons and services on Linux and mac OS that handle device multiplexing, session management, and protocol translation

Work with transport protocols (TCP, QUIC, HTTP/2, Web Socket, 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 i OS 17+ shift from usbmuxd/lockdownd to remoted/Remote XPC) and adapt the platform accordingly

What We're Looking For

5+ years of systems-level software engineering experience

Deep knowledge of network protocols: TCP/UDP, QUIC, TLS 1.3, HTTP/2, HTTP/3, Web Socket

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/g RPC protocols and Web RTC

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 (Wire Guard, IPSec)

Prior work on test automation infrastructure or mobile Dev Ops platforms

Hands-on experience with i OS device communication protocols: usbmuxd, lockdownd, Remote XPC, Core Device
