Job description

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

Forge is Deltatre's publishing platform — used by major sports leagues including the NFL, MLB, NHL, UEFA, and MLS to control content, presentation, and customer experience across their digital ecosystems. The Android engineering team builds the mobile and connected-TV applications that deliver Forge-powered experiences to millions of users on Android phones, tablets, and TVs.

As a Senior Android Engineer, you will work end-to-end on user-facing features — from translating designs into production code to optimising performance across a wide range of devices and screen sizes. You will help shape the Android side of the platform, contribute to architectural decisions, and coordinate Android engineers across regions.

Responsibilities

• Develop new user-facing features for Android using Kotlin and Java
• 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 mobiles, tablets, and connected TVs
• Analyse and simplify complex requirements to ensure efficient implementation; flag potential technical challenges to stakeholders early
• Coordinate the work of Android engineers across regions and contribute to engineering standards and best practice

Requirements

Requirements

You produce work that others can build on. You take ownership of features from design to production, and you write code that holds up under real-world device and performance variability. You are credible on architectural decisions because you have made them before and seen them play out.

Required

• 5+ years' relevant engineering experience, including a minimum of 2 years at Senior Android Engineer level
• Deep proficiency in Kotlin, with working command of Java
• Thorough understanding of the Android SDK and system framework APIs
• Experience with reactive programming using RxJava and its core principles
• Demonstrated unit-testing practice with JUnit and Mockito
• Solid grasp of mobile architectural patterns (MVC, MVVM, delegation, and similar)
• Familiarity with Google Play Services, Play Store account administration, and submission
• Knowledge of mobile debugging and optimisation techniques
• Comfortable with Git, build automation, and modern CI/CD practice
• Fluent written and spoken English
• Experience working with a global team or employer
• Experience with video playback in mobile or web applications; familiarity with video production, audio/video encoding, and transmuxing
• Experience creating frameworks or libraries embedded in other apps
• Basic knowledge of iOS or web programming platforms — useful for cross-platform context
• Knowledge of, or interest in, cricket — useful for editorial judgement on what the audience values

Who Thrives Here

Android engineering at Deltatre runs at the intersection of consumer experience and platform scale. The apps you build are used by millions of viewers across markets and device generations, and the technical decisions you make echo across that surface. The work rewards engineers who care about the small details — animation smoothness, 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 over multiple releases.

A good Senior Android 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 cross-platform decisions interact — what works for the Android user, what works for iOS, what works for the platform as a whole.

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. Easier doing it, more than explaining it.
