iOS Systems & Full-Stack Engineer

HeadSpin is a global digital experience intelligence and omnichannel testing platform supporting quality assurance for mobile, web, and OTT experiences, leveraging data analytics and AI/ML insights.

Location: India (remote)

Responsibilities

• Backend API Development (50-60%): During key infrastructure sprints, you will focus heavily on building, scaling, and maintaining the Python or Go services.
• iOS Core Development (40-50%): Design and maintain complex iOS applications and frameworks using Swift and Objective-C.
• System-Level Engineering: Deep dive into iOS internals (processes, security, and automation frameworks) to support custom hardware or software integrations.
• Backend Integration: Develop, test, and maintain robust, scalable APIs in Python (FastAPI/Flask) or Go to support mobile features and data synchronization.
• Ecosystem Troubleshooting: Provide high-level technical support for the entire Apple stack, including code-signing, provisioning, MDM (Mobile Device Management), and CI/CD pipelines.
• Collaboration: Work closely with infrastructure teams to ensure mobile devices are correctly isolated and containerized within our broader service environment.

Requirements

• Expertise in Swift and a strong working knowledge of Objective-C.
• Deep understanding of iOS Internals: Process management, keychain, background tasks, and system performance tuning.
• Experience with XCUITest and mobile automation tools (e.g., Maestro, Appium, or custom XCTest runners).
• Mastery of the Apple Deployment cycle: Certificates, Provisioning Profiles, App Store Connect, and TestFlight.
• Proficiency in either Python or Go.
• Experience designing RESTful or gRPC APIs.
• Knowledge of Docker and containerization strategies for isolating service environments.
• Understanding of networking protocols (WebSockets, HTTP/2, SSH tunneling).
• Good understanding of Design patterns and Data Structures and Algorithms.
• Minimum 4 years of software development experience in IOS development and backend technologies.

Additional Information

• Support-Oriented: Willingness to provide "on-call" or deep-dive technical support when Apple ecosystem updates break existing workflows.
• Architecture First: Ability to write Architecture Decision Records (ADRs) to justify tech stack choices.
• Security-Conscious: An instinctive understanding of why we isolate device-manipulation scripts in Docker for security.
• Knowledge of macOS Virtualization (Tart, Anka, or Apple Virtualization Framework).
• Contributions to open-source mobile tooling.
