Senior Mobile Systems Engineer (iOS Focus)

Role Overview
The AppLogic Team owns the logic and interfaces that sit at the core of the Graykey platform. We’re the systems engineering layer behind the Graykey product. We make it work reliably across many devices, mobile operating systems, and product surfaces.

The work spans multiple platforms. Day to day, this role will spend significant time on iOS, but you should also expect to work on Android and on the Graykey product itself. We don’t silo people by platform. Senior Engineers on this team are expected to follow problems wherever they go in the stack.

This is a Senior, small, but mighty, hands-on Team. The work is technically deep and the platform knowledge required is real. You can’t build this kind of integration without understanding how mobile operating systems actually work underneath the API surface.

Mobile platforms change with every major release, and parts of what we do don’t exist in any public documentation. You need to be comfortable working in that kind of ambiguity.

NOTE: Candidate must reside in Canada.

iOS internals (!!!). This is the hard requirement. You need to have spent real time here, not just read about it:

iOS internals is a specialty in its own right. Android or other mobile platform experience is useful because the role also works on Android and on the Graykey product directly, but it does not substitute for iOS depth. Plan to bring iOS internals and pick up the rest on the job, not the other way around.

You DON’T need to be an Exploit Developer or Vulnerability Researcher. You DO need to read iOS internals fluently enough to integrate work into a product that runs across many device generations and iOS versions without breaking.

Python (!!!). Critical, not optional. We use Python extensively and at production scale. This isn’t scripting or tooling. You need to be strong here: type systems, packaging, performance, and writing code that doesn’t get rewritten by the next person to touch it. Python is load-bearing in this stack and weak Python in this role causes real problems.

Objective-C, C/C++, Systems programming, memory management, and low-level interface work. Meaningful time will be spent here.
