Driven by a passion to innovate in the areas of sports performance, analytics and user experience, we have assembled a team of the industry’s top data scientists, sports performance scientists, product specialists and engineers. The company received recognition by Fast Company in 2019 as one of the most innovative companies in the world. Kitman Labs’ advanced Outcome-driven Analytics and Performance Intelligence Platform are used by over 700 teams in 50 leagues on 6 continents spanning soccer, rugby, American football, baseball and ice hockey.

We are looking for a Senior Android Engineer to join the mobile team within our Product Engineering group. As a senior member of the team, you won’t just be writing code; you will be a technical leader, helping to define our architectural roadmap and mentoring engineers to ensure we maintain a high bar of excellence. We write all new code in Kotlin and leverage the latest from the Jetpack ecosystem. We’re looking for someone who doesn’t just use these tools, but understands the "why" behind them and can advocate for the right tool for the job.

Your impact & responsibilities:

• Architectural Leadership: Lead the design and implementation of complex, scalable mobile architectures. You’ll ensure our codebase remains modular, testable, and maintainable as we scale.
• Product Strategy: Partner deeply with Product, Design, and Sports Science to turn ambiguous requirements into concrete technical roadmaps. You’ll build high-fidelity prototypes to de-risk new product directions.
• Operational Excellence: Own the end-to-end lifecycle of our apps. This includes obsessing over performance (app startup, frame rates, battery usage) and optimizing our CI/CD pipelines to ensure we ship high-quality code daily.
• Data Visualization: Design and build sophisticated tools that transform complex athlete data into intuitive, actionable insights.
• Mentorship & Culture: Raise the collective bar of the engineering team. You will conduct rigorous code reviews, lead technical discussions, and mentor mid-level and junior developers.
• Innovation: Actively research and pilot new technologies (e.g., Compose, KMP, or New Architecture components) to keep our stack at the cutting edge.

Experience and skills we look for:

• Extensive Lifecycle Experience: You have a proven track record of leading the development and maintenance of high-traffic, complex Android applications from inception to Play Store dominance.
• Kotlin Mastery: Deep expertise in Kotlin and the Android SDK. You should be comfortable discussing coroutines, flow, and memory management at a granular level.
• Testing Philosophy: Beyond just writing tests, you have experience defining testing strategies (Unit, Integration, and UI) that ensure long-term stability without slowing down development.
• System Design: Strong understanding of modern architectural patterns (MVVM, MVI, Clean Architecture) and the ability to articulate the trade-offs between them.
• Tooling & Infrastructure: Advanced experience with Gradle, CI/CD automation (e.g., GitHub Actions, Bitrise), and monitoring tools (Firebase, Sentry) to track app health in production.
• Technical Communication: The ability to explain complex technical concepts to non-technical stakeholders, ensuring alignment across the business.

Bonus Points:

• Platform Influence: Contribution to open-source libraries or active participation in the Android developer community.
• Cloud Proficiency: Experience integrating with Firebase to extend mobile functionality.
• Multi-Platform Vision: Experience or a strong interest in Kotlin Multiplatform (KMP) to share logic across iOS and Android.
• Performance Tuning: Experience using Profilers to debug memory leaks, jank, and overdraw.

Benefits:

• Competitive salary
• Health insurance for employee & dependants
• Meaningful equity
• Pension Plan
• Life Cover
• Income protection
• Wellbeing benefits

Location: While this role allows for remote work, occasional face-to-face gatherings are recommended.
