Job description

Overview

For this role you must be able to work on a hybrid basis with at least 2 days per week working in the Mumbai office in Andheri.

Position

AXIS is Deltatre's user experience management platform — used by BritBox, Sportsnet+, DYN, Bell Media, beIN, and other OTT operators to control native app experiences across iOS, Apple TV, Android, and the long list of streaming devices. The iOS engineering team builds the applications that deliver AXIS-powered experiences to millions of consumers on iPhone, iPad, and Apple TV.

As a Senior iOS Engineer, you will work end-to-end on user-facing features — from requirements refinement through architecture, implementation, and release. You will help shape the iOS side of the platform, contribute to architectural decisions, and coordinate iOS engineers within your team.

Responsibilities

• Refine and estimate requirements; contribute to product and engineering planning
• Develop new user-facing features for iOS and Apple TV using Swift
• Build reusable components and libraries for future use across the platform
• Translate designs and wireframes into high-quality production code
• Optimise components for performance across iPhones, iPads, and Apple TVs
• Define and contribute to the architecture of digital solutions
• Plan delivery effectively — robust, modular, testable code
• Coordinate the work of iOS engineers within the team
• Contribute to Deltatre engineering procedures, code conventions, and best practice
• Stay current with developments in iOS and UI engineering relevant to the platform; the team works to Scrum methodology

Requirements

You produce work that others can build on. You take ownership of features from refinement through release, and you treat the iOS platform as a craft — not only a delivery target. You make architectural decisions that hold up over multiple release cycles, and you document them clearly enough that the team can use them after you have moved to the next problem.

Required

• 5+ years' relevant engineering experience, including at least 2 years at Senior iOS Engineer level
• Recent hands-on experience with SwiftUI (2+ years)
• Deep proficiency in Swift
• Thorough understanding of Apple system frameworks — Foundation, UIKit, AVFoundation, StoreKit, and others
• Demonstrated unit-testing practice with XCTest
• Familiarity with Apple app submission, code signing, and iTunes account administration
• Comfortable with instrumentation testing and optimisation
• Comfortable with Git, build automation, and continuous integration
• Fluent written and spoken English
• Experience working with a global team or employer
• Experience with libraries commonly used in the team — Alamofire, BrightFutures, emitter-kit, Kingfisher
• Familiarity with Facebook SDK, Fabric, Crashlytics
• Experience with In-App Purchase implementation
• Background in the sports domain
• Genuine interest in Apple TV development

Who Thrives Here

iOS engineering at Deltatre runs at the intersection of consumer experience and platform scale. The apps you build are used across multiple device generations and major broadcast events, and the technical decisions you make echo across that surface. The work rewards engineers who care about the small details — gesture responsiveness, memory pressure, the moment when a stream buffers and the user makes a decision about the platform — and who can hold the longer-arc view of how the codebase evolves.

A good Senior iOS Engineer at Deltatre tends to be honest about technical debt without being doom-laden, generous with knowledge transfer to less senior engineers, and curious about how platform decisions interact across iOS, Apple TV, and the wider product.

Process and what to expect

• Introductory conversation: a step for us to get to know each other better, and for us to answer all questions you might have around Deltatre.
• Take-home assessment: a practical exercise you complete in your own time, designed to show us how you approach a real engineering problem. We will use it as the basis for the technical conversation.
• 1-hour Technical round of Interview: we will deep dive on your experience and on the take-home assessment, and explore the technical decisions you have made in your past work.
• 1-hour Competency Based Interview: we will ask you situational questions around how you deal with real-life scenarios at work.

If any of these formats would be difficult for you, tell us — we adjust regularly and can usually accommodate.

Accessibility and accommodation questions are welcome at any stage. Tell us what would work for you.
